| MCQs on Breastfeeding For FCPS, NMC, MEC and FMGE |
Understanding the biochemical and nutritional composition of breast milk is essential for taking the FCPS Part 1 exam, especially in Pediatrics and Physiology.
This post highlights some of the most frequently asked and controversial MCQs, along with explanations to help clear the concepts.
The post also highlights controversial and frequently repeated multiple-choice questions (MCQs) related to breast milk composition.
📌 1. Breast Milk is Deficient in Which of the Following?
Question:
Mother’s milk is deficient in?
Options:
A. Vitamin C ✓
B. Vitamin A
C. Casein
D. Lactalbumin
E. Pantothenic acid
Correct Answer: A. Vitamin C
Explanation:
While breast milk contains some amount of Vitamin C, it is generally lower compared to what is required for rapid growth in infants and also compared to certain formula or cow’s milk. Supplementation may be needed in some cases, especially if the mother is deficient herself.
📌 2. Comparison with Cow’s Milk – What’s Less in Mother’s Milk?
Question:
Mother’s milk is deficient in which of the following when compared to cow’s milk?
Options:
A. Vitamin C
B. Vitamin A
C. Casein ✓
D. Lactalbumin
E. Pantothenic acid
Correct Answer: C. Casein
Explanation:
Casein is a major protein in cow’s milk, making it harder to digest. Mother’s milk contains less casein and more whey proteins like lactalbumin, making it gentler on an infant’s stomach. This is actually a benefit, not a deficiency, in terms of digestibility.
📌 3. What is Higher in Human Milk Compared to Cow’s Milk?
Question:
Mother’s milk has more of which of the following compared to cow’s milk?
Options:
A. Lactose ✓
B. Protein
C. Iron
D. Calcium
Correct Answer: A. Lactose
Explanation:
Human milk is rich in lactose, which aids in brain development and helps with calcium absorption. Cow’s milk, although higher in protein and calcium, contains less lactose.
📌 4. Which Immunoglobulin is Most Abundant in Breast Milk?
Question:
Which of the following immunoglobulins is more abundant in mother’s milk?
Options:
-
IgG
-
IgM
-
IgA ✓
-
IgE
Correct Answer: IgA
Explanation:
Secretory IgA is the dominant antibody in breast milk. It provides mucosal immunity, helping protect the baby’s gut and respiratory tract from pathogens.
📌 5. Which of the Following is Absent in Mother’s Milk?
Question:
Mother’s milk doesn’t contain:
Options:
A. Iron ✓
B. Casein
C. Lactalbumin
Correct Answer: A. Iron
Explanation:
Though mother’s milk contains iron, the quantity is low. However, its bioavailability is high (50–70%), which compensates somewhat for the low quantity. After 6 months, infants often require dietary iron supplementation.
📌 6. What is Milk Notoriously Deficient In?
Question:
Milk is notoriously deficient in:
Options:
A. Vitamin C
B. Iron
C. Pantothenic acid ✓
Correct Answer: C. Pantothenic acid
Explanation:
Pantothenic acid (Vitamin B5) is low in some milk sources, although this can vary. Iron and Vitamin C are also low, but the term “notoriously deficient” typically refers to Pantothenic acid in this context based on older literature and regional MCQ trends.
🧠 Summary Table: Key Points
| Component | Human Milk | Cow’s Milk | Notes |
|---|---|---|---|
| Lactose | Higher | Lower | Aids brain development |
| Protein | Lower | Higher | More digestible |
| Casein | Lower ✓ | Higher | Harder to digest in cow’s milk |
| Iron | Low ✓ | Moderate | High bioavailability in breast milk |
| IgA | High ✓ | Low | Provides mucosal immunity |
| Pantothenic Acid | Low ✓ | Varies | Sometimes deficient |
| Vitamin C | Lower ✓ | Higher | Supplement may be needed |
✅ Final Tip for FCPS-1 Aspirants:
Don’t just memorize answers—understand the concepts. This helps tackle tricky or reworded questions effectively. Pay special attention to comparisons between human milk vs. cow’s milk, as they are favorite exam topics.
