Protects Heart Muscles: Calcium protects your heart muscles. Sufficient amounts of calcium can help cardiac muscles to contract and relax properly. Calcium also helps the nervous system maintain the proper pressure in your arteries. If there is a calcium drop, a hormone called calcitrol is released, which contracts the smooth muscles of the arteries, thereby increasing the blood pressure.
Prevents Colon Cancer: Adequate calcium prevents overall risk of colon cancer and suppresses the growth of polyps that can lead to cancer. Alkaline foods high in calcium reduces the risk of adenomas, as well as nonmalignant tumors in the colon.
