It is safe to say that people with diabetes can drink black tea, this is because black tea is rich in flavonoids that scavenge free radicals and lead to a lower incidence of myocardial infarction. Studies have also proved that black tea is beneficial for diabetics because it stimulates insulin secretion and lowers postprandial blood sugar spikes. In addition, it benefits women with diabetes to prevent osteoporosis. Diabetic patients can choose some beneficial teas to drink according to their conditions, such as green tea, wolfberry tea, black tea, cornhusk tea, American ginseng tea, lotus heart tea, honeysuckle tea and so on.
