Recently, according to the US "Health Day" website, Dr. Hilpa Bupaserazu, a public health doctor, and his colleagues combed and analyzed the coffee consumption of 124000 subjects, including 7300 diabetics. A four-year follow-up found that people drank an average of 1.69 cups of coffee a day. On this basis, drinking an extra cup of coffee a day reduces the risk of diabetes by 11%; reducing coffee intake increases the risk of disease by 17%; 3 cups of coffee a day has the best "sugar prevention" effect, reducing the risk of disease by about 37%; but it is best not to drink more than 5 cups a day.

The exact mechanism by which coffee reduces the risk of diabetes needs to be further studied, the researchers said. However, it should be noted that coffee is only one of the many factors that affect the risk of diabetes, and drinking too much can also lead to rapid heartbeat, insomnia and other problems.
