I have a friend who has managed to control her RA by means of diet for 20 years. When she was initially diagnosed, the doctor wanted to put her on medication that had the rare side-effect of blindness. She didn't want to take any chances with her vision, so she sought out a naturopath who put her on an elimination diet. Within a few days she had improved.
Currently her biggest problem is with iritis, plus her diet has become increasingly constricted over the years. (However, she has a fabulous figure because of it!) I am going to forward the website you posted to her in case it might help her. Thanks!
