If enough calcium is not regularly consumed and the calcium continues to be taken from the bones, a person`s bone mass decreases. Decreased bone mass can result in osteoporosis, fractures, and disability. Adequate calcium intake is normally important because the body cannot produce calcium alone also. Every day, the physical body loses calcium through shedding locks, skin, and nails and through sweat, urine, and feces. Every day, this lost calcium must be replaced by what a person eats.. Calcium and Bone Mass Bones might seem want hard and lifeless structures, but they are, in fact, living tissue. Old bone is continually broken down by our anatomies, and new bone can be deposited. Anytime bone can be broken down faster than it is deposited, bone weakness and osteoporosis may appear.But scientists said that was inaccurate, since there are only trace bits of genetic material from one woman. If the task is authorized by Parliament, professionals say it could likely only be utilized in about a dozen British women every year. Genetic alteration of disease risk is an important step for society and really should not be taken gently, said Dr. Peter Braude, an emeritus professor of obstetrics and gynecology at King’s University London. But he said the proposed regulations would ensure the techniques would be limited by informed couples with personal experience of mitochondrial diseases. Very similar experiments are being carried out in the usa, where the embryos aren’t being used to produce children but only for research purposes. This week, the U.S. Drug and Food Administration held a gathering to discuss the techniques.
