I'm looking for book recommendations for an undergraduate seminar I'm teaching. It's a seminar that will be credited as science, and the focus is food. I've chosen three books to read and discuss, but the students will choose a fourth book to read and report on. The broad areas I can see as relevant are the science of cooking, nutrition and agriculture. I'd welcome any suggestions you might had -- the main things I'm looking for are books that have some science focus, but are readable --e.g., not textbooks, unless there are some good ones out there I don't know about. The books that are required are Eat, Drink and Be Healthy, The Science of Cooking (or What Einstein Told His Cook -- haven't decided), and The Omnivore's Dilemma.
