5. Dark chocolate
This is an excellent dessert and can be taken as a snack, too. Just be sure not to choose dark chocolate brands with added sugars. These should be avoided, especially if you suffer from hypertension and diabetes.
Dark chocolate contains plenty of flavonoids, which are behind its dar color. They go directly to your blood vessels and improve the metabolism of the inner lining, called the endothelium. That is how dark chocolate helps your blood vessels dilate, making up space in the circulatory system and reducing blood pressure levels.
