The main point of the PB is that this adaptability is extremely minimal and takes many many generations. As long as there are enough calories for an individual to make it to reproductive age there is absolutely no selective force. This is the problem that we have been facing since the paleolithic age; agriculture provided us with lots of easy calories allowing us to survive and spread around the planet. It's the lack of our proper diet that we evolved on that has stopped modern humans from truly being able to thrive.

Quite so. I'm just saying that some people have adaptations to harmful things and while a paleolithic diet is a good choice for anyone, there will likely be certain individual variations that one should take into account. East Asians have quite a good adaptation to high amounts of starch and French people generally have a good adaptation to lactose and casein. Perhaps some people would do better with more vegetables, perhaps some people would benefit from adding a few generally good neolithic foods like butter, kefir, tempeh, etc. Various herbs and spices are demonstrably beneficial and I do think that supplementation has its merits and will continue to improve as science does.

If any of William Wolcott's metabolic typing stuff makes sense, it is the acid/alkaline balance. Eskimos for example would be very naturally alkaline and should avoid too many alkaline foods to avoid over-alkalinity. But look at the Kitvans. They will more naturally be acidic and would do well to avoid too much meat.
I don't think that too much deviance from the general primal blueprint is a good idea, but I doubt that everyone would be best off physiologically as a carnivore.
Nobody is best off as a vegan, that's for damn sure.
I agree 100% with this post.

Now that many of them are using a "western" diet is that the illness that affect the entire civilized world are getting around by record numbers.
Esselstyn is promoting lots of vegetables. We eat lots of vegetables as well. He would ditch the meat for beans/soy; which are high in cabohydrates. Meat ; eggs have zero glycemic index. Both diets are similar. His patients; eat less donuts; and more veggies; so they lose weight. We all agree veggies are good. Then its the old debate between more fat or more carbs. I think Mark Sisson has the better science. Esselstyn is using the "fat clogs your pipes" paradigm. But arteries are not sewer pipes. There is a complex inflammatory mechanism occurring; caused by glycemic load; sugars; carbs. Not fats.

Here's the deal,
Everyone is different and does well on an individualized diet; however, as humans there are specific nutrients that we need to thrive and be as healthy as possible. A number of those minerals/vitamins are mainly contained in animal products (Vitamin B12, Vitamin A, copper, zinc, chronium, safe complete proteins, vitamin K from milk products, gelatin from bone broths, etc).
It seems to be much harder to get sufficient amount of the above when one is not eating animal products, and thus much harder to be optimally healthy. That being said there are many other important vitamins and minerals contained in plants foods, so indeed an omnivore, real food, diet is ideal I think.
I will not even go into the whole saturated fat and cholesterol cause heart disease comment, because that is far dead (ie. proven incorrect long ago)
