Question

Fishy odour occurs due to deficiency of this vitamin from diet -

• A. Biotin
• B. Thiamine
• C. Riboflavin
• D. Vit. A

Answer 1

The Correct Option is C

Fishy odour in the diet is primarily linked to a deficiency of Riboflavin, also known as vitamin B2. Let's explore why this is the case:

• Riboflavin Function: Riboflavin is crucial for energy production and plays a key role in metabolizing fats, drugs, and steroids. It also plays a critical role in the body's antioxidant defense mechanism.
• Deficiency Symptoms: While riboflavin deficiency can lead to several symptoms like sore throat, redness and swelling of lining of the mouth and throat, inflamed and cracking skin at the corners of the mouth, a fishy odor is notably associated due to effects on amino acid metabolism.
• Odor Explanation: The fishy smell stems from inefficient processing of certain amino acids in the body due to insufficient riboflavin, which affects the metabolic pathways.

Therefore, among the options provided, the correct answer to the fishy odor deficiency problem is Riboflavin.
