Clean Gut

The Breakthrough Plan for Eliminating the Root Cause of Disease and Revolutionizing Your Health
by Alejandro Junger, M.D. | Harperone © 2014 · 256 pages

The gut. That’s where all the health magic (or challenges!) begins. Alejandro Junger is a cardiologist turned functional medicine doctor who created the incredibly popular Clean Program. We covered his first book Clean and now for a spotlight on the Clean Gut. Big Ideas we explore include symptoms vs. root causes (paint any brown leaves green lately?), how food’s shelf life correlates with yours, your 2nd brain, nutrigenomics, gluten (the ubiquitous poison) and step 1 to cleaning things up (hint: remove toxic triggers).


Before chronic disease, there is inflammation; but before inflammation comes gut dysfunction. Antiinflammation treatments help, but gut repair corrects the problem right at its source.

“My medical practice today is so much more rewarding because of the Clean Gut program, both for myself and my patients. I am no longer a diagnosis-making, prescription-writing machine. Before I even think of making a diagnosis, I immediately look for gut dysfunction. Often it is so obvious I don’t even need any tests. After a twenty-one-day gut-repair program, so many of my patients’ problems are completely gone. There’s no need to order tests of prescribe pills. With an understanding of how the gut gets damaged, how gut dysfunction manifests as a multitude of seemingly unrelated and distant diseases, and, most importantly, how to help the body repair the gut, I was able to help many of my patients restore their true health. Such results led me to write this book. The Clean Gut program is a simple, lifesaving protocol designed to start you on the path to vibrant, lasting, prescription- and disease-free health.

This book is the culmination of the work and research I started when I set out to heal myself. I discovered that the gut is the root of health, and gut repair is the mother of preventive medicine. If your gut is healthy, there are almost no chronic diseases to prevent. For too long we have reacted to symptoms as our first steps in getting healthy. But with this new protocol, we offer a method to strike down disease before it takes hold. We no longer have to get sick to get healthy. With this new program we are able to transform our entire approach to health. Food is medicine, and the gut is the key to a long, vibrant life.”

~ Alejandro Junger, M.D. from Clean Gut

The gut.

That’s where all the health magic (or challenges!) begins.

Alejandro Junger is a cardiologist turned functional medicine doctor who created the incredibly popular Clean Program (and who happens to be Gwyneth Paltrow’s doctor).

Check out our Notes on his first book Clean where he walks us through the basics of his Clean approach. With Clean Gut, we shine a light on our gut and, of course, how to clean it up so we can shine with radiant, vibrant health.

The cornerstone of the book is a 21-day gut-repair program. Check out the book and Clean Program for more details.

For now, I’m excited to share some of my favorite Big Ideas we can apply to our lives TODAY so let’s jump straight in!!

P.S. Check out our Notes on Brain Maker by David Perlmutter—another great book on the power of a healthy gut. Perlmutter is a leading neurologist who connects our nutrition + gut health to our brain health. Powerful stuff.

Symptoms vs. Root Causes (Paint Brown Leaves Green?)

“The reason I say this was my first lesson in good medicine is because after eight years of medical school, six years of training, and another fifteen years of practice, I came to the conclusion that good medicine is very much like good gardening. Imagine you have a tree you love. One day you notice its leaves have turned brown. They will, you understand, soon whither and fall off. Imagine now that you call an expert who, after close examination of the leaves, recommends that you paint them green and attach them back to their branches so the tree can at least appear to be healthy. Everyone would agree that’s crazy. If you want to get your tree truly healthy, you can’t just cover up the problem. You need to get to the root of it. And just like Fermin used to say, the problem is most likely in the roots.”

Alejandro kicks the book off with a story about following his gardener (Fermin) around the house as a little boy as he tended their plants. Fermin would take a quick look at the leaves and then spend the bulk of his time tending to the roots and soil.

Alejandro says that this was his first lesson in good medicine.

