Alcohol, glucose and violent crime

There is a strong link between alcohol intoxication and violent crime but not everyone who drinks becomes aggressive or violent. A Finnish study of 89 people compared impulsive, violent, antisocial male offenders to a non-offending control group. The participants' glycogen levels (which are connected to glucose metabolism) were measured at the start of the study and the participants were followed for eight years to see whether they committed any violent crime. 17 of the offenders re-offended over the course of the study and the average glycogen levels of these people were much lower than in those participants who stayed out of trouble.
