A detailed and descriptive book of how the body uses food to supply it with the nutrients it needs to live. This is a complex book and would be good for an advanced reader. It is easy to get lost and confused with the information. The book does have some good diagrams that help to explain the information in a clearer way than the actual text. The book could be useful to teachers and students hoping to gain a better understanding of the role of food in the human body. ( )
