Diabetic patients are often reminded by doctors to control their diet, but many people just one-sidedly understand control as eating less, and our country to rice and noodles as the main food, rice and noodles contain a lot of starch, starch will be converted into sugar in the body, so some diabetic patients choose to eat less or even do not eat staple foods, thinking that this can quickly lower sugar, in fact, this is a very dangerous dietary misunderstanding. The patient, Uncle Chen, lives in Nanjing’s Qixia district and has a five-year history of diabetes. Uncle Chen heard that if the blood sugar is not well controlled will lead to a variety of complications such as eye and foot, and then it will be more difficult to cure, he is a little anxious. In order to control his blood sugar, he chose to eat only a small amount of rice at each meal, and once he drank pumpkin porridge and found that his blood sugar rose very significantly, he no longer dared to drink porridge, and usually ate the most vegetables. But he recently always can not eat, and some want to vomit, which can be Chen Uncle to frightened, rushed to the hospital for examination. Diabetic patients do not eat or eat less staple food is likely to induce reactive hyperglycemia, the body gradually lose weight, and even malnutrition. In addition, eating high protein foods such as milk, eggs and meat instead of eating staple foods can also hurt the stomach. There are some diabetics who only eat a small amount of staple food, but feel hungry will turn to supplement nuts snacks or other high-fat food, the overall calories in the body is not reduced but increased, in fact, this method is even more undesirable, because this is easy to get hyperlipidemia and other complications in the long run, but will aggravate the condition of diabetics. In fact, not only diabetics do not eat, eat less staple food will cause harm to the body, ordinary people who often do not eat staple food, the lack of carbohydrates in the body, will also cause metabolic disorders and insufficient insulin secretion, making insulin glucose-lowering function decreased, resulting in increased blood sugar, triggering diabetes. Because carbohydrates are an important and indispensable component of the human body, they can play a number of roles such as storing calories for the body and regulating fat metabolism, so staple foods must be treated in accordance with scientific and reasonable principles.
