Why would it be “totally retarded”? Our ancestors lived for tens of thousands of years on a similar diet while our own diet changed together with our environment much more radically in the last few thousand or hundred years. Understanding the diet of our ancestors might at least help us understand what we were optimized to eat. That’s not to say we should eat what our ancestors ate, it’s just a nice starting point when you want to go hunt for the optimal food. Evolution obviously influences what we can eat – lactose tolerance (only a few thousand years old) is the best example of that – and evolution clearly had not yet time to react to our radically changing environment (cookies still taste absolutely delicious and not the least bit awful as they should).
