Investigators said theirs is one of the largest studies ever to include people taking high blood pressure meds in a look at the effect of reducing dietary intake of sodium. She said researchers previously didn't know if people already on blood pressure meds could lower their blood pressure even more by reducing their sodium intake. High blood pressure is a leading cause of illness and death worldwide. Before each study visit, participants wore blood pressure monitors and collected their urine for 24 hours. "The effect of reduction in dietary sodium on blood pressure-lowering was consistent across nearly all individuals, including those with normal blood pressure, high blood pressure, treated blood pressure and untreated blood pressure," Gupta said in a Northwestern news release.
