Author Michael Pollan is a prolific Food topic writer. He has a large list of Food related books that are quite excellent, and the most recent one that has peaked my interest is Food Rules: An Eaters Manual. It's tiny, cheep ($5.00), informative, and filled with great advice about healthier food choices.
Here is what Amazon.com has to say:
"Michael Pollan is the author of five books: Second Nature, A Place of My Own, The Botany of Desire, which received the Borders Original Voices Award for the best nonfiction work of 2001 and was recognized as a best book of the year by the American Booksellers Association and Amazon, and the national bestsellers, The Omnivore's Dilemma, and In Defense of Food. A longtime contributing writer to The New York Times Magazine, Pollan is also the Knight Professor of Journalism at UC Berkeley. His writing on food and agriculture has won numerous awards, including the Reuters/World Conservation Union Global Award in Environmental Journalism, the James Beard Award, and the Genesis Award from the American Humane Association."
