Review the solved problems below to understand question phrasing, answer choices, and step-by-step solution logic prior to starting the full interactive practice drill:

Sample Question 1
Fundamentals of Food & Human Nutrition Easy • Dietetics
What are the physiological energy yield values (Atwater factors) per gram of Carbohydrate, Protein, and Lipid, respectively?
A 4 kcal, 4 kcal, 9 kcal
B 4 kcal, 9 kcal, 4 kcal
C 9 kcal, 4 kcal, 4 kcal
D 7 kcal, 4 kcal, 9 kcal
✓ Correct Answer: A - 4 kcal, 4 kcal, 9 kcal
📖 Step-by-Step Solution & Conceptual Rationale:
Standard physiological fuel values (Atwater factors) are 4 kcal/g for carbohydrates, 4 kcal/g for proteins, and 9 kcal/g for lipids (alcohol yields 7 kcal/g).
Sample Question 2
Fundamentals of Food & Human Nutrition Easy • Dietetics
Which of the following is an essential amino acid that must be supplied through dietary intake because the human body cannot synthesize it?
A Alanine
B Glutamic acid
C Lysine
D Serine
✓ Correct Answer: C - Lysine
📖 Step-by-Step Solution & Conceptual Rationale:
The 9 essential amino acids are: Phenylalanine, Valine, Threonine, Tryptophan, Isoleucine, Methionine, Histidine, Leucine, and Lysine (mnemonic: PVT TIM HaLL).
Sample Question 3
Fundamentals of Food & Human Nutrition Easy • Dietetics
Bitot's spots (foamy plaques on the bulbar conjunctiva) and xerophthalmia are classic clinical signs of deficiency of:
A Vitamin A (Retinol)
B Vitamin C (Ascorbic acid)
C Vitamin D (Calciferol)
D Vitamin E (Tocopherol)
✓ Correct Answer: A - Vitamin A (Retinol)
📖 Step-by-Step Solution & Conceptual Rationale:
Vitamin A deficiency impairs rhodopsin synthesis causing night blindness (nyctalopia), conjunctival xerosis, Bitot's spots, corneal ulceration, and keratomalacia.
Sample Question 4
Fundamentals of Food & Human Nutrition Easy • Dietetics
The clinical manifestation of 'Pellagra', characterized by the '4 Ds' (Diarrhea, Dermatitis, Dementia, Death), is caused by severe deficiency of:
A Thiamine (Vitamin B1)
B Riboflavin (Vitamin B2)
C Niacin (Vitamin B3)
D Pyridoxine (Vitamin B6)
✓ Correct Answer: C - Niacin (Vitamin B3)
📖 Step-by-Step Solution & Conceptual Rationale:
Niacin (Vitamin B3) or its precursor tryptophan deficiency produces Pellagra, characterized by bilateral symmetrical photosensitive dermatitis (Casal's necklace), diarrhea, dementia, and death.
Sample Question 5
Fundamentals of Food & Human Nutrition Easy • Dietetics
Wernicke-Korsakoff syndrome, characterized by ataxia, ophthalmoplegia, and confabulation, is caused by acute deficiency of:
A Thiamine (Vitamin B1)
B Cobalamin (Vitamin B12)
C Folic acid (Vitamin B9)
D Biotin (Vitamin B7)
✓ Correct Answer: A - Thiamine (Vitamin B1)
📖 Step-by-Step Solution & Conceptual Rationale:
Thiamine pyrophosphate (TPP) deficiency, frequently encountered in chronic alcoholism or severe malnutrition/hyperemesis, leads to Wernicke's encephalopathy and wet/dry Beriberi.
Sample Question 6
Fundamentals of Food & Human Nutrition Easy • Dietetics
Which vitamin functions as a coenzyme in the gamma-carboxylation of glutamic acid residues in blood clotting factors II, VII, IX, and X?
A Vitamin K
B Vitamin E
C Vitamin D
D Vitamin A
✓ Correct Answer: A - Vitamin K
📖 Step-by-Step Solution & Conceptual Rationale:
Vitamin K (phylloquinone/menaquinone) is the required cofactor for gamma-glutamyl carboxylase, which converts glutamate to gamma-carboxyglutamate (Gla) on clotting factors II, VII, IX, X, and protein C/S.
Sample Question 7
Fundamentals of Food & Human Nutrition Medium • Dietetics
Subacute combined degeneration of the spinal cord (loss of vibration and position sense) alongside megaloblastic anemia is diagnostic of deficiency of:
A Folic acid
B Vitamin B12 (Cobalamin)
C Iron
D Ascorbic acid
✓ Correct Answer: B - Vitamin B12 (Cobalamin)
📖 Step-by-Step Solution & Conceptual Rationale:
While both Folate and B12 deficiency produce megaloblastic anemia, ONLY Vitamin B12 deficiency leads to progressive neurological demyelination (subacute combined degeneration) due to defective myelin methylation.
Sample Question 8
Fundamentals of Food & Human Nutrition Easy • Dietetics
Non-heme iron absorption from plant foods is significantly enhanced in the intestinal lumen by the simultaneous consumption of:
A Phytates and oxalates
B Tannins in tea
C Ascorbic acid (Vitamin C)
D Calcium supplements
✓ Correct Answer: C - Ascorbic acid (Vitamin C)
📖 Step-by-Step Solution & Conceptual Rationale:
Ascorbic acid reduces ferric iron (Fe3+) to the more soluble ferrous iron (Fe2+) and forms a chelate in the duodenum, substantially enhancing non-heme iron absorption.
Sample Question 9
Fundamentals of Food & Human Nutrition Medium • Dietetics
Severe deficiency of which trace element causes dwarfism, hypogonadism, impaired wound healing, and acrodermatitis enteropathica?
A Copper
B Zinc
C Selenium
D Chromium
✓ Correct Answer: B - Zinc
📖 Step-by-Step Solution & Conceptual Rationale:
Zinc is a cofactor for > 300 metalloenzymes (DNA/RNA polymerases, alkaline phosphatase). Deficiency impairs cell proliferation, immunity, gustatory acuity (hypogeusia), and wound healing.
Sample Question 10
Fundamentals of Food & Human Nutrition Medium • Dietetics
Dietary fiber that dissolves in water to form a gel-like matrix (e.g., pectin, beta-glucan in oats) is clinically effective in:
A Lowering serum LDL cholesterol and blunting postprandial blood glucose spikes
B Accelerating gastric emptying of solid food
C Decreasing calcium excretion
D Inhibiting stomach hydrochloric acid secretion
✓ Correct Answer: A - Lowering serum LDL cholesterol and blunting postprandial blood glucose spikes
📖 Step-by-Step Solution & Conceptual Rationale:
Soluble dietary fiber binds bile acids in the gut to promote their fecal excretion (lowering LDL cholesterol) and slows carbohydrate absorption, smoothing postprandial glucose curves.
