The Starbucks Vaccine Against Diabetes?

Comments Off

Great news for coffee drinkers…and Starbucks.

A newly released medical study says drinking coffee appears to reduce the risk of Type 2 diabetes. (Arch Intern Med 2006;166:1311-1316)

Consumption of coffee, particularly the decaffeinated variety, is associated with a reduced risk of type 2 diabetes, according to a report in the Archives of Internal Medicine for June 26.

The present study is not the first to document this association. However, from previous studies, it was unclear if the link held true across different age groups and body weights and if the caffeine component was the main ingredient responsible for the anti-diabetes effect.

The coffee ingredients responsible for the possible protective effect remain unclear. Intake of two coffee components, magnesium and phytate, did not account for the association seen. Caffeine intake from all sources had no bearing on diabetes risk.

Still, the authors point out that the study “was not equipped to thoroughly explore possible causal mechanisms for this association. Although the first line of prevention for diabetes is exercise and diet, in light of the popularity of coffee consumption and high rates of type 2 diabetes mellitus in older adults, these findings may carry high public health significance.”
