Local food (also regional food or food patriotism) or the local food movement is a "collaborative effort to build more locally based, self-reliant food economies - one in which sustainable food production, processing, distribution, and consumption is integrated to enhance the economic, environmental and social health of a particular place" and is considered to be a part of the broader sustainability movement.
Local food systems are an alternative to the global corporate models where producers and consumers are separated through a chain of processors/manufacturers, shippers and retailers.
As large corporations and supermarket distribution increasingly dominate the organic food market, the concept of local food, and sometimes 'sustainable food', is increasingly being used by independent farmers and food activists. Because local food tends to be fresh (or minimally processed) the bias against processed food is often at least implicit in the local food argument. Also implicit in the argument for local foods is the idea that this would also create variation. Each area would have its own foods and would have those things which are good for the local environment. This would be environmentally sustainable.
