Thanks all for the replies!

Great stuff!
The main reason I asked the question is, like I said, I work with children, and I can't help but think that a lot of the wild behavior and "behavioral disorders" that kids have is due to what they eat.
I feel kind of bad putting a kid in time out when they were just fed that processed, sugar-filled snack.
Of course, kids will be kids, but diet I think plays a big role.
I don't know what the Standard Australian Diet is for kids, but kids here in America pretty much eat nothing but junk.
And it breaks my heart.
Anyone else with some stories to share, that'd be great!
