The digestive system needs to process and deliver nutritional resources and energy
supplies to the whole body. A stressed digestive system is less able to process
energy and nutrients for the rest of the body. It will also be less able to repel
harmful invaders and more prone to disorders such as irritable bowel. Once the
immune response is triggered in the body (as evidenced by raised IgG antibody
levels) the body feels that it is ‘under siege’ thus hoarding supplies, storing
fluid and increasing weight. It takes an overall approach to undo the damage caused,
and indentifying food intolerances is an important part of this process.
