The Junk Food Doctor: "This Food Is Worse Than Smoking!" & "This Diet Prevents 60% Of Disease!" - Chris Van Tulleken (Ultra-Processed People Author)

[0] I ate a diet that's very normal for a British person.

[1] I gained so much weight.

[2] Got in this vicious cycle of overeating, anxiety, sleeplessness, scanned my brain, and if I'd continued for a year, I would have been Dr. Chris Van Tolkien.

[3] Doctor researcher and a BAFTA reward -winning broadcaster.

[4] Chris forensically examines the effects ultra -processed food have on us all.

[5] 75 % of the calories that are consumed globally come from six companies.

[6] Food Mafia.

[7] They are controlling our food and what we eat.

[8] engineered to be consumed to excess.

[9] Whether it's a burger from a fast food chain or a supermarket bread, everything is adjusted so that things become irresistible.

[10] And a pandemic of diet -related diseases has taken over the world.

[11] One in five people in this country get 80 % of their calories from ultra -processed food.

[12] Poor diet has overtaken tobacco as the leading cause of early death on planet Earth.

[13] And by the age of five, kids in this country will be that much shorter, nine centimetres compared to other countries.

[14] And it is all diet.

[15] You can't stunt a body by nine centimetres and not also stun them intellectually.

[16] Why don't we just all make better choices?

[17] I have almost no interest in personal responsibility.

[18] This is about social justice.

[19] And people without money, they're forced to eat bad food.

[20] If you've got rid of poverty, you would get rid of around 60 % of the problem of diet -related disease.

[21] What about the people that say this is just about calories in calorie out?

[22] There are two very big problems with that.

[23] And this is very good, robust science.

[24] The first is that...

[25] And if people are listening and they want to lose weight, the evidence says...

[26] Dr. Chris Van Telekin.

[27] You wrote a book, Ultra Processed People.

[28] I know from first -hand experience that writing books is a painful experience.

[29] It takes a long, long time to do it.

[30] And you have an extensive experience across medicine, across different sort of scientific disciplines.

[31] Why does this book and this subject matter matter to something?

[32] society and maybe even more importantly why did it matter enough to you it matters to all of us because for a very long time we've been incredibly confused about what to eat and we've called the foods that harm us junk food and processed food and high fat salt sugar food we've we've not had a way of labelling foods even as a pandemic of diet related disease has taken taken over the world really And this is particularly true now in low -income countries and particularly true with low -income people living in the UK.

[33] So poor diet, which means a diet high in ultra -processed food, has overtaken tobacco as the leading cause of early death on planet Earth.

[34] For humans, the animals we farm, and for wild animals, of course, because ultra -processed food is produced by a food system that is the leading cause of loss of biodiversity, the second leading cause of carbon emissions, and the leading cause of plastic pollution.

[35] So about 12 years ago, the definition was developed to describe a Western industrial American diet.

[36] And it was done by a team in Brazil.

[37] And much of the best work on this stuff has been done by teams in Central and South America.

[38] Because what they saw in those countries, whereas this has crept up on us in the UK, in places like Mexico and Colombia and Brazil, obesity was essentially unheard of.

[39] And within a decade, it went to being the dominant public health problem.

[40] In towns in Mexico, you wouldn't know anyone who was living with obesity, and within a decade, everyone would know someone who'd had an amputation for type 2 diabetes.

[41] The only thing that had changed was the influx of broadly an American diet, industrially processed foods.

[42] So the definition was invented 2009, 2010, and we've had a decade of evidence now that is very clear that it is ultra -processed food, that is responsible not just for pandemic weight gain, and obesity but also for a long list of other health problems including early death why did this matter so much to you what is the personal reason here i've i'm an identical twin i've got a brother who lived with obesity for a very long time and i would my weight would fluctuate i'm i'm insulated by by privilege by my surroundings by education but i'm always on the brink of weight gain and i recognized in myself uh that i lived with an addiction to many ultra -processed products, and my brother particularly did.

[43] And so at the core of the book is, was this sort of moment of understanding where I, there are several sort of fulcrums in the book, I suppose, but two of the key elements are, first of all, for many of us, ultra -processed food isn't just harmful, it is addictive, and it makes all the criteria for addiction, and it has, there's so much evidence that for some people, these products are as addictive as tobacco products, drugs of abuse, alcohol, gambling.

[44] but that nagging people is really, really harmful.

[45] So I'd had a very toxic relationship with my brother.

[46] And in fact, the whole family, we're a very close family.

[47] But we had, for the better part of a decade, be nagging him to lose weight.

[48] And I took him to see a behavioral change expert who said to me, I don't need to speak to, I need to speak to you.

[49] I said, no, no, he's the fat one.

[50] You've got to speak to him.

[51] He said, no, you are the problem.

[52] For your brother to lose weight will be to lose an argument that's been a decade long with you.

[53] you are the barrier.

[54] And so because I'd been nagging him, I owned his problem and he didn't own it.

[55] And so at the heart of the book is this idea that nagging people generally pushes them towards doing things that are harmful.

[56] It generally makes them more likely to do the thing you're nagging them about.

[57] And I've tried to engage with these products.

[58] When we come to individual solutions, I've tried to engage with ultra -processed food as an addictive substance, a substance that I was addicted to.

[59] What is the balance there between personal responsibility and being a victim of circumstance in the sort of food landscape and society that we live in?

[60] Because there's obviously been a huge debate around obesity and weight.

[61] You know, there's one school of thought maybe over on the more extreme side that says just get out there and, you know, make better choices in your life and go, I don't know, go for a run or something.

[62] And then there's another school of thought that says weight gain and obesity are a byproduct.

[63] product of genetic, our genes, and the environment we live in.

[64] What is the truth in your view?

[65] And in the case of your brother?

[66] I think we have really, really good evidence.

[67] That personal responsibility, these arguments around willpower and personal responsibility are morally, scientifically and economically redundant.

[68] They have no value.

[69] So when it comes to population health, There are loads of different ways we can argue this.

[70] If we look at willpower, insofar as it's ever been operationalized for research, and there's not a huge amount, the research, and you will know some of this, the research is quite nuanced, but broadly it serves as a proxy for poverty.

[71] So the original marshmallow experiments, which I think you've talked about, where you offer a child, a marshmallow and say, we'll give you another one if we come back in five minutes and you haven't eaten this one.

[72] that experiment those children who were unable to resist the marshmallow went on to really suffer in life they had much across all kinds of different indicators their lives were much more troubled they had lower achievement economically and socially what it turned out is when you adjusted for maternal education the effect went away in other words the kids who were taking the marshmallow were from poor households and they were making a sensible choice they were taking an opportunity when it arose, because if you come from a situation of deprivation or disadvantage, often things that are promised never materialized.

[73] So once you controlled for that in the studies, broadly, your ability to resist a marshmallow age four predicts the household you're from.

[74] You might be from a low education, low income household.

[75] It doesn't predict anything else.

[76] So that's one way of looking at willpower, and there's lots of other evidence.

[77] The other thing is that if we look at weight in the mid -1970s, and this is, you know, American government data, there was a sudden inflection in weight gain where the obesity pandemic took off around 1975.

[78] And you look at a graph, it's bumbling along, it's suddenly everyone goes up.

[79] When I say everyone, black, white, Hispanic, men, women, you know, five -year -olds, 50 -year -olds, 90 -year -olds.

[80] Everyone starts gaining weight.

[81] So unless you're going to propose when it comes to weight gain, that there was some failure of moral responsibility in young Hispanic men and older black women and middle -aged white people, you know, that just doesn't stack up.

[82] What changed was the food environment.

[83] So my feeling is the only thing that it's interesting to talk about is the structure of the society around us.

[84] And we have really good evidence that when you simply give people money, when we've done this, this research has been done by economists, by doctors, by social scientists.

[85] When you give people money, they make smart choices.

[86] Rich people don't eat bad food because they don't want to eat bad food.

[87] And people without money eat bad food because they're forced to eat bad food.

[88] And the cognitive dissonance that you and I were talking about, quite often we will find people with low incomes making quite cogent arguments about the food that they eat, appearing to side with the companies that are predating on them.

[89] Because otherwise, how could you live with this dissonance in your life?

[90] Otherwise, you're just a powerless victim of transnational food corporations.

[91] So I have almost no interest in personal responsibility.

[92] I think you, if you give people technical knowledge and you give people income and opportunity, most people want to be healthy and live good lives.

[93] 1970, the food environment changes.

[94] Can you tell me exactly how the food environment change that caused multiple demographics to gain weight?

[95] There are two answers to that.

[96] One, the sort of proximate.

[97] ultimate reason is the invention of ultra -processed food.

[98] So the industrialization of food supply.

[99] And you can talk about why that happened in a lot of different ways.

[100] Part of it was to, you know, a booming population post -war.

[101] And these products were extremely convenient.

[102] They allowed women to continue to be in the workplace.

[103] Of course, women had entered the workplace in the war.

[104] So there were a lot of things that were immediately appealing about these products.

[105] TV dinners, Swanson TV dinners appear in the 50s, and by the time of the 70s, these products had become very widespread.

[106] So in the same thing, we were a decade behind in the UK, but this stuff is now our national diet.

[107] Why exactly it took over is the subject of a lot of the research I'm doing at the moment.

[108] So now I work much more with economists, the nutritionists, and what we see is the financialization of the food industry.

[109] So the primary determinants of almost every action that happens in almost every food company that supplies, say, 90 % of our calories, all the indicators are financial, and not to do with public health.

[110] And so we can use financial indicators.

[111] We can use financial research to show that the food industry does these things like buy cheap debt, use that to do share buybacks, rather than generating value.

[112] We can show that they vote down, activist investors, will vote in institutional investors, We'll vote down public health proposals at shareholder meetings.

[113] And so part of it is the takeover of the food system from being a system where people would grow a lot of their own food, make food at home.

[114] They buy ingredients from local shops to a small number of companies supplying food.

[115] So now 75 % of the calories that are consumed globally come from six companies.

[116] There are about 15 to 20 companies that make most of the food we eat in the UK, that process the food.

