negative behaviour dropped the most from vitamins, 35%
Virkkunen et al -
found violent offenders had lower serotonin levels, than average
can be treated by a diet including salmon or tuna as it is rich in serotonin
Schoenthaler -
found a reduced sugar diet could reduce anti-social behaviour by 48%.
Vitamin B3 has been used to treat some forms of schizophrenia, a disorder associated with violent crimes.
Removing certain artificial colourings, from children’s diets can have an effect on hyperactivity (which can
lead to crime in adult life).
