A very bad day for salt nannies continues.
The New York Times reports:
There are physiological consequences of consuming little sodium, said Dr. Michael H. Alderman, a dietary sodium expert at Albert Einstein College of Medicine who was not a member of the committee. As sodium levels plunge, triglyceride levels increase, insulin resistance increases, and the activity of the sympathetic nervous system increases. Each of these factors can increase the risk of heart disease.
“Those are all bad things,” Dr. Alderman said. “A health effect can’t be predicted by looking at one physiological consequence. There has to be a net effect.”
Medical and public health experts responded to the new assessment of the evidence with elation or concern, depending on where they stand in the salt debates.
“What they have done is earth-shattering,” Dr. Alderman said. “They have changed the paradigm of this issue. Until now it was all about blood pressure. Now they say it is more complicated.” The report, he predicted, “will have a big impact.”
