Elimination Diets and ADHD continued...

Sugar and ADHD

Some children do become hyperactive after eating candy or other sugary foods. No evidence indicates, however, that this is a cause of ADHD. For best overall nutrition, sugary foods should be a small part of anyone's diet, though there is probably not much harm for a child or adult with ADHD to try eliminating sugary foods to see if symptoms improve.

Caffeine and ADHD

Some studies have shown that small amounts of caffeine may help with some ADHD symptoms in children. However, the side effects of caffeine may outweigh any potential benefit. Most ADHD experts recommend minimizing or avoiding caffeine.
