![]() So, Katherine, when you argue that the Paleo folks are wrong because humans ate Neolithic foods for many thousands of years without ill effect you are not fully informed of all the facts. In addition to lots of new and different proteins, modern wheat has lots of gluten and tends to cause much higher blood glucose spikes upon consumption by comparison to eikhorn. So modern wheat is very different genetically and chemically from the eikhorn that was eaten by most humans for most of the Neolithic Era. And there was never any human safety testing done on these new wheat strains - nothing like the safety testing required for modern genetically modified crops. Just how big were these changes? Einkorn has 14 chromosomes, while modern wheat has 42 chromosomes. They succeeded in improving yields tremendously, but in so doing they substantially changed the genetics of wheat. Beginning about 50 years ago, scientists began a major breeding program to improve wheat yields using old-fashioned crossbreeding techniques. The wheat that most people ate 10,000 years ago was einkorn, not modern wheat. what? Humans have been eating wheat for 12,000 years you say? What do you mean it has changed? My point is that some of the non-Paleo foods we eat weren't introduced into the diet 12,000 years ago with the Neolithic Revolution, but within the last 100 years, and in the case of most wheat, within the last 50 years. Yes, yes - I know - correlation is not causation. Fats like margarine were not widely consumed until about. Paleo folks argue that Industrial Age fats, such as highly processed vegetable oils, are part of the problem. That said, some non-Paleo foods are part of the older epidemic too, the one beginning 100 years ago. Excessive consumption of these very non-Paleo foods is very likely a major cause of the current obesity epidemic. The Paleo folks argue that about 30 years ago, upon advice from a Congressional sub-committee that was not scientifically validated, Americans replaced saturated fat in their diet with sugar, HFCS, and hydrogenated vegetable oils. So let's appreciate that we are seeing two different obesity surges here, which may share many causes but which may also have some different causes. Since then, they have shot up quite a bit. Obesity rates increased in the early 1900's, but stabilized until the late 70's/early 80's. What we are seeing now is something on a different scale altogether. But the current obesity epidemic really started to take off over the past 30 years. Yes, Americans started getting more fat about 100 years. Katherine, allow me to point out a few factors which I think you are missing. So you'll find the problem in changes within the last hundred years, not the last 10,000. But Americans only started getting fat in large numbers within the last 100 years. No one claims that the modern American diet is healthy. This is more or less exactly my point of disagreement with the Paleo people. ![]() And it certainly doesn't entitle Lustig to say that sugar or fructose or HFCS is toxic. Consumption of 6-12 cans of non-diet coke (depending on the study) a day for weeks at a time, is bad for you.Īll of which proves absolutely nothing about moderate intakes. in the amounts consumed by the fattest 5% of Americans, is bad for your health. I personally think that if you drink so much sugar that you need to buy two seats on the airplane, no money needs to be wasted to verify that your dietary habits are subpar.Ĭonsumption of 25% of fructose or HFCS, ie. Your retort: there are 5% of Americans who do this, so it's not that extreme. ![]() I also think the original one had fructose, HFCS and glucose groups.įrankly, I am getting a bit tired arguing over this, since we seem to be going in circles, with you failing to acknowledge that what they did was extreme. Here the same author fed them 25% fructose, not that I don't think 25% HFCS wouldn't be good enough. ![]() Energy expenditure and substrate utilization were assessed using indirect calorimetry at baseline and during the 10th week of intervention. As part of a parallel arm study, overweight/obese male and female subjects, 40-72 years, consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks. ![]()
