Scientific studies revealed previously unknown properties of vitamin D and presumably this nutrient, the body gets from foods such as milk, eggs or fish, especially sea, but above all a natural process of synthesis that takes out the skin to receive sunlight-will henceforth occupy an increasingly important role in health care.
The best known and tested the roles of this essential micronutrient is to set up the calcium in the bones, so that supplementation with calcium and vitamin D in older adults is common for decades.
"As is safe and known to be effective against osteoporosis, the American Geriatrics Association recommends supplementation with calcium and vitamin D for over 65 years," recalled Moses Schapira, specialist in Gerontology and Geriatrics and Medical Director of Hirsch -Center of Excellence for Aging and Rehabilitation.
Something newest line of research linking vitamin D to cardiovascular health, but the newest is a series of studies that have been published since the end of last year in various medical journals and in different parts of the world, which prove the benefits of vitamin D to prevent loss of muscle mass, help preserve the memory, protect the nervous system of the accumulation of amyloid proteins that cause Alzheimer's disease, among others, and even-possibly-protect the elderly against chronic depression.
The possibility of living longer and growing awareness of the causes of the factors that make chronic diseases make the question of how to get to enjoy good physical and mental health, old age copper-increasing importance .
And after the new discoveries, vitamin D seems to charge a significant role in the answer to that question. It is a substance the body naturally acquired, and in any case the cost of pharmaceutical forms is so low that it suggests a "sales strategy".
Schapira warned though, especially in reference to the preventive role of Alzheimer's alleged that "even these are preliminary studies, which in any case in addition to other potential developments that are being tested in the fight against the disease, such as using insulin intranasally. "
"For now, these findings do not have a big impact care, because doctors are just the knowing" he said.
The most effective way in which the body naturally acquired vitamin D is to sunbathe moderately to avoid, of course, damage to health can cause uncontrolled exposure to ultraviolet radiation from sunlight.
The specialist said that "in reality it would seem that taking sun for an hour a day, and then only in the hands, without exposing the whole body, would be enough, the big question is posed by the fact that with age may decrease the ability and aged skin may be less effective as the body's synthesis than it is in younger people. "
"Our institution has a beautiful park of four hectares and it is common for our residents take sun, however we have noticed that this is not enough, because regardless of sun exposure, plasma levels appear to be insufficient," said Schapira.
In summary, the specialist health center located in the locality of San Miguel said that, as usual, "the physician should pesquisar a possible deficiency of vitamin D in their patients, and if it has, try to meet that lack or eventually replace empirically by hydroxy vitamin D3, is sufficient with a weekly dose. " In this sense, "intervention appears to be a very simple, cheap and simple that could improve several aspects at once."
In sum, there is no magic: vitamin D certainly seems to be more useful than it was expected to stay healthy in old age and prevent the consequences of premature aging and improve overall health from chronic diseases.
However, it is clear that healthy aging is a consequence of general health care throughout life, and hardly any dietary supplement-not replace other substance-stimulation of cognitive abilities through social life , reading, playing and learning, maintaining autonomy whenever possible, doing exercise and physical activity and emotional stability
