This book tells the fascinating story of how our very humanity–our healthy bodies and exceptional brains–evolved from eating animal foods including their natural fats. The science supporting the lack of harm–and indeed the benefit–of dietary fat, including saturated fat, has grown by leaps and bounds in recent years. In this well-researched and wide-ranging book, Gedgaudas shows a mastery of that science–and then takes it a step further. Drawing upon her many years of personal, clinical experience with patients, she explains how to take these principles into practice, bridging the gap between science and usable information for daily nutrition. This is a unique and profound contribution to the field.
