The Paleo Diet is based on the idea that our hunter-gatherer ancestors were genetically well adapted to the foods that they could find in nature. They may have lived short lives due to many dangers but evidence shows that they were generally very physically healthy. The introduction of agriculture and technology have allowed humans access to many more types of foods like grains and processed sugars. Some of which we may not be genetically adapted to digest without adverse health effects.
Today’s Paleo Diet is a modern adaptation of what our ancestors ate. Here are the basics of what you should eat on the Paleo diet: variety of wild and pastured meats, fish, eggs, vegetables, fruits, nuts, and seeds. The foods to avoid: grains, legumes, most dairy, soy and processed sugars. There is more to it and if you are interested, check out the many Paleo resources on the web.
