Which nutrient is commonly added to dairy products to prevent population deficiency?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin A
• D. Vitamin E

Answer: (B)

Vitamin D fortification of dairy products is used because it directly addresses a common deficiency risk that affects bone health. Sunlight exposure and dietary intake of vitamin D vary widely, so adding it to milk helps ensure people get enough to absorb calcium effectively and maintain strong bones. This reduces the risk of rickets in children and osteomalacia in adults. The other vitamins listed are not the standard nutrient added to dairy for population-wide deficiency prevention, since their primary roles and fortification patterns differ.
