DIT 121 - EXAM 1- CHAPTER 1-4 Questions and
Answers (100% Correct Answers)
1. Name the six classes of nutrients and their major functions
Ans: • Macronutrients yield energy (measure in kcalories/calories)
• Carbohydrate
• Fat
• Protein
• Water and minerals do not yield energy
• Micronutrients
• Vitamins and minerals
• Human body needs small amounts
• Body uses macronutrients
• Bonds between the nutrients' atoms break
• Energy is released
• Can then be used or stored
• Macronutrients
• Provide raw material for building tissue and regulating body activities
• Proteins regulate digestion and energy metabolism
2. What is an essential nutrient? Explain why alcohol is not considered a nutrient
Ans: Foods provide nutrients—substances that provide energy, structural materials,
and regulating agents to support the growth, maintenance, and repair of the body's
tissues. Essential nutrients must be obtained from foods.
Alcohol is not nutrient since human can live without it.
4. What two credentials identify a "nutrition expert"?
Ans: Physicians and other health-care professionals
, 2 Inquire through: | Professional | Confidential Support
a. Training in nutrition is limited
Registered Dietitian (RD)
b. Degree and clinical internship
c. National exam
d. Maintain up-to-date knowledge
Dietetic technician registered (DTR)
5. What do the terms DRI, AI, RDA and UL represent?
Ans: Dietary Reference Intakes (DRI) are a set of nutrient intake values used to plan
and evaluate diets for healthy people.
• Standards defined for:
• Energy
• Nutrients
• Other dietary components
• Physical activity
Estimated Average Requirement (EAR) defines the amount of a nutrient that supports
a specific function in the body for half of the population.
Recommended Dietary Allowance (RDA) is based on the EAR and establishes a goal
for dietary intake that will meet the needs of almost all healthy people.
Adequate Intake (AI) serves a similar purpose when an RDA cannot be determined.
Estimated Energy Requirement (EER) defines the average amount of energy intake
needed to maintain energy balance, and Acceptable
Macronutrient Distribution Ranges (AMDR) define the proportions contributed by
carbohydrate, fat, and protein to a healthy diet. Carbohydrates should consist of 45
to 65 percent of kcalories, fat 20 to 35 percent, and protein 10 to 35 percent.
Tolerable Upper Intake Level (UL) establishes the highest amount that appears safe
for regular consumption.
5. Diagram and explain the "ChooseMyPlate" food guide logo.
Ans: to build a healthy plate:
