  6. what is primary deficiency?
    a nutrient deficiency caused by inadequate intake of nutrients. Caused by person not consuming foods

  9. define anthropometric measurements
    relating to physical measurements of the body such as height, weight, waist and body fat. Its a tool used for an individuals nutrition assessment
  10. define physical examination
    a method utilized by nurse or doctor to visually assess the physical appearance of the body
  11. how are laboratory test used as a tool of nutrition assessment?
    by testing nutrients, metabolite of the nutrient and transport protein of the nutrients in  blood or urine. its useful for uncovering early signs of malnutrition before symptoms appear
  12. what does historical information cover in nutrition assessment of individuals?
    • health history
    • drug history
    • socioeconomic history 
    • diet history

    its conducted in four ways

    1-historical information

    2-anthropometric measurement

    3-physical examination

    4-laboratory test
  15. what is NHANES
    The National Health and Nutrition Examination Survey (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The survey is unique in that it combines interviews and physical examinations.
  16. how does NHANES gather information and what kind of information does it yield?
    it gathers information using interviews and physical exams. Collected data shows nutrition related conditions such as growth retardation,heart disease and malnutrition
  17. what does "what we eat in america" refer to?
    it refers to how american's have changed their diet in the last 40 years. We eat more at fast foods with larger portions, more energy dense foods and nutrient poor foods which has resulted in general population obesity
  18. what is "healthy people?"
    its a national public health initiative under the department of health and human services that identifies threats to health and focuses effort to eliminate them
  19. what does AMDR stand for?
    • Acceptable
    • Macronutrient
    • Distribution
    • Ranges
  20. what is  AMRD?
    the composition of three energy yielding nutrients (Carbs, Lipids and proteins ) that provide adequate energy and nutrients which also reduces the risk of chronic disease
  21. what are the three energy-yielding nutrients in AMRD and what are their percent composition?
    1-Carbs at 45-65% of Kcals

    2-Lipids at 20-35% of Kcals

    3-Proteins at 10-35% of Kcals
  22. what does DRI stand for?
    Dietary Reference Intakes
  23. define DRI
    a set of nutrient intake values for healthy people in the US and Canada.
  24. What is the DRI used for?
    values are used for planning and assessing diets
  25. what are the values that make up the DRI?
    1-EAR, Estimated Average Requirements

    2-RDA, Recommended Dietary Allowances

    3-AI, Adequate Intake

    4-UL, Tolerable Upper Intake Levels
  26. define EAR
    Estimated Average Requirement

    is the average daily amount of a nutrient that will maintain a specific biochemical or physiological function in half the healthy people in a giver age and gender group
  27. define RDA
    Recommended Daily Allowance

    Is the average daily amount of a nutrient considered adequate to meet the known nutrient needs of practically all healthy people
  28. define AI
    Adequate Intake

    Is the average daily amount of a nutrient that appears sufficient to maintain a specified criterion, a value used as guide for nutrient intake when a RDA cannot be determined
  29. define UL
    Tolerable Upper Intake Level

    Is the maximum daily amount of nutrient that appears safe for most healthy people, used when a RDA cannot be determined
  30. when is RDA utilized?
    when setting a goal for dietary intake by individuals
