Which of these is considered a dietary source of Vitamin B12?

• A. Fruits
• B. Cereals
• C. Dairy products
• D. Vegetables

Answer: (C)

The correct choice of dairy products as a dietary source of Vitamin B12 is based on the important role that dairy plays in providing this essential nutrient. Vitamin B12, also known as cobalamin, is primarily found in animal-based products. Therefore, dairy items such as milk, cheese, and yogurt are significant sources of this vitamin.

Vitamin B12 is crucial for various bodily functions, including the formation of red blood cells, maintenance of the nervous system, and DNA synthesis. While fruits and vegetables do not contain Vitamin B12, and cereals may be fortified with B12 but are not natural sources, dairy products inherently provide this essential nutrient. This makes dairy a key dietary component for individuals needing to ensure adequate B12 intake, particularly in populations that may not consume meat or fish.
