A minor league baseball team is offering a 4,800-calorie burger that has been labeled by doctors as a "dietary disaster." The $20 burger weighs four pounds and features five beef patties, five slices of cheese, nearly a cup of chili and liberal doses of salsa and corn chips on an 8-inch bun. Dietitian Susan Levin of the Physicians Committee for Responsible Medicine sent a letter to the West Michigan Whitecaps on Tuesday. She wants the burger to be labeled a "dietary disaster" that increases the risk of cancer and heart disease.
