With 1st hand experience mentoring incarcerated youth for several years, I've witnessed the lack of nutrition, hunger and desperation that leads to behavioral problems.
Children who live in food-insecure homes are more agitated, likely to get sick, have a harder time recovering from sickness and experience behavior problems. If the proper amount of food is not provided they experience trouble concentrating in school and may misbehave more often or have emotional challenges, which may lead to detention and/or entry into the criminal system.
