Brief: This study included more than 100,000 adults sampled from the general population of 17 countries that varied in their economic development and acculturation to an urban lifestyle. The authors concluded from the findings that a very small proportion of the worldwide population consumes a low-sodium diet and that sodium intake is not related to blood pressure in these persons, calling into question the feasibility and usefulness of reducing dietary sodium as a population-based strategy for reducing blood pressure. In the absence of a randomized trial, these results argue against reduction of dietary sodium as a public health recommendation.
