Although eating certain foods and drinking alcohol may trigger a rise in the level of uric acid in the body, these habits may not by themselves cause gout.

Gout is more common in men over the age of 45, but it can occur in anyone at any age. Factors ranging from a family history of gout, to having other health issues such as high blood pressure, diabetes or kidney disease, can increase risk for developing gout.

Active research is ongoing in a variety of fields related to gout and hyperuricemia. Scientists have found that high animal protein slightly increased the risk for gout.
