If you are not getting enough vitamin D, you may have the higher risk of dementia and Alzheimer’s disease. A new study conducted by the researchers at Rutgers University and University of California Davis, and led by Joshua Miller, the researchers tried to find out further whether the disease is linked to ethnic groups who have low levels of vitamin D.
About 400 people participated in the series of studies for a longer period. Their blood levels were measured annually for five years for vitamin D.
At the initial stage of the study the vitamin D level was 61 percent, which is below recommended levels. Those who were suffering from dementia showed lower levels of the vitamin.
It was found the African-American as well as the Hispanic people had lower levels of vitamin D. They also had lower cognitive scores compared to the white volunteers.
According to the authors of the study, much of the vitamin D comes in our body from our diet, sunlight and supplements.
Those who are black may not be able to take the advantage of the sun and so lack in vitamin D. However, it is not yet known whether the shortfall can be balanced with the help of supplements.
As of now the reports are conflicting about the effects of vitamin D in making out bones stronger.
One study is expected to be published in 2017 and it may bring more clarity. About 26,000 people are being studied in four countries to know the effect of vitamin D on cancer, heart disease, diabetes and more.
