They simply compared eating breakfast to not eating breakfast and nothing more. Kids did better when they ate as opposed to not eating. The results speak for themselves.

You said, "School is not there to make sure children eat, it is there to educate!"

If making sure kids are fed helps them in the classroom, and it does, I consider it to be a vital part of education based on the science.

"Could then wake up in time to eat bkfst and catch the bus."

For one example...Parent is gone to work or has not come home yet. 

Not sure why folks are angry about having to feed kids. Whether it be school or anywhere else. They are kids, and should not suffer from starvation and malnourishment. I can hardly think when I am hungry. I get really cranky too. Just ask my kids. I ain't fit to be around.

The "irresponsible parent" argument is irrelevant. It's science solely focussed on kids fed or not fed breakfast.

"Wonder if..." is no way to win a debate.
