Vitamin that is found in meat, fish and milk, may prevent memory loss in old age, scientists say. Researchers from Oxford University, in a study that found people with low vitamin B12 six times higher risk of problems in the brain. The results are published in the current issue of the journal Neurology. The study included 107 healthy subjects aged 61 to 87 years. Behind them were observed for five years long. On average, two out of five participants had a low level of the vitamin in the blood. Experts believe that the level of vitamin B12 depends on the diet. In addition, the earlier a deficiency of folic acid (vitamin B9), which were exacerbated by disturbances in the brain. As a result of the five-year study found that vitamin B12 impaired mental abilities, protects the memory and slows down the appearance of dementia. Experts recommend to fill the elderly regularly vitamin B12 and folic acid to their foods used (meat, fish, milk). Of course, this does not solve the problem completely, but it will help to combat age-related changes in the brain without drugs.
