Last year, the Federal CDC backed off from 50 years of advising everyone (and especially heart patients) to limit their salt intake. \u00a0A meta-analysis of many studies showed that eating salt was not associated with increased risk for any disease. \u00a0Here is my blog on the subject<\/a>\u00a0from last June.<\/p>\n

Feel free…<\/figcaption><\/figure>\n

Now that the doors have been opened to question long-established medical advice, a bit more of the truth has emerged: \u00a0Cutting back salt is dangerous. \u00a0Risks for mortality and various cardiovascular outcomes were 10-15% higher for people who cut back on salt<\/strong>, compared to people who salted their food to taste. \u00a0That’s a lot of excess disease, and the number of people who have been affected is many millions. \u00a0In my opinion, it is a major scandal that epidemiologists have failed to correct their stand over a period of 50 years.<\/p>\n

Results were consolidated from 25 different published studies, using different criteria and different age ranges. \u00a0It took some fancy statistical footwork. \u00a0Even more challenging is the fact that most people who are limiting sodium intake are doing so because doctors have told them they have elevated risk for heart attacks. \u00a0So it’s not straightforward to compare the risks among low-salt and normal-salt groups, because they’re not comparable populations. \u00a0The authors of this study understand this, of course, and claim to have done the statistics appropriately. \u00a0My guess is that there was a tendency to under-state the difference, both because the results are so damning to the medical establishment, and because larger claims expose the authors to more criticism. \u00a0For these reasons, it is likely that the reported cost of lowering salt intake may rise further from 10-15% reported here in coming years.<\/p>\n

The article was titled\u00a0Compared With Usual Sodium Intake, Low-and Excessive-Sodium Diets Are Associated With Increased Mortality: A Meta-Analysis<\/a><\/p>\n

Lead author of the study, Dr Niels Graudal of Copenhagen University says,\u00a0\u201cThe good news,\u201d he says, \u201cis that around 95% of the global population already consumes within the range we\u2019ve found to generate the least instances of mortality and cardiovascular disease.\u201d
