- Recruiting immune cells to sites of infection, through the production of chemical factors, including specialized chemical mediators, called cytokines
- Activation of the complement cascade to identify bacteria, activate cells, and promote clearance of antibody complexes or dead cells
- The identification and removal of foreign substances present in organs, tissues, the blood and lymph, by specialised white blood cells
- Activation of the adaptive immune system through a process known as antigen presentation
- Acting as a physical and chemical barrier to infectious agents.”
What role does nutrition play? Nutrition is a significant trigger! Good nutrition did not start with the advent of nutritional requirements and governmental food guides. That is likely when poor nutrition started. Overly processed foods, the use of artificial preservatives, and the use of chemicals generally recognized as safe are permitted so long as the food was balanced to a nutritional standard. The modern diet tends to focus on the nutrients present rather than the quality and completeness of the food. In processed foods any deficiencies are made up by the addition of single or multiple vitamin, mineral, and amino acid supplements. The evolutionary diet consisted of whole foods that either brought with them the triggers or the precursor’s to activate this ancient code.
Modern nutrition accepts that “if it looks like a tomato it must be a tomato” .Modern advances in food production are related to man’s intervention through the use of herbicides, insecticides, and genetic modification and chemically balanced fertilizers. The ancient innate code benefited all living organisms while the modern code benefits those selected life forms deemed by man to be useful. A conflict is created.
For over one billion years life relied on nutrients derived from carbon, nitrogen and oxygen to provide energy, protein, vitamins, minerals to sustain them Plants as they evolved relied on the soil to provide nutrients and the soil relied on the death of plants and the microorganisms responsible for decay to replenish the soil’s fertility and vitality. Only nature intervened not man. The picture is much more complicated than this as many factors such as climate, the origin of the soils, the amount of rain and atmospheric gases, and the changing seasons also were involved in types of animals and plants which would survive.
