Paleo diets are all the rage, but as Rob Dunn argues, the term obscures as much as it reveals. The key question is which ancestors we should be emulating:
A paleo diet is an arbitrary thing. Which paleo diet should we eat? The one from twelve thousand years ago? A hundred thousand years ago? Forty million years ago? I would argue that, IF we want to return to our ancestral diets, 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.
Early discussion of wheat allergies and my own diagnosis here. Update from a reader:
Don't forget that along with the paleo diet one needs to follow the paleo exercise program. Our ancestors were up hunter-gathering all day, not sitting in front of a computer or TV.
