Our bodies are subject to more foreign substances today than have been experience by all of our ancestors combined. Daily we are bombarded with endless toxins in a variety of forms. Genetically ,the human body is programmed to be a very adaptive organism. Natural evolution allows for changes in food and in environment to be absorbed and accepted slowly over the ages. But with the advancement of the scientific age, changes are thrust upon us far faster than our bodies can adjust.
More time is needed for the adaptation process to be effective.
When these changes are forced upon our immune system without the eons of time that are necessary for the body to adapt and cope, certainly it can be seen that we are overloading it with toxic materials. The body cannot deal with these toxicities. This onslaught of insults weakens the immune system and reduces the immune response. It can only deal with the viral and bacterial invaders that it has developed the ability to handle. Currently we know that cancer, herpes, AIDS, candidiasis, food and chemical allergies, lupus, mononucleosis and arthritis are just some of the conditions to inflict the human race that are directed to an altering of the immune response.
