The myth: Fizzy water is all the rage these days, showing up in grocery store isles in flavors ranging from coconut to watermelon. But many people worry the bubbles cause kidney stones, leach calcium from your bones, and even strip the enamel from your teeth.
Why it's bogus: The bubbly stuff is just as good for you as plain old water, Jennifer McDaniel, a registered dietitian and certified specialist in sports dietetics, told my colleague Dina Spector.
"Carbonated or sparkling water is made by dissolving carbon dioxide in water, creating carbonic acid. This process just adds bubbles — it does not add sugar, calories, or caffeine. Tonic water, club soda, and mineral water are all types of carbonated water, but these have added sodium, vitamins, or sweeteners, so it's important to read the label," Spector writes.
