BYU NDFS 100 EXAM 1 QUESTIONS & ANSWERS
How does nutrition affect health? - Answer -Nutrition supports growth, maintenance,
and repair of the body. Deficiencies, excesses, and imbalances of energy and nutrients
causes malnutrition disease(s). Diet influences long-term health within range of genetic
inheritance. Nutritious food is superior to supplements.
What are the 6 major nutrients, and their roles in the body? - Answer -1.
Carbohydrates- energy
2. Lipids (Fats)- energy
3. Protein- energy and structure
4. Vitamins- regulator
5. Minerals- some structural, regulators
6. Water- cell and body function
What are the calorie values for the three macronutrients and alcohol? - Answer -
Carbohydrates- 4 cal/g
Protein- 4 cal/g
Lipids (Fats)- 9 cal/g
Alcohol(s)- 7 cal/g
[in terms of energy]
Define the 5 characteristics of a healthy diet. - Answer -1. Adequacy- all essential
nutrients, fiber, and energy are in sufficient amounts
2. Balance- different numbers and proportions of food groups are consumed
3. Calorie Control- energy intake (vital!!)
4. Moderation- a diet with set constituents, no excess consumption
5. Variety- wide selection, not monotonous
What are the stages of behavior change? - Answer -Pre-contemplation (sees no
problem, no intent to change), Contemplation (admits need for change, pros/cons),
Preparation (take first steps and set goals), Action (commit to the plan and make the
changes), Maintenance (integrate new behaviors into daily life for permanent change),
and Adoption/Moving On (old behavior gone, new one is a habit/routine).
1 cup = ______ ounces liquid
1 cup= ______ ounces dry food - Answer -8 ounces
Depends on food density
4 cups = ______ - Answer -1 quart
3 teaspoons = ______
, 4 tablespoons = _______ - Answer -1 tablespoon
1/4 cup
1 ounce = _______
16 ounces = _______ - Answer -roughly 28 grams
1 pound
2.2 pounds = _______
454 grams = _______ - Answer -1 kilogram (kg)
1 pound
1 gram = _________ mg = _______ micrograms - Answer -1,000 milograms (mg)=
1,000,000 micrograms (ug/mcg)
Define DRI and RDA, and their uses. - Answer -DRI: Dietary Reference Intakes
(healthy intake values for US and Canada)
RDA: Recommended Dietary Allowances (adequacy, nutrient intake goals for people in
particular life stages and genders)
Define AI and UL, and their uses. - Answer -AI: Adequate Intakes (adequacy, nutrient
intake goals for scientific data when insufficient data is established for RDA)
UL: Tolerable Upper Intake Levels (safety, highest average daily nutrient intake to meet
1/2 requirements without toxicity)
Define EAR and AMDR, and their uses. - Answer -EAR: Estimated Average
Requirements (average daily nutrient intake for nutrition research and policy making.
AMDR: Acceptable Macronutrient Distribution Ranges (values for carbs, fats, and
proteins as %'s of total caloric intake, to reduce chronic disease risk, energy-yielding
nutrients)
What is the purpose of the Dietary Guidelines for Americans (DGA)? What are benefits
of following these recommendations? - Answer -The purpose of DGA is to offer food-
based strategies for achieving nutrient intake goals.
Benefits: high energy and nutrient intake levels,healthier life, and improved health
status.
