The paleolithic diet (abbreviated paleo 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.
The paleo diet centers on commonly available modern foods consisting mainly of fish, grass-fed pasture raised meats (beef, pork, lamb, poultry, and game meat, if you can get it), fish, seafood, eggs, vegetables, fruit, fungi, roots, and nuts, seeds, and healthful oils (olive, coconut, avocado, macadamia, walnut and flaxseed). The paleo diet excludes grains, legumes, dairy products, potatoes, refined salt, refined sugar, and processed oils.
The researcher, Loren Cordain PhD at Colorado State University, has shown that it is entirely doable to consume a nutritionally balanced diet from commonly available contemporary foods. Despite the elimination of two major food groups (dairy and cereals), the trace nutrient density of the diet remains exceptionally high. Moreover, the diet maintains numerous nutritional characteristics that have been demonstrated to reduce the risk of a variety of chronic diseases.
