AND YOU THOUGHT THE SCIENCE WAS SETTLED: “Despite a number of studies questioning the usefulness of very low-salt diets in the last few years, most major medical organizations continue to recommend them. We would assume that they do so from a strong base of evidence. But with respect to heart failure, there is a shockingly small amount of evidence.”

I’m constantly astounded at how many apparently settled items in medicine turn out to be based on weak evidence — or supposition — mindlessly repeated for many years.
