High blood pressure is the leading cause of cardiovascular disease. High blood pressure (hypertension) affects approximately 1 billion individuals worldwide. It has been estimated that ninety percent of adults will develop hypertension by age sixty-five. With the application of evolving knowledge, as noted below, we should anticipate delaying the onset of hypertension by a least a decade.
The potassium/sodium ratio is a key factor in regulating blood pressure. Prior emphasis was focused on lowering sodium to moderate blood pressure. Lowering sodium intake is effective means to lower blood pressure. This is because sodium tends to tighten blood vessels. However, newer research suggests increasing potassium has a favorable effect on blood pressure. More specifically, a higher intake of potassium and lower sodium consumption seems to be more beneficial than focusing exclusively on sodium or potassium in reducing the risk of cardiovascular disease.
The advocacy and application of a correct potassium/sodium ratio will result in less hypertension and cardiovascular disease worldwide. A favorable potassium/sodium ratio can be achieved through dietary means. A good start is to avoid pre-made and processed foods. They are very high in sodium.
Fruits and vegetables are high in potassium. Kidney and pinto beans, bananas, tomato sauce, tomato juice and orange juice are especially rich in potassium. Keep in mind, canned beans will likely have added salt; a bag of dried beans is more economical and more healthful. Also look for no salt added tomato sauce. Orange juice with added calcium is more heart healthy.
More than 70 million Americans, or nearly one in three adults are estimated to have hypertension.
Fewer than fifty percent achieve blood pressure control.
Hypertension is the most common reason for visits to physician's offices and the primary reason for prescription drug use.
