Describe the bug
There is a curio in the Unique Crops mod called the Cast Iron Stomach that allows the player to eat anything assigned to the tags forge:ingots or forge:gems if you have it equipped, but not at any other time.

Backpacks will automatically feed you these items with an auto-feeding upgrade regardless of whether you have the cast iron stomach equipped or even in your inventory.

I am uncertain of whether this is an issue more closely related to Sophisticated Backpacks or Unique Crops; I do know from a TellMe dump in another modpack setting that Unique Crops apparently designates anything found in forge:ingots and forge:gems as a food item regardless of whether you're using its curio, which is probably why Sophisticated Backpacks thinks it's okay to go ahead and eat it at any time.

I'm not actually sure how you'd go about fixing this without potentially trampling on any other mod that makes items only conditionally edible(like, for example, Origins with dietary restrictions enabled), though.

To Reproduce

1. Open backpack with Unique Crops installed
2. Apply auto-feeding upgrade and ensure it is enabled
3. Put nothing but iron ingots in the backpack
4. Lose enough hunger for the backpack to feed you

Expected behavior
I would not expect to be able to eat gems and metal ingots through the backpack when I can't actually eat them manually(i.e. when the curio is not equipped).

Versions
Minecraft 1.16.5
Forge 36.2.2
Sophisticated Backpacks 3.2.4.316
Unique Crops 0.1.46
Curios 4.0.5.2

I have added a bit of code in dev to call the method that is usually called when the player tries to eat so now this is working correctly in dev.
