The basics of the food industry
The food industry is an incredibly diverse sector of the world economy, ranging from farming to food processing, wholesaling, retailing, and food service. Some parts of it are very local, but international trade is a large component. Some parts of the food industry are very well documented, such as food processing and the major commodity markets in developed countries; other parts lack comprehensive data, such as sales of farm production and small-scale food processing in less developed countries. Certainly, the world food industry represents at least $4 trillion in value.
