The first 6 months of the study constituted a baseline period, followed by a 10-month experimental stage, and finally a 6-month return-to-baseline program. A comparison of 28 juveniles who experienced both diets resulted in a 35 percent lower incidence of antisocial behavior when they were on a low sugar diet. The long-term offenders who experienced the low sugar diet showed a 45 percent lower incidence of antisocial behavior than the juveniles who were previously or subsequently incarcerated and who consumed the original diet. The main diet revisions involved the replacement of soft drinks and junk food with fruit juices and healthy snacks as well as the elimination of high sugar content desserts and cereals. Tables and 10 references are supplied. (Author abstract modified)
