This is also from "Sick and Tired" by Young:
"Allergy -- food and environmental. As we've seen, the blood can be overwhelmed by fungus and poisons, severely stressing the immune system. In addition, digestive difficulties often prevent the proper breakdown of protein. Partially digested proteins (not usable by the body) can still be absorbed into the blood, especially when a leaky gut exists. In this form they serve no purpose other than feeding bacteria and yeast/fungus. The immune system sees the faulty proteins as filth and must initiate a clean-up. When bacteria and yeast/fungus feed on (putrefy and ferment) undigested proteins, they produce several toxins, including uric acid. These can be absorbed into the blood, or be produced in the blood by yeast/fungus, which also activates an immune response."
"Since this combination of poor protein digestion with yeast/fungus and their mycotoxins is frequent or ongoing, our janitorial service is constantly irritated, overworked and on edge. Imagine yourself trying constantly to clean house as filth is being tossed in through the windows. These irritations may result in chemical or nutritional sensitivites -- allergic reactions to toher substances, which are called allergens. Allergens may be other foods, airborne matter or chemicals. An immediate or slightly delayed chemical chain reaction creates the various allergic responses we see (but there are some not commonly recognized, such as addictions). The allergy-causing food or airborne allergen does not cause the allergy directly, but only triggers it because immune processes are already compromised. That is, there is a threshold situation: the level of filth, toxicity or acidity has reached a point where the allergen instigates the reaction, but it does not cause the allergic condition."
"The irritation/inflammation reaction ... Soreness, swelling, tearing eyes, runny nose, eczema, etc... are all ways of eliminating acid toxins. Thus, yeast/fungus, whose poisons are acid, may contribute significantly to your hay fever and sneezing. Once the process is under way, the number of offending substances can keep increasing until many individuals become so sensitive to the everyday environment that they must live in isolation or move to another climate. If you had no symptogenic yeast/fungus, it would be impossible for you to have allergies."
Note: This has been my own experience ... my allergies (quite a few) disappeared completely after 2 - 3 months on NaClO2, combined with good hydration and a shift towards an alkaline diet.
