I normally frown on short essays published as overpriced books, and $11 is a little steep for what could easily have been a complete New York Times Magazine story (instead of the extract they ran). But the format might really make more people take these rules seriously—and that could improve, even save, countless lives. The 64 rules are mostly common sense, expressed in a sticky way (#19: “If it came from a plant, eat it; if it was made in a plant, don’t.”) I didn’t learn anything new, but I enjoyed it, and felt motivated to continue on the path I’ve been trying to walk for a few years (for example, avoiding anything with HFCs). As with self-help books, reading something I know again, especially if it’s expressed in a pithy or novel way, can be tremendously helpful. I especially liked #39, “Eat all the junk food you want as long as you cook it yourself,” which is an idea I’d sort of stumbled on. The book is a nice size, attractively designed, and not at all intimidating; may it be a huge success!
