There are a multitude of stressors in our environment. Our surroundings are bombarded with chemical pollutants in the water and air, petrochemicals are introduced into our food supplies through pesticides, and we are exposed to electromagnetic pollution, seasonal light changes, and sudden variances in barometric pressure. Concomitantly, we suffer from emotional stress, excessive or insufficient exercise, and the effects of nutritional or biochemical imbalances from eating denutrified, allergic, and high fat foods.

The Loading Theory describes how these factors interact with and compound each other to break down the immune system, resulting in conditions such as chronic fatigue, allergies, autoimmune disease, persistent viral infections, yeast overgrowth, malabsorption, parasitic infections, and more advanced degenerative diseases such as cardiovascular illness, diabetes, and cancer.
