Implications for practice and research
■ Low sodium diet in normotensive Caucasians showed less than 1% decrease in systolic blood pressure (SBP) and 3.5% decrease in hypertensive Caucasian populations.
■ Further controlled studies are needed on the effect of sodium reduction among Blacks and Asians.
■ Sodium reduction diet resulted in significant increase in lipids (plasma cholesterol and triglycerides) and hormones (renin, aldosterone, and catecholamine).
■ Research on long-term hormonal and lipid effects of sodium restriction diets is needed.
Low sodium diets have been a major hypertension prevention and treatment theme. Evidence supporting interventions of reduced sodium intake as a generalised hypertension prophylaxis initiative remains ambiguous.1 Although a diet high in sodium has …
