I invite you to try this at home: Go into your kitchen and spoon ten teaspoons of sugar into a bowl. Would you ever sit down to eat this much sugar, all at once? Probably not. But if you drink sugar-containing beverages—soft drinks, sweetened iced teas, energy drinks, sports drinks, smoothies, even fruit juice—you can easily consume that much sugar or more in just a few gulps. A 12 ounce can of Coca Cola has 10 teaspoons of sugar in it, about the same as a 12 ounce bottle of 100% orange juice. Grape juice has even more—about 15 teaspoons of sugar in 12 ounces.
