The results were quite astounding; the researchers found that regardless of their age, elderly Chinese with lower vitamin D levels at the start of the study were twice as likely to experience cognitive decline over time. The study only lasted two years, so being low in vitamin D rapidly speeds up brain aging in elderly people.
