Adding salt to your meal at the table is associated with a shorter lifespan and a higher risk of premature death, according to a new study.
Researchers followed up on participants about nine years later and found that the more salt people added to their meals, the greater their chance of dying prematurely. However, those people who consume a lot of salt may lower their risk by eating more fruits and vegetables, the study said.
The American Heart Association recommends that adults consume no more than 2,300 milligrams of salt per day — but notes that the “ideal limit” is 1,500 milligrams per day. Consuming too much salt can raise blood pressure, which in turn can cause heart disease, stroke and kidney disease, according to the Heart Association.
There’s a long track record of scientific research showing that a diet high in salt is risky, but this study adds a new level of caution against adding more to your plate, said lead study author Lu Qi, a professor of epidemiology at the Tulane University School of Public Health and Tropical Medicine in New Orleans.
“More evidence is needed, especially that from clinical trials, before the public takes action,” he said. “However, our findings are in line with the previous studies consistently showing that high sodium intake is adversely related to several health outcomes, such as hypertension and cardiovascular disease.”

Even if you don’t add salt to your own plate, you may be taking in more sodium than you should.
“Most of my patients don’t add salt to the dinner table, but don’t realize that sandwiches, canned vegetables, and chicken breasts are among the biggest culprits. (of high sodium) in the US,” said Dr. Stephen Juraschek, an assistant professor at Harvard Medical School who studies sodium and hypertension.
juraschek was not involved in the 2020 Biobank study or meta-analysis.
But salt makes everything so delicious, you might think.
Knowles recommends cooking at home — where you have more control over the salt shaker as you prepare your meal — more often, reading your produce’s ingredients, substituting no-salt herb and spice blends, and focusing your diet on minimally processed foods.
