You'll get a satisfying crunch with fewer calories and more nutrients.

But a large order of fries can have as many calories as a burger -- about 500 at a typical fast food restaurant. Better Bet: Opt for a side salad or fruit cup, if available. Or if you have willpower of steel, go ahead and order fries but limit yourself to five or six.

It has less fat than a typical candy bar and may be good for the heart.
