Real Simple has an article showing how small ordering choices can make fast food healthier. Not healthy. Just a little less like eating nuclear weapons for lunch. The highlight:

Fast-Food Chain:
McDonald's

If You Usually Order:
Six-piece Chicken McNuggets (with a side of ranch sauce) and large French fries.

Make It Healthier:
Ask for medium fries and replace the ranch sauce with barbecue and you've knocked 345 calories off your meal.
