It would be helpful for someone conducting research before writing a persuasive essay supporting the claim that schools should improve the nutritional value of lunches served at school to consult a source from a reputable health or nutrition organization.

1. Centers for Disease Control and Prevention (CDC): The CDC provides a wide range of information on nutrition, obesity, and healthy eating initiatives in schools. They offer data on the impact of improved nutrition on student health and academic performance.

2. American Academy of Pediatrics (AAP): The AAP focuses on the health and well-being of children and provides evidence-based recommendations on various topics, including nutrition. Their expertise can provide valuable insights into the impact of school lunches on children's health.

3. American Heart Association (AHA): The AHA is focused on cardiovascular health and offers guidance on healthy eating, including recommendations for schools. They provide resources on the importance of proper nutrition in reducing the risk of heart disease and other health issues.

These sources are likely to provide comprehensive and reliable information on the nutritional value of school lunches and the potential benefits of improving them.
