Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
Whatever salt you use, less of it could be good for your healthThe result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings.
Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco, was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
