If you think too hard about any kind of food, it can start to get weird.

Like coffee. You're taking the fruit of some tropical plant, ripping off the berry-flesh part that it wants mammals to eat, taking the seed that it wants those mammals to poop out somewhere else, killing it with heat to produce different flavor molecules, crushing it to powder, then passing hot water or steam through the powder to leach out those flavor molecules, including the molecules that the plant uses as a defense against improper eating. On top of that, adding things like the fat skimmed off the mammary secretions of other species, highly processed molecules from a temperate grass modified to produce gigantic seeds full of starch, and crystals from the juice of pulverized stems of tropical grass. This is poured into a vessel formed from huge trees pulverized down to loose cellulose fibers and molecules created using organic reactions from crude petroleum, or maybe just those organic polymers, puffed up with air.

It could be all that insane-sounding stuff, or it could just be a cup of coffee.

It is sort of cool that humans can't digest grass, but they grow grass anyway, so they can feed it to animals that can digest grass and then turn it into proteins and nutrients that humans can harvest from the animal without killing it, and which is tastier and more nutritious than raw grass juice.
