How to inform parents when snacks are forbidden in school?

Please note that the school prohibits bringing snacks to parents:

Dear parents of students:

We warmly inform you that students are forbidden to bring snacks to school. Eating snacks during school is not only bad for students' health, but also has an impact on other students, thus interfering with the teaching order and the attention of other students.

Therefore, I hope that parents will cooperate with our work, do not provide snacks to students, and supervise and inspect their children.

Thank you parents.

Xxx school.
