Such are the secrets imparted with wit and style by this tough-minded suburban radical firmly ensconced in a proud family tradition of dissent--a trait that has taken quite a beating lately, she points out in her introductory essay, though it was once viewed as an integral, even defining, American attribute. She suggests in ""Food Worship"" that widespread insecurity surrounding economic and class status is what has sent Americans fleeing into the welcoming arms of mass conformity where, instructed by Esquire and Madison Avenue, they dutifully down pounds of baby bass en croute in an effort to outclass their competitors to the next corporate rung.
