Is Salt Nature's Antidepressant?
March 31, 2009
Many people consume too much salt, but new research may have uncovered one reason people crave it -- it might lead to a better mood.
Researchers found that when rats are deficient in sodium chloride (common table salt), they shy away from activities they normally enjoy. A loss of pleasure in normally pleasing activities is one of the most important features of psychological depression.
If salt is a natural mood-elevating substance, it could help explain why so many are tempted to over-ingest it, even though it's known to contribute to high blood pressure, heart disease and other health problems.
