It’s pretty hard to fit an alcoholic beverage into a nutritional plan, since alcohol producers have long been resistance to using the nutritional labels standard to most of the food & beverage industry. Finally, the maker of Guinness, Captain Morgan, Johnnie Walker, and others has announced that they will fall in line with nutritional information practices. So here’s a preview of what you’ll soon find out.
First of all, alcohol contains 7 calories per gram. Compare that to 9 for fat, and 4 for protein or carbohydrates. Almost all of the calories in liquors come from their alcoholic content. The higher the alcohol content, the more calories. As for drinks like Bailey’s or Kahlua, which contain added cream, dairy and (probably) added sugar, a shot can contain around 10.6 grams of carbohydrate, 1.3 grams of protein, and 6.2 grams of fat.
The same alcohol=calories format is true for beer. A 12-ounce can of Guinness (4.2% alcohol by volume) has 128 calories, while the same amount of Budweiser, at 5% alcohol, is 145 calories. Both beers include 10.6 grams of carbohydrate, and negligible amounts of protein (1.1 and 1.3 grams respectively).
