It's my opinion that eating LESS is far more important that what you eat. Please note that I don't necessarily practice what I preach in this matter.
With a lower intake, even with less healthy food, the body has a better chance at processing the matter.
With an aesthetic diet (raw or otherwise), if you overeat, your body will still have to work hard to process all the matter, overwhelming the system. Granted, there should be less toxins to deal with, but I believe that we are equipped to deal with a "normal" amount of toxins.
