My mom wasn't so much a health nut as she was against allowing her children to experience pleasure, so we didn't have candy in the house and we ended up idolizing the sugar-based crack like addicts and sneaking it in when she wasn't looking.
But I'm thinking that making a gumball machine out of a dead person's withered head and leaving it in the living room might have worked a lot better than telling us that candy was bad.
In fact, had she zombified all the no-no foods I might have learned that one doesn't need to eat a can of frosting for dinner just because it was there and instead I could have had a salad or something and lived a much healthier life.
