Minecraft wiki entry for Hunger_management, associated text: Disadvantages:
Require 8 gold ingots to be crafted, meaning that they are too expensive to be an efficient food source in survival mode, unless with an efficient gold (zombified piglin) farm
Eating them takes a few seconds, while splash potions or lingering potions of Healing can be instantly applied by throwing them.
Finding them in structures (dungeon, mineshaft, igloo, stronghold, underwater ruins, desert pyramid, woodland mansion, ruined portal, bastion remnant) chests is rare and unreliable.
