📌 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
