40d:Food

Food is anything dwarves eat to ward off starvation, but if they are not able to attain sustenance then they will eventually die. The most common foods are meat, fish, crops, and gathered shrubs.

Eating good food will make your dwarves happy, so a good cook is an excellent investment. Also, each dwarf has a preference for certain foods.

For details on the different ways to obtain food, see the Food guide.

Types of Food

Food comes in two main varieties: meat and plants, with cooked food possibly mixing the two.

Plants can be grown underground or on the surface, and a single dedicated grower/harvester can produce enough food for all but the largest of fortresses. The advantages of plants are the infinite and readily available supply, and the versatility; plants can be brewed, made into clothing and dye, and also used as further ingredients for cooking. Further processing plants leads to greater amount delivered as an end product. The disadvantage is it's exponential growth; without control, seed/plant stockpiles will envelop all available space.

Meat can be obtained from hunting and fishing, as well as raising livestock. Uncooked meat and fish is subject to wear and will eventually rot if it is not cooked, even in barrels. The advantages are the additional skills raised during hunting, and there is less mass labor required for butchering meat or cleaning fish than planting a seed, waiting for it to grow, eating it, moving the seed back, etc. Cleaned Turtles leave behind bones and shells. Animals, when butchered, leave behind large stacks of bones, and usually raw hides and skulls. An export industry devoted to bone crafts can be profitable, and marksdwarves always benefit from a cheap supply of bolts made from bone. The disadvantages are a limited supply of food; in the current version, animals are eventually depleted from a map, and even though aquatic life restocks, there are limited numbers present at a particular time, so larger fortresses usually cannot be supported with hunting/fishing alone. There is also no way to make alcohol from animals, so without trading some plants are necessary. Finally, even though livestock breeding can be unlimited, the additional units on the map required for this to work put additional strain on the CPU, slowing the game down.

On occasion, if you have a trapper that has captured a vermin creature in an animal trap, a dwarf may eat that creature instead of other food.

Eating

A dwarf with the "Eat" task will pick up a unit of food, often according to his or her dietary preferences, then bring it to an available table or chair for consumption. A private room will normally be chosen over a public room; for this reason, note that a dwarf who owns a table-less office but no dining room will complain about the lack of tables, even if a high-quality public dining room is available. This problem is easily solved by adding a table next to such an office-chair (like you would in a dining room). Also note that eating in a high-quality dining room does wonders for a dwarf's mood.

Dwarves will eat two meals per season on average, and drink four drinks. A fortress of 100 dwarves will thus consume 800 meals (food-units) and 1600 drinks (booze-units) in a single year. Plan your stockpiles accordingly.

Storage

Food is stored in food stockpiles and may be placed in barrels. Seeds (and powders, such as flour or dye) are put in bags, which are themselves stored within barrels. Meat and prepared meals will rot (making it inedible) if not placed on a stockpile within a month or so. Plants not on a stockpile will wither, which also makes them inedible but does not produce miasma. Food on a stockpile will never rot, nor will food in a barrel even if it is not on a stockpile. Seeds will never rot no matter where they are.

According to Toady, vermin can eat your food, even when it is on a stockpile (although the amount they eat appears to be quite minimal). Food in barrels is even less likely to be eaten by vermin.

Cooked food

Raw food can be cooked into meals at a kitchen. The wider the variety of ingredients that a meal contains, the greater the number of dwarves who will have a preference for that meal. Additionally, some foods must be cooked before they can be eaten. Cooking destroys all seeds, shells and bones.

Obtaining food

The possible sources of food are farming, foraging, fishing, trading, butchering animals, hunting, and a few exotic processes. Farming is by far the most reliable, foraging is perhaps the easiest to manage, and fishing is good early in a fortresses' life. If you are constantly experiencing problems with starvation, you are well advised to look into alternate means of procuring food.

Processing food

Some food is inedible raw, and needs processing first. For example:

Fat must be rendered (kitchen) into tallow and then cooked (kitchen)
Raw fish must be cleaned (fishery)
Sweet pods must be either milled into dwarven sugar (mill/quern), processed to barrels of dwarven syrup (farmer's workshop), or brewed into barrels of dwarven rum (brewery) before they can finally be cooked (kitchen)

Unprocessed food and non-food crops will be stored in a food stockpile and take up barrel space, the bookkeeper can tell you how much of each type of "food" you have in the stocks screen.

Food is essential

Food is crucial to the survival of your fortress. Before you know it your 200 population will dive-bomb right down to 10 or even lower. Your population will go on a downward spiral because of all the Miasma and dead bodies, and of course you'll have fewer farmers/hunters to generate new food. If you're very lucky you can start again in another area, or you can get some helpful migrants.

Remember to keep a large stockpile of food. If you do not have food;

Dwarves will become unhappy and generate bad thoughts
Dwarves will start hunting for vermin instead of doing important jobs
Dwarves will get upset and start breaking things
Dwarves will get mad and start trying to kill each other
Dwarves will die from starvation
The new dead bodies will only make everyone even more depressed
