Okay, I see the point. It is quite obvious with the pants - "pants keep me warm and protect from poison ivy, therefore they are good for me". With food, not so obvious. "Chips and pizza with coke are tasty and make me happy, therefore they are good for me". Doesn't work the same way. In fact, I can't easily think of any artificial food that is definitely good for humans.
Thats not what I was saying at all. My point is that just because we are adapted to a certain diet doesn't make that diet optimal. Much modern food is undeniably unhealthy but starving yourself because our ancestors were hungry too is scientifically questionable. Nutrition is complicated but there is no reason we can't do better than our ancestors.
