A looming trans fat ban in Chelsea is leaving one local baker wondering how his turnovers are responsible for the obesity epidemic and wishing the government would keep its hands off his dough

At Katz's Bagel Bakery, a Chelsea fixture since 1938, the bagels have always been the big draw, but owner Richard Katz also does a brisk business with pastries like turnovers and whoopie pies, pastries that he makes with partially hydrogenated vegetable shortening.

That shortening will be banned on Jan. 1, leaving Katz vowing to stop selling pastries rather than peddle what he calls "awful" tasting trans fat-free baked goods.
