You Never Know

When you're going to run into something really cool in a comments section of a really cool blog.
This from one of DeLong's:

Vegetarianism is unhealthy.
Had we evolved to be vegetarians, we would have huge stomachs, massive jaws, and have pointed head because a crest on the skull is required to anchor the massive jaw muscles required to be a vegetarian. We would, on the whole, look more like gorillas than humans. And function like them too.
The last all vegetable eating human precursors were A. robustus and Ramidus (if I am recalling correctly). They did not survive. Their brains could not enlarge because they had too little long chain fatty acids and protein. They had to eat all day, had large stomachs, small brains, and little mobility, rather like the gorilla, a vegetarian primate.
A baby raised as a vegetarian will have an underdeveloped nervous system and a small and poorly functioning brain.
A vegetarian diet forces excess reliance on high carbohydrate, high glycemic foods. There is no there way to obtain adequate calories but to eat this way. Otherwise, you have to eat too frequently and too much bulky vegetables to be active. So, you are almost forced or induced to be inactive.
Countries like India where vegetarianism is widely practiced are undergoing an explosion of Type 2 diabetes. Of course, there is a linkage because they consume large amounts of rice and other simple, high glycemic foods, destroying their metabolism and sliding into insulin resistance, accelerated aging, and diabetes.
Ultimately, I ponder over how gene expression is altered in veganism and its diet variants. Remember, the model is DNA makes RNA makes protein. That is all the genes do; they make proteins. How is their expression altered when there is either too little protein in the diet or when certain proteins cannot be made given the nutrition. Virtually all the messengers in the body are proteins. So are all the catalysts. I could go on, but you get the idea. Don’t do it.

I have no idea if this guy's even close to accurate, but it was fun to read.
