Questions 1–50: Nutrition Fundamentals, Digestion & Metabolism
1 What is the difference between hunger and appetite?
A Hunger is an internal drive with negative sensations; appetite is an external
drive with positive sensations
B Hunger is external; appetite is internal
C Both are identical physiological processes
D Hunger is psychological; appetite is physical
Correct Answer: A. Hunger = internal physiological drive (churning, growling,
stomach pain — negative sensations). Appetite = external psychological drive
(pleasant food sensations, desire for specific foods — positive sensations).
Rationale: B reverses the drives. C ignores the distinction. D reverses the
classifications. Understanding this difference is key to addressing eating behaviors.
, 2 Which are examples of Cognitive external forces influencing eating habits?
A Habits, comfort foods, advertising, social factors, and nutritional value
B Only religious beliefs and cultural traditions
C Only sensory input like taste and smell
D Exclusively income and food access
Correct Answer: A. Cognitive external forces include habits (learned eating
patterns), comfort foods (emotional associations), advertising (media influence),
social factors (peer pressure), and nutritional value (knowledge-based choices).
Rationale: B is cultural. C is sensory. D is environmental. Cognitive forces involve
thought processes and learned behaviors related to food.
3 Vitamins are considered:
A Micronutrients and Organic
B Macronutrients and Inorganic
C Macronutrients and Organic
D Micronutrients and Inorganic
Correct Answer: A. Vitamins are micronutrients (needed in small amounts — mg
or mcg) and organic (contain carbon-hydrogen bonds). They regulate body
processes but provide no energy.
Rationale: B and C are incorrect — vitamins are micro, not macro. D is incorrect —
vitamins are organic, not inorganic. Minerals are inorganic micronutrients.
