HLTH 640 Quiz: Food Choices and
Guidelines, Digestion, and Carbohydrates
Exam
**1. Which of the following best defines the concept of "energy
density" in foods?**
- **A)** The number of calories per gram of food
- **B)** The amount of vitamins per serving size
- **C)** The glycemic index of the food
- **D)** The water content percentage
**Answer: A**
**Rationale:** Energy density is a measure of the calorie content of
food relative to its weight (grams). Foods high in water and fiber have
low energy density, while foods high in fat have high energy density.
This is crucial for weight management because consuming low-
energy-dense foods can promote satiety with fewer calories.

**2. According to the 2020-2025 Dietary Guidelines for Americans,
what is the recommended limit for added sugars in a 2,000-calorie
diet?**
- **A)** Less than 10% of total daily calories
- **B)** Less than 25 grams
- **C)** Less than 50 grams
,- **D)** Less than 5% of total daily calories
**Answer: A**
**Rationale:** The guidelines recommend that added sugars make
up less than 10% of total daily calories. For a 2,000-calorie diet, this
equates to about 200 calories or 50 grams of added sugar. The
recommendation is based on the association between high added
sugar intake and increased risk of cardiovascular disease, obesity, and
type 2 diabetes.

**3. A "nutrient-dense" food is characterized by:**
- **A)** High calorie content with low micronutrient content
- **B)** High amounts of vitamins, minerals, and phytochemicals
relative to its calorie content
- **C)** High fat and sugar content
- **D)** Being a processed food with added fortification
**Answer: B**
**Rationale:** Nutrient density refers to the amount of beneficial
nutrients (vitamins, minerals, fiber) a food provides per calorie.
Foods like leafy greens, berries, and lean proteins are nutrient-dense.
This contrasts with "energy-dense" foods which provide many
calories but few nutrients.

,**4. Which of the following is a key characteristic of the
Mediterranean Diet pattern?**
- **A)** High intake of red meat and processed meats
- **B)** Emphasis on monounsaturated fats, primarily from olive oil
- **C)** Low intake of fish and seafood
- **D)** High intake of refined grains
**Answer: B**
**Rationale:** The Mediterranean diet emphasizes plant-based
foods, whole grains, legumes, nuts, and olive oil as the primary fat
source. Olive oil is rich in monounsaturated fatty acids (MUFAs),
which are associated with improved lipid profiles and reduced
inflammation.
---
**5. The Acceptable Macronutrient Distribution Range (AMDR) for
carbohydrates is:**
- **A)** 10-35% of total calories
- **B)** 45-65% of total calories
- **C)** 20-35% of total calories
- **D)** 65-75% of total calories
**Answer: B**
**Rationale:** The AMDR for carbohydrates is 45-65% of total daily
caloric intake. This range is associated with reduced risk of chronic
diseases while providing adequate energy for bodily functions and
physical activity.

**6. Which of the following is a primary function of Dietary
Reference Intakes (DRIs)?**
- **A)** To treat specific diseases with diet
- **B)** To provide standards for adequate nutrient intake to prevent
deficiency and reduce chronic disease risk
- **C)** To regulate food labeling in the United States
- **D)** To govern organic food certification
**Answer: B**
**Rationale:** DRIs are a set of reference values used to plan and
assess nutrient intakes for healthy people. They include the
Recommended Dietary Allowance (RDA), Adequate Intake (AI),
Tolerable Upper Intake Level (UL), and Estimated Average
Requirement (EAR).
---
**7. What does the "Daily Value" (DV) percentage on a food label
represent?**
- **A)** The recommended daily intake for a specific nutrient based
on a 2,500-calorie diet
- **B)** How much a serving of food contributes to the total daily
intake of a nutrient, based on a 2,000-calorie diet
- **C)** The exact amount of a nutrient needed by every individual
regardless of age
