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."

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."

    Just a theory. And one way of many. But I've seen it too often, that a addiction, being itself a replacement for something else you need, does mean that when you don't get it, you become desperate and do things that you normally would not do. Not specifically violence. More like when you destroy everything around you because you can't stand the situation. (Similar to rage.)

    We should be clear about those two things:
    1. Candy is a likely candidate for addictions.
    2. Addictions always are a replacement for a lack of something else.
    So find that something else, and help the person get that stuff so much, that they forget the addiction because they don't need it anymore.

So far, he likes "good food." It helps that his mother actually cooks at home and has always made his babyfood from scratch since he was introduced to foods in the first place. I guess it is what he is used to. But if I were to asked what his absolute favorite food was? It would have to be any kind of meat and bacon in particular. I know THAT can't be too healthy.

    To be clear, I eat cookies and candies and ice cream at least once or twice a week if not more at times. I always offer these things to him nearly every time.

And while he is uncontrollably curious and shows strong indication of being rather analytical, he doesn't have any real behavior problems at all... there were no "terrible twos" though his assertiveness seems to be building more and more lately but still nothing compared to what I have seen in other, more typical children.

However, increasingly, the field of psychology has been becoming more scientific and following more scientific principles.

Petrochemical food additives such as artificial coloring (FD&C anything), flavoring and preservatives (BHA, BHT, some others) are inherently toxic and immune response to them varies wildly between individuals. With some people you'll never notice a difference. With others, the tiniest bit of, say, red dye will make them hyper, violent, you name it.

    Keeping synthetics out of your diet can be difficult. It helps if there's a nearby Whole Foods Market or similar store that bans all synthetics. There is NO REASON for synthetics in food other than that they save food processors from having to buy real ingredients.

(We even see this in the human workplace, where the underlings' labour brings in a profit, which the owner then graciously shares with them as wages.)

    But if the master gives the dog a food reward, a dog that really wants to please becomes confused ("Huh?? I thought YOU were the master, now you're saying *I* am? WTF??") and often will refuse to even take the "reward" (unless starved for several days first, and yes, some food-based trainers DO keep their dogs half-starved, to ensure that the food-reward will be accepted).
