Health officials have increasingly pushed the public to reduce their salt intake, but the CDC study comes in the midst of some scientific back and forth over how dangerous dietary salt is. In a review published last week of seven, smaller studies, other researchers found no strong evidence that people with high or normal blood pressure reduce their risk of death by reducing sodium consumption. That review, by the Cochrane Collaboration, had limitations because of its size.

Still, it prompted the Salt Institute _ an industry group _ to call government policy on reducing salt consumption ill-advised.

“In light of this, and other recent research, it is time for the government to cease its costly and wasteful efforts to reduce salt consumption until it can conclusively prove a tangible benefit for all consumers. This can only be done through a large-scale clinical trial on the impact of dietary salt reduction on health outcomes,” said Lori Roman, the Salt Institute’s president, said in a statement.

Alice Lichtenstein, a Tufts University nutrition scientist, said the attention on salt has created a lot of backlash. The CDC study “is a confirmation that dietary salt does matter, and all these public health efforts and the dietary guidelines are appropriate,” she said.
