Ideally, I would want drinks to not give the player hunger at all, but a food item needs at least 1 hunger value so a saturation value can be calculated.
I have messed around with .getFodLevel, .setFoodLevel, etc., but it either adds one hunger or takes one hunger away, I could never get it to just not add any hunger.

If anyone knows or finds out how to do this, I'd appreciate letting me know!
