The next time you getting some coffee you may think twice before deciding between regular or decaf.

Population based studies have found evidence that coffee consumption is linked to a decrease risk of type 2 diabetes.

The mechanism is not understood, however, coffee is known to contain a variety of polyphenols that could be responsible for providing a protective effect.

A recent study was published in the British Journal of Nutrition to test decaffeinated coffee for improving insulin sensitivity.

Here are the details of the study

Design: Randomized crossover single blind clinical trial

Coffee: Participants consumed either

– Regular coffee

– Regular coffee with sugar

– Decaffeinated coffee

– Water (control)

– Water with sugar (control)

Here are the main results

– Decaffeinated coffee led to a 97.5% increase in Insulin sensitivity compared to water

– Regular coffee did not result in any difference in insulin sensitivity

Here are the comments by the authors

Our findings demonstrated that the consumption of decaffeinated coffee improves insulin sensitivity without changing incretin hormones levels.
