Coffee may lower risk for developing type 2 diabetes

A study of more than 4,000 Koreans adds evidence that drinking coffee may lower the risk for developing type 2 diabetes and reveals that a genetic factor could be involved. The researchers found both Korean men and women who drank at least one cup of black coffee a day were less likely to develop prediabetes or type 2 diabetes than those who drank no coffee. The association between drinking coffee and lowered risk for type 2 diabetes was strongest for Koreans with a genetic variation known as rs2074356, which was recently found to be linked with habitual coffee consumption
