Many people believe, there is only calcium, needed, and have a vital role for bones. Especially for preventing brittle bones disease or osteoporosis. Inaccurate view was understandable, considering that more than 98% of calcium is domiciled in the bone. However, it is big mistakes, role of calcium outside the bones is not important.
Although a minority (only about 2%), the calcium outside the bones are even more aggressive and a very important role in preventing osteoporosis. They support the activities of enzymes, hormones, nerves, muscles, and blood clots. Calcium in the blood even be a measure of calcium levels in balance throughout the body, which is determined by parathyroid hormone.
The calcium also affect the placement of calcium into bone tissue or commonly referred to as the mineralization process. On the other hand, they were instrumental in preventing the retrieval of calcium from bone tissue, a process known as demineralization. Osteoporosis occurs when the wave itself demineralization exceeds mineralization activity. Well, that calcium levels in normal blood, the logic of mineralization and demineralization processes take place in balance.
Conversely, when levels of calcium in the blood is reduced or dropped, hormon parathyroid kalsifediol will grow or change into calcitriol. Then terjadilan increased absorption of calcium from the intestine. When he was not lack of calcium, the body a chance to reabsorb calcium from the kidneys, so the level of calcium in the blood return to normal. Hence, it is advisable to eat enough calcium intake.
Vitamin D is one source of calcium. He can be obtained from marine fish, liver, and egg yolks. But because it is not water soluble, this vitamin can not be discarded if excessive stock in the body. In fact, the buildup vitmain D can increase the production of calcitriol. In the end, result in absorption of calcium or demineralization of the intestine and bone. Fortunately, the excess vitmain D case is rare. If anything, usually akiabt swallowing excessive supplements.
It should be noted, the need for vitamin D a day is about 400 IU (international units) and must not exceed 2,000 IU. Dairy cows to be the best natural sources of calcium, because the most easily absorbed by the intestine. One liter of pure cow's milk, for example, containing 4-40 IU of vitamin D3, one egg yolk contains 150-400 IU of vitamin D3, and powdered milk is usually fortified vitamin D2 as much as 400 IU / liter. Vitamin D supplementation is only required if a person is less exposed to sunlight.
Particular protein intake, the new 1998 and 2000, JE Kerstettter and his friends prove directly that the level of protein intake is less than 0.9 g per kilogram of body weight a day, will stimulate the increase in parathyroid hormone and kasitriol, resulting in demineralization. In contrast, consumption of protein from 1 to 1.5 g for every kilogram of body weight per day to maintain balanced metabolism and calcium levels in the blood, resulting in a balance between mineralization and demineralization of bone.
Finally, osteoporosis is more common in aging men and women. The most effective prevention efforts would occur at younger ages, 10-35 years, age is generally characterized her concerns to the slimness of her body. No wonder that the process of bone mineralization in women often do not run optimally. If premenopausal bone mineralization is impaired, the risk for osteoporosis to be much greater.
To prevent osteoporosis, the options are only two. The trouble in his youth by eating calcium correctly, and have fun later in life. Or have some fun first with no regard to the type of intake that enters the body, suffering from bone loss later.e of intake that enters the body, suffering from bone loss later.
