Food is one of the main tile yields in Civilization: Beyond Earth.
Sources
Food is mainly acquired by having your Cities work the Terrain around them. More food can be obtained from resources, tile improvement, buildings and trade. Clearing an Alien Nest or combining artifacts may also yield a one-time food boost.
Uses
Food is gathered for one important purpose, that of growing the 
Population of your cities. Each Population consumes 2 . Note that all percentage modifiers to are applied after consumption is taken into account; as such, they will affect growth rate but not maximum population.
Some effects cause to be carried over after city growth:
- 30% with the Nanopasture building
- 10% with the Frugality virtue
- 10% with the appropriate CEL Cradle building quest option
- 10% with the appropriate Cloning Plant building quest option
City growth
A city grows by storing enough Food required to increase the population by 1.
The specific amount of Food required to increase the population by 1 is calculated as follows:
- Food required = p² + 6p + 8
where p is the current population of the city.
