I come from a far-off planet that is not unlike Earth, called "Wizzip". We too celebrate "breakfast" in our own ways. We even share a few of the same foods; undoubtedly they originated on my home world. "Apples," as you call them, are the major food on Wizzip, as they provide us sustenance and keep us healthy. On my world, if one does not consume a daily "waking meal," they easily fall prey to the lurking "swatinators" that roam the wilds in packs.
Now on Earth, I shall enforce the "ruling" that, indeed, an apple a day keeps the medical professional away. Breakfast must be enforced upon all for your own well being.
An apple a day keeps the doctor away, but I'm no doctor. >=).
