Eating a handful of this fruit per day can reduce the risk of cardiovascular disease.
A daily intake of one cup of blueberries will reduce blood pressure and arterial stiffness, which decreases heart disease risk.
The effect of lowering blood pressure and arterial stiffness may be due to a rise in nitric oxide production in the blood vessels.
Blueberries are a rich source of flavonoids such as anthocyanin, a natural compound that acts as an antioxidant.
Flavonoids have an anti-inflammatory effect as well as increasing the production of nitric oxide in the body.
Nitric oxide can make the inner muscles of the blood vessels relax and so they widen and circulation improves.
By increasing blood flow through the body, blood pressure will consequently go down.
