"This unique, readable history of the vegetarian movement in America reveals its deep roots . . . [and] will make fascinating reading for proponents of a healthy lifestyle and students of Americana alike."--ForeWord Reviews

"This well-researched and accessible work is recommended for readers of U.S. social history and for vegetarians interested in knowing that the roots of their movement go deeper than the publication of Peter Singer's Animal Liberation and the founding of People for the Ethical Treatment of Animals. Fans of culinary history books . . . will also find much to love here."--Library Journal
