Updated May 27, 2013, 7:16 PMCleanliness is important for good health. We've known this since the pioneering work on microbes of Ignac Semmelweis, Louis Pasteur and Joseph Lister.
Our well-intentioned attempts at germ evasion may have brought on a concomitant decrease in 'good' bacteria.
These well-intentioned behaviors may have led to avoidance of germs and disease, but the unwanted consequence may be a concomitant decrease in the ‘good’ bacteria. Not all germs are bad! In fact, our bodies are dependent on the work of some good bacteria to survive and thrive, particularly in our digestive tracts. Such bacteria in our guts help us digest food and serve to educate our immune system. Achieving ultimate cleanliness today may ultimately result in weaker and less diversified bacterial flora in our bodies, leading to an altered immune system that ‘rejects’ friendly food.
“Everything in moderation” was a saying I grew up hearing from my parents. Have we lost this when it comes to cleanliness? I live in the middle of a large city, and my husband and I frequently joke about how "sheltered" our kids are from the outdoor elements. And yes, both our kids have allergies.