He says: “While I was in medical school the trend in modern medicine was to specialize and super specialize. Doctors became experts in one organ or even one part of one organ. More advanced technology helped not only detect problem areas, but also treat them. The advances of science were mesmerizing, and people held the practice of medicine in high regard. The great irony of our success, however, was that we only got better at painting the leaves. We went way beyond gardeners who paint the brown leaves green. We cut out whole branches and replaced them with healthier ones. Or built artificial branches and leaves altogether. We got so good at attacking individual diseases and symptoms we forgot to look at their root causes.”

Painting brown leaves green. Removing whole branches and replacing them with healthier ones.

In short: Dealing with symptoms vs. root causes.

The more specialized the medical community has become, the further away we’ve gotten from a systemic look at the ROOT causes of our issues.

And, of course, the point of the book is that our GUT = our roots.

If we want to thrive, we need to start with a clean, healthy gut.

Let’s take a look at some Ideas on how to do that.

P.S. Another helpful metaphor for the symptoms vs. root causes: Imagine a pot of water that’s boiling. If you take a symptoms approach, you might just drop in a few ice cubes at regular intervals to cool the water down from a boil. If you look at the root cause of the boil, you’d turn off the flame causing the water to boil.

Symptoms vs. root causes. It’s always wise to look at the roots…

P.P.S. Here’s how David Perlmutter captures the power of the gut in Brain Maker: “New, leading-edge science from the most well-respected institutions around the world is discovering that to an extraordinary degree, brain health and, on the flip side, brain diseases, are dictated by what goes on in the gut. That’s right: what’s taking place in your intestines today is determining your risk for any number of neurological conditions…

The digestive system is intimately connected to what goes on in the brain. And perhaps the most important aspect of the gut that has everything to do with your general wellness and mental health is its internal ecology—the various microorganisms that live within it, especially the bacteria.”

A pill for an ill to suppress symptoms is a lot like painting the brown leaves green for a sick tree. It is just bad gardening. And it doesn’t work.
Alejandro Junger, M.D.

Meet Your Second Brain: The Gut (Depressed)

“As the tiny nerve filaments that innervate the neighboring cells join with one another, they form nerves, which are bundles of axons, extensions of the neurons that live in the gut. Amazingly, if you were to isolate these neurons and clump them all together, they would form a mass of neurons larger than the ones in your head. In fact, the brain in your gut is way more active in the production of neurotransmitters than the brain in your head. Serotonin, the neurotransmitter responsible for the feeling of happiness and well-being, is primarily manufactured in the gut—90 percent of it, in fact.”

I’m ALWAYS blown away by the fact that our GUT has more neurons that our BRAIN.

Alejandro shares this in the context of talking about his own health challenges—at one stage at the peak of his medical practice when he was running around all hours of the day and eating poorly, he suffered from depression, irritable bowel syndrome and a bunch of other issues. He was on something like 7 prescriptions to deal with all of the challenges.

When he was diagnosed with depression, his psychiatrist pointed to his head and told him his brain was not producing enough serotonin.

In hindsight, Alejandro tells us, the psychiatrist should have been pointing at his gut.

Remember: Up to 90% of our serotonin is produced in our gut. (Nuts.)

Keep that in mind the next time you consider how to most effectively deal with your or a loved one’s depression.

Start with the GUT!

In fact, most health issues affecting the world’s populace today are the result of a disrupted, damaged gut.
Alejandro Junger, M.D.

Longer Shelf Life = Shorter Your Life

“This will only take us so far, however. There are other, more insidious antibiotics decimating our intestinal flora. These are found in our food. Some of the same antibiotics doctors prescribe to human patients are administered to livestock by the food industry. These antibiotics kill your good bacteria as well. Now include the number of antibiotics the food industry adds to any processed food that comes in a box, jar, bag, tube, or bottle. Many chemicals are added to food during processing to kill any bacteria or funguses that would shorten a product’s shelf life. The food industry calls them preservatives, but in essence they act as antibiotics. Other chemicals, such as coloring agents and texture, odor, and flavor chemicals, also make it hard for good bacteria to thrive. How else would something edible last for years without decomposing? Next time you shop the aisles of a supermarket, remember the longer the shelf life of what you are eating, the shorter yours will be.”

Antibiotics.

