Caffeine and Insulin
* Caffeine affects insulin sensitivity, which may protect you from developing Type 2 diabetes,
* However, if you already have diabetes, caffeine can cause a rise in blood glucose
Caffeine in Non-Diabetics
A 2011 cross-sectional study published in “Diabetalogia” investigated the effects of caffeinated and decaffeinated coffee on insulin sensitivity in a group of non-diabetics. The study showed a positive relationship between caffeine and insulin sensitivity.
Caffeine on Type 2 Diabetic Men
A 2004 study published in the “Journal of Nutrition” tested the effects of caffeine on insulin sensitivity and blood sugar in a group of men with Type 2 diabetes. This study found that, while caffeine increased blood insulin levels, it did not improve blood sugars. In fact, blood sugars were elevated following the ingestion of caffeine.
