According to a recent article by Michael Pollan in the New York Times Sunday Magazine, “There’s a case for dirtying up your diet” in order to increase your exposure to bacteria. Really? More germs, not fewer? Yes! More germs, please, according to the article, “Some of My Best Friends Are Germs.”
And potluck dinners might be just what the immune system ordered.
Since the introduction of antibiotics, we’ve been on a mission to kill bacteria. Cleanliness, next to Godliness and all that. But the photo on the cover of the Times Magazine’s May 19th issue calls all that cleanliness into question: picture a chubby, healthy, drooling baby nested between the paws of the family dog who is licking drool from the baby’s cheek and lips, introducing the baby to germs and adding to the gut culture that will activate the baby’s immune system now, and for a lifetime to come.
The Pollan article advocates a new appreciation for the bacteria that lives in our gut. Pollan calls this collection of living gut residents our microbiome, or our “second genome,” and explains how these gastrointestinal hitchhikers exert influence as great or greater than the genes we inherit by triggering expression of strengths and weaknesses in our DNA. This mix of microbes activates our immune system, modulates our metabolism, even balances enzymes responsible for mental well-being.
What I took from this interesting read was that taking hygiene to the max may actually limit the ability of the immune system to keep us healthy. Instead, we should aim for just enough exposure to bacteria to keep our immune systems engaged and strong. Additionally, we should be aware of the limiting effects of exposure to antibacterial soaps, hand sanitizers, antibiotics, various food additives and preservatives; these protective products come with a price tag. So we need to weigh the pros and cons of hygiene and consider the point of diminishing returns for our own unique health vulnerabilities.
Similar thinking about germs is popping up in my reading in many unexpected places. In The Extraordinary Healing Power of Ordinary Things by Larry Dossey, MD, a chapter entitled “Dirt” cites a litany of research on beneficial results of exposure to dirt, dirty water, sick siblings, and childhood illnesses – correlating with various reduced incidence of asthma, hay fever, eczema, and even MS, mononucleosis, and other auto-immune disorders.
“All diseases begin in the gut,” per Hippocrates, 460-370 BC. This lead quote in Gut and Psychology Syndrome by Dr. Natasha Campbell-McBride MD, draws lines between gastrointestinal dysfunction and various little-understood neurologic and autoimmune diseases, including autism. These were interesting perspectives I hadn’t heard before.
Over the past several decades our preoccupation with the hazards of germs has resulted in debates over the communal communion cup in churches and the introduction of entire industries dedicated to antiseptic, antibacterial, sanitizing, and disposable products tailored to our fear of germs: DuPont’s Cellophane claimed protection against the deadly dangers of flies, fingers, and food; Listerine antiseptic promised to protect against halitosis as well as “the 17 diseases carried by the hands”; paper and plastic cups, plates, utensils, and containers offer safe harbor from the residue of other people’s saliva.
The proactive power of potluck
A couple years back, I went through the food safety training necessary to become a state licensed retail food producer and Certified Food Manager. I took the training in hopes I could mentor small value-added start-up food businesses that might develop food items to offer for sale at Lanesboro Local Marketplace in Lanesboro, Minnesota. I learned about all the potential food pathogens, the temperature tolerances and food handling practices that minimize pathogen risk, basic sanitation protocols and products, and more. As a result, I’m more acutely aware than ever of kitchen infractions that invite contamination and bacterial growth.
Already a bit of a germaphobe, this training cranked up my reflex to cringe when a friend tasted her potluck dish, added salt, then thrust the tasting spoon back in and gave it a stir. Or licked a finger in the middle of a dishing-up task.
But with the nudge from Pollan and other nutrition-focused advocates and researchers, I’m trying to think outside the Pandora’s box of the pervasive germ pool. I’ve begun to think of potluck dinners as social occasions that not only offer ideal opportunities to learn from other creative cooks, but also to get a gentle health boost. I consider every dip of the finger and lick of the communal spoon a small gift that may arm my gut and activate my immune response against some virus or malady I may now never get.
So, a grateful shout out to all the cooks who’ve licked a finger or otherwise shared your microbiota – and that of your various family members and circle of friends – with me, my family and everyone everywhere who gathers to break bread.
So, what is your thinking on germs?
I like to consider viewpoints from all corners of the food system and consider food issues a little differently every time I read new information. So many approaches to health seem plausible.
Maybe I’ll feel differently about germs at some point in the future. A recent cautionary piece I read stated that one in five of us have compromised immune systems and really need the standards of anti-bacterial hygiene to be held high.
I’m wondering about your take on germs. What do you know that can add to this discussion? Please share your approach to maintaining the health of your gut.
