What is the primary protein found in breast milk?

• A. Casein
• B. Whey
• C. Gluten
• D. Albumin

Answer: (B)

The primary protein found in breast milk is whey protein, which constitutes approximately 60-80% of the total protein content. Whey proteins are easily digestible and are rich in essential amino acids. They include immunoglobulins and lactoferrin, which play roles in immune function and absorption of iron, respectively. Breast milk has a unique composition tailored for the needs of the infant, providing not only essential nutrients but also bioactive components that support growth and development. The whey proteins present in breast milk are crucial for the infant's growth, aiding in muscle development and overall nourishment. In contrast, casein is the main protein found in cow’s milk and does not constitute the major protein in human breast milk. Gluten is a protein found in wheat and is not a component of breast milk. Albumin is a plasma protein found in blood and is also not a primary component of breast milk. Understanding these distinctions is essential for recognizing the unique nutritional aspects of human milk compared to other sources.
