There is no specific myositis diet that is recommended. In general, it’s important to eat a balanced diet rich in fruits and vegetables. Omega 3 fats, found in oily fish such as sardines and salmon, walnuts and olive oil, are important to include as they have an anti-inflammatory effect on the body.
The Myositis Association says that certain nutritional supplements may be helpful for myositis, although few of these supplements have been extensively studied specifically in this disease. They include potassium (found in bananas), calcium, vitamins A, C, E and D, glucosamine, ginger, turmeric, creatine and coenzyme Q10. Ginger in particular seems to have analgesic, anti-inflammatory and antioxidant effects in some people when used medicinally.
