If you eat one more gram of salt every day, your risk of heart disease goes up by 6%, and this risk keeps rising the more salt you eat.

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 more salt every day is linked to a higher chance of heart problems and strokes—every extra gram of salt per day raises your risk by a little bit, according to a big review of many studies.

Eating more salt might increase your chances of heart problems as you get older — one big analysis found people who eat a lot of salt have about a 19% higher risk than those who eat less.

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, so cutting down salt for everyone could save a lot of lives.
