NEW ORLEANS, March 21 (UPI) -- Too much salt led to nearly 2.3 million heart-related deaths worldwide in 2010, U.S. researchers calculated.
Lead author Dr. Dariush Mozaffarian of Brigham and Women's Hospital, Harvard Medical School and the Harvard School of Public Health said the research team analyzed 247 surveys of adult sodium intake, from 1990-2010 as part of the 2010 Global Burden of Diseases Study.
