Nutrition Science

Nutrition science is the study of physiological and metabolic responses of the body to an individual’s diet. It is mainly concerned with metabolism and metabolic pathways, and uses the disciplines of biochemistry and molecular biology as part of the research process. The study of nutrition science must take into account many variables, which makes experiments time-consuming and expensive. The state of the body before and after experiments must be studied, food and waste must be analyzed, and the effect of nutrients may only be apparent over an extended period of time. 1

Another aspect of nutrition science uses the fields of psychology and anthropology to explore the influence of attitudes, beliefs, preferences, and cultural traditions on food choices. Human nutrition additionally uses economics and political science to recognize and respond to global malnutrition, and to ultimately promote optimal health that will reduce the risk of chronic diseases, and prevent common nutritional deficiency diseases. 2

Providing educating and training for individuals and communities is also a main objective for nutrition science. Basic human nutrition; nutrition and how it relates to performance for athletes; understanding and influencing food regulations; vitamins, minerals and supplements; and the relation of nutrition to diseases, are all examples where nutrition science aims to educate the public.
