What root cause likely leads to severe IgG food sensitivities in clients?

Enhanced intestinal permeability, often referred to as "leaky gut," is a key factor that can lead to severe IgG food sensitivities in individuals. When the intestinal lining becomes more permeable than normal, it allows larger food particles, toxins, and microorganisms to pass through into the bloodstream. This abnormal passage can trigger an immune response, resulting in the production of IgG antibodies against specific foods. Over time, this can lead to the development of food sensitivities characterized by inflammation and various gastrointestinal and systemic symptoms.

In contrast, insufficient nutrient intake, excessive exercise, and low dietary fiber intake may influence overall health and digestive function, but these factors do not primarily create the conditions for increased intestinal permeability. While they are important considerations in a holistic view of health, they do not directly cause the same immune responses related to IgG sensitivities as enhanced intestinal permeability does.