[117] So we've got a very small number of agribusiness producers that make more or less 12 things that we eat broadly, pigs, cows and chickens.

[118] Those are our meats.

[119] We don't really eat other meat, maybe a bit of lamb, maybe, goat, maybe, goose, not really, duck, perhaps.

[120] So we eat really three meats.

[121] And then our main sources of calories come from four or five crops.

[122] Corn, rice, wheat, soy, palm bit of sunflower so the human diet which should encompass thousands perhaps tens of thousands of different species of thing has now because of the pressures of of commercial efficiency become reduced to a very small number of companies with enormous power producing making a very small number of food products and needing to generate intellectual property kind of like sounds like a mafia of sorts like a food for you.

[123] I'm going to let you say that.

[124] Yeah.

[125] No, don't sound like me say it.

[126] I don't want them coming for me. I think it's, I don't mean it to sound malevolent.

[127] So the argument I've just made can sound a bit neo -Marxist or anti -growth or anti -capitalist.

[128] And I really don't mean it to sound like that.

[129] But it is important to understand the incentives within the system.

[130] And if the incentives are financial, you'll end up with ultra -processed food.

[131] So the logic of the food is the cheapest possible ingredients with the longest possible shelf life and maximum intellectual property.

[132] What is ultra processed food?

[133] So broadly there are three types of food.

[134] There's unprocessed or whole food, which might be like an apple or an oyster or you can drink milk out of a cow.

[135] You shouldn't because you get brucellosis, but you can do it.

[136] That's whole unprocessed food.

[137] Then there's processed food.

[138] So there's butter.

[139] So we can take whole milk.

[140] We can process it into butter or cheese.

[141] Now we've been doing that.

[142] So North African pastoralists started doing this in the Sahara region, maybe 7 ,000, 8 ,000 years ago started making dairying.

[143] And if you can make butter, you get all the fat soluble vitamins from milk.

[144] You get very high calorie and it almost never goes off.

[145] It's really long shelf life.

[146] Similarly cheese, add a bit fermented, add some salt.

[147] You get a long shelf life, very nutritional product.

[148] So those are processed foods.

[149] And we've been eating processed foods for over a million years.

[150] I mean, humans are the only animals that have to process their foods.

[151] You know, food processing has shaped our jaws, our teeth, our guts.

[152] So compared to any animal of similar size, we have tiny little teeth, minuscule, fragile jaws, very short guts, because we've extended our digestive tracts out of our bodies and into our kitchens.

[153] We chop food rather than chewing it.

[154] We cook it rather than digesting it.

[155] So our food is predigested.

[156] So processed food is good.

[157] Tinning, canning, concentrating, fermenting, salting, smoking.

[158] All these projects, techniques were invented really by women over hundreds of thousands of years working in caves and huts and shelters and then kitchens.

[159] They produced modern food.

[160] And diets from the high Arctic to sea mammal diets from the high Arctic, pescatarian diets in East Asia, vegan diets of South Asia, any traditional diet you point to is basically associated with good health, all of them.

[161] They've all evolved in different ways.

[162] Same is true of French cuisine, rich in butter and red wine.

[163] The only diet that we've studied that really seems to bring health harms is an ultra -process diet.

[164] So that is the American financialized industrial diet.

[165] So ultra -processing is about using these commodity ingredients that I just listed, you know, commodity ingredients like soy, corn, rice, and a bit of meat, reducing them into powder form, So if you grow corn, the market, I mean, you understand all this much better than me. You get money and finance.

[166] The market for cobs of corn, spread with butter and salt, it's pretty limited.

[167] If you grow cobs of corn, you can sell a few of them.

[168] But if you can turn the rest of them into corn starch, which you can modify and turn it.

[169] So it's like you can create any chemical property that starch you want.

[170] You can turn it into corn oil and you can turn it into high fructose corn syrup.

[171] Suddenly you have the ingredients for every single food product on the planet.

[172] it.

[173] So the logic is to take your corn, break it into pasts and powders with an infinite shelf life, then recombine them with additives, texturize them, flavor them, put a brand on it, and then you can add just enormous value.

[174] And a lot of the ingredients we see in ultra -processed food are waste products from old food processing.

[175] So the weigh proteins we see in our nutritional powders.

[176] I mean, this was a waste product from dairy.

[177] You know, it used to be spread on fields or fed to cows.

[178] But now the value you add, instead of it being used for fertilizer, the value you add when you turn it into a nutritional supplement is a thousandfold, probably more than a thousand fold.

[179] Citrus fiber.

[180] You'll see citrus fiber is an ingredient in a lot of bars.

[181] Sounds healthy, doesn't it?

[182] Like it's, you know, citrus fruit, fiber, what could be, and it probably is reasonably healthy.

[183] It's left over from the juice, the juicing and tinning industries where you have to get the peel off fruit and if you put it through a set of chemical processes you can extract the fibre add it to the human food chain and create enormous value so the logic of ultra -processed food really is about creating products with intellectual property that use the cheapest ingredients you can that will last for a long time and from what I understood there the that last process so step three so you had whole foods then you had processed foods then you had ultra -processed foods and then the ultra -processed foods category.

[184] What they're doing is taking the good stuff out and putting some bad stuff in.

[185] Is that a simple way to think about it?

[186] I would think, I think that is a very simple way.

[187] That's a straightforward way of thinking about it.

[188] The additives are not really the problem.

[189] So the problem, I would say, some of the additives we think are harmful.

[190] We've got some quite good research around some of the artificial sweeteners, some of the modified starches, Xantham gum, the emulsifiers, and some of the colorings and texturants.

[191] Then we have some research that says the fact the food is mechanically processed so hard, it's generally very soft.

[192] So think of any ultra -processed food you can, whether it's a burger from a fast food chain or a breakfast cereal or supermarket bread.

[193] Generally these calories are soft and they're energy -dense because they're dry, and so dry food is important for shelf life.

[194] The softness and the energy density means you consume them very quickly, and so you essentially consume them before you become full.

[195] And so that's one of the ways they drive over excess eating.

[196] So if you like the laundry list of the ways in which the food harms us is softness, energy density, some direct harms from the additives, a lack of phytonutrients, so it doesn't contain much real food.

[197] And real food, real plants and animals should have a great variety.

[198] of molecules and chemicals that we don't understand very well, but vitamins from a plant seem to interact with you very differently than vitamins in an extract.

[199] But the main thing is the way the foods are developed.

[200] So I spoke to so many people in the food industry, who were all wonderful, by the way.

[201] You know, I've really enjoyed most of all talking to them.

[202] But the food scientists all said the same thing.

[203] The products are generally put through a focus group.

[204] So you start with your box of cereal that you've been making for decades.

[205] And you have formulation A. And then you make a new formulation, formulation B. You put it through the focus group.

[206] If the focus group eats box B quicker than box A, box B is the one that goes on the shelf, because if they eat it 5 % quicker, you'll sell the box is 5 % faster.

[207] That's, that's the financial indicator.

[208] And so it's not any one aspect of the food that's harmful so much as when the intention is to create products that people will use as much as possible, then you end up with addictive food.

[209] Interesting.

[210] The food is put through, if you like, almost a Darwinian evolutionary process, where every single thing, every dial is tweaked on every product, every few months, everything is adjusted from the sweet, salt, sugar ratios to the texture in the mouth, to the color of the packet, and everything is dialed up to 11 so that things become irresistible.

[211] And maybe you don't live with this, but people who, many people listening, will recognize in themselves that there are products that they cannot stop eating.

[212] They fantasize about them.

[213] They think about them.

[214] And once they start eating them, they will consume five adult portions.

[215] And I've got a six -year -old and a three -year -old, and my six -year -old can eat five adult portions of any sugary breakfast cereal in about 20 minutes.

[216] I brought some food along with me today.

[217] I'm looking at it.

[218] Because I wanted to get your...

[219] It's not distracting.

[220] I wanted to get your opinion on it.

[221] So I brought a group of food products on the left here.

[222] Now, these are things that I, I think, growing up, I thought were good.

[223] Yeah.

[224] So, you're very bold with these brands.

[225] I mean, you're really limiting sponsorship opportunities.

[226] Well, you know, you know, I do think about that sometimes, but I also don't really care.

[227] I think, like, I'm in the pursuit of truth here.

[228] So much of why I do this is to educate myself.

[229] And I think if I educate myself, then I'll help educate other people.

[230] That's why I'm also okay being a total idiot on this subject matter, because that is the truth.

[231] So here I've got four products that are typically seen as being quite healthy.

[232] Breakfast cereal, Cheerios, I grew up thinking, good for me. Actamol, good for me. Diet Coke.

[233] Great, because there's no sugar in there.

[234] And then this is whole grain.

[235] Whole grain bread.

[236] 50 % of your daily whole grain in just two slices.

[237] Great.

[238] perfect so for a start i have a slight unease i'm going to talk about these products i have a slight unease talking about any one product sure the evidence applies to the category of food and this kind of stuff in a sense i think you're abs these are such brilliant choices because this is the foundation of our diet and one of the things that's happening at the moment is is the food industry exploring painting me as a snob because i'm i'm critiquing these sort of core things you know tins of beans with flavoring or supermarket bread, fish fingers.

[239] I think this stuff is at the shallow end of the pool in a way.

[240] It's not by any means the worst stuff.

[241] But in a way, it presents the biggest moral hazard because we think it's so healthy.

[242] I love the Diet Coke.

[243] Yeah.

[244] So Diet Coke is my is my favorite example because this is the ultimate health food according to the way we label food at the moment.

[245] It has four.

[246] Where's the camera?

[247] It's all green.

[248] It's four green traffic lights, right?

[249] What does they call that, that traffic light system?

[250] So this is the way we describe whether a food is healthy or not in this country at the moment.

[251] And this system is quite influenced by the food industry, and it breaks all foods down into fat, saturated fat, sugars and salt, and says that, you know, if those are the bad things, and if a food is high in them, it'll have oranges and green.

[252] So if you look at the Cheerios, they're mostly on the front, it's on the front.

[253] It's optional, by the way.

[254] so it's not always on every packet but the Cheerios are oranges and greens.

