Saving Your Child from an Over-Sanitized World

Let Them Eat Dirt: Saving Your Child from an Over-Sanitized World

By B. Brett Finlayy and Marie-Claire Arrieta

Algonquin Books of Chapel Hill (2016)

Book Review

Let Them Eat Dirt is a down-to-earth parental guide to the latest research about the role of intestinal bacteria in preventing obesity, diabetes, autism, schozophrenia, depression, anxiety, asthma, eczema, allergies, autoimmune illness, inflammatory bowel disease and irritable bowel syndrome. The book also provides a lot of practical suggestions for parents seeking to promote healthy gut bacteria in their kids.

Most research points to the avoidance of antibiotics during pregnancy and the first few months of life as being most important in preventing the gut-relaed illnesses described above. In addition to recommending that expectant mothers take probiotics and give them to their infants, the authors also emphasize the importance of vaginal birth and breast feeding in transferring maternal gut bacteria to the infant. Where C-section can’t be avoided, they recommend inoculating a newborn with a swab from the mother’s vagina.

Let Them East Dirt also provides numerous tips on increasing the diversity of gut bacteria to maximize immunity. In infants and children, this is done by exposing them to a wide variety of foods and indulging their natural urge to get dirty and put things in their mouths. Finlay and Arrieta believe children are biologically programmed to engage in these behaviors to increase gut bacteria diversity.

In discussing the science behind their recommendations, they point out that only 100 species of bacteria cause human illness, out of a total of 5,000,000,000,000,000,000,000,000,000,000 bacterial species on the planet. They also discuss the essential role “friendly” bacteria play in training the human immune system, as well as the devastating health consequences of disrupting this process through antibiotic overuse.

The part of the book I found most helpful gives useful suggestions for ways parents can work with pediatricians to safely minimize antibiotic use in their kids.

How Gut Bacteria Control Our Health

The Microiome Revolution: Why Microbes Control Your Life

Jack A Gilbert

The Microbiome Revolution provides a brief and user friendly introduction to the essential role the microbiome (the bacteria that colonize our gut) plays in human health. Through their research, Gilbert and other microbiologists have induced obesity, allergies, autism, depression, anxiety, Alzheimer’s, Parkinson’s Disease and other illnesses by manipulating intestinal bacteria in mice. Gilbert contends that specific gut bacteria can even alter behavior.

He stresses that our current obsession with eradicating bacteria (ie prescription antibiotics, antibiotics used on factory farms, antibacterial soap, toothpaste, mouthwash, etc) has dire implications for human health. The human body is an ecosystem in which microbial cells outnumber “human” cells by ten to one. Doctors increasingly view the microbiome as a vital organ, like the liver or kidneys.

Thanks to Gilbert’s crowdfunding site*, his research team has collected the microbiome profiles of hundreds of thousands of people. This baseline has enabled them to identify specific bacterial profiles associated with good health. In general, rural third world residents have the most diverse and healthiest gut bacteria, while urban residents in the industrialized world have the least diverse and the most unhealthy.

Western Medicine: Still Stuck in the 20th Century

Film Review

In brief, Origins is a film about saving the planet by improving your diet and lifestyle. The filmmakers assert that a healthier diet will enable people to think more clearly about the imminent crises confronting civilization. While I totally disagree with the premise – I don’t believe real change is possible without confronting corporate corruption and growing inequality – I liked the film. It offers the clearest explanation yet of the fundamental role of the microbiome* in human health and the rhizophere** in plant health.

Western medicine, as currently practiced, has become totally obsolete owing to its inability to view the human body as a holistic integrated unit. The end result is that roughly half of us are in really poor health. While I disagree with the premise of the film, I’m willing to concede that many of us aren’t healthy or fit enough to tackle major social or political change.

A secondary premise of the film is that we need to fundamentally rethink the way we use technology – mainly because we’re systematically poisoning ourselves through air pollution and toxic endocrine disruptors that mimic estrogen in our bodies. This heavy estrogen effect is a major factor in an epidemic of breast, prostate and other cancers, as well as infertility, obesity and anxiety/depression.

My favorite part of the documentary concerns the microbiome, which turns out to be primary source of our immunity. Owing to the overuse of antibiotics in medicine and agriculture (in livestock feed), most of us have experienced a mass extinction of our intestinal bacteria. This, in turn, plays an even bigger role than toxic chemicals in diseases triggered by inflammation, such as obesity, cancer, type 2 diabetes, heart disease and autoimmune illnesses.

Origins goes on to stress the importance of vaginal birth and breast feeding in establishing a healthy microbiome in infants and the avoidance of antibiotics, antibiotic soaps and commercial household cleaners and toxic chemicals in keeping it that way. Letting kids play in the dirt is another important source of beneficial bacteria. As are are fermented foods and fresh (unprocessed) chemical free foods.

I was also pleased to see the filmmakers brutally debunk the low fat, high sugar, high carbohydrate diet*** Food Inc and western medicine have been trying to sell us for the last fifty years. This is the number one reason half of Americans suffer from “diabesity” (aka metabolic syndrome), even though many of them may not realize it yet.

To their credit, thousands of doctors (according to filmmakers) are taking their patients off GMO foods, resulting in rapid relief of allergies, chronic illnesses and infertility.

I was also pleased to see the comparison filmmakers make between the soil rhizosphere and the gut microbiome. While we’ve been destroying our intestinal bacteria with antibiotics, Food Inc has been systematically destroying essential soil bacteria with pesticides, herbicides and GMOs.

Citing a recent UN study, Origins explodes the myth that GMO technology is the only solution to world hunger. According to the UN, we could double current crop yields in ten years simply by switching to organic farming methods that restore the health and integrity of our soil.

Ignore the background music (I hate documentaries with soppy background music). It’s worth putting up with for the excellent section on diet.

* Microbiome, as defined in this film, refers to the millions of intestinal bacteria that are essential to healthy digestion and immunity.

** The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms.
