The
paleolithic diet (also called the
paleo diet,
caveman diet or
stone-age diet) is a diet based mainly on foods similar to those supposedly available to early humans in
prehistoric times. It is based on what proponents claim
paleolithic humans likely would have eaten, such lean meat, fish, fruit, vegetables, root vegetables, eggs, and nuts. It excludes foods such as
dairy products, grains, sugar, legumes, processed oils, salt, and alcohol or coffee. Scientists acknowledge that the diets of our predecessors went through a fundamental change with the addition of meat.
Evolutionary biology can have influence on food and health, but nutrition is very complex.
