Drinking sugar-filled drinks can impact the behavior and math scores of preschool children. In a study published in the journal Health Economics, researchers studied over 450 children who consumed either sugary drinks or artificially sweetened drinks. While the behavior of young girls was not affected, consuming one sugary drink tended to induce an initial ‘relaxing’ effect for boys, before making them more restless. Consuming one sugary drink also had a negative impact on student achievement scores in math for boys.
