It is almost as if this is the year for vitamin D.
Every now and then a particular vitamin, medication, food group or supplement becomes a major source of studies and reports. Lately it is vitamin D. The latest research is a European study which suggests that people with low levels of vitamin D scored worse on a test of cognitive ability.
Over 3100 men between the ages of 40-79 were in the study. According to the research, as vitamin D levels fell so did the performance of those being tested. Those over 60 seemed to show the greatest relationship.
Does this mean that vitamin D can help prevent Alzheimers or other forms of dementia? This has not been shown but it is clear that a balanced diet makes sense and vitamin D, at least in recommended amounts, doesn’t seem to hurt
