Yes, and we are enjoying the longest lifespan ever. We didn't evolve to automatically stent our arteries, but when folks with heart disease do just that they live longer.

"Eat what we evolved to eat" is a romantically appealing argument but it is not logically sound. It's better than, "if you want your brains to grow properly, eat brains; after all, they have exactly the nutritionaly makeup you need," but it's still flawed in proving that a diet that was available to early humans was optimal for longevity.

I admit, however, that a logically flawed argument sometimes proves to give the right answer after all, but for my money (and life!) I'm going with Western science and nutrition for the most part.
