The effect of dietary sodium modification on blood pressure in adults with systolic blood pressure less than 140 mmHg: a systematic review

Background Modifying dietary sodium intake is a cornerstone of diet advice for lowering blood pressure (BP) under the assumption that it is protective against cardiovascular disease. Previous meta-analyses of normotensive participants have not excluded all studies that recruited participants with systolic blood pressure (SBP) > 140 mmHg, which greatly hinders generalization to the wider normotensive population. Objectives The objective of this review was to identify the effectiveness of reducing or increasing sodium intake on BP in normotensive participants with SBP ≤ 140 mmHg

The effect of dietary sodium modification on blood pressure in studies of subjects with systolic blood pressure less than 140mmHg: A systematic review protocol

The objective of this review is to establish the effect of modifying dietary sodium intake in normotensive subjects. More specifically, the objectives are to identify the effect of reducing or increasing sodium intake on blood pressure in normotensive subjects with systolic blood pressure (SBP) <140mmHg, and the effect of sodium reduction or supplementation on arterial function in subjects with baseline SBP <140mmHg
