Calcium is the most abundant element found in the human body with the highest concentrations being in the skeletal or bone system. Major dietary sources of calcium are milk and other dairy products. Adults can easily meet calcium RDA levels by incorporating these products into their diet. In addition, calcium supplements are available in the market for those who do not have adequate dietary intake.
Calcium plays a number of significant roles within the human body.
It is important for bone formation, thus, adequate intake in required for prevention of osteoporosis. Calcium has also recently been shown to reduce the risk of developing new colorectal polyps and may also lead to a small reduction in blood pressure. Although calcium is clearly a necessary element, when taken in excess it may be harmful. However, a potential problem with calcium intake that is less known is the association it may have with cancer. According to a recent report in the journal Cancer Research, there may be a direct relationship between calcium intake and prostate cancer in men.
