MINECRAFT 1.8 IS GO!

[The Eupho Guy_v1legacy]

As people have said numerous times, you need to eat to remain "healthy". I don't know what happens if you starve, I have yet to. You do move slower and don't regenerate (at all or as fast, again, not 100% sure, I keep myself well fed =P) if you get hungry. Food doesn't heal you.

You lose health. I am playing on Normal and didn't eat and ended up losing all but half a bar of health. Not sure if difficulty changes how much you lose.
