Beginning at the grocery, where most urban people today get food, Patent discusses the sources of foods that are made into such products as ``Tater Tots,'' ``V-8,'' and ``Uncle Ben's Converted Rice.'' Brief chapters discuss fruits and vegetables, grains, meats, and dairy products. Color photos contrast the various states: one spread includes shots of an appealing ``beef cow'' in a pasture, fresh cuts of meat, and a selection of processed beef products (e.g., Knox gelatine). Not about nutrition, but a useful awareness-builder. (Nonfiction. 8-11)
