1) The school lunches in Hawaii are very different from those on the Mainland.  There is also a wide variation between different school districts, think of the differences between Palo Alto, CA and Detroit, MI.  What kind of food is likely to be served in those two school districts?  My lunches at Lanakila Elem were terrific on the whole, we had laulau, saimin, etc., but the pizza was lousy. When my daughter was in grade school in Northern California Bay area in some of the top school districts (Lamorinda & then Marin) and fairly wealthy areas, the lunches were so-so. The lunches at Le Jardin (private school in Kailua) (she when grad recently) were awful. Remember when ketchup was declared as a vegetable by the feds?
2) The entire nation has been getting more sedentary since people have been transitioning from physical labor to office jobs and increased TV watching & tech toys. Kids in my neighborhood (Kailua) don't play outside any more. Nothing to do with federal food or Michelle Ob
