Micronutrients

Course code FSHN2030Units 10Level 2000Faculty of Science and Information TechnologySchool of Environmental and Life Sciences

Micronutrients (vitamins, minerals and other minor components of the human diet) will be discussed with reference to chemistry, food sources, absorption, metabolism, physiological functions, genetics, development and consequences of deficiency, requirements for Australians, therapeutic use, toxicity and assessment of status. Mechanistic principles of nutrition and their application in preventive and curative aspects of human health throughout the life cycle will be discussed.

ObjectivesOn successful completion of this course, students will be able to:

1. relate foods with specific micronutrients
2. understand the forms in which micronutrients are present in foods
3. discuss digestion, absorption, transport and metabolism of energy nutrients by human beings
4. understand the role of micronutrients in maintaining normal body metabolism and functions as well as in the prevention and treatment of chronic diseases
5. apply their knowledge of biochemistry, physiology and other sciences in the understanding of the principles of nutrition with emphasis on micro-nutrients (vitamins, minerals and other minor components of the human diet).
