Paleo Studies

As with any scientific theory, research needs to be conducted to test and validate that idea. Since its inception in the early 2000s, studies have been conducted exploring the health benefits of The Paleo Diet; that body of research grows more rapidly every year. This page lists all the research addressing The Paleo Diet to date.
