According to the September ’11 Bottom Line Health, an eight-year study followed more than 3,600 men and women aged 60 and younger. All had normal blood pressure.
The researchers found that the one-third of subjects who had the highest sodium intake had only a slight rise in blood pressure.
More surprising was that the one-third who had the lowest salt intake—an average of 2,500 milligrams a day—were 56 percent more likely to suffer a heart attack or stroke than the group consuming the most salt.
The author of the article, Michael Alderman, M.D., said, “Lower sodium levels reduce blood pressure but also increase resistance to insulin and sympathetic nervous system activity, including heart rate. If sodium levels fall too much, it can damage the cardiovascular system.”
