This is another good example of how the general public forms an opinion over a product.
Controversy Continues
For many years, the intense public controversy that has characterized the public policy debate over public health nutrition recommendations on salt intake has focused on the wrong question. Medical experts, public health policy-makers – and the public, trying to sort out the issues reading the consumer press – have all focused on the relationship of sodium intake to blood pressure instead of the relevant question of whether changing intake levels of dietary sodium results in improved health outcomes. See, for example, recent Salt Institute comments to the (British) Scientific Advisory Committee on Nutrition.
There is no evidence that reducing dietary sodium improves the risk for heart attacks or strokes for the general population. In 1999, the Canadian Hypertension Society, the Canadian Coalition for High Blood Pressure Prevention and Control, the Health Canada Laboratory Centre for Disease Control and the Heart and Stroke Foundation of Canada issued a joint statement opposing general recommendations for sodium reduction.
The U.S. Preventive Services Task Force has also reviewed the evidence and concluded:
"There is insufficient evidence that, for the general population, reducing dietary sodium intake or increasing dietary intake of iron, beta-carotene, or other antioxidants results in improved health outcomes."
The debate has confused the public. Medical journalists from ABC-TV’s 20/20 to America’s pre-eminent scientific journal, Science, published by the prestigious American Association for the Advancement of Science, have investigated the source of this confusion. The report in Science won author Gary Taubes a top prize from the National Association of Science Writers and has also been translated into French.
Taubes concluded:
“After interviews with some 80 researchers, clinicians, and administrators around the world, it is safe to say that if ever there were a controversy over the interpretation of scientific data, this is it….After decades of intensive research, the apparent benefits of avoiding salt have only diminished. This suggests either that the true benefit has now been revealed and is indeed small or that it is non-existent and researchers believing they have detected such benefits have been deluded by the confounding of other variables.”
The Salt Institute is confident that the higher standards of evidence-based medicine will reduce the ongoing controversy, better inform public policy and reduce consumer confusion. For more information about the importance of evidence-based health, you may wish to visit the Cochrane Collaboration, Oxford University (UK) Centre for Evidence-based Medicine, the Health Information Research Unit (McMaster University) or the Canadian Centres for Health Evidence. Using the latest science, we can create better public health nutrition policy.
