Эндокринолог Роберт Лустиг отказался от «фабричного» йогурта, но продолжает есть мороженое

Top hormone doctor on why he will never eat 'factory' yoghurt - but enjoys ice cream every week despite his strict anti-sugar warnings - Dr Robert Lustig is a Professor of Paediatric Endocrinology - He's become a leading public health authority on the impact of sugar - He appeared on longevity expert Dan Buettner's podcast this week - See more Daily Mail on Google - save us as a Preferred Source A leading endocrinologist has revealed the foods he avoids at all costs to improve his chances of a long and healthy life - and confessed that ice cream will never be one of them. Dr Robert Lustig, renowned for his expertise in explaining the effects of ultra-processed foods, appeared on longevity and 'Blue Zones' expert Dan Buettner's podcast to discuss all things diet, fibre and physiology. The American anti-sugar advocate said he bans three things from his home: candy bars, 'factory' yoghurt and all sugared beverages. 'Anything with a trans fat for sure… like candy bars. Well, you know, unless they're straight chocolate,' Dr Lustig said, adding, 'Coke is a given, too.' '[Also] factory store yogurt. What you do instead is you should buy plain yogurt and then you use your own fruit to mix in with it.' Dr Lustig, 69, has long argued that commercial 'fruit' yoghurt is problematic due to its high sugar content. He previously pointed out that fruit-flavoured yoghurts typically contain 19 to 23 grams of sugar, owing to added sweeteners like high-fructose corn syrup, sucrose, or evaporated cane juice. Despite these strict bans, Dr Lustig admits he regularly enjoys ice cream - happily indulging in one serving of 'real' ice cream a week as a dessert, but never touching frozen yoghurt. The American anti-sugar advocate and Professor of Paediatrics said he bans three things from his home: candy bars, 'factory' yoghurt and all sugared beverages Pictured is Dan Buettner, an American National Geographic Fellow and podcast host who popularised the term 'Blue Zone' 'I bring ice cream in. Oh, I love ice cream for dessert,' he said. Buettner compared this approach to attitudes in long-lived 'Blue Zones,' where indulgent foods are enjoyed occasionally as treats rather than cut out entirely. 'I mean, an easy analogy is cigarettes. If you smoke one cigarette every day for 10 years, anything bad gonna happen to you? Probably not. If you smoke a pack of cigarettes a day, every day for 10 years, now you're gonna die,' Dr Lustig observed. 'It's a dose issue and it's a chronicity issue. So there's a certain dose below which you can manage your exposure. And ultra-processed food is the same thing.' While Dr Lustig classifies standard commercial ice cream as an ultra-processed, high-sugar treat that contributes to disease, he acknowledges that real dairy fat may contain protective compounds not found in alternatives like frozen yoghurt. 'Frozen yogurt is a scam,' Dr Lustig said previously. 'First of all, ice cream has dairy fat C15:0, which is protective against heart disease. Frozen yogurt doesn't. Ice cream and frozen yogurt both have emulsifiers to make the product smooth, but emulsifiers cause gut inflammation. 'Lastly, the amount of sugar in both products is disastrous and dwarf the lactic acid, which might be beneficial. 'What you do instead is you buy the plain yogurt and then you use your own fruit to mix in with it,' he advised, adding that 'frozen yoghurt is a scam' 'Bottom line, neither are "good for you", so enjoy whichever one you like better, as long as you make it a rare treat, not a common "diet staple".' The power of fibre Dr Lustig also spoke about the importance of boosting fibre intake - something most people fail to get enough of. 'There's no fibre in virtually anything that's ultra-processed,' he noted. 'And if you ask any dietitian, they'll tell you fibre is important but they won't be able to tell you why.' He explained it simply: the fibre is not for you, but for your microbiome. 'It is the food for your bacteria. When you eat food with fiber, you're actually servicing your microbiome. Your microbiome gets healthier and your microbiome becomes more diverse, which is always good,' he said. 'If you don't feed your bacteria, your bacteria will feed on you. They want to survive. They will eat the mucin layer off the surface of your intestinal epithelial cells that's protective from all the junk in your intestines. 'Fibre is your all-purpose cleanser - not of your GI tract, but of your whole body because the GI tract is happy.' Dr Lustig added that when fibre is consumed, bacteria break it down into short-chain fatty acids, the main one being butyrate, which is anti-inflammatory. 'That's what you need in order to not have irritable bowel syndrome, not have inflammatory bowel disease and most importantly, not have Alzheimer's disease,' he said.
