THE INTERNET IS A CORNUCOPIA OF facts, some true and some “alternative” (in other words, lies). One topic that is particularly plagued by misinformation is pH. People are restricting their diet, buying alkaline water, testing their urine with pH test strips, and buying into bogus cancer cures, all on the basis of false pseudoscientific claims. Going back to basics will help us distinguish pHacts from pHiction.
