Grain Of Salt

Doctors may start prescribing a grain of salt to be taken with any medical research you read or hear about.

The Journal of the American Medical Association has published a study that shows one-third of all major medical studies (eg. the benefits or dangers of this drug or that vitamin) were contradicted by subsequent research.

The lesson, of course, is to be a healthy skeptic if you want to stay healthy. And, no matter how credible the source, always question the results of "a recent study".

Including this one.
