You might want to put down that salt shaker after reading about these new findings. Researchers examined results from two studies of more than 3,000 people total, one conducted in 1987–1990 and the other in 1990–1995. Those who consumed less than 2,300 milligrams a day of sodium were 25 percent less likely to die over a 24-year period than those whose intake was between 2,300 and 3,600 milligrams daily. Looked at another way, for every additional 1,000 milligrams of sodium a day, the death risk rose by 12 percent. Packaged foods contribute to the salt overload: A standard can of chicken noodle soup, for instance, contains roughly 2,300 milligrams of sodium. That’s the upper limit recommended for the general population as well as those with diabetes, though even lower levels are advised for people with both diabetes and high blood pressure.