[255] Now, there is a baked in confusion to this because what do you do at a traffic light that's orange and green, or red orange and green?

[256] Do you go?

[257] Do you stop?

[258] Is it on the actamil?

[259] It's not on there.

[260] No, I couldn't see it on that.

[261] Maybe on the bottom.

[262] It's optional.

[263] So who knows if, you know, we don't have any way in this country of describing either healthy food or unhealthy food other than these traffic lights.

[264] Anyway, this is a healthy food.

[265] Now, if we look at the ingredients on the Diet Coke, carbonated water, fine.

[266] Now, there's a color called caramel E150D.

[267] Caramel.

[268] It makes you think of traditional.

[269] It's a French 19th century invention, burn sugar, creme brule.

[270] It's like, it's a bit naughty, but it's fine.

[271] Caramel E150D has nothing to do with caramel.

[272] It is carbohydrate treated with a mixture of acids and, and, uh, and heat to produce things that contain ammonium and sulfite.

[273] So it's a food additive color with no benefits, nothing to do with caramel.

[274] Artificial sweeteners, aspartame, and asosulfame K. Now, sweeteners are tricky because we know sugar is harmful because it rots teeth and it promotes weight gain because it makes you eat more.

[275] The weird thing about sweeteners is they don't seem to help with weight loss at all.

[276] They may, some of them seem to be more metabolically harmful than sugar itself.

[277] Humans are quite good at eating sugar.

[278] When we lollipops continuously as kids or have sugary drinks, it's not good for us.

[279] But human societies have for millennia existed with a huge amount of honey and refined carbs.

[280] So sugar we can handle, although we should reduce our intake.

[281] Sweetness are quite weird because they're a nutritional lie.

[282] You put sweet taste on the tongue, which says to your body, sugar is coming.

[283] So maybe put up some insulin.

[284] maybe start preparing in other ways physiologically to receive refined carbohydrates.

[285] And when that refined carbohydrate, when the sugar never arrives, it seems to be physiologically confusing.

[286] So the World Health Organization now says sweetness aren't better than sugar when it comes to weight loss.

[287] And there is an anxiety about Aspartame and cancer that I'm personally not in a big sweat about.

[288] There's some evidence, but not at normal doses.

[289] Then we've got natural flavorings.

[290] We've got caffeine flavoring, an addictive drug.

[291] and phosphoric acid and citric acid.

[292] Natural, it said.

[293] Natural flavorings.

[294] I mean, you know, well, flavorings are flavorings.

[295] Flavorings should signal nutritional content.

[296] When you eat a tomato, it has flavor, not for fun.

[297] It has flavor because it signals the nutritional content of the tomato.

[298] When you put flavorings out of context, even if you extract them from the tomato or the strawberry or the peach, it's very confusing for you physiologically.

[299] You have a very sophisticated internal system to link.

[300] flavor molecules, which are broadly smell, and taste molecules, salt, sweet, bitter, sour, and some savory ones, your body has a way of linking all that information with nutritional information that you get from your gut subconsciously.

[301] When you muddle it all up in a product like this, it's very confusing.

[302] The phosphoric acid will dissolve the minerals out of your bones as well as dissolving your teeth.

[303] So what we have here is a solution of flavorings and addictive drug, an acid that will leach stuff out of your bones, and sweeteners that seem to be metabolically confusing and certainly aren't better than sugar.

[304] And yet we think of this as a health product.

[305] So that for me is the archetypal, confused way of thinking about food.

[306] And what we also know is that when it comes to kids the age of my youngest, so the age of three, they're drinking on average one can of artificially sweetened drinks every single day.

[307] So we've taxed sugar.

[308] sugar has come out of our diet we've seen no weight loss no indication that it's helping health and what we are doing is consuming huge numbers now of these artificial sweetness which we also know affect our microbiome what is a better alternative that's popular on the market than because it appears to me that all of the drinks in the bloody supermarket have artificial sweeteners and flavourings and they do because of the sugar tax so it's almost impossible now to buy fizzy tax without sweeteners to buy fizzy drinks drinks without sweetness.

[309] So for kids, I try and not give any advice to anyone ever, but my kids, my kids eat a lot of UPF, but they don't have fizzy drinks.

[310] I think fizzy drinks are really quite harmful across the board.

[311] So kids should just drink milk and water, milk if they can have it.

[312] And grown -ups can do pretty well on milk and water if you drink milk.

[313] What about breakfast cereals and Cheerios and things like that?

[314] So breakfast meals are really convenient.

[315] I mean, let me see the Cheerios.

[316] So I think these, these probably do meet the definition.

[317] Yeah, these do meet the definition.

[318] So we've got things like palm oil, caramelized sugar syrup, colors, an Atonorbixin, and an antioxidant.

[319] So this is ultra -processed.

[320] It'll have some fiber.

[321] You'll have it with whole milk.

[322] I don't want to demonize breakfast cereals.

[323] My kids eat breakfast cereals for breakfast, but it's not like eating porridge, which is just whole grains or real bread.

[324] This is, and what you will find is if you give this to a kid compared to porridge, they will be able to eat much, much more of this.

[325] And there is a lot of marketing that this is a really, really healthy product.

[326] And I would say the evidence says that this falls into a category of foods, that we actually know are associated with negative health outcomes.

[327] It says on the side there, doesn't it, a list of all the health benefits.

[328] A really good way of telling if a food is ultra -processed is if there is any health claim on the packet, it's almost certainly ultra -processed.

[329] And part of that is to do with this intellectual property thing that the only food you can make lots of money out of is a branded product.

[330] So there's no money in broccoli, milk, steak, eggs.

[331] Supermarkets quite often make losses on all those things.

[332] There's no health claim on broccoli.

[333] or on plums or on milk there's no health claim on steak it's only the ultra -process things that you get marketed to you in this way because there's enough money to do it the actamel's interesting as well the immune support well it says immune support and it says vitamin d and b6 so that rich in vitamin d immune support that is definitely healthy i mean this is this is a this is where we need we should have done the maths and shown how much sugar there was in each pot.

[334] These are very high calorie shots of sugary liquid that will harm teeth.

[335] And I don't know why you'd have this if you could just have real yogurt and or milk.

[336] And the reason they back add the vitamins is to be able to make health claims.

[337] So generally foods with added vitamins, real food doesn't need added vitamins.

[338] And we're, again, we're pretty sure that.

[339] And I'm conscious who I'm talking to here.

[340] I've got, I'm, I'm, I'm, I probably have to tread a bit carefully.

[341] Supplementing vitamins into food doesn't seem to have many health benefits for healthy people.

[342] So we've got quite a lot of very big data on this.

[343] And there are lots of studies that show benefits that are funded by people who make vitamins.

[344] But broadly, the independent evidence shows that, But when you get vitamins and minerals in the context of food, they're really good for you.

[345] And when you take them in pill or supplement form, they don't seem to have many benefits if you are healthy.

[346] And this food here, this bottle of Coke, I've got can of Pringles and Coco Pop's Kellogg cereal.

[347] This is the stuff that I typically think of is like bad, processed, ultra -processed, stay away from.

[348] You would, but give me the Coca -Pops.

[349] So the Coco -Pops, we look at these traffic lights, okay?

[350] green, green, orange, orange.

[351] Pretty healthy.

[352] I mean, there is a, there is a monkey on the pack selling it to my, to my kids.

[353] Yeah, it says high in vitamin fiber, vitamin D, iron.

[354] Yeah, iron.

[355] Supporting your family's health, rice added goodness.

[356] I mean, everything about this tells you that this is a product not just safe for kids, but intended for kids.

[357] And we'll know you're like, you can't sell things if they're not healthy.

[358] There must be some regulator dealing with that.

[359] And this is the thing that my six -year -old will eat five adult portions of.

[360] So when you eat five adult portions, the traffic lights only apply to a 30 -gram serving for you.

[361] Now, a 30 -gram serving is a handful like that.

[362] It's one big spoonful.

[363] Okay.

[364] So this is the product that I recognize addictive behavior in my kids.

[365] And frankly, myself, I mean, I could eat, you know, 300 grams of it.

[366] And the other thing that I went and got from the supermarket, because I was thinking about what I typically think as ultra -processed and good for me, I went and got this frozen pizza here.

[367] And then I went and got a Tesco's finest, so this is high -end, you know, much more expensive, not -frozen pizza.

[368] And I thought, surely, this pizza here is a lot better for me than this one here.

[369] So again, there's a complexity talking about is one better than the other because we've never done a trial, testing them against each other.

[370] They're both ultra -processed.

[371] I know because I've looked at the ingredients.

[372] They both contain ingredients that you don't have in a domestic kitchen like palm fat or dextros.

[373] And they're both made really, in a sense, by the same company.

[374] So they're both made by PLCs who will be owned by institutional investors with the requirements for growth.

[375] So they come from the same food system with the same incentives about production.

[376] And my bet is that you or I would be able to eat the entire pizza at a single sitting and we'd be still licking the pack of both of them.

[377] So this is food that in a sense is engineered to be consumed to excess.

[378] You did an experiment, didn't you?

[379] Quite a famous experiment now where you put yourself on an ultra -processed food diet.

[380] Can you tell me about that experiment and the symptoms that you saw when you did lived off ultra -processed food pretty much exclusively?

[381] So I ate a diet that's very normal for a British teenager.

[382] I ate 80 % of my calories from ultra -processed food.

[383] So for a teenager in my kid's school, for example, this would be a completely normal thing to do.

[384] One in five people in this country get 80 % of their calories from EPS.

[385] So I wasn't really putting my body on the line.

[386] I was switching from 20 % to 80%.

[387] Kind of two really big things happened.

[388] There was some health effects.

[389] So in terms of the physical effects on my body, I gained so much weight.

[390] And it wasn't supersized me. I wasn't forcing it in.

[391] This was done as part of a scientific experiment for a big study that I'm now running at University College London where I work as an academic.

[392] I gained so much weight that if I'd continued for a year, I would have doubled my body weight.

[393] We scanned my brain before and after.

[394] I worked with colleagues at the National Hospital for Neurology and Neuroscience, so neurology and neurosurgery.

[395] So these were scans done very expertly.

