Milk

 Milk is a nutrient-rich liquid that is produced by mammals, including cows, goats, and sheep, to feed their young. It is a good source of several essential nutrients, including calcium, vitamin D, and protein. Cow's milk is the most widely consumed type of milk and is used in a variety of dairy products, such as cheese, butter, and yogurt. Milk can also be consumed on its own or used as an ingredient in many recipes, including baked goods, smoothies, and sauces. In recent years, there has been a rise in plant-based milks, such as soy, almond, and oat milk, which are popular alternatives for people who are lactose intolerant, vegan, or looking for dairy-free options.
