This seventh edition of this classic textbook brings together all aspects of nutrition, including food science (biochemistry, microbiology and technology), 'health eating' and clinical nutrition. The basic chemical nature of the important food groups is concisely described in easily accessible language, together with changes which occur when food is cooked, processed and eaten. The relationship between good nutrition and good health is emphasized and, in this seventh edition, clinical nutrition has been expanded in line with the growing importance attached to the role of nutrition in disease prevention and management.
