Nutrition involves the relationship of food and nutrients to health. Biochemistry is
the science of the chemistry of living organisms. As implied by the title, this book
emphasizes the overlap between problems of nutrition and the techniques of
biochemistry.
The nutritional sciences also include many aspects of related disciplines such as
physiolog~ food chemistr3~ toxicolog~ pediatrics, and public health. Thus, any
given problem in the nutritional sciences may also be a problem in one of these
disciplines. Nevertheless, nutrition is a unique discipline because of its specific
goal, that is, improving human health by understanding the role of diet and
supplying that knowledge in everyday living.
