Beef, pork, lamb and goat contain high amounts of purines and may trigger gout attacks. Purines are natural substances found in all foods that are usually broken down into uric acid during digestion
Organ meat such as liver, kidneys, brains and heart contains higher amounts of purines. Patients who over eat these types of meat are at risk for gout attacks. Patients with kidney problems also have a higher risk of gout attacks because they have problems with eliminating uric excess acid. MayoClinic advises patients at risk for gout attacks to eat moderate amounts of protein from plant sources such as soy and tofu and to limit intake of meat to 4 to 6 oz.
