High consumption of dietary sodium increases systolic blood pressure (SBP) and the risk of fatal cardiovascular disease (CVD).
Reduce your sodium intake. High sodium raises blood pressure and increases the risk of fatal heart disease. Aim for lower sodium levels by cooking at home, reading labels, and using herbs and spices for flavor.
StrongSupportsVERY_HIGH confidence
Dietary sodium increased BP with a monotonic dose-response, with identified heterogeneity in this effect by age, race, and hypertensive status; with consistent evidence for higher risk of fatal CVD comparing high vs. low intakes.
Why this rating
The paper classifies the evidence for sodium and SBP/fatal CVD as 'probable or convincing' with a monotonic dose-response.
