Which of the following is a common source of dietary calcium?

Dairy products are widely recognized as a primary source of dietary calcium because they contain high levels of this essential mineral, which is crucial for maintaining healthy bones and teeth. Foods such as milk, cheese, and yogurt not only provide calcium but also come with the added benefit of being rich in protein and other nutrients. Consuming adequate amounts of dairy is particularly important during periods of growth, such as childhood and adolescence, as well as for older adults to help prevent osteoporosis.

While whole grains, red meat, and fruits contain some calcium, they do not provide as much as dairy products. Whole grains may contribute to overall nutrition and include some minerals, but they are not considered a significant source of calcium. Red meat, while nutritious in terms of protein and iron, offers minimal calcium. Fruits can provide various vitamins and minerals but are typically low in calcium compared to dairy. Thus, dairy products stand out as the most concentrated and common dietary source of calcium.
