Burger King tries non trans fat

Miami, Florida - Burger King says it's testing cooking oils without trans fats in its fast food restaurants.

The world's second-largest burger chain says it has been working for more than two years to identify oils without the artery-clogging substance for eventual use in its 7,500 restaurants in the United States and Canada.

The Miami-based company says it will secure commitments from its suppliers for the alternative oils, after in-restaurant testing is complete.

The company plans its national rollout in late 2008.

Burger King's move follows one by McDonald's, the world's largest burger chain, and other fast food chains to shift to trans-fat-free oil.

Amy Winterfeld of the National Conference of State Legislatures says Florida is one of at least eleven states that have proposed bills in 2007 to ban or restrict the use of trans fats in restaurants or school cafeterias.
