Would you use sodium, a caustic alkali, to season
your food? Or chlorine, a poisonous gas? “Ridiculous
questions,” you say. “Nobody would be foolhardy
enough to do that.” Of course not. But the shocking
truth is that most people do just that because they don’t
know that these powerful chemicals constitute the
inorganic crystalline compound known as salt. For
centuries, the expression “salt of the earth” has been
used to designate something good and essential. This
idea is erroneous! Salt may actually help to bury you!
