Hyperuricemia (HUA) is defined as a fasting blood uric acid level higher than 420 μmol/L in men and 360 μmol/L in women on two non-same days under a normal purine diet, which is called hyperuricemia. Hyperuricemia is one of the complications of kidney lesions, and hyperuricemia can also cause and aggravate kidney damage. In addition to uric acid crystalline deposits leading to small renal arteries and chronic interstitial inflammation, many epidemiological surveys and animal studies have shown that uric acid can directly cause microangiopathy in the small glomerular inlet arteries, leading to chronic kidney disease and causing a vicious cycle. In addition to taking medications as prescribed by the doctor, improving lifestyle is the fundamental way to keep hyperuricemia under control. What should be improved from? 1. Healthy diet: The general rule of purine content in food is: offal > meat, fish > dried beans, nuts > leafy vegetables > cereals > starchy, fruits. If you have gout, hyperuricemia, cardiovascular metabolic risk factors and middle-aged and elderly people, your diet should be based on low purine food, strictly control the intake of meat, seafood and animal offal, and reduce the intake of Class B food in medium amount. Category A (0-15mg) Cereals other than category B, vegetables other than category B, sugar, fruit juice, milk, eggs, cheese, tea, coffee, chocolate, dried fruits, red wine Category B (50-150mg) Meat, prosciutto, gravy, fish, cereals, bread, coarse grains, shellfish, cereals, bread, green beans, peas, beans, soybeans, tofu Category C (150-1000mg) 1000mg) animal offal, thick gravy, anchovies, sardines, beer. In general, the following points should be controlled: ① Control the total caloric intake: eat less carbohydrates. In addition, also eat less cane sugar, honey, vegetables in the young lentils, green fava beans, fresh peas contain high purine, but also to limit consumption. ②Systematic protein intake: choose more milk, cheese, skim milk powder and eggs, try not to eat meat, poultry, fish, soy products although the protein content is high but gout patients should not eat, because the purine content is high, for example: soybeans, tofu, dried beans, etc. are prohibited. ③ Limit purine intake: animal food has more purine content. Avoid or ban foods high in purines such as animal offal, shrimp and crab, thick broth, edible mushrooms, seaweed, anchovies, sardines, clams, beans and beer. ④ Eat more alkaline foods: such as vegetables, potatoes, fruits (plums, lemons), etc. Watermelon and winter melon are not only alkaline foods, but also more beneficial to gout patients. ⑤ Reduce fat intake: eat less fat, because fat can reduce uric acid excretion. ⑥Limit salt intake: The amount of salt eaten should be limited to 2 grams to 5 grams per day. ⑦ Avoid drinking alcohol: alcohol has the effect of inhibiting uric acid excretion, and a small amount of long-term alcohol consumption can also stimulate increased purine synthesis. ⑧ Less chili and other spices: chili, curry, pepper, pepper, mustard, ginger and other spices should be eaten as little as possible. 2, drink more water, quit smoking and alcohol: daily water intake to ensure urine volume in more than 1500ml, quit smoking, ban beer and white wine, red wine in moderation. Usually should drink more plain water, mineral water, and fruit juice, etc. 3, adhere to the exercise, weight control: daily moderate intensity exercise for more than 30 minutes. Obese people should lose weight, weight loss is important for hyperuricemia. The patient’s diet should be controlled at about 80-90% of the normal diet, and do not fast and over-starve.
