Fast food restaurants have been changing their recipes to adapt to New York City's trans fat ban. Here are some of the menu overhauls at major chains:

-Dunkin Donuts: Quit using partially hydrogenated oil months ago in favor of a trans-fat-free blend of palm, soybean and cottonseed oil.

-Kentucky Fried Chicken: Ditched trans fats from cooking oil immediately, recently removed it from its pot pie and biscuits.

-Pizza Hut: Removed trans fat from the one style of pizza that had it.

-McDonald's: Stopped cooking fries in trans fat last year, and now has it out of cookies and baked apple pie too, at least in New York. The rest of the country will follow.

-Burger King: New York locations no longer use trans fat in fries, apple pie or biscuits, with plans to eliminate them nationwide.

-Boston Market: Testing a trans-fat-free version of its chicken pot pie and cornbread in New York. If all goes well, the recipe change will be expanded nationwide.
