It's pretty heavy tasting, so you might be concerned about how many calories a Guinness or two will be adding to your St. Paddy's Day calorie count.
Fear not! Science is here to provide you with the facts you need to make a level-headed decision, like it does for many emotionally-driven concerns.
Scientific fact: 12 ounces of Guinness Draught contains 126 calories. That's only 16 more than a Bud Light.
And it's 42 fewer than the same amount of fresh-squeezed orange juice!
Get out there and enjoy yourself this St. Patrick's Day!
