(NPR) - When it comes to tallying our liquid calories, we're not always so accurate. Does that tiny 5-ounce serving of wine really count as a glass of wine? (The answer is yes.) So as the season of celebrations heats up, and holiday cheer is delivered in the form of bubbly, beer or booze, just how many calories are we consuming from alcohol on a random Tuesday night? Almost as much as we get from soda, apparently — an average of about 100 calories a day. That may not sound like a lot, but it can add up. A new Centers for Disease Control and Prevention analysis provides some more insights into the nation's drinking habits.
