Nutrition and Health Midterm Exam 1
Questions Fully Solved.
Define diet - Answer The foods and beverages a person eats and drinks
Factors that influence an individual's food choices:
list factors that influence an individual's food choices. - Answer Taste and food preferences,
nutrition and weight control, physiological influences (changes in digestion and medication)
Define Nutrients - Answer Substances that support growth, maintenance, and repair of body's
tissues; components of food that are indispensable to the body's functioning; they provide
energy, serve as building material, help maintain or repair body parts, and support growth
List the 6 Nutrition classes differentiating energy and non-energy yielding nutrients. - Answer
carbohydrates,Lipids(fat), protein
vitamins, minerals (inorganic), water
Calculate total kilocalories of a food when provided with its energy-yielding nutrient content.
fat 18g
pro 30g
carb 57g - Answer carbohydrate: 4 kcal/g
lipids: 9 kcal/g
protein 4 kcal/g
ex: fat 18g, protein 30g, carbs 57g... 18x9 + 30x4 + 57x4 = 510 kcal
Estimated Average Requirement (EAR) - Answer Amount of a given nutrient that is required to
fulfill a certain task for 50% of the population; used in nutrient research and policy making and
is the basis upon which RDA values are set
Recommended Dietary Allowances (RDA) - Answer Adequacy; nutrient intake goals for
individuals; the average daily nutrient intake level that meets the needs of nearly all (97%-98%)
, or experimentally derived) in a particular life stage and gender group and assumed to be
adequate; set whenever scientific data are insufficient to allow establishment of an RDA value
Tolerable Upper Intake Levels (UL) - Answer Toxicity of vitamins and minerals, safety; the
highest average daily nutrient intake level that is likely to pose no risk of toxicity to almost all
healthy individuals of a particular life stage and gender group; usual intake above this level may
place an individual at risk of illness from nutrient toxicity
AMDR: Acceptable Macronutrient distribution range - Answer Percentages of total daily
calorie intake
(Set for the energy-yielding nutrients that are enough to provide adequate total
energy/nutrients while minimizing the risk of chronic diseases)
Acceptable Macronutrient Distribution Range for CARBS: - Answer 45-60% of energy intake
Acceptable Macronutrient Distribution Range for FAT - Answer 20-35%
Acceptable Macronutrient Distribution Range for Protein - Answer 10-35%
National Health and Nutrition Examination Survey (NHANES) - Answer government sponsored
survey that measures nutrient intake and measure the health status of population (lab
tests...cholesterol, blood, glucose...physical....height, weight , blood pressure, waist)
Adequacy - Answer enough of each type of food
Balance - Answer good mix of the myplate requirements
Energy Control - Answer not too many or too few calories
Moderation - Answer not too much fat, salt, or sugar; too much is bad for you
Variety - Answer as many different foods as possible; getting nutrients from different foods
and not juste eating the same foods everyday
