What is the main benefit of supplementing breastfeeding infants with vitamin D?

To aid in digestion
To prevent rickets
To enhance mental development
To promote weight gain

The correct answer is: To prevent rickets

Supplementing breastfeeding infants with vitamin D primarily serves to prevent rickets, a condition that results from a deficiency of vitamin D, calcium, or phosphate and leads to the softening and weakening of bones in children. Breast milk alone does not provide sufficient amounts of vitamin D, as there is only a small quantity present, making it challenging for exclusively breastfed infants to meet their vitamin D needs through diet alone. Inadequate vitamin D can lead to serious health issues, including rickets, characterized by bone deformities and growth problems. Supplementation is recommended to ensure that infants receive an adequate intake of this crucial nutrient, which plays a vital role in bone health and overall growth. This practice is supported by health organizations that promote vitamin D supplementation for breastfed infants to help prevent such conditions. The focus on preventing rickets is significant as it addresses a preventable health issue that can have long-lasting effects on a child’s skeletal development and overall health.
