What food can I find and eat?
Pick from the map: mushrooms, berries, blueberries, pumpkins. (Pumpkin restores both hunger and thirst.)
In the desert: cacti and aloe. Cacti restore thirst; aloe restores a little hunger and thirst and gives edible aloe pieces.
Gather: raw meat from slain animals; raw fish by fishing.
Cook: turn raw into cooked meat / fish / mushrooms (campfire/furnace — see "How do I cook food?"). Cooked food is more nutritious and restores health.
Water: water bottles from loot; ice shards in the winter biome also restore thirst.
Granola Bars — restore health and hunger.
Buy in the in-game Server Store for coins: e.g. Cooked Meat and Water Bottle. (Not available on Premium servers — the resource store is switched off there.)
⚠ Rotten Meat — don't eat it, it harms you.
