The roommate tipped me off to a new blog in the US called Fed Up With School Lunch. An anonymous teacher in the midwest, Mrs. Q, is eating her public school's school lunch and secretly taking photos each day to show people what American kids are eating these days. I think this is a really great blog and am surprised that something like this hasn't popped up earlier. I just wrote about Japanese school lunch, which in contrast, is applauded (well...with the exception of whale meat which is sometimes found in parts of Japan) and hailed for its accessibility and focus on nutritional education.
Check out Mrs. Q's blog if you have a chance!
