The immune system in humans and animal is complex, all the more so because it crosses over all tissues. The traditional view has been that the immune system keeps itself in check, and that is mostly the case. However, for some years there has been a development of a neural feedback loop comprehension that helps to answer some of the complex mechanisms and remarkably ties in the role of a nutritional strategy for immune management. This is known as the inflammatory reflex.

The inflammatory reflex, a prototypical neural circuit that modulates innate immunity, is activated by the presence of cytokines or other inflammatory products in tissues that triggers afferent (a nerve that passes impulses from receptors toward or to the central nervous system) action potentials travelling in the vagus nerve. The ascending information is relayed to brainstem nuclei that control efferent (nerves that convey nervous stimulus from the brain to other parts) neural signals in the form of action potentials transmitted back to the periphery via the vagus nerve.

Whilst this may sound complex – few subjects that combine neurology and immunology aren’t… the outcome suggested meets simple strategies, based on complex mechanisms.
