The human body is comprised of a network of tiny tubes and vessels that function as the transporters of blood. They are vastly are branched out throughout the system, almost akin to a network of roads. When the blood travels through these vessels, it applies pressure along their walls and gives rise to what we commonly call blood pressure. When this blood pressure that is exerted along the walls of these vessels remains elevated for an extended period of time, it gives rise to Hypertension or high blood pressure.
Dashing Your Way to Good Health : A diet rich in fruit, vegetables and whole grains, and low in common salt, saturated and total fat helps lower blood pressure. So says the Dietary Approaches to Stop Hypertension (DASH) study conducted by the National Heart, Lung, and Blood Institute (NHLBI) of America. Coupled with exercise, the DASH diet may eliminate the need for drug therapy when the BP is high.
