Caffeine's Effect on Glucose Levels

A small Duke University study conducted by Dr. James D. Lane concluded that caffeine may have a harmful effect on glucose levels. Other studies are inconclusive about the effects of caffeine and more research needs to be done.

  1. Time Frame

    • Most studies tested people one to two hours after ingesting caffeine to check for any harmful effects on their glucose levels.

    Function

    • Some studies show that caffeine, particularly regular coffee, decreases insulin sensitivity and increases glucose levels in diabetics when consumed with carbohydrates.

    Significance

    • Research on caffeine and glucose levels may help people manage their glucose levels more efficiently, such as like type 2 diabetics who can sometimes reverse their diagnosis with diet and exercise.

    Warning

    • No study has been large enough to be conclusive so people with fluctuating glucose levels should consult regularly with their doctors.

    Prevention/Solution

    • Since experts can't agree, people with varied glucose levels should consume caffeine in moderation and consider switching to decaf ,which doesn't seem to have the same effect as caffeinated coffee.
