The staff dietitian at a doctors group says a minor-league baseball team in Grand Rapids, Mich., should warn fans that a 4,800-calorie burger it plans to sell is bad for them.

Susan Levin of the Washington-based Physicians Committee for Responsible Medicine sent a letter to the West Michigan Whitecaps yesterday. She wants the enormous burger to be labeled a "dietary disaster" that increases the risk of cancer and heart disease.

The 4-pound, $20 burger features five beef patties, five slices of cheese, nearly a cup of chili and liberal doses of salsa and corn chips - all on an 8-inch bun.
