Make
Of Your Gut a Herb Garden (Part I)
Our evolutionary history designed us for life on the savannas of east Africa...
Back
in Victorian times, it was the common wisdom that one should empty the
bowels once a day. Instinctively those practical Victorians felt that it
is not good to have toxic waste hanging around in the body. But as time
wore on into the 1920’s those ideas fell out of favor: constipation
seemed to be the natural condition!
But
anyone who has spent time with tribal societies will be aware that they
defecate frequently and copiously. As early as 1939 the explorer-doctor
Weston Price, MD, observed how such societies enjoyed many health
benefits as a result. In the 1970’s Dr Denis Burkitt reinforced
Price’s work with his own observations on African villagers. For the
first time the colon’s contents were thought of as a living thing:
“biomass”.
Even
so, ten years ago, when I first wrote about gut health in my book Natural
Eating, conventional medicine still thought of the colon as a
nuisance. If they thought of the colon’s contents at all, they called
it “excrement” and thought of it as proto-sewage. Our knowledge has
come a long way since then, and it reinforces my insistence on how the
right biomass is a key element in good health. I made a feature of it in
my latest book Deadly Harvest.
Now the evidence is pouring in.
Until
now, scientists had only identified some 500 species of bacteria in our
guts. I had always thought that this is a gross underestimate:
researchers had only been able to count the few species that they knew
how to grow under laboratory conditions. Now Les Dethlefsen PhD at
Stanford University, using ground-breaking DNA techniques, finds that
there are at least 5,000 species of bacteria in the colon – that’s
TEN times as many as previously thought!
The
Battle of the Bugs
These intestinal microbes live, for better or for worse, on the food
residues we send down. Send down the wrong residues and the bad bugs
take over; send down the right residues and the friendly ones thrive.
Why does that matter? Over the millions of years, our bodies have come
to depend on the benefits that the friendly bugs bring us. For example,
without them our immune systems don’t develop properly and we will be
deficient in essential nutrients such as vitamin K and propionic acid.
Furthermore, good bacteria fiercely defend their citadel (our colons)
from the bad bugs that are forever battering at the gates.
Over
100 TRILLION bacteria inhabit a healthy gut. We now know that the
balance of power between the species is critical. But what have got
today? Bad bugs have invaded and infested the colons of people on the
classic western diet. Right in the heart of our bodies we are harboring
a vicious, evil-doing enemy. What does it take to drive out the hostile
forces and welcome in the good guys? I’ll come on to that later, but
first let us look at some of the latest discoveries about the benefits
that a properly functioning bio-mass brings us.
Infection
Fighting
Dr. Gerard Eberl, at the Institut Pasteur, shows that good bacteria
communicate with the immune system to generate lymphoid tissue. This
tissue produces antibodies which are vital agents in fighting bad
bacteria and infection. Without them the bad bacteria and infections get
a foothold.
Next
month:
I will explain about how the mischief created by bad gut bacteria
contributes to inflammatory bowel diseases, autoimmune diseases (like
Diabetes type I, asthma and allergies), osteoporosis, cancers and heart
disease.
