Helps Keep the Immune System Healthy
Vitamin A is essential for sustaining the body’s natural defenses, which include mucous barriers in the eyes, lungs, genitals, and gut that help trap bacteria and other infectious agents. It also plays a role in the formation and role of white blood cells, which assist in capturing and removing bacteria and other pathogens from the bloodstream. As a result, a vitamin A deficiency can increase one’s susceptibility to infections and delay recovery time during an illness.
The immune system serves as the body’s defense mechanism. Without it, the body is incapable of protecting itself against bacteria, viruses, and other harmful organisms. It is a vast network of proteins, tissues, cells, and organs that spans the entire body. A fully functional immune system can differentiate between healthy tissue and foreign substances. If it detects an undesirable substance, it launches an immune response, or a complex attack designed to shield the body from invaders. It also detects and eliminates dead and faulty cells.
In autoimmune disorders and allergies, the immune system misidentifies healthy tissue as unhealthy and initiates an unwarranted attack, resulting in uncomfortable or dangerous symptoms. Getting enough vitamin A in the diet promotes a healthy and fully functional immune system.
