A Paleolithic diet consumed by contemporary humans consists of items of foods selected from the types or groups of foods consumed by ancestral humans who lived during the Paleolithic age, or Old (paleo) Stone (lithic) age, predominantly in Sub-Sahara Africa, beginning approximately 2 million years ago (2 mya)[1] and ending with the introduction of agriculture approximately 10,000 years ago (10 kya).[2] [3] The term applies also to the diet consumed by those Paleolithic human ancestors.

Interest in the Paleolithic diet by nutritional scientists stems from the argument that humans adapted their biology (physiology and metabolism) through evolutionary processes operating for millions of years before adopting a dramatically different diet following the recent inventions of agriculture and husbandry, and the industrial and fast-food revolutions, creating a mismatch between evolved biology and diet, a mismatch deleterious to health.[2]

[before the present] making it the earliest archaeological site of its size and state of preservation currently known in Africa. As the westernmost Oldowan site known in Africa, Senga 5A significantly expands our knowledge of the geographic range of early tool using hominids.

- Abstract: A detailed literature survey reviews and discusses nutritional aspects of the diets of historical paleolithic societies and their nutritional adequacy in light of current nutritional knowledge. Topics include the evaluation of food consumption habits, ranging from hominids (about 24 to 5 million years ago), through the appearance of archaic homo sapiens (about 400,000 years ago), to the twentieth century; dietary habits of recent hunter-gatherer societies with respect to meat and vegetable consumption; the probable nutrient intakes of paleolithic humans for specific nutrients (energy; fat and fatty acids; cholesterol; sodium and potassium; calcium; ascorbic acid; fiber; and other nutrients), and evidence for nutrient shortages; and a comparison of the late paleolithic diet to the current U.S. diet and the current U.S. dietary recommendations.
