I have read that caffeine is a no-no with RSD. And so is added sugar (other than what's in your fruit naturally). Fresh is good. I actually had put myself for three months on a Dr. Lorraine Day diet after listening to her tell her story about how diet helped cure her cancer. I figured, if diet can help the body rid itself of cancer, why should it not aid in curing other things--and she was into barley greens along with lots of fresh squeezed carrot juice, no red meat. Also, her diet extended into life, including 1/2 hour outdoors every day, trying to do something nice for someone else every day--this is all I remember right now. I did end up losing 9 pounds from eating so healthy, but the progress was so slow it was hard to tell if it was helping. None of it hurt though--I didn't get worse from it. Every little bit helps...would love to know the results of the study.