[396] And while I'm only one patient, you can subtract the noise.

[397] You can be very sure that what you see is real.

[398] We saw enormous increases in connectivity between the automatic behavior habit bits, the back of the brain, and those reward addiction bits right in the middle of the brain.

[399] So we can't exactly say what's happening.

[400] but certainly behaviours and rewards are getting much, much more connected.

[401] Most significantly, I think, we saw a change in my hormonal response to a meal.

[402] So when you eat real food, whilst you're eating, you're chewing, all kinds of hormonal and neurological changes happen in your body that will come to a point they'll say, look, you've had enough, Stephen, you're fine, you can stop eating now.

[403] And that's called satiety, and we've evolved this mechanism since living things first started eating food hundreds of millions of years ago.

[404] And all animals have it.

[405] humans have it too.

[406] What we saw is that at the end of a standard meal at the end of this month, my hunger hormones remain sky high.

[407] So this is food that is interfering with our bodies' evolved mechanisms to say, I am done, it's time to stop eating.

[408] But there was this other thing that happened, kind of the most important thing, and it's at the core of the book, is that midway through this diet, which I was quite enjoying, you know, if you're sort of middle -aged man, you know, the quest is always to lose weight.

[409] And I could go.

[410] back to eating the foods of my childhood and I was eating hot wings and all this stuff that I hadn't eaten for years.

[411] I was really enjoying it.

[412] But I was also doing all this research, partly for the book and I'm, you know, as a scientist, I study nutrition.

[413] And I was talking to a colleague in Brazil called Fernando Raub, and she just kept saying, this isn't food, Chris.

[414] It's an industrially produced edible substance.

[415] And I sat down that evening to meet, eat a meal of takeaway fried chicken and I could hardly finish it.

[416] And she had flicked this switch in my brain where all of this ultra -processed food had become disgusting.

[417] But I then had to keep eating it for another fortnight.

[418] And so it was a bit like the very famous book, The Easy Way to Quit Smoking, where you smoke all the way through reading the book while you learn about smoking.

[419] And by the end of the diet, I mean, I now don't want to eat any ultra -processed products.

[420] So the gift I'm trying to give the reader is if you're living with a dick, my invitation at the beginning is eat along eat while you read don't forbid this stuff to yourself let yourself wallow in it immerse it taste it and you'll start to and read the ingredients lists while you eat and you'll realize that all the food is it has the same flavor profile it's all equally salty and sugary and sweet it's all acidic and you will gradually become disgusted and that's not a promise that seems to be what's happening to a lot of people and that is a very well evidence technique when it comes to living with addiction.

[421] So the World Health Organization, who I work with, recommends the easy way to quit smoking for quitting smoking as being as useful as patches or any other technique.

[422] So for the individual, treating it as an addictive substance may be really useful for some people.

[423] What was the impact on your sort of mental health and how you felt from a sort of psychology perspective?

[424] Because I, you know, we've seen this huge rise in sort of of mental health diagnoses across the board, especially in younger, younger people, but it seems to be pretty consistent throughout different ages and demographics.

[425] And I wondered if there's a link between ultra -processed foods and mental health crises that we're living through.

[426] We've got really good epidemiological data.

[427] So we now have hundreds of prospective studies, which are the best, the kind of studies we use to link smoking to cancer, that it is not just associated with physical ill health, metabolic disease, inflammatory disease, cardiovascular disease, cancers, early death.

[428] It's also associated with anxiety, depression, and also dementia.

[429] And my experience of being on the diet was that there was a thing that I think the research doesn't capture, which is because it's salty, I was getting up to pee more at night.

[430] And I was, I don't know if I can say this, I was getting really constipated and uncomfortable because it's quite low in fiber.

[431] And so I got in this vicious cycle of sleeplessness, and I'd often find myself where at the fridge in the kind of small hours at the morning, and the food felt like the solution to the problem.

[432] So I got in this spiral of sleeplessness, anxiety, overeating.

[433] And we know that stress and elevated cortisol also generally increases your desire for low quality food and makes people overeat.

[434] So in a way, that kind of middle -aged stress, anxiety, there's sort of mild mental health symptoms that so many people live with, often it is just driven by the food.

[435] I read this stat in your book that according to the World's Obesity Federation, 51 % of the world or more than 4 billion people will be obese or overweight within the next 12 years.

[436] So I like to say they will live with obesity rather than use obese as an adjective because I think the biggest problem for people who live with obesity is stigma.

[437] It's that being a...

[438] Obes is your identity.

[439] And what we actually know is the, the World Abysity Federation are doing some really good work, identifying this as the major public health problem.

[440] The ticklishness talking about this is it's really hard to say that obesity is a problem without also saying that people who live with it are the problem.

[441] If you're not careful, a war on obesity becomes a war on people who live with it.

[442] And I think the evidence is very clear.

[443] It's just about the food environment.

[444] So, yes, you can make these very very, powerful economic arguments that we simply cannot afford to have a food system that's driving this rate of disease.

[445] I think the moral arguments are much more powerful that this is stuff that causes human suffering.

[446] So I would not actually tax ultra -process food, and I certainly wouldn't ban it.

[447] I think all my arguments are about increasing freedom, increasing choice, increasing opportunity.

[448] And that's quite conscious.

[449] I mean, you know this as a skillful communicator.

[450] And you talk about kind of doing exactly this in your book, where I'm trying to make an argument that will appeal to the political right that are much more on the side of, you know, free market, low regulation.

[451] And in fact, we can have regulations completely compatible with huge economic growth.

[452] And what I'm asking for is a food system where people with low incomes have access to healthy, affordable food.

[453] Because a lot of people would say, and this is sort of part two of your book, that, okay, so the solution here is really just for people to make better choices when they're, I don't know, in their fridges or when they're walking through a supermarket.

[454] Why don't we just all make better choices?

[455] I mean, you will, you may have a much more profound, I think you're asking this question in a provocative way.

[456] I think you will understand it much better than me. I've always had choice.

[457] And so when I choose to buy things, they're unhealthy it is with a degree of choice i do my my patients um i run a clinic at the hospital for tropical disease where i work and most of my patients have no addresses they're very disadvantaged they're migrants asylum seekers um they come from very low -income families because those are the people who get infections now when i say to them go and eat some healthy food they all know what healthy food is they've often got very the very diverse community have often got very rich traditions of healthy food from the communities of the cultures they've come from, they are completely unable to buy it.

[458] In the case of the asylum seekers, they're eight pounds a day and they can't work.

[459] You can't say to someone, spend your eight pounds a day on apples and broccoli and meat, they haven't got knives to cut it with.

[460] And we know a million households in this country don't have fridges, freezers, stovetop cookers.

[461] So there are a huge number of families that only have a microwave to cook.

[462] And fresh food, While there is always a politician willing to advance this argument, like, but you can buy a bag of lentils.

[463] If you go to the cash and carry, you can buy rice or lentils for, you know, a couple of quid for 10 kilos, it costs money to heat it.

[464] It costs time.

[465] Time is the most expensive thing for people with low incomes.

[466] They need pots, pans, cutting boards, knives, tupperware.

[467] If you're going to batch cook, which is the only way to make home cooking economical, you've got a deep freeze to store it in.

[468] So saying to people with low incomes, you know, make health.

[469] choices it is it is nonsense it's just it's and so a bit i feel very strongly it the world does not need another person like me saying that and in fact no one we all people hate being told what to do there was a study done on toddlers in 1920 that you write about which is quite illuminating where they got to choose their own food from a selection of unprocessed foods and the children instinctively chose their own diet which met their nutritional needs and calorie intake What was that experiment and what does that indicate to us about the nature of this argument as it relates to just being able to control what we eat and choose what we want?

[470] If we look at the animal kingdom, even if you look at something you might think has quite a simple diet, like a big herbivore living in, you know, any of the big herbivores living on any of the big plains of the world.

[471] And you think, well, they just eat grass.

[472] They don't.

[473] We've done loads of experiments where you put, it sounds a bit unkind, but you put a hole in the neck of the animal and you put a bag on the hole and you collect the plants they're eating.

[474] And you can do this in a way that's relatively humane.

[475] And what we discover is if we study goats or cows, they're eating 50 or 60 different plants a day.

[476] Calories are abundant.

[477] And what those animals are doing is balancing all their nutritional needs from all those different plants and selecting them and learning them about the flavor profile and the mineral content.

[478] They're moving to avoid predators in the rains to different soils.

[479] So animals are incredibly sophisticated at perfectly balancing their nutritional needs from their environment.

[480] And obesity is non -existent in the wild animal kingdom.

[481] In urban animals actually start to scavenge from humans, there is some evidence of obesity.

[482] But in wild animals, there is no obesity.

[483] Humans, it turns out, obviously have the same ability.

[484] And so a scientist called Clara Davis, who's an amazing woman.

[485] She was a gay woman, one of the first medical graduates in North America.

[486] And she did this experiment where she was taking abandoned kids in essentially functioned almost like an orphanage.

[487] And each child got access to 34 different whole foods every single day.

[488] And it was things like there was raw bone marrow and cooked rice and yogurt and milk and they had a little bowl of salt they could have as much or as little salt as they wanted.

[489] And her question was, could the kids balance their nutritional needs?

[490] And the best example was a kid called Earl, who she took in a few months old and he came in with ricketts.

[491] So he had very bad vitamin D deficiency, had bendy bones.

[492] and they did some x -rays and you could see the rickets on the x -rays.

[493] And every single day, he would glug an entire cup of cod liver oil, which at the time was one of the only, really the only source of vitamin D. And he'd drink this every single day, enthusiastically.

[494] He always wanted his coddive oil.

[495] And on the day his rickets were healed and you couldn't see them anymore on the x -rays, he stopped drinking the cod liver oil, never asked for it again.

[496] And none of the kids without vitamin D deficiency would drink, would touch the codilver oil.

[497] overall.

[498] So something in Earl's body was saying, I will, when I need this stuff, I'll have it.

[499] Once I don't need it anymore, I won't have any more of it.

[500] And all the kids that she studied over many, many years with access to a full range of foods perfectly matched, all their nutritional needs, they all grew really well.

