We are defnitely seeing the effect as childhood obesity becomes a national concern. The federal and state (Texas) rules about what can be served on campus during school hours affect all our organizations. No possible way to serve donuts or provide a sweet snack (except on one of the 3 days the school requests as exceptions for holiday parties and celebrations.)
Every district here has a wellness committee comprised of parents, staff, community members that explore issues and recommend policy. One of the issues is restrictions of types of food served on district property ANY time.
I served on that committee this year. The policy we put in to place will effect fundraising, concession stands, bake sales, school dances, after school clubs -you name it. There were those who those thought we should set restrictions on portion size, fat content, sugar, etc. We went with a much more open policy requiring organizations to serve at least one healthy option (when feasible), to consider the inclusion of healthy foods in th planning stage, and to encourage non-food fundraisers.
During our research phase, we did find many districts across the nation are banning school-affiliated organizations from selling candy, cookie dough, etc. I personally think that's overkill. But some ARE doing it.
Here's the thread where I posted the final policy:
