The new role of banana sap may help anti diabetes
Nov 21, 2018

According to a study published in the Czech Journal of Food Science, the juice extracted from banana stems contains anti-diabetic ingredients. Diabetes is a metabolic syndrome in which blood sugar is above normal. The causes include a lack of insulin production or a decrease in insulin sensitivity. Insulin is a hormone that keeps blood sugar levels normal, and its inability to function will cause a rapid rise in blood sugar.


It has been observed in previous studies that phytochemicals in bananas have potential for the treatment of diabetes, such as by inhibiting carbohydrate digestive enzymes and glucose adsorption, promoting antioxidant activity, and the like. However, to date, these phytochemicals have not been researched and developed into botanical drugs or other health products with anti-diabetic activity. In addition, not all bananas are the same. This means that these phytochemicals and their corresponding biological activities may not be present in all bananas. These differences may be related to the variety or growing environment.

In this study, the researchers tested the effects of anti-diabetic compounds extracted from natural growth varieties from Vietnam and banana stem juice grown in Czech greenhouses on diabetes, and analyzed their metabolite profiles. There are variations in the compounds in both samples. It has been observed that of the 17 compounds screened, only 9 of the banana stem juices grown in the greenhouse, and 12 of the banana stem juices grown in Vietnam.


In addition, the researchers determined anti-diabetic activity based on their inhibition of alpha-amylase and alpha-glucosidase and their ability to inhibit cells from becoming fat cells, indicating that both sources of stem juice versus alpha-glucose The degree of inhibition by glucosidase was similar, and the growth of bananas grown in Vietnam was slightly higher; both were dose-dependent. At the same time, the two have no significant inhibitory effect on α-amylase. However, neither sample prevented the cells from transforming into fat cells.


For the results of the study, the researchers believe that banana stems, which are often considered waste, contain phytochemicals with anti-diabetic potential. Although environmental conditions affect the presence of phytochemicals, the level of inhibition of alpha-amylase remains unchanged regardless of where the banana is grown. This suggests that bananas can be used as a natural functional ingredient in the treatment of diabetes, and in the future may help people reduce the need for harmful anti-diabetic drugs.