[501] They were intellectually well developed.

[502] They're extremely healthy.

[503] And they didn't have any of the sort of food refusal problems that the parents have nowadays.

[504] So, and she knew very well that the point was the kids only had access to good food.

[505] She wasn't giving them access to industrially processed junk foods, which were still slightly available in the 20s.

[506] It was a really cool experiment.

[507] For me, I take away from that, that our bodies can kind of self -regulate what we need if they're in an environment where the options are good.

[508] So if I'm a parent, and I'm sure I'll be a parent in the next couple of years, I hope so, if I just make sure in my house, all the food options are good for my kids, whole foods, all the good stuff you've described.

[509] Presumably, then I can just unlock the cupboards and let them run free.

[510] I love talking to people who might become parents about what they think me. I mean, I'm like, wow, you just, I mean, yeah, good luck to you.

[511] Can we have this conversation again in about six years?

[512] Can you tell me why I'm...

[513] Well, you're not wrong.

[514] you're completely right it will be impossible for you to limit the influx of ultra -processed food into your house so clearly i've written the book on this i study this i would love to do that i want my kids to be normal being normal is really important as a kid and food isn't just stuff we put in to build our bodies food binds us to the people around us food is part of our community and our culture in the uk our food culture is ultra -processed food and if you don't eat and drink ultra -processed food, you become a slightly odd person.

[515] And so I still eat it when I go to friends' houses because otherwise I look like some, you know, fanatical food snob.

[516] So, and it's the same with my kids.

[517] So grandparents, friends, relatives, all bring it around.

[518] You don't control what they eat at school.

[519] You know, my youngest ones are a really nice nursery, but it's still ultra -processed food from the minute she gets there to when she leaves.

[520] So very good luck to you.

[521] But this is why I argue, I nod to, if an individual wants to read my book, I think they will come away with technical knowledge that they will be able to use.

[522] And I wish them well with that.

[523] The big argument of the book is about, this is about social justice.

[524] You know, it is, it is really appalling that even for people with a lot of means, real food is incredibly affordable and unavailable.

[525] what about the people that say this is just about calories in calorie out the you know fitness community a lot of the weight loss community just say what you've got to do and I've actually got a friend that said this to me quite passionately he says what I do is I just measure the amount of calories I'm taking in measure the calories that are coming out and I make sure that there's a calorie deficit and if you have a calorie deficit he actually said to me one day he goes you can eat whatever you want and you'll be fine mathematically he's he's not entirely wrong.

[526] There are some very, very, there are two very, very big problems with that.

[527] The first is that while some people can just eat to instructions, many of us have genes that lead us to engage with food in a more interesting way.

[528] You know, I care about food.

[529] I love food.

[530] I'm driven to it.

[531] So you, your friend should come around my house in the morning with a box of cocoa pops and try and get my daughter to eat one adult portion and good luck to him.

[532] I mean, they'll be screaming and crying and she'll be grabbing the box.

[533] So the food, it's a bit like saying to smokers, all you have to do is just smoke one cigarette.

[534] Don't smoke the whole pack, just have like one to be social.

[535] Or people who live with addiction to alcohol, well, just have one drink and that won't do you any harm.

[536] The food really is addicted for many people.

[537] But there is this other bit of the equation, which is really fascinating, which is that when we do more activity of the kind that most of us do, it doesn't seem to have an normal impact on the calories that we burn.

[538] And this is very good, robust science.

[539] Going back to the, going back to the 90s, the most, if I tell this as a story, which I think is the way you'd do it, there was a scientist called Herman Ponser, and he wanted to know how many more calories he'd burn if he went and lived as a hunter -gatherer with the Hadza tribe in Tanzania.

[540] So he went and studied them and he used the thing called double -labeled water where you can measure very accurately a calorie expenditure and he put them in metabolic hoods and he studied them for months and he came back and he looked at his data and he thought he'd got it all wrong because the data showed that for essentially if you or I went and lived in Tanzania and we walked 15 kilometers a day hunting antelope and digging tubers out of the ground we wouldn't burn any more calories per day and he just could not make sense of this so then he went back and looked all the data available in the literature we've studied animals we've studied different human populations there are We've studied subsistence farmers compared to secretarial workers in the States.

[541] We've looked at minors.

[542] The same thing is true in all the studies.

[543] When you do sustained activity over a long period, it doesn't massively impact your calories.

[544] Now, some exceptions.

[545] If you do polar expiration, if you cycle in the Tour de France, if you go to the gym for an hour and a half every day, six days a week, you probably do burn a few more calories.

[546] But activity of the kind we all do doesn't seem to.

[547] And that explains why exercise is good for us.

[548] because if you don't do exercise, I burn 3 ,000 calories a day, let's say with slightly different body compositions, but roughly you and I burn 3 ,000 calories a day.

[549] If you do your hour and a half of exercise every day, you're stealing energy from your other budgets.

[550] You're taking it away from inflammation, away from hormones, and away from anxiety.

[551] That's why exercise seems to be good for us.

[552] Because I'm sitting here, and I'm readily to be said in truth, with my two kids.

[553] I don't go to the gym for an hour a day.

[554] So I spend my calories, but they're spent on inflammation and anxiety and relatively high hormone levels.

[555] And is this what we call the fixed energy model?

[556] I read that in your book that term.

[557] Yeah.

[558] So that's, that's, that's, that's the model.

[559] And there are lots of exceptions.

[560] But what that model tells us, along with all the other available data, is that when we are talking about populations who live with obesity, increasing activity will be really good for them, but it will not have a significant effect on body weight.

[561] So when we're talking about the pandemic of obesity, activity isn't hugely important.

[562] And if people are listening and they want to lose weight, many people have the experience that putting a healthy diet in the context of lots of other healthy things is often really a good way of bringing about behavioural change.

[563] You'll feel good in other ways.

[564] But the activity in the exercise, if you think that putting in your slog at the gym, most of us can manage 40 minutes every other day tops and I get nowhere near that it's not going to have an impact on your weekly calories even if even if we accepted that that even if we did think that it increased the number of calories you burn there's other evidence that says you you either eat more because your your body isn't just the mathematical machine that your your friend proposes but also if you add up the calories and you go to the gym for half an hour four times a week it's just not very many calories in terms of your weekly calories unless even if you're cycling as hard as you can for the whole thing i can i can definitely relate i i work out every day because just because i if i didn't every day if i did you set you seven days a week i have a pt every single day and the reason i do that is purely because i am best disciplined when i have a clear routine so knowing that it's part of my habit and that it's actually today it's in my calendar yesterday it was in my calendar even i even have lunch in my calendar now because I'm just trying to make sure that I have some kind of routine with my eating or else I just won't eat.

[565] I remember on Friday, my first meal was at 6pm because I was podcasting, had some stuff with the BBC and I don't want to do, I don't want to eat before I do anything because I'll slump.

[566] My point here though is with my personal trainer every day, if I don't change my diet, very little happens with my body.

[567] Actually, I end up growing a bit more muscles, I end up getting a bit stronger.

[568] But in terms of weight loss, the fat just sits there.

[569] Interestingly, though, from a psychology perspective, I've spoken to a lot of scientists and doctors who have said, your body will basically overcompensate for what you've just burned if you went, go for a five or ten mile run.

[570] Your body wants to defend its weight because that's defending its survival chances.

[571] For me, one of the things that happens is if I go out, go and work out in the gym, because it was so painful, I'll then come home and look at the flapjack or the cookie or whatever.

[572] And I'll think that's two steps backwards.

[573] That's interesting.

[574] Whereas some people will come home and look at the flapjack and go, I've earned that.

[575] But to counterat my own point, that also happens sometimes.

[576] I go, well, I can have it because I just ran or whatever.

[577] What I might do is I might avoid the flapjack, the obviously bad thing, but then I might eat more of something that I think isn't bad.

[578] Do you see what I'm saying?

[579] You'll have a sort of nutritional bar or something that is sold to you as being part of that kind of access.

[580] Yeah, and I'll eat four of those.

[581] But when you speak to, one of the really interesting things is when you speak to nutritionists, and I've spoken to a couple who worked with really elite sports teams, those athletes generally eat food.

[582] So they have chefs that make, and they might make quite an elaborate flapjack, but it will be a flapjack made with the ingredients you would have in your kitchen.

[583] And they will often drink milk while they're cycling or running.

[584] and they'll eat pieces of chicken rather than other things.

[585] This topic of willpower, again, we kind of started with it.

[586] I love, because willpower comes up a lot in your stuff and it's been so interesting listening to your stuff about it.

[587] I have to be honest, I have evolved in my thinking about it because I've listened to both sides of the argument around willpower, and it does appear to me that there is probably something else going on.

[588] But with all these studies on willpower, it's hard to establish causation, because there are other factors that are quite clearly could confound the variables in place.

[589] So it's something that I've gone back and forward on.

[590] You talk about twin studies in the context of royal power and what that can teach us.

[591] Why did you talk about twin studies in Chapter 9?

[592] Part of it was done by a colleague called Clare Llewellyn.

[593] And what Claire was looking at was the herit, it's a bit convoluted.

[594] Let me see if I can do this.

[595] The heritability of a beastly genes.

[596] So there's a weird thing.

[597] We see this with, it's a bit easy to understand with IQ, but it's true of IQ genes and obesity genes.

[598] But in some places, if your parents have genes for obesity, you will have a 90 % chance of inheriting the obesity.

[599] But in other families, it's more like 10%.

[600] Same is true with IQ.

[601] So what Claire Llewellyn showed was that if you came from a situation of deprivation, if you came from a low -income household, your genes for obesity are much more likely to be expressed.

[602] So you would inherit those, you'd inherit those genes and you would develop obesity.

[603] Now the social importance of this was because IQ studies originally showed that intelligence was hereditary.

[604] And this caused huge problems because it was done in the States and minority groups were measured as having lower intelligence.

[605] And this provided that kind of core argument of saying, well, some people are genetically less intelligent.

[606] And there's a woman called Sandra Scar, and she did the first intelligence, first studies, and it was twin studies that showed it, were that whilst intelligence is heritable in some communities, it isn't in others.

