Vitamin D deficiency is known to be a risk factor for a number of diseases including multiple sclerosis and rheumatoid arthritis.
But, this new study explains how Vitamin D may be involved.
Vitamin D affects our DNA through something called the vitamin D receptor (VDR), which binds to specific locations of the human genome.
Sources for Vitamin D include exposure to sunlight and foods such as fish, cheese, and egg yolks.
