I see a man who has, like many people, seen improvements from one way of eating, then (as everything in life is always changing) found that that way of eating was no longer serving him, and so he adapted. Kind of like I was with the Paleo diet (which by the way served me very well for a number of years, but I ended up lacking white rice and a few other foods I had eliminated).
I have met and interviewed David Wolfe on a number of occasions, each and every time it was a brilliant experience... Based on some of the comments on the interviews I have posted it appears that some people are less impressed by his ways, products and information, each to their own, I like the guy and love the information and foods he is sharing....
