In recent years, a series of studies published by academic institutions in Europe and the United States have found that people who drink coffee every day have significantly lower fasting and postprandial blood sugar than those who do not drink coffee.

A 10-year study of 17000 people by scholars at the National Institute of Public Health in the Netherlands and published in the authoritative medical journal Lencet found that the more coffee you drink, the lower the risk of developing type 2 diabetes, that is, coffee consumption is significantly negatively correlated with diabetes. A study published by Finnish scientists in the American Medical Journal (JAMA), which followed more than 14000 people in the country for 12 years, found similar results. People who drank 3 to 4 cups of coffee a day in ─ reduced their diabetes risk by 30%.

But paradoxically, in 2008, Duke University in the United States published a study with the opposite results, throwing a shock bomb for the medical community. The team, led by Dr. James D. Lane, set up continuous blood glucose monitors on 10 people with type 2 diabetes who drank an average of four cups of coffee a day, but stopped drinking it temporarily during the study and switched to a caffeine capsule for breakfast and lunch, and a non-caffeinated placebo the next day.

It was found that blood sugar increased by an average of 8% after taking caffeine capsules and by 10% to 20% higher after meals than when taking a placebo.

Summing up the results of different studies, we can find that although coffee has the effect of stabilizing blood sugar, it is not due to caffeine. on the contrary, too much caffeine will offset the benefits of coffee, especially for people with diabetes.

Dr Rob Van Dam, of the Harvard School of Public Health, believes that perhaps antioxidants other than caffeine, such as chlorogenic acid, play a protective role in reducing the risk of diabetes in the long term. He also suggests that people with hyperglycemia or diabetes have poor glucose metabolism, so it's best to drink less coffee or switch to decaffeinated coffee, as for generally healthy people.
