Dairy: An Introduction

Dairy products are derived from the milk of mammals, primarily cows, but also goats, sheep, and buffalo. They are an essential part of the human diet, providing valuable nutrients such as calcium, protein, and vitamin D. Common dairy products include milk, cheese, yogurt, and butter.

Benefits of Dairy Products

Dairy products are a rich source of calcium, which is crucial for the development and maintenance of healthy bones and teeth. Additionally, they provide high-quality protein, essential vitamins and minerals, and are often fortified with vitamin D, which helps the body absorb calcium. Consuming dairy products as part of a balanced diet can contribute to overall health and well-being.
