Hunger

Hunger is the amount of time left until the player starts losing health because the player didn't eat, resulting in a slow death.

Starvation
The player may lose health because the player's hunger bar has depleted. When this happens, the player loses 1 HP over time. The only way to counteract this is by eating regularly and thus not letting the hunger bar deplete.

Eating
For a list of all food items available in the game, see Category:Food.

Since it may be of one's interest not to die, one may eat food that may be collected from the world, dropped by enemies or animals, farmed, or fished. Every food refills a certain amount of hunger, which is indicated in the tool-tip.
