To better understand the entire gamut of the food-behavior linkage, the author unravels the workings of the mind - brain link. The book discusses this aspect and the findings add to the existing fund of knowledge in this area. Much of today’s malaise in humans can be traced to the food consumed by individuals. This book provides a comprehensive picture of the current state of human nutrition and how this can be linked to behavior.
