Currently, as a Piglin, you are unable to eat any porkchops to restore health, even though piglins can eat raw and cooked porkchops (as shown by the items not dropping when they are killed).

• When you eat a Raw Porkchop as a Piglin, you should be healed by 3 HP.
• When you eat a Cooked Porkchop as a Piglin, you should be healed by 3-8 HP. (the latter value can be overpowered as Piglins only have 16 max HP)
