>Seed oils (used in almost everything these days) contain a lot of linoleic acid, which is a precursor to endocannabinoids, potentially giving you the munchies. If eating gives you the munchies, making you want to eat more, I'd call that a chemical addiction.
If you listen to nutrition gurus, you'll hear claims like "food X contains chemical Y and chemical Y is either itself toxic or metabolizes to something toxic, therefore you shouldn't eat X". I promise you I can find videos where somebody has found something bad about spinach and will try to convince you not to eat it. It's a bad way to reason.
Identifying individual biological pathways isn't enough to make (dietary) prescriptions. Often, the metabolites of the food aren't produced in high enough quantities to make a measurable effect (on health, or this case behavior). This kind of thing has to be studied at the level of behavior.
