"What parent hasn't used candy to pacify a cranky child or head off a brewing tantrum? When reasoning, threats and time-outs fail, a sugary treat often does the trick. But while that chocolate-covered balm may be highly effective in the short term, say British scientists, it may be setting youngsters up for problem behavior later. According to a new study, kids who eat too many treats at a young age risk becoming violent in adulthood.

The research was led by Simon Moore, a senior lecturer in Violence and Society Research at Cardiff University in the U.K., who specializes in the study of vulnerable youngsters. Moore had been investigating the factors that lead children to commit serious crimes, when, during the course of his work, he discovered that "kids with the worst problems tend to be impulsive risk takers, and that these kids had terrible diets — breakfast was a Coke and a bag of chips," he says."
