People in the US spend more than 10% of their disposable income on food each year. About a trillion dollars of this spending goes toward purchasing food to eat at home, much of it spent at grocery stores and supermarkets. Yet, very few people understand or know about how food makes it to this last step of the food supply chain and ends up on the shelves of their local store. In “The Secret Life of Groceries: The Dark Miracle of the American Supermarket,” author Benjamin Lorr traces the history and evolution of the modern-day supermarket, exposes the grocery supply chain, and reveals the often exploited and underpaid labor that goes into making sure shelves are stocked. Lorr paints a vivid picture of how agricultural and meat processing workers, fisherman, truck drivers, and grocery store workers, among others, often endure poverty and sometimes worse as they work to feed our country.
