NDSU HNES 250 Exam 1 Questions and
Answers
Example of Macro and Micro nutrients? - Answer-Macro: Carbohydrates, Lipids, and Proteins
Micro: Vitamins/Minerals
What elements make up Carbs, Lipids, and Proteins? - Answer-Essential Nutrients
Calculate Kilocalories for a meal? - Answer-Carbs: 4Kcal/g
Lipids: 9Kcal/g
Protein: 4Kcal/g
Alcohol: 7Kcal/g
Acceptable Macronutrient Distribution Range (AMDR) - Answer-A range of intakes associated with
reduced risk of chronic disease and adequate intakes of essential nutrients.
Recommended Dietary Allowance (RDA) - Answer-Nutrient intake amount sufficient to meet the needs
of 97% to 98% of the individuals in a specific life stage.
Adequate Intake (AI) - Answer-estimates nutrient intake by a group of healthy people when there is not
enough info to set an RDA.
, Tolerable Upper Intake Level (UL) - Answer-The highest daily nutrient intake level that likely poses no
health risk.
Estimated Average Requirement (EAR) - Answer-Nutrient intake value estimated to meet the
requirements of half the healthy individuals in a group.
Epidemiological study - Answer-Scientists observe how much and what kinds of foods a group of people
eat and how healthy those people are
Case-control study - Answer-Researchers compare people who do and do not have a condition/disease,
closely matching them for age/gender/key variables so that differences in other factors will stand out
Animal Study - Answer-Researchers feed animals special diets that provide or omit specific nutrients
and then observe any changes in health.
Human Intervention (Clinical Trials) - Answer-researchers ask people to adopt a new behavior to
determine the effectiveness of such interventions on the development/prevention of disease
Double Blind Experiment - Answer-Best; both subjects and researchers do not know who belongs to
which study group.
Identify reliable sources of nutrition information - Answer-1) Look at credentials (average Joe?)
2) Look at the date (Is it recent?)
3) Look at the web address (.edu .gov .org)
4) What was the message? (Bias?)
Energy Density - Answer-amount of calories per gram of food
