Adequate intake of calcium is important to accomplish optimal peak bone mass & reduce the rate of bone loss due to increasing age (National Institutes of Health 1994). A positive calcium balance is necessary before bone growth occurs. Calcium intake & bone formation select calcium balance in the coursework of growth. In general, within the framework of calcium stored in bones.
Calcium is necessary for normal growth & development of the body frame. In the coursework of growth & maturation of the framework, namely until the early twenties in humans, calcium gathered in the framework with an average of 150 mg per day. In the coursework of maturation, the body can become excessive or deficiency in calcium balance. Beginning at age 50 in men & the time of menopause in females, bone balance becomes negative & lost bone from around the framework. This bone loss associated with the increasing incidence of fractures, in females.
Calcium intake affects peak bone mass attainment & this substance is also well able to maintain calcium skeleton throughout life. Calcium is an essential nutrient, which involves plenty of metabolic processes & provide mechanical strength to bones & teeth. Negative calcium homeostasis caused by lack of food intake, poor absorption or excessive spending that lead to loss of calcium from bone & can further increase the incidence of fractures. In this case there's epidemiological information that indicate a positive relationship between intake & bone density kaslium.
In addition to adequate amounts of calcium in the food consumed, the absorption of calcium from foods is also an important factor that determines the calcium to build & maintain bone. Thus, the necessary identification of food parts & / or functional food composition which can positively affect the absorption of calcium which can make sure that the bioavailability of calcium from food can be expected with either.
Several studies of calcium supplementation in children & adolescents, those conducted by to years has been conducted. The results showed that increasing calcium intake may be associated with increased bone mass of about 1-5%.
Intervention studies & cross-sectional study has reported a positive effect of calcium on bone mass of children & adolescents. A meta-analysis of 33 studies concluded that there is a relationship between calcium intake & bone mass in pre-menopausal females. From these results demonstrated that increased calcium intake from foods often consumed has the advantage for the development & maintenance of bones & may reduce the risk of osteoporosis in the coursework of elderly age. However, there is other research that states that did not find any obvious relationship between calcium intake with bone density.
