Why are allergies becoming so common?
Dr. Miller detailed a prevailing theory -- one that cannot be accepted as scientific fact just yet, but one that many experts think is exemplar. Basically, the way modern humans live has changed the microbes inside of us, microbes that, at one point, helped us deal with outside substances. Like peanuts. And it all has to do with micro-organisms (a community of 'bugs' called micro-biome) living inside our body.
"In you and on you, are more 'bugs' than there are cells in your body. There are 100 trillion in your gut alone. We gather these throughout life. We're simply living cleaner lives now. And if you don't gather these 'bugs' at the appropriate times, or get the wrong ones, it starts an immunodeficiency, which manifests itself as a hyper reaction to certain things -- like peanuts," he said. "It's referred to as the hygiene hypothesis."
Essentially, our modern, Purell-infused, germ-fearing lifestyles keep more germs away, and change the germs we have. Which can be a good thing, obviously, but it also messes with our bodies' inherent construction. And keeping children away from things like peanuts in fear of a potential allergy might only contribute to allergenic symptoms.
