Strictly speaking, there is no natural food that is capable of lowering blood sugar. It only affects blood sugar at different levels due to the different sugar and calorie content. Only glucose-lowering drugs have a real hypoglycemic effect. At present, there are two main categories of food that claim to have a hypoglycemic effect, one is a variety of health food, such as a variety of hypoglycemic cookies, etc. This category is actually not hypoglycemic, but rather weak glycemic because it contains more fiber. But there are also some illegal addition of some hypoglycemic drugs, and to achieve the so-called hypoglycemic effect. The other category is a variety of meal replacements, this can be chosen in the case of good economic conditions, but also is not directly lowering sugar, but the nutrients inside the proportion, the impact on blood sugar is relatively small, if eaten more, will also cause blood sugar rise. And some other vegetables, like various green leafy vegetables, onions, bitter gourd, fungus, etc., which are relatively low in sugar and calorie content themselves, have a small impact on blood sugar and can be preferred. Therefore, after the occurrence of diabetes, you should avoid looking for sugar-lowering foods, but should carry out regular dietary management under the guidance of a doctor, only then can you achieve a better effect of sugar reduction.
