Actually, parents are not allowed to take care of their child's lunch needs at many private schools. Lunches from home are not allowed. The private schools have been serving the low calorie, low fat and protein, high veggie and fruit, green, sustainable, locally grown lunches for a few years. I expect that the public schools will jump on the same bandwagon and ban brown bag lunches.
I don't ever see that happening. Too many allergies out there and like mine she has diabetes, I will say what she eats for lunch, not a school board. Low calorie and low fat isn't the answer, good fat is along with other healthy choices.
