Salt intake

Some experts say that the pervasive use of sodium in the American diet is wreaking havoc on our cardiovascular systems. "Sodium causes retention of fluid within the circulation, and if you're sodium-sensitive, it expands your blood volume and can contribute to high blood pressure, stroke, and other heart disease," explains Clyde Yancy, chief of cardiology at Northwestern University Feinberg School of Medicine.
A report in the New England Journal of Medicine suggested that if Americans reduced daily salt intake by 3 grams, we could significantly lower the annual number of new cases of coronary heart disease (by between 60,000 and 120,000), stroke (by 32,000 to 66,000), heart attack (by 54,000 to 99,000), and even the number of deaths from any cause (by 44,000 to 92,000). The paper's authors noted previous research that showed the average American man consumes 10.4 grams of salt daily, while the average American woman gets 7.3 grams.
Bottom line: The AHA recommends Americans limit salt intake to 1.5 grams daily. Be wary: Sodium creeps in via unexpected sources, and it's not so much the salt shaker on our table that's to blame. Research suggests we get as much as 80 percent of our daily salt intake from processed foods. Some surprising foods loaded with salt include miso soup, cottage cheese, salsa, and dill pickles.
