Starch, Milk and Alcohol: How Have Our Genes Adapted? | Giles Yeo | TEDxCambridgeUniversity

Humans are like cockroaches, we adapt when we have to, including to changing nutritional demands post agriculture.
Giles Yeo has 20 years’ experience studying the genetics of obesity & brain control of food intake. He got his PhD from the University of Cambridge in 1998 and his currently focuses on the influence of genes on our feeding behaviour & body-weight. Giles is also a broadcaster and author, presenting science documentaries for the BBC’s ‘Horizon’ & ‘Trust Me I’m A Doctor’. His first book ‘Gene Eating: The Science of Obesity & the Truth About Diets’ was published in December 2018.

    Lactose intolerance is not present when drinking raw, whole milk. The heat in the process of pasteurizing destroys the enzyme lactase, leaving only lactose, the substance that is at the root of lactose intolerance.

    It intrigues me that this is why we use alcohol for hand sanitisers. A chemical that kills germs pretty much has to be a poison. But as non-arboreal primates we're _more_ resistant to alcohol than most things, so we can use it to poison viruses, etc. relatively safely. Whereas methanol (for instance) would also kill germs but be too likely to poison us.

    As dig person I recommend you to put your dog on diet where you mainly give him/her meat, especially organ meat, and bones with morrow etc. and just observe how it's hair and health improves. Yes dog adopted to starchy food but it's not optimal for them, and prices of some of this stomach fillers are just ridiculous. This adaptation simply gave dogs better chance of survival. Similarly bears who are omnivores and can survive on any food, but if have a chance they are mainly predatory creatures. Humans are the same. We are omnivores and opportunistic beings, and that's why we survived. No way human adopted to modern wheat which consist like twice the amount of chromosomes compare to it's original form. This is causing wheat to have way more types of proteins which our body can't digest. I lean towards theory that this is not gluten which is causing gut issues but rather these new proteins made by modern wheat, if you can even call it a wheat. Not even gonna mention all the flavour enhancers, fillers, preservatives and Round up.

    An adaptation might give you easy access to energy, and give you a reproductive advantage, but still reduce your total life span. The ability to handle starch seems to be directly related to someone getting diabetes in later life through the hormonal effects of insulin spikes the starch induces. With regard to the quality of life, it is certainly worth investigating what the effects are of where you get your energy from, adapted or not to starch, milk and/or alcohol.

    When we look at the chemicals, additives and preservatives, and antibiotics we can see that the problem isn't food itself but what is Done to it. I refer to the book Metabolical by Dr Lustig. Consider how these diseases are exploding now but they were rare up until the 1900's.

    @Peter Rabbit - Pianist-Composer ♫ You can argue that dietary fibre is an important auxiliary component which supports the digestive tract. However the human body has no enzymes to break it down and metabolise it. The fact that foods high in fibre contain a certain amount of net carbs is true but irrelevant for the fact that their sugars and starches are not essential for the human body. They are more like a byproduct, energy storage for plants. No human *needs* to eat sucrose, glucose, fructose, starch (which is broken down to glucose) etc, hence all the carbohydrates which *can* be metabolised. Those are non-essential. They have no vital structural functions in body cells unlike amino and fatty acids from proteins and fats. The human body can store only about 2000 kcal of glycogen which can be converted to glucose by the liver. However this is only a short-term energy storage and has no other vital function. A human body can function perfectly without any stored glycogen, hence no glucose (or derivative) intake is required. Btw, the only cells which do require glucose are red blood cells. However the relatively small amount they require can be generated by the liver through gluconeogenesis from protein intake. All other cells can run on ketones including the brain.

    @Peter Rabbit - Pianist-Composer ♫ The mono and oligosaccharides are essential for plants only, not for humans. The human body can generate glucose and other sugars from proteins and fats. You are putting the cart before the horse. Sugars and starches could be completely removed from the cellulose part of the plant and it would be enough for the intestinal microbiome to do its job fermenting the fibre, making essential fatty acids for instance. There is no vital requirement for the human body to absorb sugars and starches, as little as there is a vital requirement to absorb alcohol.

    Before humans became meat eaters, they were gatherers of wild fruit and berries, before the stone age of weapons to kill game. So if you're looking at the earliest eating habits, they would be plant based rather than animal based. That would have been our first adaptation. Meat based paleo diet doesn't go back far enough

    He says mil drinking isn’t bad for you but that’s a misnomer . Having the ability to digest milk is to be able to eat more calories and utilizing them but biology is worried about reproductive success And that’s it. So even having lactase does not mean it cannot increase your risk of other diseases correlated with dairy intake when you’re 50-90 years old

    Sir, it is already good visible numerous signs of pre-diabetes with mild obesity on your body, from which I suppose that perhaps you haven't adapted so efficiently to digesting starches and other such things, to eating those "food-like creations" that didn't exist in the Paleolithic... Also, not all trends in paleo abstain from fatty meats. (Neither do I, in fact...! I specifically follow the Carnivore diet, which I think is a subset of paleo! Oh, and I eat meat and offal raw...) The modern paleo trends specifically recommend the consumption of FATTY meat, because to maximize the benefits of nutritional ketosis...
