As compared to Cow’s milk, human milk has
**Core Concept**
Human milk contains a unique composition of nutrients and bioactive molecules that are tailored to meet the needs of human infants. One of the key differences between human milk and cow's milk is the presence of certain bioactive compounds that promote infant growth and development. The main focus of this question is to identify a characteristic that is specific to human milk.
**Why the Correct Answer is Right**
Human milk contains a higher concentration of oligosaccharides, which are complex carbohydrates that serve as prebiotics, promoting the growth of beneficial gut bacteria in infants. These oligosaccharides are not found in significant amounts in cow's milk. The presence of oligosaccharides in human milk helps to support the development of the infant's gut microbiome, which is essential for immune system function and overall health.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because human milk does not have a higher concentration of lactose compared to cow's milk. In fact, cow's milk contains a higher amount of lactose, which is a disaccharide composed of glucose and galactose.
**Option B:** This option is incorrect because human milk does not have a lower concentration of protein compared to cow's milk. Both human milk and cow's milk contain proteins that are essential for infant growth and development, but the types of proteins present differ between the two.
**Option C:** This option is incorrect because human milk does not have a lower concentration of fat-soluble vitamins compared to cow's milk. Both human milk and cow's milk contain fat-soluble vitamins, such as vitamins A, D, E, and K, which are essential for infant growth and development.
**Clinical Pearl / High-Yield Fact**
Human milk is often referred to as "the gold standard" of infant nutrition due to its unique composition and bioactive properties. The World Health Organization recommends exclusive breastfeeding for the first six months of life to promote optimal infant growth and development.
**Correct Answer: D. Oligosaccharides**
