Know the Important Role of Nutrition in Improving the Immune System

The immune system or the immune system is the body's ability to fight infection and eliminate the work of toxins in the body.


How the Immune System Works:

  1. Bacteria and other pathogens can enter the body through wounds on the skin/mucosa surface.

  2. The natural immune system will respond by releasing factors that trigger immune cells to the injured/sick area.

  3. Neutrophils which include white blood cells will secrete substances that can kill and decompose pathogens / germs.

  4. Neutrophils and the body's natural immune system called macrophages will eliminate pathogens by "digesting" or what is called phagocytosis.

  5. Macrophages produce hormones called cytokines that trigger the immune system and tissue repair.

  6. The work of the immune system will last until the pathogen/germ dies and the process of repairing damaged tissue is complete.


Nutrition is a substance that comes from food that has been digested and processed in the body so that it becomes a substance that is useful for maintaining and forming body tissues, regulates physiological systems in the body, produces energy and protects the body from disease.
