Long-term study highlights link between sodium intake, mortality

October 21, 2016

Risk for mortality appears increased in people who consume high amounts of sodium and lower in people with reduced sodium intake, according to 2 decades of follow-up data from the Trials of Hypertension Prevention.

“Numerous randomized trials and observational studies have demonstrated a direct relationship between dietary sodium intake and blood pressure,” Nancy R. Cook, ScD, associate biostatistician at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, and colleagues wrote in the Journal of the American College of Cardiology. “How well this blood pressure reduction translates into a beneficial effect on incidence of CVD and particularly on total mortality remains controversial.”
