MUKWONAGO, Wis. (AP) -- Students at a southeastern Wisconsin high school are boycotting cafeteria food over what they say is a federally-mandated one-size-fits-all approach to nutrition.

School districts across the country have revised lunch menus to meet federal requirements for more fruits, vegetables and whole grains.

Nick Blohm is a 210-pound linebacker on the Mukwonago High School football team. Blohm says the 850-calorie cap on his school lunch isn't enough for him. He gets hungry before three hours of football practice.

About 70 percent of the 830 Mukwonago students who normally buy lunch, boycotted it Monday. The school district's food service supervisor Pam Harris tells the Journal Sentinel poor nutrition is a serious problem in America, but the mandated changes are too abrupt. She says what students eat at home is also a big piece of the puzzle.
