Uric acid forms when the body breaks down purines from some foods and drinks. If there's too much uric acid or if the kidneys don't remove it well, it can build up, causing pain and swelling in the joints.Soybeans and soy products, seafood like shrimp and sardines, and sodas high in fructose can all raise uric acid levels. Excessive intake of these foods and drinks may lead to high uric acid and increase the risk of gout.
