The Paleo Diet is based primarily on how our ancestors ate about 500 generations ago before the modern agricultural revolution. These foods, based on 229 of the previous hunter gatherer societies, which consist mainly of lean meats, seafood, fresh fruits and vegetables, are high in the essential nutrients such as vitamins, minerals, photochemicals, fiber, omega 3’s, antioxidants, and more.
These foods are also low in the glycemic index, which describes the effects on blood glucose levels, which is a large indicator of weight loss & weight gain. These paleo foods are also low in trans fat, refined sugars, salt, and high glycemic carbs. The diet is meant to eliminate the bad and increase the good in foods that are available to us to promote overall health (limit diseases).
According to Dr. Loren Cordain (Father of Paleo Nutrition), “The Paleo Diet encourages dieters to replace dairy and grain products with fresh fruits and vegetables — foods that are more nutritious than whole grains or dairy products.” A study done at the Department of Health and Exercise Science, Colorado State University, has found that Paleolithic nutrition provides all the vitamins and minerals we need, except for Vitamin D (which we mainly get through exposure to sun), even with the elimination of two major food groups.
Basically, the paleo diet is based upon how we ate before our current diets of processed foods, high fructose corn syrups, hormone induced massive growth in plants and animals, and other genetically modified food behaviors. It is going back to the source that mother nature has intended for humans to consume in order to live. Paleo is about going back to the environment where disease was less and obesity was not a factor.
