First, guava
Guava has some role in regulating blood sugar. The effect of pomegranate leaves is much better than the fresh fruit. Animal experiments show that the effective component of pomegranate leaves is flavonoid glycosides. In fact, this substance has no significant influence on the level of insulin. As a result, we presume that it does not by improving the function of the pancreas islet to regulate the blood sugar, but by promoting the utilization of glucose of the tissues around the body. Therefore, it is beneficial for the diabetes patients to use pomegranate leaves to make tea and drink it for a long term.

Second, bitter melon
Some hospital use bitter melon powder to make tablets for the adjuvant treatment of diabetes. After the treatment, the blood glucose of the diabetes patients drops significantly. In the daily life, the diabetes patients can often and appropriately eat some bitter melon, which may bring unexpected results to them. But they should also pay attention that bitter melon may bring some side effects, such as abdominal pain, diarrhea and other gastrointestinal reactions, so they should not eat too much of it.

Third, eel
Yellow eel contains some substances which can restore and regulate the normal physiological function of blood sugar. Experimental results show that yellow eel has a significant effect of lowering the blood sugar level, which is similar to insulin. As a result, it is beneficial for the diabetic patients to often eat eel. Generally speaking, if the patients continue to eat 100 to 150 grams of eel every daily, after 3 to 4 weeks, their blood sugar as well as the urine sugar will be greatly decreased.

Fourth, tremella
Tremella is rich in dietary fiber, and low in heat. It contains a large number of tremella polysaccharides, which have a significant effect on the hypoglycemic activity of the insulin. Animal experiments show that tremella polysaccharides can affect the activity of insulin. It can extend the action time of insulin in the body from 3 to 4 hours to 8 to 12 hours, so as to make it function much better.

Fifth, mulberry, mulberry leaves
Many reports point out that mulberry and mulberry leaves can be used as an adjuvant treatment of diabetes. They contain mulberry leaf polysaccharide, which has the effect of regulating blood sugar. As a result, diabetes patients can try to make tea by mulberry leaves, which is very helpful.

In addition, other foods such as tea, lotus leaves, corn silk, carp, loach fish, green beans, etc, also have certain effect of regulating the level of blood sugar.
