Caffeinated Coffee Increases Blood Sugar
Is it safe to drink coffee when your have diabetes? This is a controversial topic. Coffee is known to prevent the risk of developing type 2 diabetes mellitus, but various research claim that it's caffeine content can mess up with the body's ability to use glucose for energy, which can lead to high blood glucose level.

Caffeine decreases our body's ability to respond to the glucose lowering effect of insulin, which can potentially increase blood sugar level especially among people with diabetes mellitus.
Insulin sensitivity refers to the body being able to respond to the effect of insulin. Insulin is a hormone produced by the pancreas which enables the transport of glucose into the cells of the body. When an individual eats a meal, blood sugar level rises so the pancreas release insulin into the blood stream to counteract this thereby, maintaining balance.
People with type 2 diabetes have decrease sensitivity to the effect of insulin. It is said that they have insulin resistance.
Caffeine reduces insulin sensitivity
When we ingest caffeine, our cells become less sensitive to the effect of insulin. Insulin facilitates the transport of glucose from the blood into the cells of the body where these will be converted to energy. Because our cells become less responsive to insulin, glucose accumulates in the blood stream resulting to high blood sugar level or hyperglycemia.
Caffeine can be found in food products like chocolate, tea, and carbonated beverages, but most people usually get their daily dose of caffeine from coffee. An average person usually consumes roughly 300mg of caffeine in a single day. That is equivalent to 3 cups of regular coffee.
A study by Keijzers and colleagues reveals that caffeine can decrease insulin sensitiy in healthy humans by 15%. The cause of decreased response to insulin is hypothesized to be caused by an increase in epinephrine level brought about by caffeine.
Caffeinated vs. Decaffeinated
Research by Moisey and colleagues reveals that ingesting caffeinated coffee significantly increases insulin resistance compared with taking decaffeinated coffee.
Benefits of Coffee
Studies also shows that coffee helps decrease risk of developing cardiovascular disease, stroke, cancer, Alzheimer's disease, Parkinson's disease, and even diabetes mellitus itself. Coffee is a rich source of antioxidants which does have proven benefits.
Decaffeinated coffee may be the best alternative for people with diabetes since it contains the health benefits of coffee, but without the insulin resistance brought about by caffeine.

Caffeine decreases insulin sensitivity, thus increasing insulin resistance.

Did you know that your brain and liver don't need insulin to use glucose for energy.
