According to the Swedish daily newspaper on October 19, scientists from Karolinska Hospital (Sweden), the University of Eastern Finland and the Finnish Health Research Institute conducted a survey of 270 elderly people during the eight years. year. The results found that subjects with relatively high levels of vitamin B12 had a lower risk of Alzheimer's disease than those with low vitamin B12 levels.

The results of the study showed that lack of vitamin B12, although not the only cause of Alzheimer's disease, is one of the main causes of the disease.

Previously, international scientists have also studied the relationship between vitamin B12 and Alzheimer's disease, but this is the first time scientists have conducted large-scale research over a long period of time.

According to the Swedish Health Agency, among the elderly in this country, 5-10% suffer from a lack of vitamin B12. The main reason is because the ability to absorb vitamin B12 in the elderly decreases with age.

In addition, research has shown that microwave ovens greatly disrupt vitamin intake in food. During the rotation of food in the microwave oven, more than one-third of the vitamin B12 in food is destroyed.

The results of the study were published in the latest international medical journal Neuropsychology.
