Bone formation of dietary calcium

In the bones of the human life cycle starts decreasing with the age of thirty, where stops building bones and accumulation.
So it is not surprising that you feel that the doctors are talking about the issue of when a fateful advised the young to take the maximum amount of calcium and another nutrient is vitamin D (D) to maintain the integrity of the bone and its resistance as long as possible.
For people who have crossed the age of thirty is considered the same elements to the same degree of importance for the young because they are slowing the process of bone erosion associated with advanced age.
However, the importance of calcium is not confined to the bone.
Says a spokeswoman for the American Society for Nutrition, an expert nutrition Katherine Toulmadj: "Calcium is also important to prevent the formation of colon cancer and to help the muscles to contract properly, including the heart muscle. Also plays calcium role in reducing blood pressure and help the body burn fat."
Calcium is also highly important for many aspects of health, which makes the body begins to withdraw from the bones if it is not is received from the diet in sufficient quantities.
The agency advises U.S. Agriculture of people between 19 and 50 years, eating up to 1,000 mg daily dose of calcium and 1,200 mg for people over fifty. At a time when many people turn to nutritional supplements, the Toulmadj say that the food is the best choice.
Toulmadj says: "My advice is personal eating three meals rich in dairy products provides a third of the need for food. May be available in a glass of milk or soy milk or fresh orange juice or a cup of yogurt or cheese."
For people who are allergic to milk protein, it is possible to drink skimmed milk.
There are also calcium-rich foods other than dairy products such as grains, especially dark Al_khasroat them but it is difficult to obtain large amounts of calcium from these foods.
However, the bone-building does not depend on calcium alone.
Toulmadj says: "The important factor here is vitamin D (D) is of the same class of calcium important if not more important. Because without this vitamin will not be able to precisely the body absorb calcium.
However, vitamin D (D) can not be obtained from any component of the diet, but human skin using ultraviolet rays which are reflected on the skin with sunlight to manufacture this vitamin.
According to Toulmadj, people do not go out into the sun now, as was the case in the past and if it happened and went out often cover their bodies protective creams from the sun. So it is natural to see a big shortage of this vitamin in children, which could result in disease rickets. The lack of this vitamin to the lack of absorption of calcium, causing fragile bones and curvature of the feet.
This problem is clearly in black children because of skin pigments inhibit the absorption of sunlight. Toulmadj says that given the seriousness of the problem, the American Academy of Sciences considers issuing a new report could raise the recommended amount of 400 units to 800 to 1,000 units a day.
The signature of a half-hour of the day outside the home in the middle of the day is sufficient to raise the levels of the vitamin in the body.
Toulmadj concludes that it is essential that everyone is obtained adequate amounts of calcium and vitamin on a daily basis from an early age and continue to do so throughout the lifespan.
