Scott Adams of Dilbert fame writes on his blog that science's biggest fail of all time is 'everything about diet and fitness':
I used to think fatty food made you fat. Now it seems the opposite is true. Eating lots of peanuts, avocados, and cheese, for example, probably decreases your appetite and keeps you thin. I used to think vitamins had been thoroughly studied for their health trade-offs. They haven’t. The reason you take one multivitamin pill a day is marketing, not science. I used to think the U.S. food pyramid was good science. In the past it was not, and I assume it is not now. I used to think drinking one glass of alcohol a day is good for health, but now I think that idea is probably just a correlation found in studies.
According to Adams, the direct problem of science is that it has been collectively steering an entire generation toward obesity, diabetes, and coronary problems. But the indirect problem might be worse: It is hard to trust science because it has a credibility issue that it earned. "I think science has earned its lack of credibility with the public. If you kick me in the balls for 20-years, how do you expect me to close my eyes and trust you?"
And thats the problem, that being extremely evolutionarily recent.
Compare to something like the changes due to fire/cooking which are just kinda getting completely figured out / solved in the teeth and intestine lengths and ratios, and thats orders of magnitude longer ago than soy cultivation. Its pretty recent. Apparently the wisdom tooth thing still hasn't been evolutionarily figured out WRT cooked food jaw shape.
And thats before getting into the legendary dietary differences between humans from different geographic areas, most of humanity genetically can't deal very well with dairy products, and others have highly varying responses to ethanol metabolism.
One interesting point of concern is soy allergy is one of the top ten or so most common food allergies, something like 6 to 8 percent of the population has an antibody response at one point or another, one level or another. Here's an interesting article:
Calling something food when you know it'll make maybe 7% of the population sick to one level or another is kind of weird. Its right up there with Olestra. Obviously its regional, anyone in asia who gets sick from soy died of starvation millennia ago, the survivors can handle it. Kind of like all my ancestors figured out the whole lactose digestion thing or starved before having kids, so unlike them I can handle dairy much better than they can.
