Study Demonstrates How Low Vitamin D Levels Damage The Brain

December 2, 2013: 12:00 AM EST
A new British study shows that vitamin D, which is important for bone health, is also important for the health of other tissues and organs, including the brain. Middle-aged rats fed a diet low in vitamin D for several months developed free radical damage to the brain, and many different brain proteins were damaged as identified by redox proteomics. The rats also showed a significant decrease in cognitive performance on tests of learning and memory. The researchers advised people whose vitamin D levels are low to eat foods rich in vitamin D, take vitamin D supplements, or get at least 10-15 minutes of sun exposure each day.
