I created my own behavior pack, and in this behavior pack I created my own type of cake and for the cake to saturate you I had to use the "minecraft: on_interact" component and an event in which I added the command "effect @e [type = player] saturation 1 1 true" and everything before 1.17.30 worked fine, so after eating a cake, one hunger recovered, but now after 1.17.30, after eating one piece of cake (a cake made by me), the whole bar replenishes immediately, and it shouldn't work that way. In my opinion, the fault is on your side, not mine, because everything worked fine before version 1.17.30.

On Minecraft 1.17.10, everything worked fine.
