A new eight year long European study concludes that salt consumption is not dangerous and may in fact be beneficial. This is certainly contrary to advice from American Medical Association, American Heart Association and the Center for Disease Control and Prevention, which says higher sodium consumption can increase the risk of heart disease. It's not unusual to see differing opinions, but what are we ordinary folks to make of the controversy?
The study followed 3,681 middle-aged Europeans who did not have high blood pressure or heart disease at the start of the study. They were divided into three groups: low salt; moderate salt; and high salt consumption. There were 50 deaths in the low salt group, 24 in the moderate consumption group and only 10 in the high consumption group. In fact, the heart disease risk in the low consumption group was 56% higher in the low salt group. What they concluded was that the less salt the participants ate, the more likely they would die from heart disease.
"The optimal level of salt in our diets has been a controversial subject for at least 20 years," say co-authors Dian Griesel, Ph.D. and Tom Griesel of the new book, TurboCharged: Accelerate Your Fat Burning Metabolism, Get Lean Fast and Leave Diet and Exercise Rules in the Dust (BSH, 2011). The problem they say generally boils down to the effect (or lack thereof) salt has on blood pressure.
"There is no disagreement that high blood pressure (even moderately high) is a risk factor for heart disease and stroke," say the Griesels. "However, salt consumption does not seem to have the same effect on everyone. In addition, there is usually no distinction on the type of salt used. There are many naturally harvested salts that also contain many trace minerals, which undoubtedly have an effect. Medical literature on salt consumption (like many other things) is inconsistent."
