The body’s ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround cells, as well as the cells’ ability to ‘read’ these chemicals. Cells are highly sensitive. In fact, the immune system can be triggered by the presence of just one foreign molecule or ion. Yet researchers don’t know how cells achieve this level of sensitivity.
