A substance often found in soft drinks is caffeine, which helps to make people feel .
Doctor Suglia suggests that caffeine could be causing the 5-year-olds to be more aggressive. The research is part of a large study called the Fragile Families and Child Wellbeing Study, it follows 5,000 poor mothers and their children in 20 American cities.
Earlier studies of young adults have found the highest sugar levels in those who carry weapons and show signs of negative social behaviors.
