Calcium plays an important role in our body and it is crucial for strengthening bones and teeth, especially before we reach age of 25. People whose calcium intake is inadequate before this age, have higher risk of developing osteoporosis, because calcium is taken away from bones. Calcium plays an important role in blood clotting, and some studies have shown that it can help in weight loss.
Every day we lose calcium through hair, skin, nails, and this calcium loss has to be replaced, or our body will take calcium from the bones.
Foods high in calcium are milk and other dairy products, tofu cheese, spinach, seaweeds, nuts, beans and broccoli.
