Dairy products are a significant source of calcium, an essential nutrient crucial for maintaining strong bones and teeth. Calcium also plays other vital roles in the body, including muscle contraction, nerve transmission, and blood clotting. In addition to calcium, dairy products provide proteins, vitamins (such as Vitamin D), and other minerals. These nutrients contribute to overall health, promoting bone density and reducing the risk of osteoporosis later in life. For those who are lactose intolerant or choose not to consume dairy, alternative sources of calcium, such as leafy greens, fortified plant-based milks, and supplements, are available.
