School lunch and the "trilemma"

It's not something you would normally expect from a "just the facts" economic paper. But this ERS study on the national school lunch program lets loose with a little freestyle in the form of "trilemma." From the report:


Most issues related to the NSLP touch upon, in one way or another, two, if not all three, components of a school meal “trilemma” involving the meal’s nutrition, program cost, and student participation in the program. This trilemma applies to competitive foods as well because revenues from these foods can be important to the budgets of both the cafeteria and the school as a whole. A change to one component of the trilemma can have unintentional effects on either or both of the other components.

TK: Let's hope the "trilemma" and the aura of "competitive foods" doesn't prevent school districts from doing the right thing and implementing menus that follow dietary guidance for Americans.
