In the face of attractive sugar-free black sesame moon cakes, diabetics should pay special attention not to be superstitious about sugar-free moon cakes, because some sugar-free moon cakes are not sugar-free, strictly speaking, starch and other ingredients are also "sugar", so even if you eat sugar-free moon cakes, you should pay attention to the right amount. In addition, because some sugar-free black sesame moon cakes contain high oil content and cholesterol content, it is suggested that citizens should not eat more than 1/4 pieces of sugar-free black sesame moon cakes each time, and at the same time, they should subtract the corresponding staple food after eating the moon cakes. In the choice of eating time, patients who need insulin injection should choose to eat moon cakes before injection. Diabetic patients should not blindly control their diet during festivals, thinking that eating less can control their blood sugar. If protein in the body is not enough to meet the needs of normal metabolism, it is certainly not enough to meet the needs of insulin secretion. In this case, diabetes cannot be alleviated at all. Therefore, dietary intake must be carried out under the arrangement of doctors.
