Vitamin D found to be the most readily available means of preventing senile dementia
Researchers at the University of Exeter have summarized the results of a decade of research into the effects of vitamin D on the development of dementia. This disease is considered one of the major problems of developed mankind, as up to 40% of the population suffers from it at an advanced age. There are many causes of cognitive loss, but now there is a strong argument that vitamin D deficiency is one of them.
Vitamin D deficiency is caused by three basic factors. First, rapid urbanization has caused people to spend a significant amount of time indoors, without access to direct sunlight, which helps the body produce this vitamin. Secondly, improper nutrition – people don’t eat healthy foods, but what they can afford. And third, there is a factor in the APOE-e4 gene, which leads to the inability to get vitamin D other than through the intestines, which was the basis of the study.
Researchers followed a group of more than 12,000 people aged 71 who showed no signs of dementia at the start of the study. Some were given vitamin D supplements, others were not, and the study continued for ten years. Among those who received the vitamin, only 40% developed dementia. Whereas 75% of elders without this vitamin in their diet got the disease.
We can’t say that vitamin D is a cure-all and protects against dementia, but it significantly reduces the risks of this disease. More precisely, the deficiency of this vitamin increases the risks, while at its normal level they will be minimal. Taking the vitamin in the form of supplements is much easier and cheaper than other methods of combating dementia, the doctors conclude.
