Michigan State University researchers have found that an essential fatty acid called docosahexaenoic acid (DHA) can stop a known trigger of lupus—a systemic autoimmune disease in which the body’s immune system attacks the body’s skin, joints, and organs. It is considered a genetic disease and can be triggered by inhaling crystalline silica toxicants or other environmental factors, such as sun exposure. The researchers discovered that DHA blocked the activation of lupus 96% of the time when it was triggered by crystalline silica. DHA can be found in fatty, cold-water fish and is produced by the algae that fish eat and store in their bodies. Fish oil supplements can also supply this essential fatty acid. Lead researcher Dr. James Pestka adds, “What we do know is this study is a clear indication that eating DHA can prevent this one type of environmental triggering of lupus.” PLOS ONE, August 2016
