Immune boosting foods

We are constantly exposed to organisms such as bacteria, viruses and fungi on a minute by minute basis, they can be inhaled, swallowed, or inhabit our skin and mucous membranes. Whether these organisms cause disease is determined by the genetic make-up of the organism in question and the integrity of host defence mechanisms, which form our immune system.

It is well established in scientific research that certain aspects of nutrition such as intake of fibre-rich foods, the health of the intestinal microbiome and omega-3 fatty acids have the ability to influence the immune system.

Immune support by micronutrients is historically reported to be based on vitamin C deficiency and supplementation. It has since been established that the intricate details of the immune system require a balance in multiple specific micronutrients, including vitamins A, D, C, E, B6, and B12, folate, zinc, iron, copper, and selenium. These nutrients play vital roles at every stage of the immune response.
