“When in Doubt, Treat the Gut” Elimination Diet, Probiotics, and Stool Testing

GI tract
“Death begins in the colon” –Hippocrates

Modern processed food may be common, but to our bodys this is an extraterrestrial encounter.

Agriculture. In the 200,000 year history of humanity, farming is an astonishing new development. Between 3-11,000 years ago, agriculture popped up around the globe in several disconnected areas: Asia, South America, Europe and the Middle East (“The Fertile Crescent” in modern day Iraq and Syria). What this means is that for more than 90% of our development as a species, humans were not eating grains or or any modern farmed foods. Processed foods with refined sugars, refined grains, preservatives, artificial flavors, etc. are only 50-75 years old. This means that, at most, 99.3% of humanity’s evolution was apart from any processed food.


Historically speaking, the hominids form which humanity evolved ~5 million years old. This makes the development of processed food 99.999% foreign to us. Fast forward to the present. We all are living in a society where processed food has become the bizarre but pervasive normal.

Processed Food

At the same time as grains and processed foods streamed into the food supply, the new norm in modern human health has developed “modern epidemics” including: obesity, diabetes, heart disease, cancers, Altzheimers, Parkinsons, ADD, anxiety, depression, insomnia, indigestion, irritable bowel syndrome, fatigue, headaches, and a host of cancers and autoimmune diseases. These modern epidemics have become so pervasive that conventional medicine considers them a normal and inevitable part of life and aging. That belief is fundamentally flawed.


A growing group of Functional and Naturopathic clinicians are forwarding the idea that the path back to optimal health is largely paved by a return to a natural, ancient, whole-foods diet. Although taking this step represents a drastic shift for most people, it is really a return to our true nature.

It should not really be surprising that although modern processed foods are pervasive and taste good, they are inherently foreign and can be very problematic. No matter what you may be suffering from, returning to a more natural human diet is, by far, probably the most important thing you can do to support your return to natural health. Food is medicine.

Let’s talk about our guts? Out GI tract is an impressive 20-25 feet long. What’s more impressive is that the GI track is, by far, our greatest exposure to the environment.

Doubles Tennis

When flattened out, our GI tracts have 300 square meters of surface area! That’s the size of a double’s tennis court, and 200x more area than our skin.

Our guts are also home to most of the  40 trillion bacterial cells that make up our microbiome –to which we play host. By comparison, an average male has only 30 trillion human cells. When you count the hundreds of trillions more mitochondrial cells (which are basically house-trained bacteria that make 99% of our body’s ATP energy), it’s fair to say that we are not a human hosting a microbiome, we are actually a microbiome hosting a human.


Lets talk about the microbiome: that community of 40 trillion cells in and on our bodies, most of them in the gut. When our guts play host to “unfriendly” microbes (bacteria, yeast & parasites), the result can be chronic immune system activation, leaky gut, and decreased gut surface area, and both GI and systemic inflammation.

A simple way to address many cases of GI distress is to take a strong probiotic. I like the Jarrow brand 50B CFU. If you buy three bottles, they are shipped in a well insulated cold pack.

good and bad bacteria

Modern stressors of noise, traffic, overpopulation, and a constant barage of phone pings and email are also disruptive to our digestion and our guts. One of the primary reasons for this is that the body reacts to these stressors by diverting energy away from our digestive organs and the metabolically expensive hdrochloric acid (HCl), pepsin, and pancreatic enzymes (protease, amylase, lipase, etc.). One way we can begin to get our digestion back on track  is to supplement HCl and pancreatic enzymes with our meals.

Stress, NSAIDS, acid blockers, processed food, pesticides are all things that can cause gastrointestinal inflamation also and decrease the absorptive surface area. This makes the gut “leaky” and allows food, foreign chemicals and microbiome proteins to enter the blood stream where the immune system does its best to protect you from these unexpected invaders. The immune system is quite thorough, often too thorough. Prolonged GI immune activation (i.e. from grains, processed foods, and unfriendly microbiome) is believed to be behind the development of IBD and autoimmune diseases.

