What is Diabetes?

When we eat foods that contain sugar, our digestive system breaks it down and turns it into glucose. Glucose is the main source of energy for living cells and helps regulate blood sugars (glucose levels). If you have diabetes, your body can’t use this glucose properly because either:

  • your pancreas  doesn’t make enough insulin
  • your cells don’t respond to the insulin you do produce or both.

These are called type I and II diabetes respectively. There are some other types of diabetes as well, but these two will be discussed here:

  • Type I diabetics must take daily injections of insulin to regulate their glucose levels.
  • Type II diabetics can still make some insulin, but their cells do not respond to the insulin they make. So even though there is some insulin in the body, it doesn’t work. This means that blood sugar stays high after eating.

Diabetes and Coffee

Type two is the most common form of diabetes among adults today. It occurs when a person’s pancreas produces insulin that is not enough. This also happens when the body does not recognize it well enough to use it properly. In this case, you must control your blood sugar levels. One way to do this is by drinking coffee and monitoring the number of cups consumed daily.

Coffee helps regulate insulin in a healthy body. So those suffering from type-two diabetes must be mindful of how much caffeine they consume each day. Consuming too much or too little can have adverse effects on blood sugar levels. Just find the right way to consume coffee. 

People suffering from type-two diabetes should monitor their caffeine intake closely and avoid drinking more than five cups of coffee a day.

Coffee and Diabetes: Prevention 

If you are looking for the best way to prevent diabetes, coffee may be an excellent option. While there is no clear-cut proof that drinking coffee will help in preventing or delaying type two diabetes. Some researches have shown promising results with both caffeine and antioxidants found in common beverages like green tea and coffee.

Coffee has been shown to have positive effects against diabetes. While coffee may help prevent diabetes. However, certain studies have indicated that your ordinary black coffee might be harmful to those who already have type 2 diabetes.

Regularly drinking caffeinated coffee has the potential to alter its impact on glucose and insulin sensitivity. Tolerance may develop over time, producing a protective effect.

Research shows that there may be a genetic component to how we metabolize caffeine. Our blood sugar level is also important. The people who process caffeine more slowly had higher blood sugar levels than those who processed it faster, according to this research. So, it all depends on your metabolism.
