In general, if these programs are offered, and you agree with the mission statement, but you are not in need of them (e.g., you're well off enough/not food insecure)
use them anyway! You're not taking away from those in need, you're showing that this is a real need and should be funded. In addition, you're helping to destigmatize the program; if the kid who gets dropped off in a ratty minivan eats the same food as little Timmy who got dropped off in his parents' 911, that's probably (depending on your worldview...) a good thing.
