There are many misconceptions about diabetes treatment circulating in the society, and as a result, it has increased the occurrence of tragedies of diabetes causing disability and death. The following situations are common cognitive misconceptions of diabetic patients, and we hope to draw the high attention of diabetic patients. 1. Only controlling staple food, not controlling total calories. If the intake of staple food is too low, the body will break down protein and produce heat from fat, which will further cause the three major metabolic disorders and even produce ketoacidosis. If only staple food is controlled and total calories are not controlled, blood sugar control will not be ideal. 2, the faster you eat, the better. Diabetic patients should not eat too fast, eat too fast, should not produce a sense of satiety, resulting in excessive food intake. On the contrary, the meal time is long, so that the glucose concentration will not be too concentrated, can make the postprandial blood glucose rise calmly. 3.Eat only vegetarian and not non-vegetarian. Advocate balanced meals. Animal food nutrition is irreplaceable by plant food. The protein content is high, it is high-quality protein, and the ratio of amino acids contained is suitable for human needs. 4.Do not eat in order not to take medicine. Not eating in order not to take medicine. When diabetic patients have certain reasons and cannot eat, they should stop taking their hypoglycemic drugs in order to avoid causing hypoglycemia. In order not to eat or take less medication and thus not to eat or eat less is wrong and will cause malnutrition in the long run. 5, in order to urinate less, thus drinking less water. The polyuria is not caused by more water in the body, but by high blood sugar. Drink less water blood concentration is prone to hyperosmolarity, “imported substances” in the only water is not limited, but to encourage more water. 6, sugar-free food can be eaten at will. Sugar-free food does not contain simple sugar or sucrose, food still contains carbohydrates as other foods, must be arranged in the total calorie share of the day a certain amount of heat, can not just eat. 7, a food can reduce sugar. In general, the vast majority of food contains energy, and as long as it contains energy, the intake of the body will raise blood sugar, only some food because of low energy density, or contains nutrients such as dietary fiber, the speed of raising blood sugar is not fast, not strong, but the overall trend is to make blood sugar rise, and will not lower blood sugar. People often say that the bitter melon, pumpkin, etc., are so. 8, suffering from diabetes will never be able to enjoy food. Many people with diabetes are labeled as “diabetic” or “impaired glucose tolerance” and the first thing they are told is that they need to control their diet. It seems that diabetes means living an almost ascetic life, “no meat, no grains, no fruit, no ……”. The total amount of control, equal exchange.
