Document Summary

Undernutrition inadequate intake of nutrients or energy (nutritional deficiency) Anthropometric measurement: physical dimensions/composition, easy + inexpensive, body composition, height and weight, circumferences. Biochemical measurement: lab analysis of biological sample. Symptoms often not visually apparent; must be self-reported. Dietary assessment: diet recall, food frequency questionnaire, diet record, food composition tables + dietary analysis software. Concepts of adequacy, moderation, balance, variety, nutrient density. Adequate enough nutrients and calories based on current activity + life stage. Importance of nutrient density and energy density: nutrient density the ratio of nutrients of energy. Example: roasted pork loin: energy density the ratio of energy to weight or volume. Dietary reference intakes (dris: set of four dietary assessment standards. Estimated average requirement (ear) physiological requirements for half of healthy people. Ais used for life stage: birth to 6 months. Highest level of usual daily intake to be safe: example: iron ; for adult males.
