Talk about health food – the kinds of fish loaded with omega-3 fatty acids are good for everything from heart disease to depression, including arthritis, according to researchers at Harvard Medical School, Cambridge, Mass.

Not only can omega-3s significantly reduce joint pain and shorten the duration of morning stiffness, but studies, such as those reported in the American Journal of Clinical Nutrition, show that increased levels of omega-3 fatty acids also have enabled people taking nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce their dosage or discontinue use.

Adding about two 3-ounce servings of seafood to your menu each week is a good way to increase your levels of omega-3s. The highest levels of omega-3 can be found in salmon, trout, mackerel, tuna, sardines and herring, which are all cold-water, fatty fish. Inflammation in your body should decrease with the addition of omega-3s to your diet.

Many studies on inflammation and fish use fish oil supplements to increase intake of omega-3s. If you’re averse to fish and are considering fish-oil supplements, check with your doctor first for proper dosage, especially if you are taking blood thinners.
