Green Tea and Coffee: The Dynamic Duo for Improving Insulin Sensitivity – A Study

-

Many always look for ways to improve health and prevent disease. Recently, a study(1) examined whether drinking a beverage containing catechins from green tea and chlorogenic acid from coffee can improve insulin sensitivity.

You may already know that green tea and coffee are rich in polyphenols, which are plant compounds beneficial to our bodies. Green tea is particularly rich in catechins, while coffee is rich in chlorogenic acid. Previous observational studies have suggested that consuming these beverages reduces the risk of type 2 diabetes(2). But, the question is whether drinking a liquid that explicitly contains catechins from green tea and chlorogenic acid from coffee can improve insulin sensitivity.

The study was a 3-week randomized crossover trial involving 11 healthy men. Participants drank either a drink fortified with green tea catechins and chlorogenic acid (620 mg green tea catechins, 373 mg chlorogenic acid, and 119 mg caffeine) or a placebo drink (119 mg caffeine) daily. After 2 weeks, the participants switched to the other intervention. 

This study measured the amount of glucose, insulin, and other hormones in the men’s blood after they ate a 592 kcal high-fat cookie (50% energy from Carbohydrates) and drank the drink.

The results showed that the men who drank the special drink had lower maximum glucose levels. Their insulin and other hormones were affected differently than those who consumed the regular drink. These changes suggest a positive impact on insulin sensitivity.

It is important to note that this study only included healthy men, so it is unclear whether the results would be the same for people with type 2 diabetes or insulin resistance. However, this study suggests that drinking a unique beverage containing green tea and coffee compounds may be a simple and beneficial addition to a healthy lifestyle. More research is needed to confirm these results, but it is worth considering!
