Good news for black coffee lovers

(Dan Tri) - Drinking black coffee without sugar every day can significantly reduce the risk of type 2 diabetes.

Drinks that reduce the risk of type 2 diabetes by 20-30%

A large-scale study just published has added to the scientific evidence of the benefits of coffee in preventing type 2 diabetes, bringing good news to lovers of this drink.

According to the International Journal of Molecular Sciences, scientists from Pukyong National University and Kyungpook National University (South Korea) compiled and analyzed data from 149 different studies.

Results show that regularly consuming 2-3 cups of unsweetened black coffee per day can reduce the risk of type 2 diabetes by 20-30%.

This effect is thought to be due to polyphenol compounds found in coffee, especially hydroxycinnamic acids such as chlorogenic acid.

These compounds are known for their antioxidant properties, glucose regulation, and improved insulin sensitivity. They positively impact the small intestine, liver, pancreas, and muscle tissue – organs that play an important role in blood sugar control.

Remarkably, both caffeinated and decaf coffee had similar effects, suggesting that coffee's natural bioactives, rather than caffeine, are the key factor.

Experts say that a 30% reduction in the risk of diabetes is an impressive figure, opening up hope for using coffee as part of a disease prevention strategy.

Many other studies also confirm the benefits.

This finding is not unique. Previously, a study by the Harvard School of Public Health (USA) on more than 100,000 people over 20 years also showed that people who drink more than one cup of coffee a day over a long period of time reduce the risk of type 2 diabetes by about 11%.

Another report from the American Diabetes Association (ADA) in the journal Diabetes Care also showed that consuming black coffee helps improve insulin sensitivity and reduce inflammation, two important factors in diabetes prevention.

Professor, Dr. Zhaoping Li, Head of the Department of Clinical Nutrition, University of California (USA), emphasized: "Drinking coffee, if not adding sugar or cream, can become part of a healthy lifestyle."

However, experts also recommend that consumers listen to their bodies and consult their doctors, especially if they have underlying medical conditions such as high blood pressure, digestive disorders or insomnia.

Do not overuse coffee, avoid drinking more than 4 cups a day to avoid causing anxiety, rapid heartbeat or nutritional imbalance. Adding sugar or artificial sweeteners should also be limited to avoid counterproductive effects and negative effects on cardiovascular health.

In Vietnam, about 7 million people have diabetes, with a complication rate of up to 55%, mainly cardiovascular, eye, nerve and kidney complications. The main causes are lack of knowledge about disease care, non-compliance with treatment regimens, and inappropriate diet and exercise.

The Ministry of Health has issued specific guidelines on lifestyle changes to control two important indicators, HbA1c and weight, but the level of interest among patients is still low.
