Vitamin D is an important vitamin, the lack of which causes dementia or Alzheimer’s, most often in the elderly. This statement of scientists who conducted a large study published in the journal “Neurology Journal”.
Lead researcher at the University of Exeter Medical School David Llewellyn in a press release says that the huge connection between vitamin D and dementia or Alzheimer’s disease surprised them.
Vitamin D and Alzheimer’s disease
This survey took into account data from several years ago when 1,658 Americans aged 65 years and over participated in the cardiovascular study at the National Heart, Blood and Lung Institute.
The researchers found that adults with moderate vitamin D deficiency have a 53% higher risk of developing dementia, and the risk of those with severe vitamin D deficiency is 125%.
Similarly, for Alzheimer’s disease, the most common form of dementia, the results show that moderate vitamin D deficiency has a risk of up to 69%, whereas in people with severe deficiency, even 122%.
Clinical trials are not specific, and they can not, of course, verify that foods, especially fish or vitamin D supplements, can slow or prevent the onset of dementia or Alzheimer’s disease.
I will not miss vegetarian and vegetarian dishes. Of course, there are other sources of vitamin D, which correspond to this method of nutrition. You can download a PDF document using Vegan / Vegetarian sources of vitamin D by clicking on this link.
However, although low levels of vitamin D are not the direct cause of dementia, be cautious in the early stages of this disorder.
More than five million Americans live with Alzheimer’s disease. According to the latest data from the Chicago Alzheimer’s Association, one in three patients dies from some form of dementia. Kate Fargo, director of scientific programs and links with the Alzheimer’s Association, stressed that the hippocampus is a region of the brain that is full of vitamin D receptors. She believes that the link begins right here.
Various studies show that little or no exposure to the sun, without using additives or foods such as salmon, sardines, egg yolks, etc., Causes Vitamin D deficiency.
A study in Denmark showed a link between the prevalence of Alzheimer’s disease and the lack of vitamin D.
Another study, conducted in Australia and France, demonstrated a close relationship between vitamin D and memory improvement.
Studies have shown that the use of vitamin D prevents asthma, diabetes and cancer.
Whatever the expectations of people and their beliefs, it is scientifically proven that vitamin D has a deep mechanism of action. It acts as a steroid hormone that affects the gene (as opposed to other vitamins). This vitamin directly affects 1000 different genes. Therefore, we recommend frequent and moderate exposure to sunlight and the use of vitamin D supplements in the winter months.
This latest study and the results obtained are very interesting because of its size and structure. This is the first study conducted among a large population and tracking the status of participants for several years. A randomized trial with more accurate results is the next step.
