Dietary effects on blood pressure
1980
Heyden, S. | Hames, C.G.
Dietary factors appear to contribute to the development and treatment of hypertension. Low dietary intakes of potassium play a significant role in this disease among black hypertensives. The epidemic prevalence of hypertension in industrialized nations may be due to high sodium intakes of their populations, or to high urinary potassium excretion. Low-sodium diets may be therapeutic in hypertension as a result of lower urinary potassium excretion. No conclusive evidence exists to support a conclusion that weight reduction per se lowers high blood pressure, since low calorie diets also have markedly reduced sodium content. Other studies suggest that dietary linoleate has an effect on blood pressure. These data indicate that high intakes of linoleic acid lead to increased prostaglandin synthesis, natriuresis, and a decline in blood pressure. (nzm)
