The exact cause of autoimmunity is unclear, but research suggests a mixture of genetic and environmental factors are to blame. Of these various environmental factors, experts point to diet as a likely key component.
With autoimmune diseases, the immune system mistakenly perceives the body's own tissues as foreign invaders and attacks them. There are more than 80 such diseases, including multiple sclerosis, Hashimoto's thyroiditis, systemic lupus, rheumatoid arthritis, Crohn's disease, type 1 diabetes and inflammatory bowel disease (IBD).
