The biggest junk science of 2018

7. Raw Water Became a Trend. Another year, another absurd health fad, although 2018’s was particularly egregious. At a time where at least half a billion people worldwide lack access to a basic drinking water service, numerous companies in the United States are now selling “raw,” “naturally probiotic,” untreated water. But what they call probiotic, scientists call potentially contaminated with parasites and animal poop. There are no health benefits to drinking so-called “raw” water. It will, however, lighten your wallet significantly more than simply drinking tap water.
