As we fill our shopping carts and pantries with the latest neatly boxed and wrapped goodies of industry, we continue down a path that began some ten thousand years ago with the emergence of agriculture - an event that would eventually, along with steel roller mills in the 1880s, farm subsidies in the 1970s and an explosion of highly processed and packaged foods, lead to one of the greatest unintended consequences in human history: The shift in how and where the human body captures much-needed energy (calories) to power our demanding bodies and modern lifestyle. This "little" book is about that journey and a story about an unlikely cast of characters to whom we owe much of our current success as a species and any future success and health we may hope to achieve.
