I would strongly advise you to have your patient begin a gluten-free diet. It's not recognized as a "cure" by medical science, but there is anecdotal evidence to suggest that it can work for MS, Lupus, and other autoimmune disorders. I was in really bad shape until I discovered that I had Celiac in 2005, after a lifetime of undiagnosed disease. Your patient has nothing to lose by trying this diet, and possibly may get his health back.

Below: Dangerous Grains turns the U.S. Food Guide Pyramid upside down by exposing the myriad health risks posed by gluten grains (wheat, rye, barley, spelt, kamut, and triticale). The authors, leading experts in the field of food allergies, and celiac disease, present compelling evidence that our grain-centered diet is to blame for a host of chronic illnesses. Largely misunderstood and frequently misdiagnosed, these disorders can be prevented and reversed by the useful program outlined in this important new book.
