Beta Auto Eat
Purpose
There are a myriad of auto-eating mods available for modern versions, which use the modern hunger mechanics... But become unusable if you're using mods or server plugins to emulate Beta 1.7.3 (and prior) food mechanics.
This mod solves that by eating food based on your current health, rather than your current hunger.
Disclaimer
Use at your own risk. Some servers may consider this mod an unfair advantage (cheating.)
Ask the server's staff team prior to using this mod in multiplayer.
