BOSTON, MA — One side says everyone needs to cut back on salt to
reduce heart disease risk. The other side says universal salt reduction
would be a needless deprivation for many people. Which is correct?
There isn't a simple answer.
In the most
general terms, getting less sodium (the problematic component of salt)
in the diet lowers blood pressure. But how sodium reduction affects an
individual depends on his or her genes, age, and medical conditions,
reports the November 2006 issue of the Harvard Heart Letter.
an effort to improve the health of everyone in the United States,
organizations like the American Heart Association urge us all to cut
back on salt. But there really isn't a one-size-fits-all recommendation
for daily sodium intake. If you are under age 50, your blood pressure
is in a healthy range, and your health is good, you probably have
little reason to worry about salt intake. A lower-sodium diet is good
for people who are older, who are of African American descent, or who
have high blood pressure or diabetes. These folks should limit their sodium intake to no more than 2,300–2,400 mg a day. People with heart failure or kidney disease are advised to keep their sodium intake under 2,000 mg a day.
