Braceface (2001)

Season 3: Episode 25

Sharon's wiped from eating badly between exams and homework. The doctor tells her she's anemic and needs more iron in her diet. He suggests she go back to eating meat and Sharon is horrified. Vegetarianism is very important to her! And the only one who seems to understand is Cody, a great guy that Sharon has just met. Even though he's a meat-eater, he's totally sympathetic to her problem - until Sharon finds out he isn't as honest as he appears to be.
