Good news for our regular patrons: Coffee consumption has been strongly associated with a reduced risk of to develop Type 2 diabetes, according to a robust and published study by the Harvard School of Public Health and Brigham and Women’s Hospital.
The research showed that men who drank more than six or more cups of caffeinated coffee per day reduced their risk for type 2 diabetes by more than 50 percent compared to men in the study who didn’t drink coffee at all. For women, that risk was reduced by nearly 30 percent.
"Caffeinated coffee and decaffeinated coffee consumption were both associated with a lower risk of type 2 diabetes,” the research noted. Though the reduction in diabetes risk for decaf was slightly lower, the authors indicated it was statistically about the same.
"We found that a 1-cup/day increment of regular coffee was associated with a 9% reduction in diabetes, and 1 cup/day of decaf was associated with 6% reduction in diabetes, but the difference in risk reduction between the 2 types of coffee was not statistically different," said senior author Frank B. Hu, MD, PhD, a professor of nutrition and epidemiology with the Harvard School of Public Health in Boston, Massachusetts.

More than 125,000 study participants who were free of diabetes, cancer, and cardiovascular disease at the start of the study were selected from the on-going Health Professionals Follow-up Study and the Brigham and Women’s Hospital-based Nurses Health Study. Some 41,934 men were tracked from 1986 to 1998 and 84,276 women from1980 to 1998 via food frequency questionnaires every two to four years to assess their intake of both regular and decaffeinated coffee.

During the span of the study, 1,333 new cases of type 2 diabetes were diagnosed in men and 4,085 among the women participants.
