A Primal Primer: Leaky Gut

By Mark Sisson
79 Comments

Small IntestineAfter I mentioned it in last week’s 10 Principles of Primal Living (Finally) Getting Mainstream Media Coverage post, several readers emailed asking about leaky gut. What is it? How do I know if I have it? Why should I care if I have it? What do I do if I have it? And so on. Turns out many and maybe most people have but a vague idea of what leaky gut actually means.

Today, I’m going to fix that.

In most popular conceptions of human physiology, the gut exists primarily as a passive conduit along which food travels and breaks down for digestion and absorption. It’s where bacteria hang out and digestive enzymes go to work. It’s a “place,” an inert tunnel made of flesh and mucus. Lots of things happen there but the gut itself isn’t doing much.

Except that the gut serves another very important and active role: as a dynamic, selective barrier between us and the external world with all its nasties. Dynamic in that it responds differently depending on what’s trying to get through. Selective in that it’s supposed to let in good things and keep out harmful things.

Lining the gut are epithelial cells whose cell membranes fuse together to form protein complexes called tight junctions. The tight junction is the doorman. These are the dynamic, selective parts of the gut. Like the doorman, the tight junction’s job is to discern between what belongs inside and what doesn’t. What gets passage through the gut lining into our body and what is denied. Tight junctions keep out pathogens, antigens, and toxins while admitting nutrients and water.

That’s in a perfect world, though. Sometimes the doorman shows up to work drunk. Sometimes the doorman can’t turn down the $100 bill enfolded in a handshake. Sometimes the doorman lets the pretty girl and all her friends cut in line. Many variables can affect the doorman’s ability to discern between who belongs and who doesn’t. And the same goes for intestinal tight junctions.

How do you know if you have leaky gut?

Everyone’s gut is a little leaky, a little permissive if not downright permeable.

One way is to take an intestinal permeability test. You drink a solution containing a pre-measured amount of mannitol and lactulose, two indigestible sugars. You collect your urine over the next 6 hours and measure the amount of excreted mannitol and lactulose to determine how much permeated through your gut.

Another way is to measure levels of blood zonulin, a reliable marker of intestinal permeability. You might have trouble convincing your doctor to order this one.

You can also look at the list of conditions commonly associated with elevated intestinal permeability. If you have any or all of them, you may have leaky gut. Put another way, if you have leaky gut, you may be at a greater risk for some of these. What are they?

Celiac disease: When gluten is broken up into fragments in the gut, those fragments induce the release of zonulin, which tells the tight junctions to become more permeable. This happens to everyone whose guts come into contact with those gluten fragments, but the effect is enhanced in people with celiac. Their gluten-induced leaky gut is way more leaky than it should be, and it stays leaky long after the gluten has been gone. In fact, before direct testing for gluten antibodies and intestinal damage became widespread, a common test for celiac used to be the very same intestinal permeability assessment I just mentioned.

Inflammatory bowel disease (IBD): Patients with Crohn’s disease, an inflammatory bowel disease characterized by severe inflammation of the gut lining, tend to have leaky gut. And in general IBD, which includes Crohn’s and ulcerative colitis, high intestinal permeability precedes the development of the disease.

Irritable bowel syndrome (IBS): As discussed yesterday, IBS patients often show increased gut permeability. Some researchers suggest that leaky gut leads to the kind of chronic, low-level inflammation that characterizes IBS.

Asthma: There is a high prevalence of leaky gut in people with moderate to severe asthma, though researchers aren’t sure whether it’s a cause or consequence of the asthma.

Food allergies and intolerances: The transportation of the food allergen across the gut lining appears to be a necessary step in the development of a food allergy, and a 2011 review concluded that an overly leaky gut facilitates this transportation and leads to the inducement of allergy.

Autism: Children with autism and their first-degree relatives tend to have abnormal gut permeability, suggesting a gene-environment component to autism. This is present in some, but not all people with autism.

Rheumatoid arthritis, ankylosing spondylitis, and other autoimmune diseases: Both RA and AS have been linked to leaky gut, and the connection may hold for other autoimmune diseases, too.

