Caffeinated Coffee Linked to Improved Diabetes Risk Markers
Good news for caffeinated coffee drinkers. A recent Harvard study suggests that it may have a positive effect on certain markers associated with the risk of developing diabetes.
The findings were published on September 13, 2011 in Nutrition Journal.
The study participants included 45 overweight but otherwise healthy 40 year old coffee drinkers. Over the course of 8 weeks, the participants drank five cups of either instant caffeinated coffee, decaffeinated coffee, or water.
At the conclusion of the study, the caffeinated coffee group showed a 60% reduction in blood levels of interleukin-6 when compared to the water group. Interleukin-6 is a compound that contributes to inflammation and is a marker for diabetes.
Participants in the caffeinated coffee group also showed increased levels of adiponectin when compared to the decaffeinated group. Adiponectin is a hormone that helps with the regulation of insulin sensitivity and energy. None of the groups, however, showed changes in blood sugar or insulin levels.
The researchers believe that caffeine is playing a role in the health benefits observed based on the fact that the metabolic effects were more pronounced in participants in the caffeinated coffee group.
Coffee consumption has also been linked to the prevention of Parkinson's disease and dementia, preventing certain cancers, and reducing the risk of stroke.
