Diets that lower inflammation
There has been considerable interest in the influence of dietary factors on many different autoimmune diseases, including lupus. Much of this interest has focused on omega-3 fatty acids because of their potential effects on inflammation. Animal fats are a source of omega-6 fatty acids. Fish, flaxseed and canola oils, and green, leafy vegetables are sources of omega-3 fatty acids. The relative amount of omega-6 and omega-3 fatty acids in the diet affects the types of prostaglandins and other compounds the body produces that influence the inflammatory response. The omega-3 fatty acids in particular result in the production of more anti-inflammatory compounds.
There has been one large study of dietary factors in relation to lupus disease activity. In this study of 216 lupus patients in Japan conducted by Yuko Minami, MD, there was no association found between intake of total fat, type of fat, or omega-3 fatty acids and subsequent disease activity over a four-year period. However, higher intakes of antioxidants (for example, vitamins C and E) were associated with decreased disease activity.
Thus, although currently available studies suggest that diets high in antioxidants--and possibly omega-3 fatty acids--may help lupus symptoms, this is still an unanswered question. The role of antioxidants in disease progression and activity is a relatively under-studied area of research.
It is important to discuss any major change in your diet, especially changes that include use of dietary supplements, with your doctor. There may be potential interactions with prescribed medications or other aspects of your care that are important for your physician to evaluate.
