Our public health institutions are in complete denial
Once again, a respected medical journal has published a paper demonstrating that low salt diets cause more sickness and death than regular salt consumption. The most recent publication in the British medical journal, Heart, by Drs. DiNicolantonio, Di Pasquale, Taylor and Hackam was published online today (August 21, 2012). The details can be seen at http://heart.bmj.com/content/early/2012/08/21/heartjnl-2012-302337.abstract?papetoc . The medical researchers, from USA, Italy, UK and Canada, carried out a systematic review and meta-analysis of randomized trials with heart failure patients carried out up until April 2012. They concluded that low sodium diets significantly increases morbidity and mortality in patients with heart failure compared normal sodium diets.
This review follows on a recent Cochrane meta-analysis which demonstrated that sodium restriction did not reduce all-cause mortality or cardiovascular events.
Yet, North American guidelines for the management of heart failure consistently advise dietary sodium restriction for patients. The Guidelines for treatment of Heart Failure patients is hopelessly out of date. The letter I wrote to the American Heart Association two years ago asking them to reconsider their guidelines in light of new, peer-reviewed evidence, went completely unanswered. They, together with all our other public health institutions are in total denial of the evidence, and this latest publication confirms this once again. They have committed themselves so deeply to salt- reduction ideology, that no amount of new evidence will shake them from their pig-headed position. As a result, more people will die.
During the past three years there has been a great many medical publications cautioning against salt reduction in food. Peer-reviewed medical publications the world over have stated that salt reduction will result in higher rates of cardiovascular morbidity and mortality for Type I and Type II Diabetes patients. They have repeatedly shown that salt reduction down to the levels to the levels recommended in our dietary guidelines will result in greater all-cause cardiovascular mortality, losses in cognition, increase in unsteadiness and falls in the elderly and a host of other malignant conditions.
It is time our public institutions come clean and do what they are paid to do. They are in our employ to make recommendations based on the preponderance of scientific evidence – not to stake out an intractable position based on dogma and never veer from it, regardless of the consequence to consumers. They are not doing their jobs – even to the point of reading the published research. The position of our public health institutions was aptly described by Bill Watersson, author of the cartoon, Calvin and Hobbs, “It's not denial. I'm just selective about the reality I accept.”
