The American Heart Association reports that salt consumption among Americans has risen by 50 percent and blood pressure has risen by nearly the same amount since the 1970s - despite evidence linking salt intake to high blood pressure and heart disease.
"In addition to its independent benefits on blood pressure, reducing salt intake can enhance the effects of most anti-hypertensive (blood pressure lowering) agents and reduce complications associated with diabetes, obesity and kidney disease," said Glenn M. Chertow, MD, study co-author, professor of medicine and chief of the Division of Nephrology at Stanford University.
According to federal government data, the average American man consumes more than10 grams of salt (4000 mg sodium) daily. Most health organizations recommend far lower targets - no more than 5.8 grams of salt per day (2300 mg sodium) and less than 3.8 grams for those over 40. Each gram of salt contains 0.4 grams of sodium.
"It's clear that we need to lower salt intake, but individuals find it hard to make substantial cuts because most salt comes from processed foods, not from the salt shaker," Bibbins-Domingo said. "Our study suggests that the food industry and those who regulate it could contribute substantially to the health of the nation by achieving even small reductions in the amount of salt in these processed foods."
