Candy Linked To Violence In Study
T Murphy writes "A study published in the British Journal of Psychiatry links daily consumption of candy at the age of 10 to an increased chance of being convicted of a violent crime by age 34. The researchers theorize the correlation comes from the way candy is given rather than the candy itself. Candy frequently given as a short-term reward can encourage impulsive behavior, which can more likely lead to violence. An alternative explanation offered by the American Dietetic Association is that the candy indicates poor diet, which hinders brain development. The scientists stress they don't imply candy should be removed from a child's diet, although they do recommend moderation. The study controls for teachers' reports of aggression and impulsivity at age 10, the child's gender, and parenting style. The study can be found here, but the full text is behind a paywall."
For an excellent overview of this story I recommend this critique of the paper from the English NHS's excellent Behind the Headlines service. Unlike a newspaper it will tell you who did the study, how it was funded, where the data came from and whether the results are worth anything. In this case the data was severaly limited and had put people into either "eating sweets every day" or "not eating sweets" which is very coarse categorising.It also doesn't report the absolute number of children who went on to become adult offenders. In conclusion
"Overall, this study on its own does not provide strong enough evidence to guide childhood dietary advice, although common sense says that eating too many sweets is probably not good for children. Before the newspapersâ(TM) explanation for a link can be believed there must be studies specifically designed to investigate the issue from the outset."
