Restricting children's access to foods make children consume more of those foods

"Restricting Access to Palatable Foods Affects Children's Behavioral Response, Food Selection, and Intake," by Jennifer Orlet Fisher and Leann Lipps Birch.

Although restricting children's access to certain foods may appear to encourage healthy eating, it may instead encourage overeating of the forbidden foods, according to a new study in June 1999's American Journal of Clinical Nutrition. Restricting access to any food makes that food seem more desirable to children, researchers found.
