Strictly grasp the dietary principles, reduce the source of blood uric acid, promote blood uric acid excretion, and limit the intake of purine in food. 1, control protein supply can be taken according to the proportion of body weight. 1kg body weight should be taken 0, 8 ~ 1g of protein, the whole day in 40 ~ 65g, mainly plant protein, animal protein can be used milk, eggs, because milk, eggs have no cell structure, does not contain nuclear protein, can be used within the scope of protein supply, if it is lean meat, chicken and duck meat, etc., should be boiled and eaten in soup. 2.Limit the total calorie intake Because gout patients are mostly accompanied by obesity, research shows that obesity is an important cause of hyperuricemia and gout, so weight control is very important for gout, maintain the ideal body weight, preferably 10% to 15% below the ideal body weight, but weight reduction should be gradual, to reduce 1kg per month is appropriate, otherwise it is easy to lead to ketosis or acute attack of gout, should limit calories in 1500～1800kcal/d is appropriate. 3.Limit fat intake Because fat can reduce the excretion of uric acid, fat intake should be limited to less than 60g per day, and for those who have gout complicated with hyperlipidemia, fat intake should be controlled within 20%-25% of the total, and should be appropriately limited to about 50g/d. Try not to consume fatty meat, fried and deep-fried food. 4.Limit the intake of purine. 600~1000mg of purine is available in the diet of normal people per day, and it should be controlled below 150mg per day for gout patients, and foods with high purine content such as offal of animals, thick meat soup and sea fish are prohibited, and the consumption of meat, fish and shrimp, poultry, spinach, mushroom and soybean products is restricted. You can eat foods with less purine, such as milk and milk products, eggs, rice, noodles, corn, potatoes, and various vegetables such as radish, onion, tomatoes, etc. The special point is to eat less hot pot. Investigation proves: shabu once hot pot than a meal purine intake 10 times higher, or even dozens of times.
