Food politics is a term used to refer to the political aspects of the production and distribution of food. A state can also regulate what kinds of food may be grown, and that the food grown needs to be checked before it can be sold, or that it needs to be handled in certain ways. The state can also fix prices for certain kinds of food, or it may exclude certain groups of people from consuming it. That way, children are usually not allowed to drink alcohol, or to smoke cigarettes.
