The investigators hypothesize that fiber supplementation will provide measurable differences in indices of children's health (fewer complaints of abdominal pain and constipation, lower body mass index) compared to placebo.
This prospective study proposes supplementing children with fiber or placebo for four months. Children in elementary school, ages 5-12, will be randomized to receive fiber supplemented bars vs low-fiber snack bars (placebo).
