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.

A status effect called Hunger (also known as food poisoning) directly affects the hunger bar, causing it to drain more rapidly. Visually, it shows itself by making the hunger bar a sickly yellow-green, and by generating greenish swirls around the affected player (as with other status effects). Food poisoning can be caused by eating three specific foodstuffs and taking damage from a husk. The foodstuffs are, which can cause Hunger with a chance of 80%; , which causes Hunger with a chance of 30% (both deal Hunger I for 30 seconds); and , which always causes Hunger III for 15 seconds (as well as poison and nausea).

The status effect does not decrease hunger level on Peaceful mode, although it does re-color the hunger bar. Like with other status effects, the Hunger duration does not stack (i.e. eating multiple Hunger-inflicting foods does not increase its duration), and it can be cured by drinking milk.

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".
