Increasing Daily Coffee Consumption May Protect Against Type 2 Diabetes

Coffee: The antioxidant-filled beverage is adding another benefit to its ever-growing roster.

A new study published in the journal Diabetologia has revealed that increasing your daily consumption of coffee may help protect against diabetes.  According to the researchers, individuals who increased their daily coffee intake by more than one cup over a four-year period had an 11 percent lower risk of developing type 2 diabetes.

The findings further strengthen previous research linking coffee consumption with a reduced diabetes risk.

“The link between coffee consumption and type 2 diabetes is pretty well established,” lead author Shilpa Bhupathiraju, research fellow in the department of nutrition at Harvard School of Public Health, told  “What we don’t know is what happens when people change their consumption.  That’s never been studied, but that reflects people changing their diet in real life.”

For their research, Bhupathiraju and her team utilized data from three large cohorts: 48,464 women in the Brigham and Women’s Hospital-based Nurses’ Health Study (1986 – 2006); 47,510 women in the Nurses’ Health Study II (1991 – 2007); and 27,759 men in the Health Professionals Follow-up Study (1986 – 2007).  For all the groups, diet was assessed every four years, while medical and lifestyle changes were reported every two years.  Over the study periods, 7,269 people developed type 2 diabetes.

The researchers found that changing coffee consumption – either increasing it or lowering it – had an impact on the risk for diabetes.
