Blueberries increase immunity and reduce blood pressure

A recent study finds that blueberries are even healthier than ever imagined. 
If we review the landscape of health issues, two that lie at the root of a variety of health conditions are a  lack of immune cells and a stiffening of the blood vessels.
When our immune system is deficient in  natural killer T-cells the body can be subjected to a variety of autoimmune disorders. Cancer and tumour growth are also related to a lack of natural killer T-cells. And without enough natural killer T-cells, a minor infection can turn into a disaster.
When our blood cells become stiff, they are not able to pump as much blood around the body. This also leads to hypertension - high blood pressure - and the various issues that relate to that, including kidney issues and heart disease.
