Do calories really count? Do the physical laws of the conservation of energy and conservation of matter hold sway in the human body? Is there a better way to teach people about nutrition than by comparing the body to a machine and food to fuel and spare parts?
This book, which is a slighly expanded version of the author's 1994 doctoral dissertation at Columbia University explores these questions in a wholistic manner. The human being and human nutrition are looked at on the levels of body, soul and spirit.
