A wonderful personal story: Dr. Joseph Mercola interviews former patient Sarah Allen. Sarah, an athlete, was only in her 20s when she began to notice pain in her body that doctors were not able to diagnose properly for several years. She made an appointment to see Dr. Mercola (practicing in a nearby state) and got a dose of life-changing insight. Listen to this discussion (only 14 minutes of your time). Rheumatoid arthritis is an autoimmune disease that is most often seen in women and involves progressive crippling of the body's joints, although sometimes only in the feet and hands. It can be very painful and disabling. If this autoimmune disease responds so well to dietary changes, imagine what all the others might do!
