About DASH Diet Sodium Calculator

Compares current sodium intake with the chosen DASH level and phases the reduction across the weeks you allow.

Formula

DASH sodium levels

Standard DASH allows 2,300 mg sodium a day and the lower level 1,500 mg; one teaspoon of table salt is about 5.9 g, containing 2,300 mg sodium

Worked example

With the default values below, DASH Diet Sodium Calculator returns Sodium reduction needed of 1,900. Change any input above and every figure here is recalculated in your browser.

Frequently Asked Questions

How much does DASH lower blood pressure?

The DASH-Sodium trial showed about 8 to 14 mmHg systolic reduction combining the diet with the lower sodium level.

Why phase the reduction?

Salt taste preference adapts over several weeks, so gradual reduction is far easier to sustain.
