I had asked about the DIET with my rheumy. His comment was that placebo's were effective 50% of the time. He meant to say that the diet will work for some and not for others. I don't believe there are any long term studies for a diet protocol? If not, there really should be. For me, since I am diabetic, I am already on a low carb aka low starch diet. I tell you that I saw no difference from before and after.
This is not from a rheumy who is anti-Ebringer. In fact, he admits Dr. Ebringer will be proven that he was correct given time.
