The more salt you eat, the higher your risk of heart disease — and this keeps going up steadily, with no safe lower limit or point where it stops getting worse.

Eating more salt is linked to heart disease risk — and this link stays about the same no matter how old you are, whether you're a man or woman, how long studies look at people, or how good the studies are.

In Iranian adults, eating more salt is linked to a higher chance of heart problems over time — every extra 1,000 mg of sodium a day is tied to a much higher risk, so cutting back on salt might help protect the heart.

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 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.

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.
