4Leaf is a simple concept aimed at promoting a near optimal diet for all of humankind. For the definition of an optimal diet, we use this powerful conclusion by T. Colin Campbell, PhD, the Cornell professor who led the most comprehensive study of human nutrition ever conducted:

“The closer we get to eating a diet of whole, plant-based foods, the better off we will be.”

Obviously, the closest one can get to that diet is by deriving all calories from those healthiest of foods (whole plants)–so we developed a program that sets the top bar at 80% (getting at least 80% of one’s weekly calories from whole plants). We call that top level the 4Leaf level. The 3Leaf level is over 60%, 2Leaf is over 40%, and 1Leaf is over 20%. Note that the average American is currently getting far less than 10% of their weekly calories from whole plants.

What we eat is the one factor that can prevent, reverse, and even cure most of the diseases that plague the western world like diabetes, obesity, and heart disease.

This site was created to help people everywhere establish the healthiest permanent eating regimen possible. Our 4Leaf Survey will help you determine where on our scale you are eating today. A 4Leaf diet-style will do wonders for your own health, and if enough humans join us, some incredible environmental improvements will be generated, as well.

Are you ready to do something great for yourself and for the planet?
