Early diabetic nephropathy patients with normal kidney function have different diets from those with kidney failure: staple foods should account for 50-60% of the total calories in the diet, advocating coarse rice, whole wheat pasta, mixed grains (buckwheat noodles, oat noodles, corn, potatoes, etc.), which not only do not cause a sharp increase in blood sugar, but also have a high dietary fiber content and a strong sense of satiety, which is conducive to controlling food intake. Avoid eating monosaccharides (glucose, fructose), disaccharides (sucrose, lactose) and their products, including candy, snacks, cookies, drinks, ice cream, chocolate, etc. These foods can make blood sugar rise rapidly and obviously. The protein content generally does not exceed 15% of the total calories, and adults should have 0.8~1.2g/day/Kg body weight. Pure milk, lean meat, fish and shrimp, poultry and eggs should be preferred, followed by beans and various soy products, and the former should be guaranteed at least 1/3. Limit fat intake, that is, the daily fat quantity should not exceed 30% of the total daily calories, with unsaturated fatty acids (tea seed oil, olive oil, flax oil, fish oil, etc.) as the main ingredients, and the oil that is solid at room temperature (cow, pig and mutton oil) contains more saturated fatty acids and should be eaten sparingly, and try not to consume animal Viscera. Eat more vegetables and choose fruits. Fruits have good taste and can supplement a lot of vitamins, fruit acids and minerals, so when blood sugar control is stable (2 hours after meal blood sugar is below 10mmol/L, glycosylated hemoglobin is below 7.5%), you can choose fruits. Among them, watermelon, apple, pear and orange have relatively low sugar content and can be eaten with confidence, while banana, red date, lychee, persimmon and red fruit have relatively high sugar content and should be reduced. It is best to eat fruit between two meals to do extra meals with, not only to not too high blood sugar, but also to prevent the occurrence of hypoglycemia. Drink more water and limit alcohol consumption. Limit salt to 6g/day, and if complicated with hypertension should be <5g/day. Don't restrict drinking water, moderate amount of water facilitates the discharge of metabolites in the body and the dilution of blood sugar. However, limit drinking alcohol, which is very high in calories and increases the burden on the liver, and is prone to hypoglycemia on an empty stomach, try not to drink white wine and avoid drinking alcohol on an empty stomach. Adhere to regular and quantitative meals, and promote small and frequent meals. A small number of meals can ensure adequate nutrition and reduce the burden on the pancreas, which is conducive to good blood sugar control.
