The role of Nutrition in the Immune system functions

Poonam Lakra, Indu Nashier Gahlawat


The immune system in our body is a complex network of cells that defends the body against infection and reduces the risk of degenerative diseases. The immune system has two functional divisions: the innate and the acquired. Adequate nutrition is an important determinant of the immune response. Micronutrients contribute to the body's defense by supporting physical barriers i.e. skin and mucosa, cellular immunity, and antibody production. Vitamins A, C, E, and zinc are helpful in enhancing this skin barrier.  The vitamins A, B6, B12, C, D, E along with iron, zinc contribute to the protective activities of our immune cells.  Inadequate intake of these vitamins and trace minerals may lead to suppression of immunity which leads to more chances of infection. Studies have indicated that adding the deficient nutrient back to the diet can revive immune function and resistance to infection.
