NUTR 245 is one course of a pair of courses designed to provide students with an in-depth understanding of nutrition and its scientific underpinnings. NUTR 245 focuses on micronutrients, including fat- and water-soluble vitamins and minerals. The second course of the sequence, NUTR 246, focuses on macronutrients and energy. The course will cover micronutrient sources; digestion and absorption; bioavailability; homeostasis; functions throughout the lifecycle including roles in promotion of health and prevention of disease; and deficiency and toxicity states. Additional concepts will include micronutrient fortification, dietary supplements as sources of micronutrients, gene-diet interactions, and the social determinants of micronutrient nutriture and their implications. The course has been designed to review and build upon students’ existing knowledge of chemistry and biology, and will provide instruction in biochemical and physiologic principles necessary to understand the aspects of micronutrients described above.
