Dairy products are foods made from the milk of animals, primarily cows, goats, and sheep. Common examples include milk, cheese, yogurt, and butter. These products are rich in essential nutrients like calcium, protein, and vitamins, making them important for a healthy diet. Many people enjoy dairy products in various forms, such as drinking milk, spreading butter on toast, or adding cheese to a sandwich. Some individuals may be lactose intolerant, meaning they have difficulty digesting lactose, the sugar found in milk. Fortunately, there are lactose-free options available, allowing everyone to enjoy the benefits of dairy.