Although Alejandro makes it very clear that there are instances in which antibiotics can be life-saving (his own life was saved when antibiotics helped cure him from a double pneumonia infection), we need to be very aware of how much antibiotics we use and the deleterious effects on our gut.

Alejandro tells us that some of his most challenging cases are with patients who have a history of a ton of antibiotic use—particularly earlier in their lives. Part of a longer chat, but while killing the invaders, antibiotics also destroy the friendly stuff in our microbiome that needs to be restored!

For now, let’s focus on the fact that those preservatives that keep food on the shelf longer are basically acting like antibiotics.

The next time you’re cruising through the grocery store looking at all the food in boxes and jars and tubes, remember:

—> The longer the shelf life of what you’re eating, the shorter your life will be.

Let’s stay on the outer aisles at the store and eat the fresh stuff that spoils fast!

Healing the gut is the single most important step we can take to ensure our lifelong health.
Alejandro Junger, M.D.

Nutrigenomics

“I do not mean to oversimplify things. Cancer is the result of many factors. But even genetic factors are connected to the gut. Carrying the gene for a certain cancer does not guarantee that the cancer will develop. Genes can be turned on and off by the conditions in which the cell is living. Nutrigenomics is the science that studies how nutrients, a lack of nutrients, or toxic molecules absorbed from our food can activate a gene that was previously dormant. The conditions that turn cancer genes on, however, are mostly the result of gut dysfunction.”

That’s from a chapter in which Alejandro traces a number of our most prevalent diseases to our gut: from heart disease and cancer to depression and auto-immune disease.

Lots of different symptoms. One primary root. (Echo!) The gut.

Then there’s nutrigenomics—how our nutrition turns on or off certain genes. What a fascinating branch of epigenetics.

Makes me think of Tom Rath—author of Eat Move Sleep (+ Are You Fully Charged? + my favorite kid’s book (was just reading it to Emerson yesterday, in fact): The Rechargeables).

Tom basically lost the cancer lottery. Diagnosed with cancer at 16, Tom discovered that he has a rare gene mutation that shuts off a powerful tumor suppressor. As a result, he lost his left eye and has spent a week in the hospital every year getting tests to make sure his various cancers (in his eye, kidneys, pancreas, adrenal glands, and spine) are in check before getting a new 12-month lease on life.

AND… In the face of those bad odds, he’s THRIVING—a living case study that genes don’t exclusively determine outcomes.

We have the power to influence our genetic expression with every bite we take and every step we take and every good night of sleep we get and every minute of meditation and…

Let’s flip on the good switches and keep the not-so-good switches in the off position. :)

It’s simple really: if you learn about how your gut works and understand how to repair and keep it clean, you will achieve vibrant, long-lasting health.

Gluten: A Ubiquitous Modern Poison

“Most people don’t fully understand how much gluten affects human health. The list of syndromes and diseases associated with gluten sensitivity is endless. It affects all the body’s systems: hematologic, reproductive, neurologic, endocrine, hepatic, rheumatologic, encephalopathic, dental, and cutaneous. …

Gluten is associated with cancers of the mouth and throat, esophagus, small intestines, and lymph nodes. … Gluten sensitivity is also associated with other autoimmune diseases… depression, migraines, arthritis, fatigue, osteoporosis, and anemia to name a few.

With so many scientifically proven or suspected connections to so many diseases, it is tragic that instead of removing gluten from our lives, here in America we put it in everything.”

Gluten. It’s a silent enemy and one of the first things removed from the Clean Gut program.

As Alejandro points out, gluten sensitivity is scientifically connected to a TON of diseases. Knowing this, one would hope we’d REMOVE it from as many things as we can. Alas, the exact opposite is happening.

In Grain Brain, David Perlmutter says: “It is my belief that gluten is a modern poison.”

Gluten is found in grains like wheat, rye, and barley. (And, note, before the agricultural revolution, we ate miniscule amounts of wheat. Now, we eat 133 lbs of it a year. The genetically modified version of wheat we consume today has 20x more gluten than the prior model.)

