Sodium Intake and All-Cause Mortality Over 20 Years in the Trials of Hypertension Prevention.

Cohort Study

Human

2016 Oct 11

This study followed people for 20 years and found that those who ate less salt (under 2,300 mg/day) were less likely to die early than those who ate a lot of salt (over 3,600 mg/day), which matches the claim exactly.

Self-Care and All-Cause Mortality in Patients With Chronic Heart Failure.

Cohort Study

Human

2016 Mar

This study found that heart failure patients who ate less salt actually had a higher risk of dying, which is the opposite of what the claim says. So it contradicts the claim.

Sodium intake and hypertension.

Narrative Review

2006 Sep-Oct

The study says eating less salt helps lower blood pressure and heart disease, but it doesn’t prove that eating under 2,300 mg of salt every day cuts overall deaths by 25% compared to eating over 3,600 mg.

Lowering Sodium Intake: Reduction and Substitution for Cardiovascular Health.

Narrative Review

2025 Jun 6

The study says eating less salt is good for your heart, but it doesn’t show that cutting salt below 2,300 mg gives exactly a 25% lower risk of dying compared to eating more than 3,600 mg.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Eating too little or too much salt might both be bad for your heart — people who eat way less than 3,000 mg or way more than 6,000 mg of salt a day seem to have a higher chance of heart problems or dying from them.

People who eat about 3 to 6 grams of salt per day seem to have fewer heart problems and live longer than those who eat much less or much more salt — it’s like there’s a sweet spot for salt intake.

Eating too much salt—more than 2,000 mg a day—can raise your chances of having a stroke or heart problems, and when whole populations eat less salt, people’s blood pressure tends to drop and fewer people die from heart disease.

Eating too much salt—more than 2,000 mg a day—can raise your chances of having a stroke or heart problems, but cutting back to that level or less may help lower your blood pressure and keep you from dying of heart disease.

Eating a lot of salt—more than 7 grams a day—might make people with high blood pressure more likely to have a heart attack, stroke, or even die sooner.
