## In plain language

The 2025 World Health Organization guideline on salt substitutes that have part of their sodium replaced with potassium. It suggests that adults in general populations who use table salt replace it with such a substitute, but not people with kidney problems, children or pregnant women.

## Technical summary

WHO guideline dated 27 January 2025 on the WHO publication page; the PDF title page shows only the year 2025. ISBN 978-92-4-010559-1 (electronic version), licence CC BY-NC-SA 3.0 IGO. The recommendation this atlas records from it is conditional, and WHO rates the certainty of the evidence as low overall under GRADE. WHO says global guidance on these substitutes was lacking, and addresses the guideline to policy-makers at all levels. Whether a later WHO edition replaces it was not checked.
