In recent years, with people's pursuit of healthy living, more and more people have begun to pay attention to the importance of blood sugar control. In addition to medications** and dietary modifications, some studies have found that drinking tea can also lower blood sugar levels. In these studies, three teas were found to have good hypoglycemic effects, and they were green tea, black tea, and oolong tea.
First of all, green tea is a widely studied tea that is rich in components such as catechins and caffeine. Studies have shown that the catechins in green tea can inhibit the absorption of sugar in the gut, thereby slowing the rise in blood sugar.
Secondly, black tea is a type of tea that has been fermented, and it is rich in components such as tea polyphenols and caffeine. Studies have found that the tea polyphenols in black tea can inhibit the activity of glucosidase in the gut, thereby reducing glucose absorption. In addition, tea polyphenols can also increase the uptake of glucose by muscle and fat cells, promote glucose utilization, and reduce blood sugar levels.
Finally, oolong tea is a semi-fermented tea that is rich in components such as tea polyphenols and caffeine. Studies have found that the tea polyphenols in oolong tea can inhibit the activity of glucosidase in the intestine and reduce the absorption of glucose. In addition, tea polyphenols can also promote the utilization of glucose, increase the uptake of glucose by muscle and fat cells, and reduce blood sugar levels.
In summary, the study found that green tea, black tea and oolong tea all have a good hypoglycemic effect. The ingredients in these teas can inhibit the absorption of sugar in the intestines and promote the secretion and utilization of insulin, thereby lowering blood sugar levels.
However, it is important to note that the caffeine content in tea is higher, which may cause adverse effects such as insomnia and heart palpitations for some people. Therefore, when drinking tea, it should be consumed in moderation and the right tea should be chosen according to the individual's situation.
In addition, the hypoglycemic effect of tea is not singular, it needs to be combined with medications** and dietary modifications to achieve the best results. Therefore, for diabetic patients, in addition to drinking tea, they should also actively cooperate with the doctor's plan, reasonably control their diet, exercise moderately, and maintain good living habits.
