Dairy products are foods made from the milk of mammals, 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 balanced diet. The production of dairy products involves processes such as pasteurization, fermentation, and aging. Cheese can vary widely in flavor and texture, while yogurt is often enjoyed for its probiotic benefits. Many people consume dairy products daily, but some may be lactose intolerant, meaning they have difficulty digesting lactose, the sugar found in milk.
