Just because the label says "nonalcoholic" doesn't mean you'll be getting a low-calorie beer. Nonalcoholic beer is just as high in calories as its regular-beer counterparts. Nonalcoholic beer isn't completely free of alcohol, either. A small number of calories come from the 1.5 grams of alcohol.
Breaking Down Calories
An ice-cold pint of nonalcoholic beer, which is 16 ounces, contains approximately 175 calories. Carbohydrates amount to 156 of the total calories, or 89 percent of the total calorie content. Two percent of the calories, or about 4 calories, are from a trace amount of protein. Another 3 percent of the calories, or 5 calories, are from a small amount of fat. The final 10 calories, or 6 percent of calories, are from alcohol.
Nonalcoholic beer does have at least 10 percent of your recommended amount of a few different B vitamins. Your frosty beverage provides almost 17 percent of your folate needs. Folate creates new cells all over your body. You'll even get around 10 percent of your daily choline, a vitamin that keeps your brain and nerves working. That same 16-ounce glass of nonalcoholic beer contains more than 30 percent of the niacin you need, as well as more than 15 percent of your riboflavin requirement to help your body break down food.
