Cut back on salt and live longer claims a new study.
A new study suggests that by cutting our salt intake, we can live longer. The American Heart Associations Journal just published a study suggesting this can help us live a longer and healthier life. It is no secret that many processed foods rely heavily on salt as a flavor additive. Perhaps, it is time that either the food companies reconsider their excessive use of salt for flavor or maybe, we need to do more home cooking.

Cutting salt could save hundreds of thousands of lives, study says
Steadily reducing sodium in the foods we buy and eat could save a half-million Americans from dying premature deaths over a decade, says a new study. And a more abrupt reduction to 2,200 milligrams per day–a 40% drop from current levels–could boost the tally of lives saved over 10 years to 850,000, researchers have projected.
The new estimates, published Tuesday in the American Heart Assn.’s journal Hypertension, are the results of three separate teams crunching the numbers at the request of the Centers for Disease Control and Prevention. Researchers from UC San Francisco, Harvard University‘s School of Public Health and Simon Fraser University in Canada came at their estimates independently, but found that their results converged.
If the average daily sodium intake of Americans were to drop instantaneously to 1,500 milligrams per day–a steep drop to a level considered “ideal”–as many as 1.2 million premature deaths could be averted over the course of a decade, the teams agreed.
Americans currently consume about 3,600 milligrams of sodium daily–roughly 40% above the “slightly less ambitious” interim goal posited by the researchers–and much of that is hidden in processed foods such as soups, cereals, bread and soups. While the link between sodium intake and high blood pressure is much debated, research strongly suggests that high-sodium diets can push blood pressure above safe limits and exacerbate high blood pressure, and that lowering sodium consumption tends to lower blood pressure. That’s important, because some 45% of cardiovascular disease in the United States is attributed to high blood pressure.
