Nutrition
Nutrition is a science
Stated simply, nutrition is the science that studies the relationship of humans to food. The discussion of nutrition in this text involves the following topics :
ü The chemical content of food
ü The body’s use of food
ü The relationship of food to health
ü Selection of food
ü Techniques to modify food habits
ü Diet as treatment for disease
ü The relationship between medications and food intake
As this list suggests, the science of nutrition encompasses ideas from many other sciences: biology, chemistry, economics, educational theory ,nursing, medicine, pharmacology, physiology, psychology, and sociology. This connection with other disciplines suggests the far- reaching implications of good nutrition.
