Strict control of diet is a prerequisite and the most important part of the treatment of diabetes. Doctors in clinical practice found that patients often because of poor dietary control and drugs can not play a proper curative effect. The principles of diet control are as follows: 1. Break the misconception that “taking more glucose-lowering drugs can make you eat more”. 2. 2, eat less and more meals. Not only to ensure the supply of heat and nutrition, but also to avoid the post-prandial blood sugar peak. 3, carbohydrate food should be eaten according to the rules, not less and not more, to eat evenly (carbohydrate refers to grain, vegetables, milk, fruit, soy products, hard fruit food sugar). 4, eat sweet snacks and salty snacks are no different, both will cause blood sugar to rise. 5. The amount of “diabetic food” eaten should be equal to the amount of ordinary food eaten. “Diabetic food” refers to food made with high dietary fiber, such as: buckwheat, oats. Although these foods take longer to digest and absorb, but eventually they will become glucose. 6, the so-called “sugar-free food” is essentially not added to the food, certain foods are sweeteners instead of sucrose, still can not just 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 lentils, green beans, fava beans, kidney beans, peas, their main ingredients are also starch, so they should also be counted as the amount of staple foods. 9, eat side dishes should also be moderate. 10, can not be filled with peanut rice, melon seeds, walnuts, almonds, pine nuts and other hard fruit food. 11, eat more food containing dietary fiber. 12.Eat less salt. 13, eat less cholesterol-containing food. 14.About eating fruits. 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 two meals when blood sugar is low. If the fruit is eaten after it is equal to an extra meal, blood sugar will be high immediately. Bananas are high in starch and should be counted as the amount of staple food. 15.Sweetener will not be converted into glucose, will not affect the change of blood sugar, can not be used as a self-help food for hypoglycemia. 16.Diabetics should never restrict drinking water.
