WHAT DO THE STARS EAT? Film stars are everyone's favourite subject. People love to talk about what they're wearing, who they're dating, and how much money they make. But have you ever wondered about what they eat? Chefs on film sets have the answers. "Every actor has different eating habits," says chef John Sharp. "Some stars love meat, while others are strict vegetarians who don't eat meat, eggs, or fish. Some stars love junk food, while others are constantly on a diet and eat only healthy foods." Ninety-nine per cent of the time, actresses are on a diet and insist on eating only low-fat foods. During the filming of Now and Then, Demi Moore ate nothing but Basmati rice, steamed baby spinach, green beans with lemon, and turkey sandwiches. During the filming of Twister, Helen Hunt only ate low-calorie foods, including poached eggs, dry toast, and steamed brown rice with vegetables. Other stars love to eat junk food, and never count calories during their meals. Eddie Murphy's favourite food is Kentucky Fried Chicken. Whoopi Goldberg doesn't worry about how healthy her diet is, and loves fatty bacon sandwiches with lettuce, mayonnaise and lots of butter. One thing for sure is that cooking for the stars is never easy, because they are often fussy eaters. "They want food fixed exactly the way they like it and always have something to complain about," says caterer Susan Tate. Bill Murray won't eat watermelon with seeds in it, and Mickey Rourke insists on freshly-squeezed carrot juice twice a day, but he won't drink it if it sits for more than six minutes. Cooking for the stars is hard work, but few of these caterers ever think about changing jobs. "I love my work," says Susan Tate. "Where else can I see what Michelle Pfeiffer eats for breakfast or what Al Pacino has for a snack? 1. Vegetarians don’t eat… a. junk food b. vegetables c. meat d. healthy foods 2.