Obesity and metabolic syndrome: Both obesity and metabolic syndrome are often linked with intestinal permeability, and a recent paper explores all the potential mechanisms that might explain the link.

Depression: By some accounts, 35% of depressed patients have leaky gut.

Eczema: Going back as far as 1986, researchers have found leaky gut to be common in eczema patients.

Interesting, huh? Leaky gut really gets around. It may not be the whole story, and some of these connections may be coincidental, but plausible mechanisms exist for most of them and I’m confident that fixing leaky gut will improve many seemingly disparate health problems.

Plus, even if it wasn’t the proximate cause of your health problems, leaky gut probably isn’t helping you get better and you should try to fix it. Multiple feedback loops which make teasing apart cause and effect nearly impossible also make it possible to step in the middle of the loop(s) and break it up.

Leaky gut: what it is, how to know if you have it, and what to do about it: http://ctt.ec/5f8B4+

What should you do?

First, avoid things that might cause it.

Gluten. Gluten begets gliadin releases zonulin induces leaky gut. I discussed this in the celiac section above, but it’s important to reiterate that gliadin has this leaky effect on every gut, not just in celiacs. Celiacs just get it worse than non-celiacs.

Stress. Stress can directly induce leaky gut (PDF) and stress can take many forms, as we all know. Bad finances, marital strife, unemployment, too much exercise, lack of sleep, extended combat training, and chronic under-eating all qualify as significant stressors with the potential to cause leaky gut, especially chronically and in concert.

Too much alcohol. Ethanol increases intestinal permeability by changing the gene expression of the proteins involved in tight junction function. If you do drink, be sure to follow best practices and definitely do not drink on an empty stomach. Alcohol also depletes zinc, which is a crucial pro-gut nutrient.

Poor sleep habits. In one recent study, mice whose circadian rhythms were disrupted were more susceptible to liver damage and alcohol-induced intestinal permeability.

NSAIDs. Non-steroidal anti-inflammatory drugs like aspirin and ibuprofen can be helpful in certain situations, but they are far from benign. One of their worst and most pronounced effects is leaky gut.

Then, take proactive steps to improve gut barrier function.

Take whey protein isolate and glutamine. Both supplements have been shown to reduce leaky gut in patients with Crohn’s disease.

Try resistant starch and other prebiotics. Whether potato starch, green bananas/plantains, mung bean starch, inulin powder, jersualem artichokes, leeks, pectin, or apples, start eating RS and other prebiotics on a regular basis. They increase butyrate production (which reduces intestinal permeability) and support the growth and maintenance of healthy microbial populations.

Take probiotics and/or (preferably “and”) eat fermented food. Prebiotics are important, but you also need to provide the right gut bugs if you’re deficient. You can do it with both supplements and food. L. rhamnosus and L. reuteri supplements reduce leaky gut and improve symptoms in kids with atopic dermatitis. L. rhamnosus also helps restore the gut barrier in kids with acute gastroenteritis. In rats with leaky gut, yogurt improves gut barrier function.

Get adequate sunlight and/or take vitamin D3 supplements. Vitamin D helps protect against injuries to the intestinal lining, while a vitamin D deficiency promotes intestinal permeability and inflammation.

Get enough zinc. Oysters, red meat, supplements – zinc supplementation reduces leaky gut.

Make broth, eat gelatinous cuts of meat. I don’t have any scientific references for this one, but it’s such a staple piece of advice in the “healing your gut” scene that it’s worth including. Plus, oxtails are magic, and science can’t quite explain magic just yet.

Exercise intelligentlyIntense, protracted exercise induces leaky gut. This is normally transient and totally manageable, but if taken to the extreme as in chronic cardio, exercise-induced leaky gut can become a chronic condition. The same goes for any kind of chronic exercise. Even too much strength training can probably do it, though you’d have to do a ton of volume without much rest. Meanwhile, moderate exercise improves gut barrier function. The tried and true triumvirate of lifting heavy things, walking lots, and sprinting occasionally is the safest bet.

