SECTION 1: NUTRITION BASICS & DIETARY GUIDELINES (Q1-30)
Q1. Which of the following BEST defines nutrition?
A) The process of eating food
B) The science of how food nourishes the body and influences health
C) The study of dieting and weight loss
D) The process of digesting food
Correct Answer: B
Rationale: Nutrition is the science that studies how food nourishes the body,
including the processes of ingestion, digestion, absorption, metabolism, and
the effects of nutrients on health and disease prevention.

,Q2. Which of the following is NOT considered a nutrient?
A) Carbohydrates
B) Lipids
C) Enzymes
D) Minerals
Correct Answer: C
Rationale: Enzymes are proteins that catalyze biochemical reactions but are not
classified as nutrients. The six classes of nutrients are carbohydrates, lipids,
proteins, vitamins, minerals, and water.
Q3. Which nutrients provide energy (calories) in the diet?
A) Carbohydrates, lipids, and proteins
B) Vitamins, minerals, and water
C) Carbohydrates, vitamins, and minerals
D) Lipids, proteins, and vitamins
Correct Answer: A
Rationale: Carbohydrates, lipids (fats), and proteins are the energy-yielding
nutrients. Vitamins, minerals, and water do not provide energy but are essential
for other bodily functions.
Q4. How many kilocalories are provided by 1 gram of carbohydrate?
A) 2 kcal
B) 4 kcal
C) 7 kcal
D) 9 kcal
Correct Answer: B
Rationale: Carbohydrates provide 4 kilocalories per gram. Proteins also provide
4 kcal per gram, while fats provide 9 kcal per gram. Alcohol provides 7 kcal
per gram but is not considered a nutrient.
Q5. How many kilocalories are provided by 1 gram of fat?
A) 2 kcal
B) 4 kcal
C) 7 kcal
2
,D) 9 kcal
Correct Answer: D
Rationale: Fat is the most energy-dense nutrient, providing 9 kilocalories per
gram. This high energy density makes fats an efficient storage form of energy
in the body.
Q6. What is the Acceptable Macronutrient Distribution Range (AMDR) for
carbohydrates?
A) 10-35% of total calories
B) 20-35% of total calories
C) 45-65% of total calories
D) 65-75% of total calories
Correct Answer: C
Rationale: The AMDR for carbohydrates is 45-65% of total daily calories. This
range is associated with reduced risk of chronic diseases while providing
adequate energy.
Q7. What is the Acceptable Macronutrient Distribution Range (AMDR) for
protein?
A) 10-35% of total calories
B) 20-35% of total calories
C) 45-65% of total calories
D) 65-75% of total calories
Correct Answer: A
Rationale: The AMDR for protein is 10-35% of total daily calories. This wide
range accommodates individual variations in protein needs based on age,
activity level, and health status.
Q8. What is the Acceptable Macronutrient Distribution Range (AMDR) for fat?
A) 10-35% of total calories
B) 20-35% of total calories
C) 45-65% of total calories
D) 65-75% of total calories
Correct Answer: B
3
, Rationale: The AMDR for fat is 20-35% of total daily calories. This range
provides adequate essential fatty acids and fat-soluble vitamins while
minimizing risk of chronic disease.
Q9. Which nutrient is considered inorganic?
A) Carbohydrates
B) Proteins
C) Lipids
D) Minerals
Correct Answer: D
Rationale: Minerals are inorganic elements that do not contain carbon. They are
obtained from soil and water and are essential for various bodily functions.
Q10. What is an essential nutrient?
A) A nutrient that the body can synthesize in adequate amounts
B) A nutrient that must be obtained from the diet because the body cannot make
it
C) A nutrient that is only found in supplements
D) A nutrient that is not required for health
Correct Answer: B
Rationale: Essential nutrients are those that the body cannot synthesize in
sufficient quantities and therefore must be obtained from the diet. Examples
include certain amino acids, fatty acids, vitamins, and minerals.
Q11. What is a calorie?
A) A measure of the weight of food
B) A measure of the energy content of food
C) A measure of the vitamin content of food
D) A measure of the water content of food
Correct Answer: B
Rationale: A calorie is a unit of measurement for energy. In nutrition, the term
"calorie" typically refers to a kilocalorie (kcal), which is the amount of
energy required to raise the temperature of 1 kilogram of water by 1 degree
Celsius.
