 Hunger can be considered a chronic health condition. Among children, the lack of available food to meet usual physical needs on a regular basis leads to poor cognitive and behavioral performance and is associated with adverse physical and mental health outcomes. All of these findings are well documented among poor children living in families with sufficient food and are exacerbated even more among those in families living under conditions of food insufficiency. There has been a significant effort over the past 2 decades to document the effects of mechanisms of how hunger affects learning, cognitive performance, and behavior and how a meal, such as breakfast can mitigate those effects.
