The paleo diet and Primal Blueprint way of eating (a.k.a. Primal) are both based on similar evolutionary science. The story goes something like this. Our modern Western diet bears little resemblance to the eating habits of early humans throughout several 100,000 years of evolutionary history. Instead, since the Agricultural Revolution some mere 10,000 years ago, we’ve adopted a nutritional regime to which our physiology is poorly adapted. When the basics of our diet return to the patterns of our pre-agricultural ancestors, we work with, instead of against, our physiology. More simply: eat as our ancestors ate, and we’ll be healthier for it.
