Sodium reduction significantly lowers blood pressure in individuals with high-normal diastolic blood pressure, producing a net reduction of 0.9 mm Hg in diastolic and 1.7 mm Hg in systolic pressure over 18 months.
Reducing sodium intake can help lower blood pressure in people with high-normal levels. This study showed a small but significant drop in blood pressure (0.9 mm Hg diastolic) after 18 months of sodium reduction. While less effective than weight loss, it is a valid strategy. Focus on reducing sodium through food selection and cooking methods.

Sodium reduction interventions lowered urinary sodium excretion by 44 mmol/24 h (P<.01), diastolic blood pressure by 0.9 mm Hg (P<.05), and systolic blood pressure by 1.7mm Hg (P<.01).
Why this rating
Randomized control multicenter trial with high compliance and blinded outcome measurement.
