Gout is a metabolic disorder linked to high levels of uric acid in the blood. Uric acid, a by-product of various body processes, is also formed after eating certain foods. The body rids itself of uric acid through the urine. But some people produce too much uric acid-or can't dispose of it fast enough-and levels build up. Often, the excess uric acid is converted into needle-shaped crystals that settle in and around joints and other tissues, triggering inflammation and the excruciating pain associated with gout.

It's uncertain what precipitates a gout attack, though some factors may put you at risk. A quarter of those who suffer from gout have a family history of the illness, and three-quarters have high triglyceride levels. Men who gain a lot of weight between ages 20 and 40 are particularly vulnerable. Excessive alcohol intake (including "binge" drinking), high blood pressure, kidney disease, exposure to lead, crash diets, and certain medications (including antibiotics, diuretics, and cancer chemotherapy drugs) may also play a role. For a few people, eating foods high in chemicals called purines (such as liver or anchovies) can cause flare-ups.

Supplements and herbs

Cherries, an old folk remedy for gout, are rich in flavonoids and often effective at lowering uric acid levels. Cherry Fruit Extract is available at Healthy Choices; cherry or blueberry juice (a half cup a day) also works well. In incremental doses, vitamin C helps uric acid to free itself from the tissues and be excreted in the urine. (High initial doses may release so much uric acid that a kidney stone develops.) Nettle can be helpful internally and externally: Capsules clear out excess uric acid, and topical nettle tea compresses may relieve inflamed joints.
