Fructose: fructose is metabolized by the liver can produce a large number of uric acid precursors, resulting in increased uric acid production, indirectly increasing the risk of gout stone. 4. Beer: Alcohol inhibits the discharge of uric acid and promotes purine metabolism to generate uric acid, thus causing gout stone.
