In comparison to Cow milk, human milk has low contents of all except –
**Core Concept**
Human milk is a unique composition tailored to meet the nutritional needs of human infants. Compared to cow milk, human milk has distinct differences in its nutritional content to ensure optimal development and growth of the infant.
**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. This is in contrast to cow milk, which has a higher content of lactose, a simpler sugar. Additionally, human milk has a lower content of casein, a protein found in cow milk, but a higher content of whey proteins, which are more easily digested by infants.
**Why Each Wrong Option is Incorrect**
**Option A:** Lactose - Human milk actually has a lower content of lactose compared to cow milk, making it less suitable for human infants.
**Option B:** Oligosaccharides - Human milk indeed contains a higher content of oligosaccharides, but the question asks for a component that is not low in human milk.
**Option C:** Whey proteins - Human milk has a higher content of whey proteins, but the question asks for a component that is low in human milk.
**Option D:** Casein - Human milk has a lower content of casein, but the question asks for a component that is not low in human milk.
**Clinical Pearl / High-Yield Fact**
Human milk is a dynamic fluid that adapts to the nutritional needs of the infant, and its composition changes over time to ensure optimal growth and development.
**Correct Answer: D. Casein. Human milk has a low content of casein compared to cow milk.**
