Caffeinated and decaffeinated beverages on type 2 diabetes risk

Consumption of caffeinated beverages such as coffee and tea has been associated with a lower risk of type 2 diabetes (T2D). The objective of the American Journal of Clinical Nutrition study was to examine the association of caffeinated compared with caffeine-free beverages, including coffee, tea, sugar-sweetened beverages (SSBs), and carbonated artificially sweetened beverages (ASBs), with T2D risk.

74,749 women from the Nurses’ Health Study and 39,059 men from the Health Professionals Follow-Up Study who were free of diabetes, cardiovascular diseases, and cancer at baseline were examined.

Irrespective of the caffeine content, SSB and caffeine-free ASB intake were associated with a higher risk of T2D, and both caffeinated and decaffeinated coffee, as well as caffeinated tea intake were associated with a lower risk of T2D.
