A population-wide reduction of dietary salt by 3 g per day (approx. 1200 mg sodium) significantly reduces the incidence of coronary heart disease, stroke, and myocardial infarction, and lowers all-cause mortality.

Reduce your daily salt intake by approximately 3 grams (about 1200 mg of sodium). This is a significant public health target, not just a minor tweak. Focus on processed foods, which provide 75-80% of dietary salt. The benefits include fewer heart attacks, strokes, and deaths, and it is cost-saving for the healthcare system. Start gradually if needed, as your taste buds will adapt.

GoodSupportsHIGH confidence
Reducing dietary salt by 3 g per day is projected to reduce the annual number of new cases of CHD by 60,000 to 120,000, stroke by 32,000 to 66,000, and myocardial infarction by 54,000 to 99,000 and to reduce the annual number of deaths from any cause by 44,000 to 92,000.

Why this rating

Based on a validated computer simulation model (CHD Policy Model) using data from national surveys and meta-analyses, though it is a projection rather than a direct long-term RCT.
