Dietary modifications in the form of conservative therapeutics play an active role on lupus activity. Specific dietary factors including caloric intake, fatty acids, vitamin A, D, and E, and herbal medicine are beneficial in regulation of lupus. Vitamin D deficiency has been linked to several autoimmune diseases like lupus, rheumatoid arthritis, and inflammatory bowel disease. Vitamin D plays an active role in calcium balance and has immunomodulatory effects on T lymphocytes (active cells of the immune system). Lifestyle changes and dietary adjustments are suggested as an adjuvant therapy for lupus.
