The ‘Paleo’ Diet
A current new trend, also popularly referred to as the caveman diet, Stone Age diet and hunter gatherer diet, is a modern nutritional plan based on the presumed ancient diet of wild plants and animals that various hominid species habitually consumed during the Paleolithic era — a period of about 2.5 million years which ended around 10,000 years ago with the development of agriculture and grain-based diets.
Centered on commonly available modern foods, the contemporary "Paleolithic diet" consists mainly of fish, grass-fed pasture raised meats, eggs, vegetables, fruit, fungi, roots, and nuts, and excludes grains, legumes, dairy products, potatoes, refined salt, refined sugar, and processed oils. Fundamentally, the Paleolithic diet rejects an excessive consumption of industrial era processed foods for whole natural vitamin rich foods. On the Paleolithic diet, practitioners are permitted to drink mainly water, and some advocates recommend tea as a healthy drink, but alcoholic and fermented beverages are restricted from the diet.
