For some years health authorities have believed that people with high blood pressure (hypertension) should restrict their salt intake. Recently scientists found in a large, well designed study that those with chronic hypertension consume less salt than do their counterparts with normal blood pressure. If it is true that a diet relatively high in salt is causally linked to the onset of hypertension, which of the following if true, most plausibly accounts for the new findings ?
