New York City's board of health voted yesterday to ban the use of trans fat in all of its 24,000 restaurants. Estimating it will save hundreds of lives per year, the board is giving chefs 18 months to find suitable replacement oils for all their frying needs.

The New York ban may have nationwide implications, according to experts, because chains ranging from McDonald's (NYSE:MCD) to Wendy's (NYSE:WEN) to Yum Brands' (NYSE:YUM) KFC may find it easier to standardize on one method of cooking. Many of these either have plans to (or already have) cut back on the trans fat in their food.

Emboldened by this initiative, might New York officials be considering other measures as well?
