Increasing urinary sodium excretion by 1 gram per day is associated with a significant increase in systolic blood pressure (approx. 1.7 mmHg) and diastolic blood pressure (approx. 0.5 mmHg).
For every additional gram of sodium you consume (roughly 1/3 of a teaspoon of table salt), your systolic blood pressure may rise by about 1.7 mmHg. To mitigate this, ensure your potassium intake is adequate, as the study shows potassium helps lower blood pressure.

- Increasing urinary potassium excretion by 1 gram per day is associated with a significant decrease in systolic blood pressure (approx. 1.1 mmHg) and diastolic blood pressure (approx. 0.9 mmHg).Good
- A higher sodium-to-potassium ratio (gram-to-gram) is significantly associated with increased systolic and diastolic blood pressure, with the effect being most pronounced in low-salt regions.Good
