it is well-known that wine, beer and spirits can be high in calories, but it is difficult to determine the exact calories consumed because there is no nutritional label.
For the time being, it is optional for beer, wine and spirits manufacturers to label their products with nutritional information, but it may soon be a rule.
The US Alcohol and Tobacco Tax and Trade Bureau in 2007 proposed a labeling rule to require alcoholic beverage manufacturers to include calories, carbohydrates, fat and protein content on product labels.
It may be helpful for those dieting, or those who are allergic to certain ingredients. And it may serve as a reality call for many, as the label will state clearly that there is no nutritional value in many alcoholic drinks.
While red wine has polyphenols/flavonoids, beer and liquor usually don't have anything nutritional in them.
Even a single serving of wine is high in calories, as a 175ml glass has about 124 calories. That would take 25 minutes of brisk walking to burn off.
Most manufacturers oppose labeling, as it could ward off dieters and other calorie conscious people from buying their products.
Other brands, like Skinnygirl, are known for their low calorie cocktails, and would likely embrace a nutritional label.
