Diet and cognitive impairment

A U.K. study of 1,766 older adults has found that low levels of vitamin D are associated with cognitive impairment. The researchers took blood samples to measure people's vitamin D levels and gave them the Abbreviated Mental Test to assess attention, orientation in time and space and memory. Even taking into account co-existing illness older adults with the lowest levels of vitamin D were more than twice as likely to be impaired as those with the highest levels.
