Not only to ensure the supply of heat and nutrition, but also to avoid the postprandial blood sugar peak. 3, carbohydrate food should be eaten according to the rules, not less and not more, to eat evenly (carbohydrates refer to grain, vegetables, milk, fruit, soy products, hard fruit food sugar). 4, eat sweet snacks and salty snacks are no different, will cause blood glucose to rise. 5. The amount of “diabetic food” eaten should be equal to the amount of ordinary food eaten. “Diabetic food” refers to the food made with high dietary fiber, such as: buckwheat, oats. Although these foods take longer to digest and absorb, but eventually it will become glucose. 6, the so-called “sugar-free food” is essentially not added to the food, some foods are sweeteners instead of sucrose, still can not eat. 7, starch as the main component of the vegetables should be counted in the amount of staple foods. These vegetables are potatoes, white potatoes, lotus root, yam, rhizome, taro, lily, water chestnuts, cicada, etc. 8, in addition to soy beans, such as red beans, green beans, fava beans, kidney beans, peas, their main component is also starch, so also be counted as the amount of staple foods. 9, eat side dishes should also be moderate. 10, can not use peanuts, melon seeds, walnuts, almonds, pine nuts and other hard fruit food filling. 11, eat more food containing dietary fiber. 12.Eat less salt. 13, eat less cholesterol-containing food. 14, on the issue of eating fruit. Patients with better blood sugar control can eat fruits with low sugar content, such as apples, pears, oranges, oranges, strawberries, etc., but the amount should not be too much. The time to eat fruit should be in between the two meals when blood sugar is low. If you eat fruit after the meal is the same as an additional meal, blood sugar will be immediately high up. In addition, after eating watermelon, sugar is absorbed quickly, so try not to eat. Bananas have a high starch content and should be counted as a staple food. 15, sweeteners will not be converted into glucose, will not affect the changes in blood sugar, can not be used as a self-help food for hypoglycemia. 16, diabetic patients should not limit the water.
