ENTORNOINTELIGENTE.COM / Vitamin D not only plays an important role in the regulation of calcium balance and prevention of diseases such as rickets, osteomalacia and osteoporosis, but it is known today that further reduces the risk of falls and also decreases the risk of developing metabolic diseases such as diabetes, stroke and cardiovascular and neurodegenerative diseases such as Parkinson’s and some cancers (colon, prostate and breast) and autoimmune conditions such as MS system.
Research has found that vitamin D is essential for a large number of physiological processes and therefore need to be in adequate in the body so that the person can achieve optimum health levels. However, at present it is known that more than half of the world’s population is at risk of vitamin D deficiency, especially in populations considered at risk as people with dark, obese skin, using sunscreens, which taking drugs and anticonvulsants type glucocorticoids and patients with renal insufficiency. Low back pain, muscle weakness and bone pain are typical symptoms that you may experience an individual with severe deficiency of vitamin D.
Through sun exposure and diet can achieve optimal levels of vitamin D. The World Health Organization (WHO) recommends sunbathing at least 30 minutes a day in cooler times, ie early in the morning or after four in the afternoon, because the body makes vitamin D when the skin is exposed to direct sunlight, however, in view of the increased incidence of precancerous and cancerous skin lesions, other institutions as the American Academy of Dermatology, the population suggest caution when exposed to sunlight. On the other hand, have a diet rich in fish (tuna, salmon and sardines), fortified cereals, beef liver, mushrooms, cheese, milk and egg yolks also prevents deficiency of this vitamin.
There are many aspects, especially environmental factors that can interfere with the aim of achieving the required amount of vitamin D, so experts recommend daily supplementation. The American Society of Endocrinology suggests a minimum intake of 1000 IU daily in healthy adults and adjust this dose in populations at risk for vitamin D deficiencies Indeed, a study published in The New England Journal of Medicine 2012 stated that maintaining adequate levels of vitamin D reduces the risk of falls by 19%, and the risk of vertebral and non-vertebral fractures by 20%, which was achieved with an intake of 800-1000 IU up to date.
