CRYSTAL CRUISES said it has gone trans fat-free on its two ships. The line said its chefs have replaced all trans-fat oils with trans-fat-free oils, such as sesame seed oil, pumpkin seed oil and different olive oils, in its restaurants and in its crew galleys. Toni Neumeister, Crystal vice president of food and beverage operations, said the line's "priority in this initiative is to offer healthy food choices."
