BIO SCI 9A Study Guide - Midterm Guide: Cancer, Dietary Reference Intake, Cardiovascular Disease
Document Summary
Six categories of nutrients (***fiber is not a nutrient but it does promotes health) Most prevalent diet issue in the us: overnutrition. Comprehensive analysis required: cannot just focus on one single nutrient. Influencing factors: intrinsic, extrinsic, host (microbiota interactions) In the past, we used rda, which no longer works because it is too generic = don"t. Now, we use dri = dietary reference intake = add everything together = establish. Upper limit and incorporate the role of nutrients in lifelong health. Ear = estimated average requirement = median. Rda = recommended dietary allowance = highest end of distribution. Daily value (used on labels) = newly added. Energy-producing nutrients based on the number of calories consumed per day. Energy requirements = the total energy expended by an individual supports 3 essential. Basal metabolic needs (i. e. respiration, ion transport, blood flow) Resting metabolic rate (rmr)/bmr = involves the amount of energy expended by an individual in a resting, postabsorptive state.
