LOS ANGELES—It's lunchtime at Washington Preparatory High School in Los Angeles, but 16-year-old Parrish Jackson has barely touched her turkey burger and apricots.
She's dumping them into the trash can.
The apricots are "sour," the junior says. The meat is "nasty." If it were up to her, she would just have taken the potato wedges — they're close enough to fries — then headed to the student store to fuel up on hot Cheetos and juice.
