Gout is a metabolic disease caused by purine metabolism disorder, which leads to the increase of urate content in body fluids, and then crystallizes around cartilage, synovial bursa and joints, causing joint inflammation.

Purine in human body comes partly from the decomposition of cells and partly from the metabolism of food in the body. Therefore, taking diet therapy should also start from two aspects, one is to strengthen the excretion of endogenous uric acid, and the other is to reduce the production of exogenous uric acid.

1. Control the intake of purine and protein: Generally, normal people can consume 6 ~ 1mg of purine per day in their diet, while gout patients should control the intake of purine below 15mg per day. At the same time, the intake of protein should be controlled, and the daily weight per kilogram should be limited to .8 ~ 1g. Because protein has a special dynamic function, it can increase the production of endogenous uric acid. Foods rich in purine, such as animal viscera, brain marrow, wild birds and sardine meat, should be fasted; Lean meat, fish, fungi, beans and peanuts of poultry and wild birds should be used less. However, in order to ensure the supply of high-quality protein, you can eat more milk and eggs with low purine content. Fish and meat with high purine content can also be soaked in water and boiled before being eaten in soup, which can reduce purine in food by about 5%.

2. control the total heat energy: obesity is a predisposing factor of gout, so all obese gout patients should adopt a low-heat diet to gradually lose weight. But don't be too hasty to avoid hunger ketosis and induce acute gout attack. Gout patients should eat less carbohydrates, especially refined sugar, because carbohydrates can enhance the body's sensitivity to purine.

3. Increase the supply of vitamin B1, vitamin C and water: vitamin B1 and vitamin C can promote the dissolution of urate accumulated in tissues. Water is not only the dissolving agent of urate, but also can promote its excretion. Therefore, it should contain enough vitamin B1 and vitamin C in the diet. If the heart and kidney function permit, besides the normal diet, 1 ~ 2 ml of drinks can be added every day, which is not only beneficial to the excretion of uric acid, but also can prevent the formation of urinary calculi.

4. increase the intake of alkaline food: uric acid is easy to deposit in acidic environment, while alkaline environment is beneficial to the dissolution of uric acid, thus increasing its discharge. Therefore, we should eat more alkaline foods such as fruits and vegetables in the diet, reduce the intake of acidic foods such as fish and livestock meat, and keep the urine alkaline, thus increasing the excretion of uric acid.

5. limit the intake of salt and irritating food: salt can keep water in the body and prevent uric acid from being discharged. Therefore, the intake of salt should not exceed 5 grams per day. Alcohol, strong tea, coffee, vinegar, garlic and pepper can increase the sensitivity of the body, so they should be used less or banned.

6. Simple dietotherapy: For obese gout patients, a "fruit and vegetable diet day" can be arranged regularly every week, that is, the normal diet is prohibited within the specified day, and only 1,5 grams of apples or 1,5 grams of cucumbers and 1-2 eggs are used instead, and they are eaten for 5-6 times. You can also use vegetables with less purine, add a small amount of cooked vegetable oil and salt to make cold dishes, and eat them in 5 ~ 6 times. Such a diet is beneficial to the metabolism of purine and the relief and recovery of gout.
