School should improve the nutritional value of lunches serve at school, which source would provide the most relevant information for someone conducting research before writing a persuasive, essay supporting this claim

The U.S. Department of Agriculture (USDA) would be one of the most relevant sources for someone conducting research before writing a persuasive essay supporting the claim that schools should improve the nutritional value of lunches. The USDA oversees the National School Lunch Program (NSLP), which sets nutritional standards for school meals in the United States. They have extensive research, guidelines, and resources available on their website regarding school meals and nutrition standards. Additionally, the Centers for Disease Control and Prevention (CDC) and American Academy of Pediatrics (AAP) also provide valuable information and research on this topic.
