Minecraft wiki entry for Hunger_management, associated text: A few foods also have special effects, mostly bad. While the golden apple can heal you, other foods can poison you (losing hit points), or give you food poisoning (draining your hunger bar). For these, there is milk, obtained by using a bucket on a cow. While milk doesn't restore hunger or saturation, it does wipe away any status effects that the player currently has, so use it carefully. Another option are honey bottles, which only remove poison, and do have some food value.
