I bet you didn't know this?
by Dr. David Brownstein
An article in The Journal of The American Medical Association (May 4, 2011. Vol. 305, N. 17) looked at the influence dietary salt had in cardiovascular disease. The authors studied 3681 subjects for a median of 7.9 years. What the researchers found made headlines in major newspapers.
The scientists reported that there was a direct, inverse linear correlation between the amount of salt ingested and the rate of cardiovascular deaths. What that means is that as salt intake went up, cardiovascular deaths went down. They stratified the subjects into three groups; a low, medium and high salt intake group. The death rates declined as the subjects ate more salt: from 4.1% in the lowest group to 1.9% in the medium group and 0.8% in the highest group.
For those who have read my book, Salt Your Way to Health, there really wasn’t anything new in this study. However, the media (at MSNBC.com) had large headlines proclaiming, “Eating less salt doesn’t cut heart risks.” However, MSNBC missed it here. The headline should have read, “Eating less salt increases your cardiovascular death rate over 5x as compared to those who eat a high salt diet...”
