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 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.

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.

Too little or too much salt might both be bad for your heart — studies show people who eat way too little or way too much salt may be more likely to die from heart problems.

People who eat very little salt—less than 3 grams a day—are more likely to die or have serious heart problems, even when you account for their blood pressure and other health factors.

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.
