Not having enough vitamin D in your diet can kill your immunity, leading to various diseases, including the autoimmune ones, according to US-based top health professionals. “The most dangerous thing about not having vitamin D has to do with your immune system because vitamin D helps build your T-cells,” Dr. Eric Berg said on his Instagram channel.
T-cells are a type of white blood cell called lymphocytes which help your immune system fight germs and protect you from disease. Vitamin D deficiency increases the risk of infections and autoimmune disease, which are signs that the immune system is affected. Apart from the T-cells, vitamin D also affects the immune system by influencing the function of B cells, dendritic cells, and macrophages.
How does vitamin D deficiency cause autoimmune diseases? Dr. Berg explained that autoimmune diseases can be caused by a failure of T-cells, which are not able to distinguish unhealthy or infected cells from healthy ones. A new study conducted in mice shows that vitamin D deficiency led to the development of T cells that elicit an excessive immune response against healthy tissue.
T-cells are also involved in facilitating an immune response against microbes and the elimination of cells that might be infected or have cancer. How is vitamin D linked to autoimmune conditions? Studies say vitamin D potentially modulates T-cell function in early life and, subsequently, the risk of autoimmune conditions. Vitamin D gets converted into its biologically active form in the body by the enzyme Cyp27b1.
According to scientists, genetically engineered mutations in both copies of the genes result in an ability to produce the active form of vitamin D. Without vitamin D, the size of the thymus gets reduced and a lower number of T cells in the blood indicates a higher risk of autoimmune diseases. Health benefits of vitamin D Getting enough vitamin D helps the growth and development of bones and teeth.
It also provides improved resistance to many diseases. A few other benefits include: Regulating and improving mood According to experts, vitamin D plays an important role in regulating mood and decreasing the risk of depression and anxiety.
