The Claim

Do older people and non-white populations benefit more from cutting salt than others?

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

People who are older, Black or Asian, or already have high blood pressure see a bigger drop in their blood pressure when they cut salt than younger, white, or healthy people do.

See the scientific wording

The blood pressure-lowering effect of sodium reduction is significantly greater in older adults (≥65 years), non-white populations, and individuals with higher baseline systolic blood pressure (≥140 mm Hg), indicating that these groups experience disproportionately greater benefit.

What the research says

1 study
  1. Study: Effect of dose and duration of reduction in dietary sodium on blood pressure levels: systematic review and meta-analysis of randomised trials

    This study found that when people cut back on salt, their blood pressure drops more in older people, non-white people, and those who already have high blood pressure — exactly what the claim says.
