Study Links Moderate Coffee Consumption to Reduced Risk of Type 2 Diabetes

Researchers from the Harvard T.H. Chan School of Public Health analyzed data from over 100,000 participants across three decades to explore the relationship between coffee intake and type 2 diabetes. The study included both caffeinated and decaffeinated coffee drinkers, with results showing consistent benefits across both groups—suggesting the protective effects stem from compounds like chlorogenic acid and lignans, not just caffeine. These antioxidants are believed to improve insulin sensitivity and reduce inflammation, key factors in preventing type 2 diabetes. The study also noted that the risk reduction was most pronounced in participants who maintained moderate consumption (2-4 cups per day) and declined slightly with higher intake (5+ cups). Lead researcher Dr. Sarah Johnson emphasized that “coffee should be part of a balanced diet, not a standalone solution,” as excessive consumption can lead to sleep disturbances or digestive issues. Public health experts have welcomed the findings, adding to a growing body of evidence supporting coffee’s potential metabolic benefits.
