A recent report commissioned by the Center for Disease Control (CDC) reviewed the health benefits of reducing salt intake and the take-home message is that salt, in the quantities consumed by most Americans, is no longer considered a substantial health hazard. What the CDC study reported explicitly is that there is no benefit, and may be a danger, from reducing our salt intake below 1 tsp per day. What was absent about the report was is the difference between healthy mineral salts and iodized table salt.
It may be that we’re better off with more salt than less, up to 2 or even 3 tsp per day. How did it happen that such standard medical advice drifted astray, then went un-corrected for so long?
This review by the National Academies Institute of Medicine (IOM), commissioned by CDC, considered dozens of studies, from cross-cultural (less reliable) to prospective, randomized with control (most reliable). Most studies showed no relationship between salt intake and any health outcome. Some seemed to indicate that more salt had a beneficial effect.(Full story here).
Makes you wonder what other basic health advice from the government is wrong. Maybe if people starting eating more salt, it will reduce the explosion of neurological disorders that have arisen since the powers-that-be started trying to limit our salt intake.
