Reuters (8/2, Rapaport) reports that research published in the Journal of the American College of Cardiology suggests “the amount of salt a typical American adult consumes” daily “may be enough to damage the heart muscle and make it harder to pump blood.” The study indicated that half of the participants consumed at least 3.73 grams of sodium each day. Investigators found that “compared with adults who ate less sodium, people who consumed more than 3.7 grams of sodium a day were more likely to have enlargement in the left chambers of the heart that are responsible for pumping oxygen-rich blood into the body.” These people “were also more likely to have signs of muscle strain in the heart that can precede structural damage.
