The Claim

Among overweight older adults without prior cardiovascular disease or hypertension, a higher urinary sodium/potassium ratio is associated with a 19% increased risk of all-cause mortality over a 5-year period, suggesting that the balance between sodium and potassium intake may be more important than either nutrient alone in this subgroup.

Supports is higher

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

In plain English

For older adults who are overweight but don’t have heart disease or high blood pressure, eating more salt than potassium might raise their chance of dying within 5 years by about 19%—so it’s not just how much salt or potassium you eat, but how they balance each other.

1 study
  1. Study: Sodium and potassium intake and risk of cardiovascular events and all-cause mortality: the Rotterdam Study

    In overweight older adults without heart problems, this study found that people with more sodium and less potassium in their urine were 19% more likely to die over 5 years — just like the claim said.
