Behind the Taste of Coffee… A Disruption to Your Inner Balance

Coffee is one of the most widely consumed beverages in the world, and research on its health effects has long been divided between those highlighting its benefits and others warning against excessive intake.

However, recent studies have begun to reveal positive links between coffee consumption and improved markers related to type 2 diabetes. Scientific findings suggest that each additional cup of coffee may help reduce the risk of developing the disease by up to 6%, regardless of caffeine content.

While the exact biological mechanisms behind this effect are not yet fully understood, researchers are focusing on certain compounds like polyphenols—abundant in coffee—which may play a protective role by improving the body’s insulin response.

In this context, a recent Korean study highlighted the relationship between coffee intake and better glucose metabolism in adults. It found that drinking two cups of coffee per day was associated with a notable reduction—up to 23%—in fasting insulin levels and insulin resistance markers.

This positive effect was especially pronounced among women, particularly those who drank coffee regularly. The data showed a 27% improvement in insulin resistance and a 30% drop in fasting insulin levels with the consumption of two or more cups daily. Increasing the intake to three cups nearly doubled the benefits, with reductions of 34% and 36%, respectively.

What stood out in the study was that black coffee—free from cream and sugar—proved more effective in enhancing glucose control and insulin sensitivity. This supports health recommendations that encourage consuming coffee in its purest form.

Drinking two cups of black coffee daily was linked to a 36% decrease in the two main markers of metabolic health. These findings suggest that coffee, when consumed moderately and without additives, may help improve metabolic function and reduce the risk of diabetes, particularly among women.
