Sodium and potassium in high blood pressure

Abstract

Abstract: High blood pressure, or hypertension, is the major risk factor in cardiovascular disease. Although there appears to be genetic susceptibility to high blood pressure, environmental factors are needed too for them to become manifest. Obesity is a major factor in high blood pressure. Research has proved salt is also a major factor. The threshold for salt taste depends on the availability of salt; it fluctuates like other psychophysical thresholds. Moderate to stringent restriction of salt, depending on the severity and length of time, will ameliorate or, possibly, eliminate high blood pressure. High potassium levels also appear to prevent or to lessen symptoms of high blood pressure. In view of the proved position of salt as a factor in hypertension, informed consumers are demanding an adequate range of tasty, salt-free foods.
