The Claim

In patients with established cardiovascular disease, an estimated 24-hour urinary sodium excretion between 4.59 and 4.97 grams per day is associated with the lowest risk of major adverse cardiovascular events and all-cause mortality, whereas both lower and higher levels of sodium excretion are associated with increased risk, indicating a J-shaped relationship.

What the research says

Supports is higher

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

In plain English

For people who already have heart disease, eating just the right amount of salt — not too little and not too much — seems to be linked to the lowest chance of heart problems or dying from any cause. Too little or too much salt might actually be riskier.

What the research says

1 study
  1. Study: The relation between urinary sodium and potassium excretion and risk of cardiovascular events and mortality in patients with cardiovascular disease

    This study found that heart disease patients who excrete about 4.6 to 5.0 grams of sodium per day have the lowest risk of heart problems or dying, and those who eat much less or much more sodium have higher risks — just like the claim says.
