I have know idea what this string of words means in context. Agricultural products, especially staple grains are all commodities, definitionally: "a raw material or primary agricultural product that can be bought and sold, such as copper or coffee." In the Inca store house system for example, potatoes were the central commodity, and all types of foods stuffs were made from the freeze dried potatoes. In MesoAmerica corn was used for food, drink, animal feed, and so on.