[607] And basically it works like this.

[608] If you come from a well -off household, all your genes, whether they're for a healthy body shape or for intelligence, they're all maxed out.

[609] And so all the variability is genetic in the population.

[610] If you come from a low -income household, you might have genes for height that never get expressed.

[611] You might have genes for intelligence that because you have been poorly nourished, you haven't been as educated as well, those genes for intelligence never get expressed.

[612] So you have a really complicated picture where genes can be inherited but not expressed in different communities according to how those populations are treated.

[613] And so that's one of the crucial things in psychology is when we only study white middle class populations, when we study psychology students, we get very, very different answers to when we go and look at populations who live with disadvantaged or low income.

[614] So essentially one of the big findings from Claire Llewellyn's work is if you got rid of poverty, you would get rid of around 60 % of the problem of diet -related disease.

[615] And you and your brother, because you are twins, are quite a good example of this, I guess, because you reference how he went and lived in Boston and was having a stressful time and gained weight.

[616] I mean, every time I go to America, we travel out there to record the podcast.

[617] It's just absolutely fucking wild.

[618] I just feel terrible.

[619] I always gain weight.

[620] And it's just unavoid.

[621] If you're doing work like you do in the States and you're at hotels and you're on the move and you're traveling, you cannot eat.

[622] good food.

[623] That mini bar in the bloody hotel, which they just keep topping up.

[624] I remember, I was saying to the team, I was like, I put the cookies in the fucking bin, and then I came back the next day and they'd put two bags there.

[625] Yeah, they think you've eaten the cookies.

[626] Yeah, they thought I enjoyed them.

[627] I mean, the marketing, that's a form of marketing.

[628] And if you think that you are struggling, I'll come back to Boston, but if you think that someone like you struggles in a hotel room when they've put cookies and all this junk there and you have to sort of put out of sight.

[629] For a British teenager, this is true for teenagers in states, Canada, Australia, they are saturated in marketing in a way that would be completely invisible to you and I. I mean, you may remember this from childhood.

[630] It's on your bus tickets.

[631] When you buy stationary at the shop, it'll be on your receipt.

[632] It's on your music apps because we pay for our music apps, but kids don't.

[633] It's on their social media.

[634] The companies get their phone numbers directly from they enter competitions, and then they send them meal deals and messages ping, ping, ping, to their phones.

[635] So they, it's 360, 24 -7 immersion in marketing of addictive products.

[636] And so it's, it's not that confusing why 25 % of British kids live with obesity, not just overweight.

[637] Anyway, so Boston, yeah, my twin moved to Boston.

[638] It was a situation of some stress.

[639] He'd had a kid, a son, Julian, with someone in a way that wasn't planned, I I suppose.

[640] Julian knows this.

[641] I mean, Julian's a whole, it's all part of a very dear family now.

[642] But it was very stressful.

[643] He went there to do a master's degree.

[644] He lived above a burger shop.

[645] And he, he kind of ate his problems and he gained 30 kilos.

[646] And that, that is an example of we both have a genetic vulnerability.

[647] But my life in the UK was very stable and I was in a different food environment in the UK.

[648] You move my genes, my clone, genetically were identical.

[649] You move my clone to the states stress him out a bit he gains 30 kilos i mean it's it's nothing has our willpower changed has our personal responsibility changed you know a set of um accidents and and uh coincidences and the food environment of what determined his weight there's nothing to do with willpower at me whenever i feel like i'm in a situation where i don't have autonomy and control i'm like oh and when i hear about this sort of food environment we're living in and the big food mafia and the marketing and pinging me left right and center and all the products that are in some of these ultra -processed foods that are making me feel addicted to them that i just it's just triggering my brain in a in a way that i can't seem to control either i go i want to be able to do something about it on an individual level i want to be able to take back control without having to wait for bloody downing street or the white house to change things i love that and what what I try and propose in the book is that you need to make that journey, probably when you start reading the book, you're in this sort of unconscious stage if you don't think of yourself as either a victim or anything, you're just eating your food.

[650] And then midway through the book, I think I do propose to you that you are a victim.

[651] And that's a hard thing for any of us to listen to.

[652] Most of us don't want to be victims.

[653] And I think you have to make the journey from victim to activist pretty quickly.

[654] And you can be an activist in your own life for yourself and you can, if you have resources and money and skills, you can get rid of ultra -processed food.

[655] Lots of people actually can't.

[656] I've just got to be really blunt here.

[657] Like there is an anxiety I had writing this book that for the core audience of readers who can afford books, most of them will be able to buy sourdough from a fancy bakery rather than, you know, the loaf of bread we just looked at.

[658] But for the people who are most affected by the problem, that it simply won't be a choice.

[659] For someone like you, yes, you need to take that kind of emotional reaction and turn it into direct that rage rather than directing it inwards.

[660] It's directing it out to a food system that controls you.

[661] I mean, one of the political narratives we hear is that any kind of regulation is nanny statism.

[662] It's about government overreach.

[663] At the moment we live in a nanny state, the nannying is done by transnational food corporations.

[664] They don't pay any particular tax in this country.

[665] They do employs people, but these are not companies that are part of our sort of culture, and yet they are controlling our food and what we eat.

[666] And I think we need to rest a little bit of control back off those companies.

[667] But that group of people that maybe weren't the majority of people you were speaking to with your book, that don't have the privilege that me and you have to make better choices as it relates to food or to buy the pots and pans and chopping boards or get a shot.

[668] after cook it for us, whatever, what do you say to them?

[669] What do they do?

[670] I mean, this is why I don't give advice, because there is, we are at this moment where we do have to politically treat the companies like the tobacco companies.

[671] Now, at the moment for many people trying to quit ultra -process food will be like trying to quit smoking in the 1960s.

[672] Is it really addictive?

[673] So the, do you want to do a bit on the evidence of addiction?

[674] So the, the, the definition of because people, food addiction has been really scientifically complex for a long time because baked into the notion of addiction is that the only strategy that ever works is abstinence.

[675] You cannot be abstinent from food and so food can't be addictive.

[676] So for a long time we said, well, food is a behavioral addiction where it is the food behavior is not the food itself.

[677] The definition of ultra -processed food allows you to describe the category of substances that are addictive.

[678] And when we go and speak to people who say, I live with addiction to food, and you say, what do you feel addicted to?

[679] It's always ultra -processed product.

[680] It'll be very different.

[681] Some people, it's going to be the diet colors.

[682] Some people, it's biscuits.

[683] Some people, it's pizzas.

[684] But it's always UPS.

[685] The definition of addiction is continued use of a substance, despite knowledge of harms, physical or psychological, and despite repeated attempts to quit.

[686] And you and I will both know people in our own lives who continue to eat this food.

[687] I mean, I was definitely one of these people, despite knowing it was harming me and wanting to stop eating it.

[688] So that's why I think I have two groups of readers.

[689] Some people are just going to want to cut down.

[690] You might be someone who's maybe eating a little bit more than you want and you just want to go, I'm going to maximize my health and I'm just going to have it as a treat on a Friday night.

[691] And that's fine.

[692] It's like it can be like booze or the occasional cigarette.

[693] For some people, that one cigarette, that one glass of wine, but for many, probably 40 % of of people, I don't know about your audience, but across the country, 40 % of people will have a troubled relationship with it.

[694] And for those people, abstinence may be an easier strategy.

[695] So yeah, I think it's addictive when we look at scans.

[696] It's addictive when we do surveys.

[697] It's addictive when we look at the profile of genes and the other surrounding factors that lead to addiction.

[698] It's caused by the same things.

[699] And there's lots of basic science about the speed of consumption and addiction.

[700] So addictive things are normally very quickly consumed shots, crystal meth, tobacco products.

[701] If you chew tobacco, if you have slow release methylphenidate, it's a treatment for ADHD.

[702] It's not addictive.

[703] If you have weak session beer, it's not addictive like tequila shots are.

[704] So the speed of hit seems to be important.

[705] And that may be partly to do with the softness of UPF.

[706] You get a very quick hit of your nutrition.

[707] Is there a link between ultra -process foods and neurodiversity, you know, ADHD, those kinds of things, because there's some emerging evidence about ADHD.

[708] I'm speaking to, there's a working group at the Royal College of psychiatrists who are really interested in the links between binge eating disorders and other eating disorders and an ultra -processed food.

[709] I think we are only at the very beginning of discovering the health effects, but remember from very early on in childhood, a huge number of kids in this country are on a diet of almost pure ultra processed food but that's often in a situation where there is also other sources of trauma of um there'll be other health factors there'll be poor housing um it will go hand in hand with lots of other things so as an adjunct to other other problems i would think there will be a link but teasing it all out's going to be complicated a high u pf diet is linked to more deaths globally than tobacco, high blood pressure, or any other health risk, 22 % of all deaths.

[710] That's the start I got from your book.

[711] And also, increased consumption of UPF, ultra -processed foods, is linked to the following diseases.

[712] All -cause mortality, cardiovascular disease, high blood pressures, fatty liver disease, inflammatory bowel disease, depression, worse blood, fat profile, irritable bowel syndrome, dementia.

[713] And I can't even say that other one.

[714] frailty just being weak and old hmm part five of your book is what am I supposed to do about it and I've kind of answered it I want to make sure I'm really clear in my own life here I can because I have the privilege of doing so I can make better food choices the first part of it is awareness knowing what ultra processed foods are and I believe I've got that definition from you step two is I really need to do an audit of the things that I'm consuming frequently to make sure that I'm at least intentional about my consumption of ultra -processed foods.

[715] And then I can make better choices to bring in more whole foods into my diet.

[716] Because you're right, there's so many things that I'm consuming that I thought were good for me. I mean, I drank bloody orange juice for sunny D for 20 years because I just thought it was great for me. Vitamin D or something, I can't remember.

[717] So sunny.

[718] Yeah, exactly.

[719] And it was marketed at me. Awareness is step one, making more informed choices.

[720] is I guess it's step two for me. And then there's a broader point which is about trying to change the system for others.

[721] Which I can do by having these kind of conversations, I guess.

[722] I love that those steps are coming from you.

[723] I don't have a...

