Food is the basic source of nutrition to both humans and animals. Consuming food provides saturation. Deprivation of food leads to malnutrition and, if prolonged, death.

Summary

Food is measured in units of nutrition. Most raw foods, as well as discrete food like pemmican, give 0.05 nutrition per unit. Prepared meals, such as simple meals or lavish meals, give 0.9 or 1.0 nutrition.

Baseline adult humans require 1.6 nutrition per day. They can "store" 1.0 nutrition at any one time. As they start to eat while they are "hungry" (0.25 saturation), meals are subject to slight overeating. A rough baseline of 2 meals per day, or 32 units of pemmican/raw food, is required to feed a person.

By default, colonists will eat the tastiest valid food; from Lavish to Raw. Certain traits or ideology preceptsContent added by the Ideology DLC may change their priorities. You can control what foods colonists are able to eat in the Assign tab. You can also select a colonist's or prisoner's food policy in the Health tab.

Raw food

Food found in its natural stage is raw. Most raw foods will give the −7 Ate Raw Food moodlet to an ordinary colonist. All raw food comes with an innate chance of food poisoning. Milk, berries, and insect jelly can be eaten without mood penalty, but can still give food poisoning.

You can cook food into meals at an electric stove, fueled stove or campfire, or process it at a nutrient paste dispenser. In addition to tasting better, cooked food allows you to get more nutrition off the same amount of raw food. For example, a simple meal costs 0.5 nutrition to make, but gives 0.9 nutrition when eaten - this equates to 180% more food. Food poisoning of a prepared meal is based off of Cooking skill and cleanliness of the room. Nutrient paste can never cause food poisoning.

Raw food can be obtained from a variety of sources:

Degradation

As of version 0.15.1279 (29 August 2016) there is a message telling you when food has spoiled.

Food will be destroyed if left unattended by two entirely seperate factors: exposure and temperature.

  • Storing food in temperatures above 0 °C (32 °F) will spoil over time. Temperatures below 10 °C (50 °F) will slow down spoiling by a factor of 1/temp in Celsius. See Temperature for details.
    • In the early game, food spoilage can pose a threat if located on warm biomes. A freezer room can be created by placing enough coolers in proportion to its size - the bigger the storage, the more coolers required.

For example: a raider is killed and drops a fine meal outdoors, while temperature is below freezing. The meal will not spoil, but it will still deteriorate, and lose HP. Conversely, a meal stored inside a stockpile at room temperature will spoil rather than deteriorating.

Once spoiled, food will vanish and can never be recovered. However, food can be eaten at any stage before spoiling with no negative effect. Food poisoning comes from other sources, such as a messy kitchen or unskilled cook.

Analysis

As a rough rule of thumb - 25 tiles of rice / potatoes / corn, in ordinary soil, is enough to feed a single colonist in Losing is Fun indefintely, when:

  1. They are cooked into and eaten as simple meals.
  2. A grower's Plants skill is competent; 6 Plants is enough.
  3. Crops are harvested reasonably quickly. 25 tiles gives a little extra food in case of emergency. However, it assumes that growing is Priority #1 for your grower.
  4. Your colony has a year-round growing season.

20 tiles of rice/corn in rich soil (not potatoes) are also enough to feed a colonist, in the same conditions, with some food in reserve. Difficulty will reduce plant yield; if playing in difficulties lower than Losing is Fun, then you technically need less crop to survive. If your biome doesn't have a winter, then just plant your tiles of rice, and you don't really have to worry about managing food.

Of the three "main" food crops:

  • Rice grows quickly, but gives the least per harvest. Rice is stable; a blight will not impact you as much as with other crops. However, because it needs to be harvested multiple times, it takes more work for the same amount of food. If winter is approaching, then rice can be a "last harvest" crop.
  • Corn is the opposite of rice. It grows slowly, but gives the most per harvest. It takes much less work to harvest corn than it does rice, but your corn harvest is impacted more by disasters like blight and fire. Corn cannot be grown in hydroponics.
  • Potatoes are in the middle in terms of speed and harvest size. Potatoes are notable for their low Fertility Sensitivty, meaning the quality of soil impacts them much less. They are great to grow in stony soil and gravel, but bad to grow in rich soil or hydroponics.

Rice, corn, and potatoes give roughly the same amount of food per day, assuming regular soil is used. Rice is ever so slightly higher than the other 2 crops.
