It revealed the secret of longevity is inherited

Why do some people live much longer than average years - an issue that does not give rest to scientists all over the world. At this time the mysterious essence of the phenomenon of longevity tried to decipher the Dutch researchers.

A group of researchers of the oldest in the Netherlands Leiden University, led by Dr. Diana Van Hemst carefully examined the data of 380 European families. In each of them was with at least two long-lived relative to the age of about 90 years. The details of this research project can be read in the Canadian Medical Association Journal.

Attracted the attention of scientists, first of all, brothers, sisters and children of centenarians. In addition, the data were examined partners - both the carriers of "longevity genes" and their children. There were examined more than a thousand (1038) descendants, and 461 people entered the control group.

The discovery, which was made by scientists on the basis of the data obtained, it was rather paradoxical, and it seems even more thickened the veil of mystery surrounding the phenomenon of longevity. The researchers concluded that inherited longevity associated with low levels vitamin D   in the body, as well as changes in a specific gene. At the same time the Dutch measured the vitamin D levels of 25, in accordance with their seasonal variations. In addition, it was taken into account influencing factors are indicators of vitamin D - solarium, age, gender, body mass index, intake of vitamins, renal and genetic features of development of this vitamin by the body, each participant of the experiment.

"We found that the offspring of centenarians, who had at least one 90-year-old sibling, had low levels of vitamin D compared with the control group, regardless of the possible adverse factors" - are contained in the article, the words of scholars. The researchers also point out that in the offspring of centenarians is much less common form of the gene CYP2R1, responsible for the body's ability to store large amounts of vitamin D.

The paradox is that the low level vitamin D   It is associated with high mortality rates, cardiovascular diseases, cancer, allergy disorders intelligence. How is its lack prolongs life - another puzzle that scientists have yet to solve.

For reference:

Vitamin D is involved in the regulation of cell proliferation organs and tissues, regulates metabolic processes in the body stimulates the synthesis of a number of hormones, it plays an important role in maintaining the activity of the cardiovascular system, liver, pancreas, gastrointestinal tract. Metabolites of vitamin D regulates calcium transport in the body, exerting an important influence on the formation and maintenance of bone tissue. Also, the vitamin D regulates the absorption of calcium and phosphorus in the blood, bone and teeth. Together with vitamin A and calcium or phosphorus protects the body from cold, influenza, diabetes, eye and skin diseases.
