On the assertion that a moderate restriction of sodium intake may have adverse health effects.

The claim in a recent review by Muntzel and Drüeke in the American Journal of Hypertension (1992;5:1S-42S) that a moderate restriction in sodium intake may result in health risks is not supported by the evidence provided nor by any other in the literature. The adverse effects which are observed with severe sodium depletion are not relevant to the possible dangers of reducing sodium intake in humans to levels that are attainable and feasible.
