Low vitamin D levels may damage brain
New research from scientists at the University of Kentucky suggests that low vitamin D levels may affect more than our bones--it could also do damage to our brain and other organs.
The research showed that when middle-aged rats were fed a diet low in vitamin D for several months, they developed free radical damage to the brain and also performed worse in cognitive functioning tests for learning and memory.
The researchers say that vitamin D deficiency is increasing in the US and could have a significant effect on the aging brain. Allan Butterfield, lead author of the paper, recommends that people should try to get at least 10 to 15 minutes of exposure to the sun every day to ensure that vitamin D levels are adequate.
