Diet therapy is the basic treatment for diabetic patients. Diabetic patients should have a balanced diet, keep a variety of foods and choose foods with low sugar content in order to ensure the nutrition and blood sugar stability of diabetic patients. Diabetic patients are not advocated to eat thin rice, because thin rice has more water and is easier to digest and absorb than rice and steamed buns, and the longer thin rice is boiled, the more sticky it is, the better it is, the easier it is to absorb, and the faster the blood sugar rises after meals. This is because the longer the food is processed, the higher the temperature, the higher the glycemic index. When thin rice is boiled for a long time, the starch in rice is partially decomposed into short-chain carbohydrates, such as dextrin, which is easier to digest and absorb than starch, and is quickly decomposed into glucose in the body, which is absorbed by the body and directly raises blood sugar concentration, i.e. raises postprandial blood sugar. As thin rice leads to fast emptying of the stomach, easy to have hunger, is not conducive to dietary control, is not conducive to the prevention of diabetic complications. Therefore, diabetics try not to eat thin rice, if you want to eat it should not boil too bad, breakfast fasting not to drink, can stay after lunch meal, but lunch and dinner to reduce the amount of staple food accordingly.
