An Australian study showed that vitamin D deficiency in humans can have a high risk of premature death.
And the Australian study, conducted by researchers from the University of South Australia, and published in the Annals of Internal Medicine, stated that with an increase in vitamin D deficiency, the risk of death increases, according to the website. "Yorick L".
** The relationship of vitamin D with the risk of premature death
The researchers in this study, according to Al-Jazeera Net, collected data from 307 thousand and 601 people from the records of the Biobank in the United Kingdom, who were defined as having low levels of this vitamin less than 25 nmol / liter (which is the unit by which vitamin D is measured at individual) so that the average vitamin D in this group was 45.2 nanomoles / liter.
And the follow-up period lasted for 14 years, during which the researchers found that the risk of death decreased significantly with an increase in the concentration of vitamin D, especially for those who were suffering from severe deficiency, according to Al Jazeera Net.
The first author of the study, Josh Sutherland, noted that the vitamin affects "For those with health problems, the elderly, and those who do not get enough vitamin D from healthy sun exposure and dietary sources.".
added "Our study provides strong evidence of the association between low vitamin D levels and mortality, and is the first study of its kind to also include deaths related to respiratory diseases as an outcome.".
Professor Elina Hypponen, lead researcher and director of the Australian Center for Precision Health, said more studies on this topic are needed to create effective public health strategies that will help achieve national guidelines and reduce the risk of premature death associated with low vitamin D levels.
** What are the normal levels of vitamin D?
Human vitamin D levels, according to the Office of Dietary Supplements of the National Institutes of the United States, can be categorized into a vitamin D deficiency rate of less than 30 nmol/L, and a potential vitamin D deficiency of 30-30. 50 nanomol / liter, and the normal level is between 50 – 125 nanomol / liter, and high levels when the vitamin rate is higher than 125 nanomol / liter.
