Calcium is an essential mineral important for bone health and various bodily functions. Common dietary sources of calcium include dairy products like milk, cheese, and yogurt. For those who are lactose intolerant or prefer non-dairy options, leafy greens such as kale and broccoli, as well as fortified foods like certain cereals and plant-based milks, can also provide significant amounts of calcium. Other sources include fish with edible bones, such as sardines and salmon, which are rich in calcium. Nuts and seeds, particularly almonds and chia seeds, contribute to calcium intake as well. Incorporating a variety of these foods can help meet daily calcium needs.
