This advice will take you from H2O to H2-Whoa!
If you went several days without drinking water, you’d be in a world of trouble. But the idea that eight glasses a day is optimal—well, that’s soggy logic.
In 1945, The Food and Nutrition Board of the National Academy of Sciences claimed that the body needed two-and-a-half liters of water a day (which is actually ten cups of water a day, even more than the widely-referenced eight)—without citing a clinical study! Not only did people take this recommendation as fact, they also ignored the next sentence: “Most of this quantity is contained in prepared foods.”
From the looks of it, it’s clear that we’re a culture obsessed with getting those fabled eight glasses of H2O a day. In 2016, bottled water sales exceeding soda sales for the first time in recorded history, and there appears to be a new artisan bottled water brand introduced to the market daily.
