Human Ancestors Were Nearly All Vegetarians | Guest Blog, Scientific American Blog Network
Paleolithic diets have become all the rage, but are they getting our ancestral diet all wrong?
Which paleo diet should we eat? The one from twelve thousand years ago? A hundred thousand years ago? Forty million years ago? IF we want to return to our ancestral diets, the ones we ate when most of the features of our guts were evolving, we might reasonably eat what our ancestors spent the most time eating during the largest periods of the evolution of our guts. If that is the case, we need to be eating fruits, nuts, and vegetables—especially fungus-covered tropical leaves.
But the truth is, for most of the last twenty million years of the evolution of our bodies, through most of the big changes, we were eating fruit, nuts, leaves and the occasional bit of insect, frog, bird or mouse. And so while some of us might do well with milk, some might do better than others with starch and some might do better or worse with alcohol, we all have the basic machinery to get fruity or nutty without trouble.
