Yesterday, I stopped at a convenience store to buy something to drink. I was lured by a “Vitamin Water” label that proclaimed that the drink had “Zero Calories.” So, I bought it and drank it down.
Then, after I finished I checked the label. It indeed said that it was zero calories, but also said that it had 6 grams of carbs per service. Unfortunately, there was 2.5 servings in the 16 ounce bottle I gulped down – or 15 grams of carbs in a couple of gulps.
How can this be? I thought that all carbs have calories (I read elsewhere that there were 3.7 calories per carb gram). If Vitamin Water does indeed have 6 grams of carbs per serving, doesn’t it contain calories by definition?