Gluten is also such a good “binder, filler, shaper, bulking agent, texturizer, and stabilizer” (it’s Latin for “glue”) that it’s found in a TON of other things ranging from hot dogs to ice cream. And, “Most importantly, it is in the comfort foods we love the most, such as bread, pizza, rolls, buns, pancakes, cakes, muffins, pasta, pies, and pastries.”

If you or your family’s health is sub-optimal, experimenting with removing gluten might be a REALLY smart thing to do.

As Perlmutter says: “Remember, if you do nothing else recommended in this book but eliminate gluten and refined carbohydrates, you will experience profound positive effects.”

Removing gluten and other “toxic triggers” is Step #1 in the Clean Gut program:

Discovering that either gluten or dairy is a toxic trigger is an amazing find. Before completing the Clean Gut program, these foods affected you without you knowing about it. Not anymore.
Alejandro Junger, M.D.

Step 1: Remove Toxic Triggers

“Toxic triggers are foods that may taste great but more often than not leave you feeling terrible. They can cause mood swings, indigestion, bloating, and fatigue. They may also trigger an autoimmune reaction. Toxic triggers often promote the proliferation of unhealthy organisms inside the gut. The most common toxic triggers are gluten, dairy, processed sugar, caffeine, and alcohol. Getting clear on your toxic triggers will undoubtedly improve your health and prevent your mood, weight, and energy from yo-yoing up and down. During your reintroduction process you’ll focus on two most common toxic triggers: gluten and dairy.

I can’t stress enough how important it is to identify your toxic triggers. It really is the foundation of building a clean gut and living clean for life.”

So, all that leads to Step #1 of the Clean Gut program: REMOVE TOXIC TRIGGERS.

We need to give our gut a chance to heal. If we’re constantly bombarding it with toxicity, it simply can’t do that.

The most common toxic triggers that are the first to go? Gluten. Dairy. Processed sugar. Caffeine. Alcohol. (Followed by corn, grains, soy, and nightshades.) <— The book walks us through how to go about eliminating those and then reintroducing them to test what triggers us.

What DO we eat? Whole foods. Stuff found in nature and made of one ingredient.

One super simple way the Clean Team tells us to think about it is: “whole foods minus your toxic triggers.”

Finding your toxic triggers is the most important first step in living clean for life.
Alejandro Junger, M.D.

The Guiding Principles for Living Clean

“The guiding principles for living clean for life are clear and direct concepts that have worked for our community and our team. That being said, there is no single right or optimal way for everyone. There are hundreds of programs, doctors, and ‘experts’ who tell us what to eat and how to live. But nothing is more powerful than your personal experience as you test and try out each of these principles. Pick the ones that work for you and modify the ones that don’t. Most importantly, though, if something isn’t working for you, be open and willing to try something new.”

Those are the final words of the book (written by two leaders of the Clean team: Dhru Purohit and John Rosania).

Here are their guiding principles:

  • What Not to Eat. It ALL starts with removing the toxic stuff. Most of the benefits people experience in the first 21 days of the Clean program (and most health programs), come from ELIMINATING the bad stuff. They say it’s like taking tacks out of your back pocket. Makes life a lot more pleasant. :)
  • What to Eat. After removing the bad stuff, we bring in the good. We eat a bunch of the good stuff which helps us “crowd out” the not-so-good stuff. Remember: Whole foods minus your triggers!
  • How to Eat. We want to eat the right food in the right way. Tips: Don’t “food bomb” where you eat a TON of different things at one time and think 80/20: 80% of your plate with greens/veggies + 20% for protein/fat. And, stop when you’re 80% full.
  • Supplement Right. It starts with food and… “Supplements help plug the nutritional gaps that keep us from reaching our health goals.”
  • Understand the Psychology of Clean Living. Notice your emotional triggers and break the cycles of emotional eating. See Habits 101 for some good WOOP if-then planning! :)
  • Move and Chill. As Katy Bowman says, we move less than ever before but we rarely ever completely shut down. We need to MOVE our bodies. And, we need to chill!
  • Create Community. Angela Duckworth tells us that the fastest way to build grit it to join a gritty community. Having support from people who share your goals + values = huge!

Well, that’s a super quick look at this great book.

Think of it this way: the basic template for your long-term health is whole foods minus your toxic triggers.
