There are many claims about the power of food for easing arthritis pain. From eating a cherry a day for relieving aches, to eliminating dairy to prevent arthritis from worsening, its hard to know what dietary advice to follow.While there is no diet that will cure your arthritis-whether its osteoarthritis (OA) or rheumatoid arthritis (RA)-a simple way to start feeling better with food is to think fresh and colorful, according to Roxanne B. Sukol, MD, Cleveland Clinics Wellness Enterprise medical director.When thinking about aging and inflammation, I think of rust inside us. Foods that increase the rust are anything that is high in omega-6s, which is all processed food products, says Dr. Sukol. To decrease the rust and inflammation, keep it simple. The more fresh fruits and vegetables and the richer and deeper the color, the better.
