**HOSA NUTRITION EXAM 2026/2027 TEST
BANK | 250+ PRACTICE QUESTIONS WITH
VERIFIED ANSWERS & RATIONALES | HEALTH
SCIENCE | A+ STUDY GUIDE | UPDATED**
## SECTION 1: NUTRITION FUNDAMENTALS & TERMINOLOGY (Questions
1–25)
**1. The result of those processes whereby the body takes in and uses food for
growth, development, and maintenance of health is:**
A. Respiration
B. Diet therapy
C. Nutrition
D. Digestion
**Correct Answer: C**
**Rationale:** Nutrition is the study of how the body takes in and uses food for
growth, development, and maintenance of health. Digestion (D) is the mechanical
and chemical breakdown of food, which is only one part of nutrition .
---
**2. Nutritional status is determined primarily by:**
,2|Page
A. Heredity
B. Employment
C. Personality
D. Diet
**Correct Answer: D**
**Rationale:** Nutritional status is determined by the balance between nutrient
intake and the body's requirements. Diet (what a person eats) is the primary
determinant of nutritional status, though other factors such as absorption,
metabolism, and health status also play roles .
---
**3. To nourish the body adequately and maintain health, one must:**
A. Avoid all low-nutrient-density foods
B. Eat foods containing the six classes of nutrients
C. Include fats at every meal
D. Restrict proteins at breakfast
**Correct Answer: B**
**Rationale:** Adequate nutrition requires consuming all six classes of nutrients:
carbohydrates, proteins, fats, vitamins, minerals, and water. Each class plays
essential roles in maintaining health .

**4. The six classes of nutrients include all of the following EXCEPT:**
A. Carbohydrates
B. Fiber
C. Proteins
D. Vitamins
**Correct Answer: B**
**Rationale:** The six classes of essential nutrients are carbohydrates, proteins,
fats, vitamins, minerals, and water. Fiber is a type of carbohydrate but is not itself
considered a separate nutrient class, as it is not digested or absorbed by the body .
---
**5. Nutrients used primarily to provide energy to the body are:**
A. Vitamins, water, and minerals
B. Carbohydrates, proteins, and fats
C. Proteins, vitamins, and fats
D. Vitamins, minerals, and carbohydrates
**Correct Answer: B**
, 4|Page
**Rationale:** Carbohydrates, proteins, and fats are macronutrients that provide
energy (calories). Vitamins, minerals, and water are micronutrients that do not
provide energy but are essential for metabolic processes .
---
**6. Nutrients used mainly to build and repair body tissues are:**
A. Proteins, vitamins, and minerals
B. Carbohydrates, fats, and minerals
C. Fats, water, and minerals
D. Fats, vitamins, and minerals
**Correct Answer: A**
**Rationale:** Proteins provide amino acids for tissue building and repair.
Vitamins and minerals act as cofactors in these processes. Carbohydrates and fats
are primarily energy sources .
---
**7. Foods such as potato chips, cakes, and candy are classified as:**
A. High-nutrient-density foods
B. Essential nutrient foods
C. Low-nutrient-density foods
D. Nutritious foods
