Nutrition Module 1 Exam Study Guide ACTUAL QUESTIONS AND WELL REVISED ANSWERS -
LATEST AND COMPLETE UPDATE WITH VERIFIED SOLUTIONS
Q1: What is the definition of "Nutrition" as a science?
• Answer: The study of how the body uses nutrients in food to sustain life and
health.
• Rationale: Nutrition involves ingestion, digestion, absorption, transport, and
utilization of nutrients, as well as the social and psychological factors influencing
food choices.
Q2: What are the three primary functions of nutrients in the body?
• Answer: Providing energy, promoting growth and development, and regulating
body processes.
• Rationale: Nutrients serve as fuel (energy), structural building blocks (growth),
and catalysts for biochemical reactions (regulation).
Q3: Which nutrients are classified as "Macronutrients"?
• Answer: Carbohydrates, Proteins, Lipids (Fats), and Water.
• Rationale: These are required by the body in large amounts (grams or liters) to
provide energy and maintain structure.
Q4: Which nutrients are classified as "Micronutrients"?
• Answer: Vitamins and Minerals.
• Rationale: These are required in much smaller quantities (milligrams or
micrograms) and do not provide calories but are essential for chemical
reactions.
Q5: How many kilocalories (kcal) per gram are provided by Carbohydrates?
• Answer: 4 kcal/g.
,2026 GRADED A+ EXAM
• Rationale: Carbohydrates are the body's primary and most efficient source of
fuel, especially for the brain and nervous system.
Q6: How many kilocalories (kcal) per gram are provided by Lipids (Fats)?
• Answer: 9 kcal/g.
• Rationale: Fats are the most energy-dense nutrient, serving as a concentrated
storage form of energy.
Q7: How many kilocalories (kcal) per gram are provided by Proteins?
• Answer: 4 kcal/g.
• Rationale: While protein provides energy, its primary role is structural (muscle,
bone, enzymes) rather than fuel.
Q8: How many kilocalories (kcal) per gram are provided by Alcohol?
• Answer: 7 kcal/g.
• Rationale: Alcohol provides "empty calories"; it yields energy but is not
considered an essential nutrient because it interferes with growth and repair.
Q9: What is the difference between an "Essential" and a "Non-essential" nutrient?
• Answer: Essential nutrients must be consumed in the diet; non-essential
nutrients can be made by the body.
• Rationale: If an essential nutrient is omitted from the diet, a specific deficiency or
decline in health will occur.
Q10: What is an "Organic" nutrient in a chemical sense?
• Answer: A nutrient that contains the element Carbon.
• Rationale: Carbohydrates, lipids, proteins, and vitamins are organic; minerals
and water are inorganic.
Q11: What are the two main categories of vitamins?
• Answer: Water-soluble and Fat-soluble.
, 2026 GRADED A+ EXAM
• Rationale: Fat-soluble (A, D, E, K) are stored in the liver and fat; water-soluble
(B-vitamins and C) are excreted in urine if consumed in excess.
Q12: What is the difference between "Major Minerals" and "Trace Minerals"?
• Answer: Major minerals are needed in amounts >100mg/day; Trace minerals are
needed in <100mg/day.
• Rationale: Examples of major minerals include Calcium and Sodium; trace
minerals include Iron and Zinc.
Q13: What is "Satiety"?
• Answer: The feeling of fullness or satisfaction that halts the desire to eat.
• Rationale: Satiety is regulated by the hypothalamus and is influenced by blood
glucose levels and hormone signals (like leptin).
Q14: What is the difference between "Hunger" and "Appetite"?
• Answer: Hunger is a physiological drive for food; Appetite is a psychological
desire for specific foods.
• Rationale: Hunger is internal (stomach growling); appetite is external (smelling
fresh cookies even if you aren't physically hungry).
Q15: What are the three states of nutrition?
• Answer: Desirable nutrition, Overnutrition, and Undernutrition.
• Rationale: Malnutrition refers to both over- and under-consumption that leads to
poor health outcomes.
Q16: What is a "Subclinical" deficiency?
• Answer: A state of undernutrition where there are no outward, visible symptoms.
• Rationale: Biochemical tests (blood/urine) can often detect subclinical
deficiencies before physical signs (like skin rashes) appear.
Q17: What does "ABCDE" stand for in nutritional assessment?
