In a 2-year controlled trial, 31 hypertensive patients were instructed to reduce sodium intake by about 70 to 100 mEq, and the average diastolic blood pressure fell, a result similar to that obtained by drug treatment.
.4dditional studies suggest that even smaller reductions in sodium intake over an extended period may reduce blood pressure, as discussed below. In a 2-year controlled trial, 31 hypertensive patients were instructed to reduce sodium intake by about 70 to 100 mEq. Although sodium excretion declined only from 191 to 157 mEq, indicating a much smaller reduction in intake, the average diastolic blood pressure fell by 7.3 mm Hg, a result similar to that obtained by drug treatment (Morgan et al. 1978).
