Milan, July 6 (AdnKronos Hi) – Once their laughter sounds in the streets of the peninsula, sound of the whole afternoon, until sunset, regardless of the seasons . But thanks to the life of the city and the increasingly pressing commitments of parents, today children and young people "have almost stopped playing outside". Generation video game, closed at home and with bones at risk. Because since the sun no longer kisses young people, vitamin D also abandons them. "Hypovitaminosis, vitamin D deficiency, is an extremely widespread manifestation in the world's population, even in Italy, especially in the elderly less sun-exposed, but what is worrying is that it phenomenon is not only limited "in the" gray temples ", but" it also affects young people who tend today to adopt a lifestyle that does not often expose them to the sun ". Andrea Giustina, professor of endocrinology at San Raffaele in Milan and president of Gioseg (Bone Endocrinology Group of Glucocorticoid Induced Osteoporosis), explained it during the 7th update. clinical day in endocrinology and metabolism (Cuem) that took place in Milan and also saw the lack of vitamin D among the topics discussed by the experts. "It is estimated that over 90% of seniors living in retirement homes suffer from severe vitamin D deficiency. But, especially in winter, when sun exposure is already low, there is a high probability that even young people can have a significant hypovitaminosis D: On average – experts estimate – that at least half of the population, regardless of bad and age, "during the cold season" has low circulating levels of vitamin D. Also children, the generations have now abandoned the habit of exposing themselves to the sun. The sea in the summer months is not enough to balance, and having to protect the skin "with particularly high protection sunscreens, this reduces the benefit on vitamin D production". Boys are at risk for hypovitaminosis D "also because in the diet vitamin D is not particularly well represented – continues Giustina – Often we fall into the misunderstanding of seeing vitamin D as nutritious, as the vitamin in the strict sense, but it's a hormone and there's not enough food in the food, so if we want to introduce vitamin D "for food", we have to fortify the food as do the North European populations, to the point that today we are confronted with the so-called Scandinavian paradox: the countries of this geographical area, although not having a significant exposure to the sun , have – precisely for the habit of fortifying food – circulating values of vitamin D higher than those of Mediterranean countries like Italy, Greece and Spain ". From one side "the ant" that puts aside the stocks, the other "the cicada" that wastes its wealth. This is the similarity chosen by the specialist. "We, despite the sun, have a large and frequent presence of hypovitaminosis D, unlike the Scandinavian countries." This hormone – reminds the specialist – is produced by the skin after sun exposure and must then be metabolized in the first hepatic level and then in the kidney, only after the activity of vitamin D, its activity consists mainly to facilitate the absorption of calcium present in the diet and to facilitate its deposition at the skeletal level. Strategic hormone hormone for bone strength – concludes Giustina – And if levels are low, giving vitamin D can really make a difference. "
