Gout, a painful form of arthritis, occurs when high levels of uric acid in the blood cause crystals to form and accumulate around a joint.

Uric acid is produced when the body breaks down a chemical called purine. Purine occurs naturally in your body, but it's also found in certain foods. Uric acid is eliminated from the body in urine.

A gout diet may help decrease uric acid levels in the blood. While a gout diet is not a cure, it may lower the risk of recurring painful gout attacks and slow the progression of joint damage. Medication also is needed to manage pain and to lower levels of uric acid.
