Excess salt can cause or worsen high blood pressure and raises the risk for cardiovascular disease.
This is not the first time Americans' favorite dietary supplement has hit the news in recent days.

The New York City Health Department, under Mayor Michael Bloomberg, has announced that it is spearheading the "National Salt Reduction Initiative," which aims for a 20 percent reduction in salt consumption over five years.
The initiative is targeted primarily at restaurants and food manufacturers, which supply the gross majority of sodium in American diets.
Only about one-quarter of the salt in the U.S. diet comes directly from the kitchen table salt shaker.
The researchers, from the University of California, San Francisco, fed previously published data on heart disease in U.S. adults aged 35 to 84 into a computer model.
The model then predicted that the reduction of 3 grams of salt a day would cut the number of new cases of coronary heart disease each year by 60,000 to 120,000; stroke by 32,000 to 66,000 cases; and heart attacks by 54,000 to 99,000.
The annual number of deaths from any cause would be reduced by 44,000 to 92,000.
Limiting salt intake would be good for the fiscal diet as well, saving an estimated $10 billion to $24 billion in health care costs yearly, the paper found.
But if Americans cut even a mere 1 gram of salt from their meals and snacks every day, the effects would still be stunning, the authors stated: 20,000 to 40,000 fewer cases of coronary heart disease; 18,000 to 35,000 fewer heart attacks; 11,000 to 23,000 fewer strokes; and 15,000 to 32,000 fewer deaths.
Given that so much sodium comes from processed food, the authors urged a public health initiative to curb consumption.
