"Why Paleolithic eating?
Briefly, a Paleolithic diet is the diet we evolved on as a species. Experts estimate the time we spent eating a Paleolithic or “Paleo” diet to be around 2,000,000 years. In contrast, there are the foods that result from agriculture – foods that have only been available to us for the last 10,000 years or so – like grains and dairy products. Finally, we have so called “modern foods” – highly processed foods that have only been available for the last 100 years or less – like packaged foods, white sugar, canned foods, white flour and pasteurized dairy.
Even more recently, “foods” and substances have appeared that are nothing like anything our bodies have ever been exposed to – things like genetically modified foods, pesticides, factory raised meats, irradiated foods, pharmaceuticals and food additives and preservatives.
Our bodies have had only a few generations to adapt to agriculture based foods like grain and dairy. Not surprisingly, gluten and dairy allergies are the most common food allergies in the world. Our bodies have had virtually no time to adapt to modern and highly processed foods. Prominent authors throughout the years have correlated a decline in human health and the proliferation of “modern diseases” like cancer, intestinal disorders, heart disease and diabetes with the increased consumption of agricultural, modern and highly processed foods.
Eating a Paleolithic diet is an effort to provide the body with the foods and nutrients it is most ideally suited for and is adapted to by the power of millions of years of evolution."