Many patients with Gastreesophageal reflux or GERD (AKA heartburn) are told to take antacids like Rolaids or Tums or proton pump inhibitors, such as Prilosec, Prevacid and Nexium, or H2-blockers, such as Zantac, Pepcid and Tagamet. sadly all of these VERY common “remedies” miss the boat. In most cases, the solution to GERD is avoiding adverse food reactions (allergies, intolerances, or sensitivities) and ironically INCREASING the ammount of HCl and active enzymes in your stomach and intestines.

What can be done about the dammage that stress, and improper digestion causes? My first line suggestion is DGL (Deglycyrrhizinated Licorice). DGL lozenges are really effective at soothing an esophagus, stomach and duodenum that have been beaten up by acid or adverse food reactions.

Aloe Vera Gel is also very effective at soothing an enflamed GI tract. Aloe Vera’s constituent mucopolysaccharides, also known as glycosaminoglycans (GAGs), are thought to be its active components. Scientific studies have indicated that Aloe can help to support the body’s own healing processes. In addition, Aloe Vera has been shown to support a healthy digestive system. NOW Foods makes a 200x concentrated soft gel capsule.

Zinc, Mastic gum, and slippery elm are also three potent ways to repair damage from gut inflammation and maldigestion. NOW foods makes a product with therapeutic ammounts of all three of these agents: Uletrol.

The majority of of your body’s immune cells (50%-70% ) live in your gut. Once your gut’s immune system starts reacting to foods, it become like a bad guard dog that not only attacks the food, microbiome and chemicals in your diet, it attacks the gut itself  causing gut inflammation which not only decreases your ability to absorb foods, it promotes leaky gut, new food sensitivities, systemic inflammation. In case you didn’t know, systemic inflammation is at the root of most if not all of the modern epidemics I mentioned earlier–especially autoimmune diseases.


All this is the backdrop for a key primary Functional and Naturopathic intervention: The Elimination Diet. Elimination Diets can be done in many ways, but they always involve removing foods that are potentially contributing to an individual patient’s state of disease for 4-12 weeks, and then reintroducing them one at a time while watching for flareups. A “complete” elimination diet involves reducing food options to a short list of whole foods least likely to be problematic.

In my practice, when I think that an adverse reaction to food (ARF) may be underlying a patient’s symptoms, I often find it most effective to select a more “targeted” elimination of one or more the most likely dietary exacerbates: Wheat/gluten, dairy, sugar, soy, corn, and food additives and preservatives, pesticides of any kind and perhaps the nightshades (tomatoes, peppers, potatoes).

Another way to test for adverse reactions to food is to do a blood food sensitivity test. A true “allergy” to food is mediated by IgE immunoglobulins. These are often, but not always fairly obvious and severe IgE reactions are the classic anaphylaxis: hives, and airway closure requiring a shot of epinephrine. Food “sensitivity” is mediated by the less perilous IgG immunoglobulin, and other more difficult to detect immune reactions to food. Serum IgG testing is an easy way to survey your blood for 90+ foods at once for ~$200. Many patients find this a excellent way to target a trial of an elimination diet.

Genova IgG Food

Here’s how it works: Do eliminate the suspected foods for 4-12 weeks and then sequentially “challenge” the eliminated foods one at a time for a few days each while watching for a return or exacerbation of symptoms such as: headache, brain fog, joint pain, acne, skin rash, acid reflux, loose stools, IBS, anxiety, disturbed sleep, etc. These conditions are all exacerbated by a hyper-activated immune system, and the foreign proteins and chemicals in grains and processed foods can easily overactivate your immune system.

Back to the bugs. One of the other primary interventions I use with patients is Gut probiotics and fermented foods. I am especially likely to recommend probiotics and fermented foods to patients that have more serious gut dysfunction, systemic inflammation, autoimmunity, a weak immune system, a history of a standard American diet (SAD) or taking frequent courses of antibiotics.

For patients with concerted GI issues, I may order a specialized stool test called a Complete Stool Analysis (CSA). For $300, you can learn an awesome amount about your digestion and the community of microbes (both good and bad) living inside your amazing and vitally important GI tract.
