Sugar: The Bitter Truth

So salt is back in the news. On May 3, 2011 Gina Kolata (one of the best reporters on nutrition issues around) reported on a new study which found that a low salt diet increased the risk of death from heart attacks and strokes and did not prevent high blood pressure. Study Finds Low-Salt Diet Ineffective but Draws Criticism From C.D.C. – NYTimes.com See the abstract  at Fatal and nonfatal outcomes, incidence of hyperten… [JAMA. 2011] – PubMed result. But the real story she reported was the pushback from the Centers for Disease Control and Prevention which seemed to be going out of its way to attack the study. The discussion pointed out the differences in the scientific literature on low salt diets, noting that lowering salt consumption can increase insulin resistance which can increase the risk of heart disease, contrary to prevailing wisdom.  Dr. Lawrence Alderman is quoted with the insight every weight watcher knows, “Diet is a complicated business.” But beyond that, the article shows the complexity ofblood pressure and hypertension, two conditions often associated with obesity but often unpredictable in their response to changes in body weight.
