Abstract
Dietary salt intake and urinary sodium excretion were compared in normotensive and hypertensive subjects in Renfrew, Scotland. All groups had high 24-hour urinary salt excretions, and hypertensive subjects did not eat or excrete more salt than normotensive subjects. The only significant relations found were a lower sodium excretion in hypertensive women than in normotensive women (p < 0.02) and a lower urinary sodium concentration in hypertensive men than in normotensive men (p < 0.05). These data provide no support for the hypothesis that dietary salt is a major cause of hypertension.