[724] I honestly don't care what people eat.

[725] I like freedom.

[726] I don't like being told what to do.

[727] And so I am not prescriptive about what anyone should eat.

[728] Nowhere in the book, do I say you should, like as a normative statement, you should eat less UPF.

[729] So if you want to, knowing what you know, that's up to you.

[730] I don't think anyone has a duty to be healthy, to generate economic growth.

[731] I just think no one asks to be born.

[732] You're born.

[733] You should be able to live your life as you want.

[734] What I do think is what I want for everyone is that they can, they have agency.

[735] So that they are not subject to constant predatory marketing and they have true choice.

[736] So all the policies that I'm proposing, and I'm part of a big group working on this, are about making real food affordable and available.

[737] So in terms of the hierarchy of what needs to be done for everyone, the number one thing is tackle poverty.

[738] Poverty is a political choice.

[739] There is enormous wealth in this country, and people born into disadvantage should not have a different childhood than people who are born rich.

[740] And it feels kind of almost revolutionary to say that, but it's really obvious to me, like, why, I mean, I can talk about this all day, but health outcomes are so different for people born in poverty, for people who live across the road from my kids.

[741] So that's the number one thing.

[742] The second thing is some very light regulation.

[743] I don't want to tax things.

[744] I don't want to ban things.

[745] We need to appropriately label unhealthy food.

[746] And at the moment, the labels are so confusing is to be unusable.

[747] We need to put in our national nutrition guidance that there is good evidence linking ultra -processed food as a category to all these poor health outcomes.

[748] We should recommend, the government should recommend that people do try and consume less.

[749] Now, there will be a real problem for the government doing that because the government creates a food environment and it's really hard for a government to say, look, on the one hand, don't eat all this, and they go, on the other hand, that is all you can afford to eat.

[750] So that's going to create a real political problem, and that's sort of what we're up against.

[751] The most important, important policy step is to get industry out of the room when it comes to making policy.

[752] So this is, so the, I just spoke at the World of Abistee Federation in New York.

[753] There are UN -aligned, WHO -aligned group.

[754] Outside of the UK, there is no discussion about the role of ultra -process food.

[755] The pandemic obesity is primarily due to this Western industrial diet.

[756] Everyone agrees on this.

[757] Countries like Argentina, a can of cola has three big black hexagons on it, bigger than the logo of the company that makes the cola.

[758] Same with most of the breakfast cereals.

[759] You know, there are warnings in the national guidance.

[760] So globally, people are very, very aware of this.

[761] In the UK, there is real control of the public health narrative by the food and drink industry.

[762] So as an example, all our major charities that influence policy, and a lot of policy comes from charity, they're all paid by companies that make by you.

[763] So if we look at the British Nutrition Foundation, it is majority funded by all the major food companies you can name.

[764] Coca -Cola, Nessla, Cargill, all of them.

[765] Cancer Research UK, Diabetes, UK, the British Dietetic Association.

[766] All of them are funded by companies that make ultra -processed food.

[767] So we need to start treating the companies like the tobacco industry and say, no, no, your money is not good and we won't take it because it influences food policy.

[768] That's kind of the most important step.

[769] And so part of being an activist in this area for me is not taking food industry money myself.

[770] And so that that is a very painful weekly process because if you write a book about food, you get offered, you know, I mean, enormous amounts of money to go and to go and work for the food industry.

[771] How did your food consumption change from the beginning of this book till the end of this book?

[772] were there any particular choices that you have unmade or made because of what you learn in the process of writing this book?

[773] I think resisting addictions, if you live with addiction, is almost impossible.

[774] That's the whole point about addiction.

[775] And what you need to do is to make the journey from being addicted to being disgusted.

[776] And love and disgust, they're anatomically close in the brain, they're neurologically quite related.

[777] And many of a sense, have experienced this falling out of love process where something you're in something or something or someone you're infatuated with that is irresistible you want to spend all your time engaging with suddenly becomes something you really don't want to do and smokers will describe it some people have this experience in human relationships um it can happen that switch can be flicked quite quickly and i think if you're someone who lives with addiction you need to figure out how to flick that switch that at the moment if you're addicted to this food and you're constantly trying to resist it it it will be too much so i i think that that is the kind of the priority if you're living with the addiction is to try and get to disgust and that's what happened to me is the food became you know this thing about the uncanny valley where if if um there's a thing in animations where if animations are very cartoony they're fine but if they become quite human they suddenly start looking weird and there are some films where they get it a bit wrong um uh whether where the cartoon characters are too realistic they they become almost zombie or corpse like so this this uncanny valley that animation goes through where it becomes weird and then when they're ultra human they're fine again the food for me was a bit like that it entered this sort of uncanny valley where it's it's similar to food but it it isn't food and so so now i just don't want any of it but i will eat it to be polite that I brought with me. You know, the pizza, I've got the cocoa pops.

[778] I've got the Coca -Cola here.

[779] Is this food?

[780] I don't think it meets, so food is very poorly defined.

[781] We don't have a working definition of food sort of in law, but I think food is substance that you eat for nourishment.

[782] And it should be about nourishment culturally, socially, personally, psychologically, as well as physically.

[783] And these products are, developed to generate financialized growth for institutional investors, they're not made by people who love you, who want to nourish you.

[784] And so I don't think it meets what I think is a useful cultural definition of food.

[785] I think it's very useful to not think of them as food.

[786] And I don't think a mixture of coloring addictive drugs and phosphoric acid could be called food in any sense of the word.

[787] It doesn't have nutrition.

[788] It only has things that will, we're pretty sure.

[789] sure that almost every ingredient does you harm in some way.

[790] So I don't see how that could be called food.

[791] It's a way of commodifying your ill health for the benefit of a very small number of people.

[792] Are you optimistic?

[793] Oh, that's such a great question.

[794] Like I live with...

[795] And I want the real answer here.

[796] That's a sort of...

[797] Oh, you could ask me, you get a different answer each morning.

[798] So at the moment, here are my sources of optimism.

[799] There is another way of doing this.

[800] I have a friend who runs a not -for -profit drug company.

[801] Works as a normal drug company.

[802] It has a huge quantity of revenue.

[803] Only one person took a pay cut.

[804] That was the CEO.

[805] So he doesn't own it.

[806] Everyone else is paid exactly as if they're at a normal pharmaceutical company.

[807] The purpose of it, and he paid back investors.

[808] It's a really, it would be cool for you to interview him, actually.

[809] He's one of the smartest people I know.

[810] He came from Big Pharma.

[811] And because he's not obliged to institutional investors, he develops drugs for low -income settings.

[812] He also sells them in middle and high -income settings and does really a great job, but the purpose of the company is to reduce healthcare inequalities.

[813] Now, there are lots of people who are working on a similar model that will sit within, you know, a capitalist structure that will pay back investors, but where food needn't becomes so beholden to institutional investors.

[814] So I think there are financial reasons for optimism.

[815] They're economic models.

[816] We can propose corporate structures.

[817] We can incorporate things in different ways that will serve the community in different ways.

[818] So that's one source of optimism.

[819] The second source of optimism is we sort of did it with tobacco.

[820] And the cool, terrible thing about tobacco is we regulated the tobacco industry and got smoking rates right down.

[821] And the growth of equity value of the tobacco companies has continued more or less uninterrupted throughout.

[822] Now, part of that comes from selling cigarettes in other countries.

[823] Some of it comes from the rise of vaping.

[824] But nonetheless, we did manage to get control of tobacco.

[825] So as a public health activist, I have a template.

[826] I know how to do it.

[827] I know how to tackle marketing.

[828] And we have a roadmap.

[829] And we also know that people are furious.

[830] I mean, people are enraged.

[831] For 40 years, we've watched, particularly our children, not just get bigger, but get shorter.

[832] So if you have kids, if you have kids in this country by the age of five, they will be that much shorter than if you had kids in Scandinavia or Bulgaria or the Netherlands.

[833] Okay, at the age of five, that much, nine centimetres.

[834] That is the difference between a British five -year -old and a Bulgarian five -year -old.

[835] And it is all diet.

[836] So it's not just our kids live with obesity.

[837] They are stunted.

[838] Now, you can't stunt a body by nine centimetres at the age of five and not also stunt them intellectually.

[839] So people are furious.

[840] We sort of know this is happening.

[841] We know we can't stop eating this food.

[842] Obesity is all around us.

[843] And so I think there is real, real momentum for people to reclaim.

[844] their foods.

[845] And we do, we do have a lot of amazing food cultures in this country that we can draw on for kind of rich, phenomenal diets.

[846] It might explain why the US is so poor from an education standpoint to some degree.

[847] You know what I mean?

[848] Because they always rank at the very bottom of the education tables.

[849] It's the same in the, it's about the same in the US, the physical stunting.

[850] Really?

[851] And physical stunting, once we, once you get rid of cigarette smoking during pregnancy, which is still far too high, it's really, it's really all due to diet.

[852] So there's all those causes of optimism and yet I also am up against the power any one of these corporations has revenues equivalent to the GDP of a pretty decent sized country like Venezuela or Croatia yeah so and that's any one of the companies do you know this is just such a conspiracy theory that I just popped into my head about my own childhood I'm the youngest of four right and if we just look at the brothers so there's three of us brothers I'm the youngest brother.

[853] And Kevin, my oldest brother, is a monster.

[854] He's like 6 -5 or something.

[855] Even Jason is like 6 -3.

[856] And then I'm short.

[857] And I'm like short in comparison to them.

[858] I'm 6 -1.

[859] But there's so much, there's so much taller than me. And I did, I was thinking about it as you're speaking.

[860] My mother did make home -cooked food.

[861] She was at home during my older brothers and sisters as they were growing up.

[862] So she was cooking in the house the whole time.

[863] African food, lots of whole foods and chickens and vegetables and salads.

[864] A traditional diet.

[865] Like any traditional diet, yeah.

[866] And then she started businesses and stopped coming home.

[867] So I was a scavenger.

[868] And I had like free reign to go to the sweet shop and eat not so good things.

[869] So I was just thinking about, I've always wondered why I'm shorter than them and I'm younger.

[870] But maybe there's correlation.

