Paleo concept

Humans evolved on a diet very different from today's eating habits. To be healthier, leaner, stronger and fitter, we must re-think our diet and remove some of the food groups we consider basic.

Except

Paleo fans tend to overlook the fact that hunter-gatherers were not models of pristine health. Palaeolithic humans suffered from parasites, infectious diseases, and even atherosclerosis (hardening of the arteries).
