If you don’t want your kid to grow up to be violent, don’t feed him (or her) sweets and chocolate every day.
A recent study found that 10-year-olds who ate sweets daily were much more likely to have a violence conviction by age 34. The researchers suggested that this might be because they hadn’t learned to delay gratification.
BBC News quotes researcher Simon Moore as saying, “We are fairly confident that this is a realistic relationship, the key is explaining what the mechanism is behind this relationship. We think that rewarding bad behavior in childhood with confectionary can lead to later problems but we need to look at this more closely.”
