Hunger (effect)

Hunger causes the hunger bar to empty.

Effect
Increases food exhaustion by 0.005 × level per game tick (removes per 80/level seconds if target has no saturation). Turns the hunger bar yellow-green. Negative levels will decrease food exhaustion. This does not increase saturation or the hunger bar.

The status effect does not decrease hunger level on Peaceful mode, although it does re-color the hunger bar.

Hunger inflicted by eating rotten flesh, raw chicken or by accepting husk attacks adds 15.0 to the player's exhaustion level over the course of 30 seconds, draining × 1⅞. When a pufferfish is eaten, 22.5 exhaustion points are added over the course of 15 seconds, draining × $2 13/16$.

The food poisoning should not be confused with effects of eating a spider eye or a poisonous potato. They deal the Poison status effect, which decreases the health value, not the hunger value.

Immune mobs
No mobs are immune. However, mobs without hunger suffer no actual effects.

Trivia

 * In Legacy Console Edition, both raw chicken and raw beef are described as "can make you ill. Cook in a furnace." However, of these two, only raw chicken actually causes "illness".
