In Reply Dr Graudal and Dr Stafford question certain recommendations in the 2015-2020 Dietary Guidelines for Americans.
Graudal is concerned with the recommendation that the average sodium intake of Americans (currently 3440 mg/d) should be reduced. Graudal cites publications arguing that the current sodium intake levels are healthy and reduction harmful. We disagree, as there are serious methodological issues with the studies in question.1 In addition, most scientific bodies agree with the recommended reduction—the World Health Organization, for example, recommends 2000 mg/d, whereas the American Heart Association recommends 1500 mg/d for most people.
