A long, but excellent article by NYT fitness writer Gina Kolata (a serious strength training enthusiast, by the way), which contains a rare admission of relative ignorance from academic clinicians (see quote below): that they and their preening, condescending colleagues appear to not really understand as much as we claim to about sodium metabolism.

Now, this does not mean that you should start dumping salt on your food. It does mean, however, that you should become more sensitive and skeptical about what is supposedly settled science.

“The work suggests that we really do not understand the effect of sodium chloride on the body,” said Dr. Hoenig.

“These effects may be far more complex and far-reaching than the relatively simple laws that dictate movement of fluid, based on pressures and particles.”

She and others have not abandoned their conviction that high-salt diets can raise blood pressure in some people.

But now, Dr. Hoenig said, “I suspect that when it comes to the adverse effects of high sodium intake, we are right for all the wrong reasons.”
