I think you need to rethink what you took from the piece, because:
"These are extremely important findings for those who are suffering from high blood pressure," said Andrew Mente, lead author of the study, a principal investigator of PHRI and an associate professor of clinical epidemiology and biostatistics at McMaster's Michael G. DeGroote School of Medicine.
"While our data highlights the importance of reducing high salt intake in people with hypertension, it does not support reducing salt intake to low levels.
"Our findings are important because they show that lowering sodium is best targeted at those with hypertension who also consume high sodium diets."
What you need to bear in mind is that MOST Americans already have a high salt intake - salt's in almost everything we eat that is baked or cooked. Right now, I do use "lite salt"...but I also know that with the other foods I eat, my sodium intake is probably at least the "normal" level, if not still higher than what it should be. A true "low sodium" diet, on the other hand, is one that restricts one's intake to almost no restaurant or fast-food or frozen meals, and consists mostly of veggies, fruits, and meats that one cooks oneself using salt substitutes like potassium chloride. Just to let you know, I can make really good no-sodium salsa and guac....
