Coffee, Caffeine and Diabetes

Some days I’m not really a morning person while other days I am. One thing that I do love about mornings is waking up and enjoying a nice cup of joe (coffee).  When I hear coffee, the first thing that comes to mind is Starbucks and their various sugar filled concoctions; but let me inform you that I’m the type of coffee drinker that really enjoys the taste and flavor of plain, black coffee. Even though I enjoy a cappuccino as a morning meal once in a blue moon, I withhold from using cream and sugar in my coffee. Coffee not only gives me an extra boost in the morning but a CNN Health article states that coffee may help reduce the risk of type 2 diabetes. Well I’m a coffee lover and love hearing news about coffee so I decided to dig deeper.

I found a great website showing the health benefits of coffee and explored some of the studies reference regarding coffee and type 2 diabetes. Studies indicated that the development of type 2 diabetes can be reduced with moderate coffee consumption; in fact multiple studies have shown the positive correlation between coffee consumption and reduction in type 2 diabetes. Habitual coffee consumption was also associated with greater insulin sensitivity with one study having results showing that coffee consumption lead to higher fasting glucose and insulin concentrations.

On the other hand, caffeine by itself seems to have a negative effect on managing type 2 diabetes as it can lead to glucose intolerance, insulin resistance and an increase in blood glucose levels when ingesting caffeine with carbohydrates.

The good thing is that the majority of research on diabetes and caffeine reveals that caffeine does not increase the risk of someone developing type 2 diabetes and actually helps to decrease the risk. But for people that are already diagnosed with type 2 diabetes, their caffeine consumption should be limited as it impairs glucose metabolism in diabetics while also increasing blood glucose levels. The big takeaways are that if you have not been diagnosed with type 2 diabetes, then drinking coffee will lower your chances of developing the disease. But if you are already a diabetic (type 1 or 2), then coffee and caffeine intake may need to be limited as caffeine impairs glucose metabolism, reduces insulin sensitivity and raises blood glucose levels.
