ClassicHealth is a plugin that lets you allow players to play minecraft without the need of the Hunger bar. It sets the old health system for players who have the correct permissions node.
Features
Set ClassicHealth for specific groups with permissions node 'classichealth.set'
Set the amount of health to heal the player for each item
Set the worlds you want ClassicHealth to run in (Otherwise, set 'useworlds: false' if you use world-specific permissions on your server)
