After dragging their feet for months, McDonald's has finally caught up with their competitors. The fast food restaurant has changed the oil they use for cooking their French fries to one that's trans fat-free. Though other restaurants had already made the switch, McDonald's was worried that the change would affect the taste of their trademark fries.

A few weeks ago, my husband told me that McDonald's now offers a salt-free Big Mac. I can't find any evidence that he's right about that one, but, in any case, my response was "Why would you want to eat something like that anyway?" It's ingredients like salt, fat, and sugar that make McDonald's meals taste the way they do, and those same ingredients disguise the fact that what you're eating is ultimately junk. I can see why McDonald's was worried about the change.

Any improvement is a good one, so now when you do indulge in an order of McDonald's fries, you won't have to worry about the trans fats. But keep in mind that you do still need to worry about the fat, sodium, and calories. Learn more about healthy fast food picks with AOL Body's slide show about diet-friendly fast foods.
