Gout attacks are related to the level of uric acid in the blood, so gout patients with poorly controlled blood uric acid should eat less purine-rich foods, but purine-rich foods are not a contraindication for gout patients. It is necessary to control the diet scientifically according to the specific blood uric acid level in order to reduce gout attacks. For patients whose blood uric acid level is much higher than normal, they should try to avoid foods with high purine content, such as soybeans, shiitake mushrooms, beef, mutton, lobster, crab, etc., and focus on foods with low purine content, such as rice, wheat, fresh milk, eggs, etc. They can occasionally eat foods with moderate purine content, such as tofu, dried beans, grass carp, peanuts, etc. For patients with mildly elevated blood uric acid level, they should eat less food with high purine content, moderate food with moderate purine content and more food with less purine content. For elderly gout patients, they should pay more attention to the control of blood uric acid and balanced diet, and try to match a reasonable diet with foods with low purine content.
