It's the stuff we love to hate: processed food. It has changed what we eat so much that today our ancestors would hardly recognize it as food. The modern quest for this fast and convenient food may have begun with Herman Lay and his innovative individual packages of potato chips. During World War II industrialization gave us Spam, processing techniques developed for soldier rations gave us frozen foods and an increasingly female workforce gave rise to the need for quick and easy meals. The interstate highway system literally paved the way for fast food restaurants, and people were hooked. With companies around the world churning out new products to get a slice of someone's "stomach share," questions and concerns abound about the health and safety of these foods loaded with sugar, fat and salt. The question about embracing or fighting this fast food revolution may be even more important for our future.
