We sought to summarize major recent studies in the field of dietary sodium intake and arterial blood pressure, and discuss the following trials.Intersalt: Sodium intake correlates with the rise in blood pressure with age, but not with the prevalence of hypertension. The population study identified a minimal impact of sodium intake on blood pressure (0.9 mm Hg/10 mmol difference in salt intake).Dash: This diet induced significant reductions in blood pressure compared with the control diet. Further decreases were observed with DASH and a 50 mmol/day sodium intake.Vanguard: Blood pressure was inversely related to urinary potassium, calcium and magnesium but not to sodium excretion.Tone: Cardiovascular events were highest in the usual care group (83%) and lowest in the sodium reduction-plus-weight loss group (56%).Meta-Analysis: A systematic review of 11 long-term controlled randomized trials reported a small decrease (1. 1 mm Hg) in median systolic but not diastolic blood pressure with a reduced dietary sodium intake.In conclusion, (1) sodium restriction in hypertensive patients reduces blood pressure, and (2) the long-term impact of reduced salt intake on blood pressure, mortality, and morbidity remains to be defined.
