Vitamin D does not play a fundamental role in protecting the brain

All vitamins are fundamental to the proper balance and functioning of our body, but a central place undoubtedly occupies vitamin D.

Despite almost 60% of adults (and even 80% of people elderly) have a Vitamin D deficiency, as the alarming data from the International Foundation Against Osteoporosis and the Italian Society Against Osteoporosis say, is fundamental because this vitamin will act 360 degrees on our health.

Vitamin D is essential for bones. fractures. It was discovered in 1922, when researchers noted that rickets was caused by a lack of vitamin D.

Many specific studies have shown that vitamin D can protect the respiratory system, reduce infections (colds). and the need for antibiotics.

It has been shown that overweight women suffer from a lack of vitamin D and that babies born to women with vitamin D deficiency during pregnancy have a predisposition to obesity. In women over 65, a link between normal vitamin D levels and the weight of the form has been discovered.

Research has even shown that in addition to being a potent stimulator of the immune system, vitamin D protects the heart, reducing the risk of developing atherosclerosis and hypertension.

A study published in the American Journal of Respiratory and Critical Care Medicine also showed that vitamin D deficiencies in childhood are related to a higher rate of asthma and allergy [19659002] Among the many benefits that this vitamin brings to our body, it seems like it's not a protective action for our brain.

Specifically, it is unlikely that vitamin D protects against multiple sclerosis, Parkinson's disease, Alzheimer's or other brain-related disorders. A study from the Australian University of Adelaide, published in Nutritional Neuroscience, is available

Through a systematic review of more than 70 preclinical and clinical studies, experts have badyzed the role of vitamin D in a wide range of neurodegenerative diseases: "Previous studies had shown that patients with a neurodegenerative disease tended to have low levels of vitamin D compared to healthy people. hypothesis that increased vitamin D levels, through increased exposure to UV and sunlight or supplementation, could potentially have a positive impact.A widespread belief is that these supplements may reduce risk of developing related disorders or limiting their progression.The results of our review and our in-depth badysis of the entire literature sc However, the evidence suggests that this is not the case and that there is no convincing evidence to support vitamin D as a protective agent for the brain, "says lead author Krystal Iacopetta. On the other hand, it does not diminish the importance of sun exposure.

Professor Mark Hutchinson, another author of the research, said that solar exposure could be proven. can have a beneficial impact on the brain, in other ways than those related to vitamin D levels: "It could be that a sensitive and safe sun exposure is good for the brain and that it there are new and exciting factors at play yet to identify and measure, "he concluded.
