Dean Edell broke the salt "news" decades ago. Apparently the misapprehension all dates back to some diet of peaches and rice (high in potassium) which helped regulate blood pressure of people with kidney disease. People have been quoting it as a fact since then. The reality is, people with healthy kidneys can excrete excess salt, and sodium/potassium balance is what is actually important. Since most people are eating processed garbage, they don't get enough potassium.
