The Monday Morning Stimulus

A small, hidden difference in how the body processes caffeine appears to shape diabetes risk in ways everyday habits fail to explain. The signal does not come from the coffee cup, but from what happens after caffeine enters the bloodstream.

Genetic differences that slow the body’s breakdown of caffeine were associated with about 19 percent lower odds of type 2 diabetes, independent of coffee intake. Using DNA as a guide, researchers at the Karolinska Institutet (KI) looked past coffee cups and focused on caffeine levels inside the body.

Dr. Susanna C. Larsson led the work at KI and coordinated data analysis for this project. Her team studies how diet-related exposures and genetics combine to shape long-term risk for metabolic and heart disease. The results put caffeine biology, rather than beverage habits, at the center of debates about weight and diabetes.
