Reducing uric acid production in the body and promoting uric acid excretion are the basic dietary principles for gout: 1. Low purine diet: limit daily purine intake to less than 150mg (about 15%-25% of normal dietary purine intake). 2. 2. Obese people should reduce their body weight to the ideal weight or suitable state, and generally reduce their daily calorie intake by 10%-15% compared with normal. 3.Protein: 0.8-1.0g/kg, mainly vegetable protein, milk and eggs do not contain nuclear protein, can be the main source of protein. 4.Fat: should be limited, about 25% of the total calories, the total amount is less than 50mg. 5.Increase fluid intake: 2500-3000ml per day to facilitate uric acid excretion. 6.Supplement sufficient vitamin C and B complex vitamins. 7.Low salt. 8.Prohibit smoking and alcohol. Specific methods: 1. Limit the intake of purine. Normal people consume 600-1000 mg of purine daily from the diet. Since purine is the raw material for synthesizing uric acid, patients with gout should control the intake of purine for a long time, and foods with purine content <75 mg% are suitable for the chronic period. The third type of food with high purine content is forbidden, and the second type of food with medium purine content is used in a limited amount. 2.Limit caloric energy. People with gout and obesity should limit caloric energy and reduce body weight. The caloric energy supply should generally be 10-15% lower than normal people, and the weight should preferably be 10-15% lower than the standard weight. Since carbohydrates can prevent tissue catabolism and produce ketone bodies, and have a tendency to increase uric acid elimination, they should be the main source of calories. Fructose can increase the production and excretion of uric acid, so the proportion of fructose in raw carbohydrate should not be too large. Restriction of calories should be carried out gradually to avoid excessive decomposition of body fat, causing or aggravating the acute attack of gout. 3, moderate protein and fat supply. Protein should be limited to no more than 80 grams per day, choosing milk, cheese, eggs, cereals and vegetables as the main source of protein. Try not to use meat, poultry, fish and other foods containing high purine, if you must use, the number should be small, and meat, poultry should first be boiled and discarded soup, and then used. Fat can inhibit the excretion of uric acid salt, so fat intake should be appropriately limited and should be controlled at about 50 grams per day. 4, pay attention to the supply of B vitamins and vitamin C. It is appropriate to eat more vegetables, fruits and other alkaline food, vegetables can supply about 1000 grams a day, fruits can be consumed 4-5 times a day; alkaline environment can improve the solubility of urate, conducive to the excretion of uric acid; vegetables and fruits are rich in vitamin C, can promote the dissolution and removal of uric acid salts in the tissue. 5, gout is easy to combine with hypertension and hyperlipidemia, should limit sodium intake, daily salt intake of 2-5 grams. 6, drink more water or eat food containing water, the daily liquid intake should be more than 2000-3000 ml, in order to increase the amount of urine, to promote uric acid excretion; if there is renal insufficiency, liquid intake should be properly adjusted. 7, forbidden to eat strong spices and spicy condiments. Coffee, tea and cocoa can be used in moderation. Wine can cause the accumulation of lactic acid in the body, lactic acid has a competitive inhibitory effect on uric acid excretion, so it is better not to drink alcohol.
