at my sons school they don't have a cafeteria. the lunch is from a different fast food place each day....i was the only voice concerned with this on a recent survey. fried chicken, hot dogs, pizza and maybe a sub are the typical meals. of course you don't HAVE to use these lunches but it doesn't make it easy to support healthy meals for kids.
i am a bit of a health food nut and love shopping at our co-op, i also love a burger! it does seem to me that there are systems issues in our culture that support over consumption of goods and food and would love to see that shift. TV and sedentary lifestyle seem a big part of it too.
