Calorie-wise, you may be tempted to grab a light lager, but for health benefits, a dark beer is the better choice. Dark beers tend to have the most antioxidants, which help reverse cellular damage that occurs naturally in the body.
Just as you can't judge a book by its cover, you can't judge a beers strength by its color. Although many people assume that darker beers have a higher alcohol content than lighter beers, the truth is that a beer's color has nothing to do with its strength.
A light beer has less alcohol per volume and calories than a dark beer. With a light beer, the color and flavor is lighter. Also, light beers are usually more refreshing and less filling. When it comes to dark beer, it has a much fuller flavor.
