High salt intake, its origins, its economic impact, and its effect on blood pressure

      A number of years ago, when dining, I would cover the food on my plate with a heavy dose of salt before taking a single bite. After a while, I noted my blood pressure was a bit elevated and I abruptly stopped adding salt at the table. Within a month I found that I did not miss the added salt one iota. Unfortunately, salt added at the table accounts for only about 15% of the salt most Americans consume. Why is it that salt, so beneficial as a preservative and added to food for thousands of years, should only in recent years be discovered to be so harmful? MacGregor and de Wardener
