Fat content is minimum in
**Core Concept**
The question is testing the knowledge of the fat content in different types of milk, specifically cow's milk and other types. The correct answer requires understanding of the nutritional composition of various types of milk.
**Why the Correct Answer is Right**
The fat content in milk varies depending on the type and breed of cow. For example, whole milk from grass-fed cows typically has a higher fat content compared to milk from grain-fed cows. However, among the options, the fat content is minimum in **skimmed milk**. Skimmed milk is obtained by removing the cream from whole milk, resulting in a fat content of less than 1%. This process is achieved by centrifuging the milk to separate the cream from the skimmed milk. The skimmed milk is then packaged and sold as a low-fat or non-fat milk product.
**Why Each Wrong Option is Incorrect**
**Option A:** Whole milk from a specific breed of cow might have a higher fat content than others, but it is not the type with the minimum fat content.
**Option B:** Lactose-free milk, also known as low-lactose milk, has a similar fat content to whole milk, but with the lactose reduced or removed.
**Option C:** Goat's milk has a higher fat content compared to skimmed milk, making it a less likely option.
**Clinical Pearl / High-Yield Fact**
When selecting milk for patients with specific dietary needs, such as those with high cholesterol or lactose intolerance, it's essential to consider the fat content and protein composition of the milk product.
**Correct Answer:** D. Skimmed milk.
