Blueberries reduce the risk of Type 2 Diabetes. The National Institutes of Health says that blueberry consumption enhances insulin sensitivity. For people with Type 2 diabetes, the body becomes resistant to the absorption of insulin. Due to this the pancreas has to work harder to absorb the sugar in the body.

The Journal of Nutrition published an article which said dietary supplements with blueberries increases insulin sensitivity in the body. It lowers the risks of developing the disease.

The University of Prince Edward in Canada conducted a research on the effects of blueberries on elevated blood pressure patients. The research found that the angiotensin converting enzyme (ACE) that was responsible in hardening the arteries leads to elevated blood pressure. But after a regular diet on blueberries, it was observed that the functioning of ACE decreased.
