Food & Water are categories of consumable items crafted from materials and creatures using the Fabricator. They are only available in Survival and Hardcore mode. Consuming Food & Water is required to maintain the player's Food & Water levels or else the player risks dying from thirst or malnutrition.

While some Food can be eaten raw, this action dehydrates the player and yields significantly less Food than when it is cooked. The player can also choose to cure fish instead of cooking them, so as to make them immune to decay. Cured fish has the same Food values as cooked fish, but dehydrates the player by -2 H2O. 

To consume Food & Water items the player can left-click on the item in the PDA.

Starvation and Dehydration

A player will starve fully in about 50 minutes (1 unit of food every 30 seconds ) and so it is important to watch out, as not being cautious can mean death.

With dehydration, on the other hand, a player will die in about 33 minutes. (1 unit of thirst every 20 seconds)

In both cases, a player will be warned that they are close to starvation and/or dehydration when only 20 units of either food or water remain. Another warning will be heard when 10 units remain.

Rot and Decay

Cooked Food may raise the player's H2O levels, but it's also prone to rotting and decomposing. Curing fish instead of cooking them solves this problem but decreases hydration. Still, this is a preferable alternative for dealing with hunger when far from base or when local fish are sparse, as cured fish are the only kind of Food with any sort of long-term storage. Nutrient blocks, snacks, and gel sack also don’t rot, however, they can be rare and/or do not give ideal food levels.

Cooked Food slowly starts to lose its Food & Water value leading to Decomposition. The level will go as low as -25 H2O and -25 Food. During decomposition the Food amount lowers slowly; but when it reaches a certain level the Food becomes Ripe; Ripe Food eventually becomes rotten when it reaches -1 Food. It is recommended to eat the Food while you can during the early stages of decomposition as you will still gain some hunger.

Stages of decomposition (Cooked Fish):

  1. Starts after: ~2-3 min.
  2. Decomposing: ~2-3 min.
  3. Ripe: ~13-18 min.
  4. Rotting: ~27-33 min.

It is possible to store live fish in storage containers that will not rot until the player is ready to cook them. However, stored cooked fish will still rot regardless.

Note that decomposition also applies to plant Foods as well, and it is not possible to cook or cure them. While this means they cannot be carried around as a portable food supply, they can still be used for planting, or in the case of Creepvine, fabrication. Gel Sacks will never decay so they can be stored indefinitely while giving positive food and water.
