"Is Salt Really So Bad? Experts Disagree About Its Role in High Blood Pressure"
By Salynn Boyles:
Sept. 25, 2003 -- If you have high blood pressure, you've probably been told to reduce the salt in your diet, but new findings are challenging the idea that sodium is a major culprit in promoting high blood pressure.
Researchers who have argued against the salt-blood pressure link for almost two decades presented new data Thursday suggesting that high blood pressure is much more closely linked to a diet low in minerals such as calcium, potassium, and magnesium than sodium intake. The data were presented at the American Heart Association's (AHA) 57th annual high blood pressure research conference in Washington, D.C.
In the newly reported study, roughly 33,000 people had their blood pressures recorded.
Researchers divided the participants' sodium, calcium, and total mineral intake into four groups and found that while blood pressure did not vary significantly according to sodium intake, higher calcium intake was associated with lower blood pressure. In one of the most recent surveys, higher mineral intake was also linked to lower blood pressure.

Dr. David McCarron, MD:
The data indicate that it is not the sodium per se that affects blood pressure, but the lack of calcium, magnesium, potassium, and probably some other minerals and vitamins.
