A recent experiment has shown that when animals were fed GMO foods in reasonable amounts, it caused very gradual organ damage and immune system damage. Gradual is significant isn’t it, especially if we start eating genetically modified soy, corn, canola, dairy and potatoes at an early age? (Experimentation on humans seems to have been done on a much wider scale outside the laboratory).
The immune system (http://www.healthsystem.virginia.edu/uvahealth/adult_allergy/system.cfm) becomes active when the body is under stress. When the physical, emotional or chemical stress is on-going, over time it can become hypersensitive and over-react – allergic.
Solutions? Yes there are, and some are immediate. Avoidance of sources of stress often costs nothing except making up your mind. And now, a complete all in one physical exercise warm-up cool down and workout that avoids immune system stress is being democratized: http://www.bodyfitlife.com/site/1305099/page/489707
