The concept of a food system or food regime was developed from taking a world systems view on how grains are grown: the types of grains, the method of cultivation, their use for food or feed, and the ability of citizens to transport, export, or import the desired varieties of grains -- often determine the size and type of society that develops.
Additionally, the use of grains for bread has often been a defining feature of regional, national, ethnic cultures. The types of bread produced and by whom is often shaped by the immigrants and others who settle or move through a region.
Currently, the baking industry generates over 30 billion dollars of revenue annually with the top four producers accounting for 35% and commercial producers accounting for 91% of total industry revenue (2013 BLS). Diversifying the products, producers (both in agriculture and culinary spaces), and markets for grain-based products would undeniably have a major economic impact on regional food systems, but it would also have cultural and social effects.
