This tool gives general information based on the research summarised in Cutting Salt: Where It Actually Comes From. It is not a medical device, does not diagnose, and does not replace advice from your clinician.

Limits: This scales group averages from trials; it does not predict your blood pressure. Blood pressure is a risk factor measure, not an outcome, and this is not treatment advice.
