According to a new study, black tea can help in controlling diabetes. The research has been published in the Journal of Food Science.
For arriving at the conclusion, researchers from the Tianjin Key Laboratory in China studied the polysaccharide levels of green, oolong and black teas and whether they could be used to treat diabetes.
Polysaccharides can be useful to people with diabetes because they can help retard absorption of glucose. The researchers found that of the three teas, the polysaccharides in black tea had the most glucose-inhibiting properties.
The black tea polysaccharides also showed the highest foraging effect on free radicals, which are involved in the onset of diseases such as cancer and rheumatoid arthritis.
“Many efforts have been made to search for effective glucose inhibitors from natural materials,” says lead researcher Haixia Chen.
“There is a potential for exploitation of black tea polysaccharide in managing diabetes,” the expert added.
