Coffee Drinkers Enjoy Lower Risk of Diabetes


The results of a meta-analysis that involved nearly 1.2 million study subjects showed a significantly decreased risk of developing type 2 diabetes for those who drink coffee as compared to non-coffee drinkers.

30 prospective studies were included in the meta-analysis and researchers found that participants who had the highest coffee intake (median intake = 5 cups/day) had a 29% lower risk of developing type 2 diabetes. Compared to non-coffee drinkers, the research showed that for every one cup per day increase in coffee consumption, the risk of developing type 2 diabetes was lowered by 7% for caffeinated coffee and 6% for decaffeinated coffee.

The researchers suggest that coffee’s antidiabetic effects are associated with its numerous compounds that influence and affect blood sugar levels. These compounds include cafestol, caffeine, caffeic acid, chlorogenic acid, and more. The researchers concluded, “Available evidence indicates that coffee consumption is inversely associated with risk of type 2 diabetes. Possible mechanisms behind this association include thermogenic, antioxidative, and anti-inflammatory effects; modulation of adenosine receptor signaling; and microbiome content and diversity.”

This study confirms previous research showing coffee’s protective effects against type 2 diabetes. It’s yet more research that clearly illustrates the multiple health benefits that may be enjoyed by drinking coffee.
