Children who eat sweets and chocolate every day are more likely to be violent as adults, according to new research.
A study of almost 17,500 participants in the 1970 British Cohort Study found that 10-year-olds who ate sweets daily were significantly more likely to have been convicted for violence at age 34.
Science Daily reports that the study, published in the October issue of the British Journal of Psychiatry, is the first to examine the long-term effects of childhood diet on adult violence.
Researchers from Cardiff University found that 69 percent of the participants who were violent at the age of 34 had eaten sweets and chocolate nearly every day during childhood, compared to 42 percent who were non-violent.
This link between confectionary consumption and violence remained after controlling for other factors.
The researchers put forward several explanations for the link. “Our favored explanation is that giving children sweets and chocolate regularly may stop them learning how to wait to obtain something they want. Not being able to defer gratification may push them towards more impulsive behavior, which is strongly associated with delinquency,” said lead researcher Dr. Simon Moore.
The researchers concluded: “This association between confectionary consumption and violence needs further attention. Targeting resources at improving children’s diet may improve health and reduce aggression.”
