Foods rich in calcium include dairy products such as milk, cheese, and yogurt, which are primary sources. Additionally, leafy green vegetables like spinach and kale, along with fortified plant-based drinks, can contribute to calcium intake. Other examples include fish with bones, such as canned salmon and sardines, as well as tofu and almonds. Ensuring sufficient calcium is essential for maintaining strong bones and teeth, aiding in muscle function, and supporting overall metabolic processes. A balanced diet incorporating these foods can help prevent calcium deficiencies.
