Not a cure by any means, by several swear by it as a preventative for all
that ails you. I've added a teaspoon in V8 to my morning regimen. It's
pretty invigorating.

Any acidic foods do, including soda pop, citrus juice, etc. The biggest
threat is overall duration of exposure, rather than quantity, so if
you're going to drink or eat acidic stuff, get it down and out of your
mouth. People who suck sodas all day are doing themselves no favor even
if it's diet pop.
