Question

Biotin deficiency can arise due to consumption of diet rich in

• A. raw eggs
• B. raw fish
• C. raw meat
• D. seaweeds

Hint:

Cooking eggs denatures avidin, preventing biotin deficiency.

Answer 1

The Correct Option is A

Step 1: Understanding Biotin Deficiency.
Biotin (vitamin B7) acts as a coenzyme in metabolic reactions. Its deficiency leads to dermatitis, fatigue, and hair loss.
Step 2: Relation with Raw Eggs.
Raw egg whites contain a protein called avidin, which binds strongly to biotin and prevents its absorption in the intestine. This leads to biotin deficiency if raw eggs are consumed regularly.
Step 3: Conclusion.
Hence, biotin deficiency arises due to the consumption of raw eggs.
