WEEK 1:

Introduction to Nutrition - Principles and Importance:

QuestionAnswer
defining nutrition provision of nourishment to cells, tissues, organs, systems and the body as a whole
core concepts of nutrition Nutrient balance, Nutrient turnover, Nutrient flux, Metabolic pools and Adaptation to altered nutrient supply
nutrient balance equation intake - output (loss) = change in body stores
nutrient turnover refers to how metabolic substrates are continually being used and replaced to allow for rapid adjustments in metabolic state
nutrient flux measure of activity in metabolic pathway and isnt necessarily related to size of metabolic pools
metabolic pool types functional pool, storage pool, and precursor pool
functional pool direct involvement in body functions
storage pool provides buffering effect eg can be made available to the functional pool when required
precursor pool provides the substrate for nutrient/ metabolite synthesis
adaption to altered nutrient supply energy requirements must be met regardless so the greater the capacity to respond to adverse nutritional states the greater the capacity to survive those states
