For 2.5 million years, early man foraged and hunted for seafood, meat, vegetables, fruit, nuts, roots and seeds. This period of time before the development of agriculture is known as the Paleolithic era. The Paleo diet is also known as the Stone Age diet, hunter-gathering diet and the caveman diet. No matter what you call our ancestors, some things haven’t changed. Man’s digestive systems have evolved only the slightest amount in the 10,000 years since farming changed our diets. Shortened to Paleo, the modern diet is an approach to nutrition that mimics the early man’s diet for ultimate health. Author:Jimmy Cai
