📓 Chapter 1: An Overview of Nutrition
Question 1:
Which of the following is classified as an energy-yielding nutrient?
A. Water
B. Vitamins
C. Carbohydrates
D. Minerals
✅ Correct Answer:C. Carbohydrates
💡 Rationale: Carbohydrates are one of the three macronutrients that provide
energy, yielding approximately 4 kcal/g. Water, vitamins, and minerals do
not yield energy but are essential for metabolic processes.
Question 2:
Which characteristic defines an essential nutrient?
A. It is synthesized by the body in sufficient amounts.
B. It can be replaced by supplements alone.
C. It must be obtained from the diet.
D. It is only needed during times of illness.
✅ Correct Answer:C. It must be obtained from the diet.
💡 Rationale: Essential nutrients are those the body cannot produce in
adequate amounts and must be consumed through food for normal function
and health maintenance.
Question 3:
How many kilocalories are provided by a food item containing 10g of fat,
20g of carbohydrate, and 5g of protein?
A. 170 kcal
B. 185 kcal
C. 205 kcal
D. 245 kcal
✅ Correct Answer:C. 205 kcal
💡 Rationale: Fat provides 9 kcal/g, carbs and protein each provide 4 kcal/g.
Calculation: (10×9) + (20×4) + (5×4) = 90 + 80 + 20 = 190 kcal.

Question 4:
Which nutrient is organic but does not yield energy?
A. Protein
B. Water
C. Vitamin C
D. Mineral
✅ Correct Answer:C. Vitamin C
💡 Rationale: Vitamins are organic compounds required for metabolism but
do not provide energy. Vitamin C is water-soluble and critical for collagen
synthesis and antioxidant function.
Question 5:
The term "diet" in nutrition refers to:
A. Weight-loss plans
B. Caloric restriction
C. The foods and beverages a person consumes
D. Organic food intake only
✅ Correct Answer:C. The foods and beverages a person consumes
💡 Rationale: In nutritional science, "diet" refers broadly to all food and
drink consumed, not just those linked to weight management.
Question 6:
A person who consumes adequate calories but has micronutrient deficiencies
is likely experiencing:
A. Overnutrition
B. Secondary malnutrition
C. Hidden hunger
D. Protein-energy malnutrition
✅ Correct Answer:C. Hidden hunger
💡 Rationale: Hidden hunger refers to micronutrient deficiencies in
individuals whose caloric intake may appear sufficient but lacks vital
vitamins and minerals.
Question 7:
What does the term “nutrient density” refer to?
A. The calorie content per gram
B. The ratio of fat to protein
