It is a very misinformed doctor or nutritionist that would suggest eliminating salt from the diet has any bearing on lowering blood pressure or reducing the risk of heart attack in this day and age. Yet almost with monotonous regularity we are exhorted to reduce salt consumption by perhaps well meaning government sponsored doctors and nutritionists who haven't even bothered to read the in-depth research on this subject.
It is typical of the dogma that surrounds the medical fraternity. If they are determined to "prove" a point they will selectively gather data so they are shown to be right and to hell with the real results. As long as their position is vindicated then they have justified their existence.
Of course most studies are funded by vested interests with a financial interest in the results. So what scientist is going shoot themselves in both feet at once by coming up with a finding completely opposite to what he is being paid to find?
It's too easy to put a pair of blinkers on and focus on just one aspect of a particular problem without looking at the whole! Holistic healers look at the person as a whole - never seeking to isolate a single symptom and treat it with allopathic drugs and chemicals. High blood pressure is invariably caused by many other factors other than salt!
