Drink coffee healthily every day and stay away from diabetes

Finnish scientists published an article in the Journal of the American Medical Association that the more coffee middle-aged people drink every day, the lower their risk of developing type 2 diabetes.

As coffee is one of the most popular beverages in the world, and Westerners don't like it without coffee, the long-term effect of drinking coffee on health has always been a matter of great concern to scholars all over the world. A study published in the Lancet two years ago showed that the more coffee you consume, the less likely you are to develop type 2 diabetes. But it has been widely believed that caffeine in coffee combines with sugar to make cells less tolerant to insulin, thus increasing the likelihood of diabetes. Therefore, the result of this research has been very controversial.

Dr. Jaakko Tuomilehto and his colleagues from the National Institute of Public Health under the Ministry of Epidemiology and Health Promotion of Finland have conducted large-scale studies on the relationship between coffee and type 2 diabetes since 1982, and obtained the same results, thus proving that drinking coffee is beneficial to reducing diabetes.

The researchers surveyed more than 14000 volunteers aged 35 to 64 in Finland for 12 years. During the study period, a total of 381 new diabetics were born. The researchers also analyzed factors such as gender, age, smoking, drinking, education, economy, daily exercise, health index, and drinking crude or filtered coffee. The results showed that the more coffee you drank, the lower your risk of developing diabetes, and vice versa.

In addition, the researchers found that people who drank crude coffee were more than twice as likely to develop diabetes as those who drank filtered coffee. It is worth mentioning that the researchers also analyzed the likelihood of diabetes among a small number of people who drank tea. The results showed that the more tea they drank, the lower their risk of developing diabetes. However, due to the small number of sampling samples, there is no significant statistical significance.

Although the study dispels concerns that caffeine and sugar in coffee may lead to diabetes, scientists have yet to figure out how caffeine can prevent diabetes. The researchers speculate that chlorogenic acid in coffee may inhibit the conversion of liver sugar to glucose in the body, while magnesium ions increase the sensitivity of cells to glucose, thus accelerating the conversion of glucose to liver sugar storage; some substances in coffee promote insulin secretion and reduce the concentration of glucose in the blood.

The researchers point out that these hypotheses still need to be confirmed by a large number of related experiments. The researchers also believe that the activity of insulin is usually weakened by the influence of free radicals, but the phenolic compounds or antioxidants in coffee and tea can eliminate these free radicals and restore the normal activity of insulin. however, this claim has yet to be confirmed.
