Questions 1–60: Nutrients, Digestion & Metabolism
1 True or False: Taste and texture are often the 2 most important reasons
specific foods are consumed in North America.
A True
B False — nutritional value is most important
C False — cost is most important
D False — convenience is most important
Correct Answer: A. Taste and texture drive food choices in North America more
than nutritional value. Food manufacturers invest heavily in palatability because
consumers prioritize sensory experience.
Rationale: Understanding the primacy of taste and texture is essential for
developing effective nutrition education and dietary interventions.
, 2 True or False: Nutrition is the science that links foods to health and
disease.
A True
B False — nutrition only studies calories
C False — nutrition only studies vitamins
D False — nutrition is unrelated to disease
Correct Answer: A. Nutrition science examines the relationship between food
consumption and health outcomes — how nutrients support optimal function and
how dietary patterns contribute to or prevent chronic disease.
Rationale: Nutrition is a comprehensive science encompassing biochemistry,
physiology, epidemiology, and behavioral science.
3 Hunger is an internal drive experienced as _____, while appetite is an
external drive associated with _____.
A Negative sensations (churning, growling, stomach pain); pleasant food
sensations
B Pleasant sensations; negative sensations
C Both are identical drives
D Neither involves physical sensations
Correct Answer: A. Hunger = internal physiological drive with negative
sensations. Appetite = external psychological drive with positive sensations related
to food. Appetite can lead us to eat even when not hungry.
Rationale: Understanding this distinction is key to addressing eating behaviors
and weight management.
