QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) |ALREADY GRADED A+
1. Which hormone is primarily secreted by the stomach in response to fasting and stimulates
the hypothalamus to increase hunger and food intake?
A. Leptin
B. Ghrelin
C. Neuropeptide Y
D. Cholecystokinin (CCK)
[CORRECT] B. Ghrelin
Rationale: Ghrelin is known as the "hunger hormone." It is secreted primarily by the empty
stomach and acts on the hypothalamus (specifically the arcuate nucleus) to stimulate
appetite. Leptin, conversely, is secreted by adipose tissue and signals satiety.
2. A patient has sustained significant damage to the ventromedial hypothalamus. Which of
the following physiological outcomes is most likely?
A. Complete cessation of food intake (aphagia)
B. Dramatic increase in hunger and weight gain
C. Inability to regulate body temperature
D. Increased secretion of CCK
[CORRECT] B. Dramatic increase in hunger and weight gain
Rationale: The ventromedial hypothalamus (VMH) is historically considered the "satiety
center." Lesions in this area lead to hyperphagia (excessive eating) and obesity because the
satiety signal is disrupted. Lesions in the lateral hypothalamus lead to aphagia (lack of eating).
,3. Leptin resistance is a hallmark of obesity. What is the primary mechanism by which leptin
functions in a healthy individual?
A. It stimulates gastric emptying.
B. It inhibits neuropeptide Y (NPY) and Agouti-related peptide (AgRP) in the hypothalamus.
C. It increases ghrelin secretion from adipose tissue.
D. It stimulates the release of insulin from the pancreas.
[CORRECT] B. It inhibits neuropeptide Y (NPY) and Agouti-related peptide (AgRP) in the
hypothalamus.
Rationale: Leptin acts on the hypothalamus to inhibit orexigenic (appetite-stimulating)
neurons like NPY and AgRP while stimulating anorexigenic (appetite-suppressing) neurons like
POMC. This results in reduced food intake and increased energy expenditure.
4. Neuropeptide Y (NPY) is a potent neurotransmitter involved in feeding behavior. What is its
primary effect?
A. It induces satiety and reduces meal size.
B. It delays gastric emptying.
C. It stimulates carbohydrate craving and increases food intake.
D. It increases thermogenesis in brown adipose tissue.
[CORRECT] C. It stimulates carbohydrate craving and increases food intake.
Rationale: NPY is one of the strongest stimulators of appetite. It is released in the
hypothalamus in response to fasting or low leptin levels and specifically drives the intake of
carbohydrates.
5. The Estimated Average Requirement (EAR) serves as the foundation for setting other DRIs.
Which of the following statements accurately describes the EAR?
A. It is the intake level that meets the needs of 97-98% of healthy individuals.
B. It is the average daily nutrient intake level estimated to meet the requirement of half the
healthy individuals in a particular life stage group.
C. It is the recommended intake for all individuals in a specific group to prevent deficiency.
,D. It is the maximum daily intake unlikely to cause adverse health effects.
[CORRECT] B. It is the average daily nutrient intake level estimated to meet the requirement
of half the healthy individuals in a particular life stage group.
Rationale: The EAR is the median intake estimated to meet the needs of 50% of a healthy
population. It is used to assess dietary adequacy of populations and to set the RDA.
6. The Acceptable Macronutrient Distribution Range (AMDR) for fat in an adult diet is 20–35%
of total calories. Which of the following describes the purpose of the AMDR?
A. To set minimum requirements to prevent acute deficiency diseases.
B. To set maximum limits to prevent toxicity.
C. To reduce the risk of chronic diseases while ensuring adequate essential nutrient intake.
D. To calculate the exact grams of protein needed for positive nitrogen balance.
[CORRECT] C. To reduce the risk of chronic diseases while ensuring adequate essential
nutrient intake.
Rationale: AMDRs are ranges of intake for energy sources (carbs, fats, proteins) associated
with reduced risk of chronic diseases (like heart disease or diabetes) while providing essential
nutrients. Intake below or above the range may increase health risks.
7. The Tolerable Upper Intake Level (UL) is a critical reference value. Which statement best
defines the UL?
A. The highest average daily nutrient intake level likely to pose no risk of adverse health
effects to almost all individuals in the general population.
B. The minimum intake required to cure a specific deficiency.
C. The maximum amount of a nutrient that can be absorbed in the small intestine.
D. The level at which nutrient-drug interactions become negligible.
[CORRECT] A. The highest average daily nutrient intake level likely to pose no risk of adverse
health effects to almost all individuals in the general population.
, Rationale: The UL represents the maximum chronic daily intake unlikely to cause adverse
health effects in the general population. As intake increases above the UL, the risk of adverse
effects increases.
8. If a nutrient lacks sufficient scientific evidence to establish an RDA, which DRI value is
established instead?
A. UL (Tolerable Upper Intake Level)
B. EAR (Estimated Average Requirement)
C. AI (Adequate Intake)
D. EER (Estimated Energy Requirement)
[CORRECT] C. AI (Adequate Intake)
Rationale: An Adequate Intake (AI) is set when there is not enough scientific evidence to
calculate an EAR (and thus an RDA). The AI is based on observed or experimentally
determined estimates of nutrient intake by healthy people.
9. A healthy male consumes a diet where 15% of his total calories come from protein. Based
on the AMDR, is this intake appropriate?
A. No, it is below the AMDR of 20–35%.
B. No, it is above the UL.
C. Yes, it falls within the AMDR of 10–35%.
D. Yes, but only if he is an endurance athlete.
[CORRECT] C. Yes, it falls within the AMDR of 10–35%.
Rationale: The AMDR for protein for adults is 10% to 35% of total calories. A 15% intake falls
comfortably within this range, supporting general health and nitrogen balance without
requiring specific athletic justification.
10. Under the Dietary Supplement Health and Education Act (DSHEA) of 1994, how are dietary
supplements regulated?
