Paleolithic diet

The paleolithic diet (also called the paleo diet, caveman diet or stone-age diet) is based mainly on foods presumed to be available to paleolithic humans. There is wide variability in the way the diet is interpreted. It includes vegetables, fruits, nuts, roots, meat, and organ meats while excluding foods such as dairy products, grains, sugar, legumes, processed oils, salt, and alcohol or coffee. The diet is based on avoiding not just modern processed foods, but rather the foods that humans began eating after the Neolithic Revolution. The ideas behind the diet can be traced to Walter Voegtlin, and have been popularized more recently in the best-selling books of Loren Cordain.
