Correct me if I’m wrong, but I believe this particular ice is made from a chemical called dihydrogen monoxide (H2O), which we colloquially and collectively know as a liquid called water. While water is necessary to our survival, it has no nutritional value. Being a liquid, water is also something we drink rather than chew. It therefore does not fall under the strict definition of food.
On the other hand, frozen water must be either held in the mouth (or in a hand, or in a bowl) until thawed, or it must be chewed. Something that is chewed would indeed be classified as food. However, would we cover it in sauce or gravy and eat it with a fork (quickly, before it melts, at which point it would no longer be food)? Would we fry it with some peppers and onions and slather it on a sammich? Didn’t think so.
Still, the controversy rages on.
This bag I recently purchased has another brilliant statement — no doubt put there by their attorneys in response to their perceived dumbing down of humanity. Besides, what if I just wanted some regular water later?
