Using any Nutrition Facts label, follow the steps below to find an estimate of how much sugar and how many calories from sugar are in your beverages.
# grams of sugar ÷ 4* = # teaspoons of sugar
# grams of sugar x 4* = # calories from sugar
Here's how those calculations work using the provided nutrition facts label as an example:
69 grams of sugar ÷ 4* = 17.25 teaspoons of sugar
69 grams of sugar x 4* = 276 calories from sugar
If the container has more than one serving, after completing the calculations above, multiply the number of teaspoons or calories by the number of servings to get the total amount in the container:
17.25 teaspoons of sugar × 2 servings = 34.5 teaspoons total of sugar
276 calories from sugar × 2 servings = 552 calories total from sugar
*Note: There are about 4.2 grams of sugar in 1 teaspoon, and 3.87 calories per gram of sugar. Rounding 4.2 and 3.87 each to 4 makes it easier to do the math, and gives you a close approximation.