[871] You're stunted physically and intellectually.

[872] Maybe.

[873] I think you're going to have difficulty selling people.

[874] Yeah.

[875] I mean, it is an intriguing point.

[876] We know about youngest people in Europe that youngest children are about.

[877] I don't know, I don't know that, did it?

[878] They're about five IQ points less smart.

[879] I'm this idiot of the family as well.

[880] My brother's absolute super genius.

[881] They're like mathletes in the UK.

[882] My brother was rewriting the textbook.

[883] He was on the front of the Plymouth Herald because of his bloody, the grades that he got.

[884] I think it was the Plymouth Herald.

[885] It's one of the newspapers.

[886] He was in there.

[887] And Kevin was even smarter.

[888] He was another super genius.

[889] I got kicked out of school.

[890] I was.

[891] It is really intriguing.

[892] I mean, that idea of eating a sort of traditional home -cooked whole food diet versus your probably quite high UPF start.

[893] I mean, the data, you know, you're one case, but we build evidence out of case studies, you know.

[894] I love that idea.

[895] I'm not sure I can really accept you as kind of intellectually, physically stunted, sitting across from you.

[896] No, but academically, they were just so much.

[897] So they still are so far ahead of me. In fact, Jason now works in my company just to help me with everything because he's so smart.

[898] There's a pair of twins I know who's separated at birth, adopted in China separated at birth.

[899] they're quite well now.

[900] I've interviewed them for a podcast.

[901] And one grew up in Norway, one grew up in the States, genetically identical.

[902] And the Norwegian twin is that much taller than the American twin.

[903] So we do see these natural experiments too.

[904] Crazy.

[905] How's your brother getting on?

[906] So he, maybe the biggest effect of the book is he kind of, I stopped a message in the book.

[907] And I would say this because people, people are listening.

[908] And it listens are selfish.

[909] We were like, how do I lose the way?

[910] How do I quit UPF?

[911] I've said that.

[912] But the, the bigger thing is, don't beat your loved ones over the head with this.

[913] So many people are like, I'm going to buy your book for my wife or husband or daughter.

[914] I'm going to tell my kids.

[915] And when we let people go and we stop owning their problems, it gives them agency.

[916] It empowers them.

[917] And then it's up to them to decide.

[918] And if they have the resources and the opportunities, generally they will.

[919] And so a big, a kind of core message to the book is stop nagging your loved ones about their food.

[920] Their food is controlled by forces that are far big.

[921] than you they know what to eat nagging people about their weight only stresses them out and makes it worse so when i it was when i let go properly of what zand eats and stopped really really stopped caring about him and and started to kind of not see him as an extension of myself because when he he would be big in public you know we work together as television presenters and i'd be like god you're embarrassing me like we're trying to talk about health and medicine to kids and look at you and when i let all that go and saw him as like, you know, he's such a wonderful person.

[922] I love him so much.

[923] Who cares about his weight?

[924] That enabled him to sort of engage with it.

[925] Then lots of other things happened.

[926] He's just got married to a public health academic.

[927] He's got resources.

[928] He got a bit older.

[929] I mean, all kinds of things happen.

[930] So much of life is luck.

[931] We can tell these narratives of how someone got from A to B, but he's very fortunate.

[932] And I think celebrating weight loss is just something I'm so anxious about doing but he yeah he a big product of the book was an improvement in my relationship with him because I stopped caring what he ate I find it so interesting why people decide to make changes in their life and it's so different for everybody I've I've wondered and ponded whether sometimes we need a little bit more pain you know I can't forget a conversation I had with a manager or of one of the top music artists in this country that was struggling and this person was a friend of mine the person struggling and I kind of went to him and I was like listen how can I help and he goes you can't he goes I've managed a lot of music artists that have struggled with addictions of various kinds and at some point they'll reach a rock bottom and they'll decide themselves that they need to make a change and it's such a hard thing to accept just to kind of let someone in your view go into free fall in an area of your life you want to to catch them you want to hold them up and support them that that moment of clarity of decision that's when we've all had it a switch suddenly flicks that can never arise as long as someone else is telling it and the the clearest example of this is the washing up that my you know we've got a family and everyone's and sometimes as I'm about to heroically at the end of a meal get up and do all the washing up my wife will say to me could you clear these plates and do the washing up and I've gone from being an empowered person with agency about to heroically do my bit for the family to being someone doing the bidding of someone else and it enrages me and we do it to each other and so just allowing other people to grasp their problems and deal with them or not is you know that's that's it's a really hard journey for a doctor because doctors are all about telling you about yourself and I try and do it less and less it kind of reminds me a little bit of what I was saying earlier about um i don't like it when it feels like i'm being controlled yeah yeah and that's kind of what the food food environment we live in makes me feel like it makes me feel like i don't have a choice you don't and i want to have a choice you don't really have a choice i mean if you have enough money and you're really prepared to get up early in the morning you have some choices but our food food choices is severely curtailed and if you're on a motorway if you're traveling around this country if you just try if you just try and go out on that high street out there and just buy yourself a quick lunch there aren't a lot of choices the pain thing's interesting we need a little bit of pain in our diet we need foods that are bitter and real and chewy and crunchy and make us work for them and take time to prepare and one of the big switches is trying to see food preparation not as a chore but as something that connects you to your ancestors I mean you know we've survived because we come from this long chain of people who just spent hours a day grinding and pulmonary pulverizing and salting and mashing and figuring out how to make food to nourish this.

[933] And it's the thing we should do with other people.

[934] And trying to enjoy food prep is a big change for me. Second ago, I asked you if you're optimistic.

[935] And you gave me...

[936] I dodged it.

[937] You gave me the...

[938] You did a little bit, but you gave me the reasons for being optimistic.

[939] What are the reasons you're pessimistic?

[940] I think because when it came to tobacco control, it took from the certainty that tobacco caused not just lung cancer, but strokes, heart attacks and a whole range of other health outcomes, including early death.

[941] The same list of health outcomes that ultra -processed food causes.

[942] From that knowledge to proper regulation took 50, 60 years.

[943] And because around a significant percentage of women still smoke throughout pregnancy in this country, which is a good benchmark of not succeeding.

[944] They're highly motivated to stop and unable to.

[945] And we, see the rise of vapes.

[946] So it's an arms race.

[947] You know, I'm a virologist by training.

[948] My PhD is in studying how viruses compete with humans.

[949] And in an arms race, you never get ahead for very long.

[950] It's like business.

[951] Business is a great example of an arms race.

[952] You understand arms races better than anyone.

[953] You can't just build your company.

[954] Be like, well, that's, that's done.

[955] Home I go.

[956] Let's watch the money flow.

[957] Someone's always, always trying to overtake you.

[958] And so we're, as a community of activists, what we need to build is a, is a, is a sustainable form of activism that is you build regulation you build on that you keep generating evidence and there are some we have more and more ways of doing it with these sustainable non -for -profit not -for -profit food companies for example as a way of funding activism so are you optimistic i have to be i mean nothing worth achieving will be achieved in our lifetime so this will not be just the work of my lifetime and i'm i'm inheriting this work uh many of us are inheriting this work from generation of people who've been slaving at this since Nestle were indicted for aggressively marketing infant formula in very, very low -income settings and really harming children in low -income countries.

[959] So, you know, that was kind of the first engagement with big food where people were, were angry and we could really point to a problem.

[960] Those activists now, they're my, they're 20, 30 years older than me, and they're sort of handing knowledge to me and a whole bunch of other people across around the world people from the global south people from very diverse communities and so we you know i'm going to hand this to my kids but you know there's a fight and you can be on one side of it i guess chris we have a closing tradition on this podcast where the last guest leaves a question for the next guest not knowing who they're going to leave it for and the question that's been left for you is what will we also has a little brackets and says you regret 10 years about how we brought up our children today.

[961] I can tell you because I already regret it and it's it's not spending the kind of quality time that I've just given you with them that, you know, to spend time with you today, I prepared, I thought about it, I've read your book, I've, you know, I've been listening to the podcast for ages and as a result we've had at least what feels to me like quite a meaningful engagement.

[962] It's really nice.

[963] I leave kind of enriched.

[964] And my kids get these sort of snatches at time.

[965] And you talk about diarizing lunch.

[966] And I know this is the thing you talk about in lots of places.

[967] It's not just giving the crumbs to your family, but it's like giving, investing in your family in the way you do in your work.

[968] And I don't do it because, you know, my wife's pregnant.

[969] I've got two kids, six and three.

[970] And it's just a scramble.

[971] So that's what I will regret and it's great actually being given the opportunity to articulate that and go, okay, if I'm going to regret it, who do I want to be?

[972] And, you know, I love that question.

[973] I'm going to go away and try and force time with them that I'm present.

[974] And often they don't want, they're not interested, but it's just being there listening to them and investing in them regularly in the way that I do with everything else in my life.

[975] Chris, thank you so much because you, I feel like this book, I think it's been in the Sunday Times bestseller chart for like 25, 24 weeks or something mental.

[976] You knocked me off number one.

[977] Oh, listen, I'm just visiting.

[978] You live there.

[979] So I'll be there for another five seconds.

[980] I'm sure you'll be there for many, many more weeks.

[981] And you're starting a really important revolution and conversation around what we eat, a really important one.

[982] And books come along once in a while, once every couple of years.

[983] once in a generation that really meet culture at the exact moment with the exact language, with the exact appreciation of the reader, the nuance, the inclusivity, not taking provocative stances that are so far on the right or so far on the left that they alienate a certain group, they kind of bring everyone in and they appreciate both sides of that nuance and that perspective.

[984] And this is exactly what this book does, perfectly timed.

[985] written perfectly to appeal to both sides of the most tricky narratives.

[986] And that is why it's such a brilliant book.

[987] And that's why everybody needs to read it.

[988] Because as you said, I think before we started recording, it's starting a conversation that we really need to start.

[989] And it's these books that end up changing the world and changing legislation.

[990] So congratulations, first and foremost.

[991] But thank you, secondly, for writing such an important.

[992] book at such an important time i'm really blushing i mean there's there's there's very few people i'd rather hear that from the new it really means a huge amount so thank you
