Health Impact News
Around 2012, and immediately before and after, Health Impact News featured some seriously thought provoking attacks on reigning dogmatic nutritional salt myths. The reports were from several experts such as Dr. Joseph Mercola, Dr. David Brownstein, author of Salt Your Way to Health, and the satirical approach of Scottish M.D. Malcolm Kendrick.
My favorite Health Impact News article on the matter was by Dr. Kendrick, who explained that the low sodium diets seem to forget that salt is composed of two molecules, salt (Na) and chloride (Cl). The chemical formula for salt is NaCl, or sodium chloride, which is salt.
Then he flashed a study that warned low serum chlorine was more dangerous than previously considered, concluding:
Low, not high Serum Cl- (<100 mEq/L), is associated with greater mortality risk independent of obvious confounders. Further studies are needed to elucidate the relation between Cl- and risk. (Study abstract)
Despite the growing evidence that low sodium causes more harm than high sodium, and using unprocessed salt has more benefits than commercial processed table salt, the mostly unsubstantiated belief that salt needs to be demonized persists. The revelations of good science are continually crushed by the pressures of public health policy.
