Healthy Snack List In accordance with federal law, P-O supports and promotes initiatives that encourage healthy eating habits among students. The following is the district's healthy snack list, which details the types of snack foods that can be eaten during school hours. The list is not all-inclusive but exists to serve as a guideline for parents and guardians. Parents, teachers, staff and community members who have questions about the district's healthy snack list should contact the school nurse or another member of P-O's school health council.
