Nutrition plays a key role in maintaining optimal immune function. All aspects of diet and immune function will be covered as will the effect of stress on immunity and diet. In this latest edition, the concepts of genetics, epigenetics and nutrigenomics in immunity are expanded. Although a new area of research, it holds the promise of teaching us how to individualize nutrient requirements to maintain immunity and health. New research on how vitamins and minerals, antioxidants, phytochemicals and fats impact the immune system is featured. Topics include: obesity and immunity, the role of immune system in heart disease risk; aging and immunity, oxidative stress, cytokines, autoimmune diseases, and more.
Upon successful completion of this course, the student will be able to:
- List the organs, cells and enzymes of the immune system and explain the function of each component
- Explain how the components of the immune system respond to an invading antigen
- Describe phagocytosis and the inflammation reaction
- Explain how a deficiency, excess or imbalance of nutrients may affect immunity
- Explain how calorie excess and protein deprivation affects immunity
- Discuss the concepts of epigenetics and nutrigenomics and how they relate to immunity and diet
- Explain how different fatty acids — saturated, monounsaturated, omega-3 polyunsaturated and omega-6 polyunsaturated — affect the functioning of the immune system
- Make dietary recommendations on total fat intake and intake of various kinds of fatty acids.
- List five phytochemicals and discuss how they protect against disease. Make a case for increasing dietary fruits and vegetables vs. using dietary supplements to protect against oxidative stress.
- Discuss the role of vitamins in immune function: A, B-6, B-12, C, D, E, beta-carotene and folic acid
- Discuss the role of minerals in immune function: zinc, copper, iron, magnesium and selenium
- Discuss the physiological and metabolic alterations during stress and the effect on the immune system
- Explain the concept of psychoneuroimmunology and give evidence of its existence
- State three common eating problems for patients experiencing stress
- State four changes that can be made in meal planning, meal preparation or eating out that will improve the quality of the diet
- Using heart disease as a model, diagram the health consequences of prolonged stress and indicate how the immune system is involved in the development of atherosclerosis
- Show how inflammation is involved in chronic disease: obesity, cardiovascular disease and type 2 diabetes
