If i was diagnosed positive for ra, can i delay or prevent it ?

Possibly: You may want to get tested for gluten sensitivity and leaky gut. I know it sounds like an unlikely casue for ra, which is an autoimmune disease, but there is a growing body of evidence being published suggesting there is a correlation between sensitivity to a protein found in wheat, rye and barley (gluten), intestinal permeability (leaky gut) and autoimmune diseases like ra.
