4. Reduces the risk of type 2 diabetes

Diabetes, a huge health problem affecting more than 400 million people worldwide, affects 8% of adults over the age of 18. Type 2 diabetes is characterized by high blood sugar levels due to resistance to the effects of insulin.
A review of the effects of coffee in people with type 2 diabetes found that drinking coffee helps normalize blood glucose levels. It affects glucose tolerance, insulin resistance, and glucose absorption. Coffee also has anti-inflammatory and antioxidant properties that are useful in treating diabetes.
Total daily consumption of at least three cups of coffee can reduce the risk of type 2 diabetes by approximately 42%.
If you are concerned about diabetes, you may want to start including coffee in your diet on a regular basis to improve your chances of preventing it. But be sure to limit the sugar you add or replace it with healthier sweeteners.
