Which description of colostrum is correct?

• A. Water-based liquid with no nutrients.
• B. Colostrum; high in antibodies and nutrients, supports immune protection and gut maturation.
• C. Milk that comes later in the first week.
• D. Colostrum is produced only during pregnancy.

Answer: (B)

Colostrum is the first milk produced after birth, and it is packed with antibodies and nutrients. This early milk provides passive immune protection for the newborn, thanks to high levels of immunoglobulins (especially IgA) and other immune factors, while also delivering nutrients that support quick growth and development. It contains growth factors that help the gut lining mature and establish a healthy barrier to pathogens, which is crucial for a newborn’s developing digestive system. Although the volume is small, its composition is highly concentrated and specifically geared toward boosting immunity and preparing the gut for digestion. This timing—produced in late pregnancy and in the first days after birth—sets it apart from later, transitional or mature milk, which explains why the description emphasizing high antibodies and nutrients that support immune protection and gut maturation is the accurate one.
