As many Americans are concerned about vitamin D deficiency, a new study has found a causal link between them Vitamin D deficiency And dementia, according to a paper published in The American Journal of Clinical Nutrition this April.

“Vitamin D is a precursor to the hormone, which is increasing [recognized] For a wide range of effects, including brain health, but so far it’s very difficult to see what would happen if we could prevent vitamin D deficiency, “said Elena Hipponen, a senior researcher and lead author at the Australian Center for the University of South Australia’s lead author.

“Our study is the first to examine the effect of very low levels of vitamin D on dementia and stroke risk, using robust genetic analysis in large populations.”

The genetic study, supported by the National Health and Medical Research Council of Australia, analyzed data from 294,514 participants from the UK Biobank to investigate the association between 25-hydroxyvitamin D and neuroimaging symptoms associated with dementia and stroke risk.

Hipponen told Fox News that some people have lower levels of vitamin D compared to others with similar conditions based on their genes.

The study therefore grouped participants with more or less vitamin D levels based on their genes to examine the risk of developing dementia based on their vitamin D status.

“If there’s a real impact of vitamin D on the risk of dementia, this type of genetic analysis should also provide evidence for this and this is what we have seen.”

Vitamin D is a nutrient that we get from certain foods and a hormone that our bodies make. According to the Harvard TH Chan School of Public Health, calcium and phosphorus help the body absorb what builds strong bones.

“Vitamin D production in the skin is a basic natural source of vitamin D, but most people do not have adequate levels because they live in areas where sunlight is limited during the winter or are exposed to sunlight for long periods of time, according to the Harvard website.

But it is very difficult to get enough vitamin D with the foods we eat, so according to the Harvard Public Health School, the best way to ensure adequate levels is by taking a supplement.

The paper claims that this is the first study of its kind that shows a direct link between dementia and vitamin D deficiency.

According to the National Cancer Institute, the gold standard for proving the cause is a randomized clinical trial, where participants are divided into separate groups to compare treatment outcomes.

“We used genetic engineering because it’s not morally acceptable to include people with clinical vitamin D deficiency in a randomized clinical trial where they are left without the treatment they need,” Hyponen told Fox News.

The study found that low levels of vitamin D were associated with increased brain volume and increased risk of stroke.

“Furthermore, we can see this kind of genetic advantage, where people always have a slightly higher vitamin D status than others in a similar situation, which is associated with dementia when concentrations are very low,” Hyponen told Fox News.

“The results of these analyzes are very encouraging because we’re been able to show that the effect of vitamin D on the risk of dementia is very strong and is limited to people with very low concentrations, only attempts to increase concentrations. Help if you have a vitamin D deficiency.”

According to the Centers for Disease Control and Prevention (CDC), dementia is a general term for impaired cognitive function that makes it difficult to perform daily activities.

The CDC estimates that as of 2014, 5 million adults over the age of 65 were living with dementia in the United States, but more than 55 million people worldwide are living with dementia.

Although it causes many variables that affect the result, the study states that there are several limitations, including the residual confusion variables.

The study also identified technical statistical limitations regarding how vitamin D is measured, and the findings may not be generalized to different populations because the analyzes used to test the cause were limited to participants from White British ancestry.

“If we could change this reality by making sure none of us were vitamin D deficient, it would have even more benefits and we could change the health and well-being of thousands,” Hipponen said.

“Most of us are fine, but for anyone who for some reason does not receive enough vitamin D from the sun, dietary changes may not be adequate and supplementation may be necessary.”
