Do you know about the nutrition content of the fast food items you eat? Okay, let me rephrase that -- the 'lack' of nutrition from those foods? Although most of us eat fast food on occasion (or regularly), the calorie count can vary so widely it would boggle the mind. Think two cheeseburgers are created the same? Think again.

If you're willing to roll up your sleeves and read some startling facts about the content of those fries and shakes you may eat for lunch on a regular basis, take the quiz here and see which brands are the best (if that is possible) and which are the worst.

The answers may surprise you, but if you're going to eat fast food, you might as well make the healthiest choice you can on those products, right?
