Everything you know about Vitamin D has never been wrong

Vitamin D is unable to treat sclerosis, rheumatoid arthritis, or reduce the incidence of cancer.

In recent times, Vitamin D has been promoted as a medicinal drug, able to cure most types of diseases. Is this true? A new analysis of existing Vitamin D studies, conducted at the University of Alberta Canada, found that most of the vitamin D value judgments have not been verified. The article is titled: ' An overview of the 10 existing statements about the value of Vitamin D '.

The article has shown that there is absolutely no evidence to confirm that Vitamin D is capable of treating sclerosis, depression or rheumatoid arthritis. It also does not reduce the incidence of cancer and respiratory infections.

The author of the analysis paper said: ' We can read articles about vitamin D deficiency that are related or lead to all kinds of diseases. These articles are often derived from small, unreliable and practical studies. '

Very few foods contain Vitamin D, so this is a vitamin that needs to be added outside.But how much additional is enough?

Of all the rumors, there is only one valuable assessment, that is, Vitamin D reduces the risk of fractures and the number of falls. Proven studies have shown that taking Vitamin D may reduce the number of falls in the elderly. In addition, combining calcium supplements can reduce fractures. However, the level of impact of Vitamin D is not too significant.

The lead author of the analysis, Michael Allan, Director of Evidence-based Medicine at the University of Alberta Department of Medicine & Dentistry, said: 'If a group of people has a 15% chance of having a fracture in 10 years To use Vitamin D within 10 years, we can prevent 1/50 of the fractures in that group. The 1/50 ratio achieved after 10 years is recognized by many people. And it is also the only application of Vitamin D that we know until now. '

Currently, the most common test to check your body's Vitamin D level is called 25- (OH) D. But the researchers do not recommend this test due to very high errors between close tests, on the same person (about 10-20%). There are no specific standards or studies to figure out the number of vitamin D deficiency markers. So the data on the number of people believed to be Vitamin D deficient can be exaggerated.

Allan said: 'A person in his 40s has a significant ability to absorb Vitamin D. Significantly less here means there is no specific quantitative figure. '

In short, Vitamin D exists naturally in very few foods (fish oil, fish fat, egg yolk), and the human body produces Vitamin D when exposed to sunlight. According to the Centers for Disease Control and Prevention, Vitamin D deficiency leads to rickets in children and osteoporosis in the elderly.