Check out a free Solving Leaky Gut webinar this Thursday. If you want to hear direct from the experts who’ve helped patients solve and cure leaky gut and many of the aforementioned health issues related to it, you’ll want to attend the webinar this Thursday, May 8 at 9 PM Eastern. It’s part of a larger package called Solving Leaky Gut that gets way deeper into the condition and offers specific, proven tips, tricks, and strategies for improving your gut function, reducing food intolerances, and boosting immune health.

If all this stuff seems daunting and far-reaching, that’s because it is daunting and far-reaching. The gut affects nearly everything. But look at the bright side: fixing your gut may be the key to good health for many of you. It’s actually quite empowering. Don’t you think?

Well, according to this, gluten is best avoided in general, even in people who are not celiacs.

Since I cut wheat out of my diet I’ve found that when I do indulge in donuts or beer my gut isn’t happy. And recently I’ve found that beer and sweet pastries just don’t have the allure that they used to have. Personally I think that’s my gut shaping my decisions.

“Well, according to this, gluten is best avoided in general,even in people who are not celiacs.” That sure appears to be the intended implication, considering the way things are phrased – which seems biased to me, though: Gluten has a “leaky effect on every gut” (reiterated and heavily emphasized), ergo: avoid gluten (“blanket deduction”). versus Alcohol “increases intestinal permeability” (translation: same thing really – but this time the wording is more abstract, and there is no particular emphasis on the fact that “no one is safe,” which results in a comparatively negligible “visceral impact factor” of the statement), ergo: avoid… Read more »

IMOH, Mark addresses wheat and gluten well. Don’t Americans consume excessive ammounts of wheat when compared to the Mediterranean cultures? Rice is something most people I know TYPICALLY AVOID. Personally, since I need the starch, replacing bread with rice has helped me so much!

Karl
Karl

Do Americans “consume excessive ammounts (sic) of wheat” at the expense of other foods, on average? Probably. That is, however, irrelevant with regard to the point I was trying to make, namely that the chain of argumentation this article presents is inconsistent: If one reasons that nutritional components which have “a leaky effect on every gut” should be avoided completely, it follows that both gluten and alcohol are strictly verboten; conversely, if one stars out from more of a “bird`s eye perspective,” thus arguing that hitting the sauce can be A-okay depending on dose/context/individual circumstances because there is more to… Read more »

Quote from Karl “In my opinion, the fact that gluten-containing grains are a part of the diet in several of the “Blue Zones” – i.e., are eaten by some of the longest-lived healthy populations we know of – as well as several “Mediterranean Diet” intervention trials indicate that the “aggregate impact” of gluten consumption may be (relatively) benign (for at least some people), depending on dose and context”

It could also be a genetic thing.

Karl

Sure it could (although the Bayesian probability appears low, considering, among other things, a)how widely scattered the respective “Blue Zone”-populations are geographically – unless one were to invoke convergent evolution, which would in turn undermine the basic “Paleo premise” -, and b) that there are Mediterranean diet intervention trials including gluten-containing grains which document net health improvement ); correlation does not equal causation, yadda yadda yadda. My main point is that exactly the same goes for the epidemiological data implying that moderate alcohol consumption can be part of a healthy nutritional pattern, or even improve on it – so why… Read more »

Americans eat too much bleached gluten. It’s the bleach that causes the problem because it kills beneficial bacteria while feeding candida. Candida is the real reason for leaky gut and everything about wheat feeds candida so people have in their minds that wheat is the problem. It’s not, it’s just a symptom. In ancient times, even as late as 200 years ago the only, “yeast,” bread that anyone ate was sourdough. For thousands of years this was the case. So the bread had lactobacilius bacteria in it. And I read in the bible they used to dip it in wine… Read more »

Same here…. ive been doing alot of testing on my self… the gluten protein looks like the yeast protein.. you may find you also feel better eating less corn, potato etc as these feed yeast.. you find most gluten free people switch to these flours yet never get better but feel better not eating gluten

Dean Ellis

It’s because they are only treating the symptom. Gluten intolerance is a symptom of a larger problem. That problem is candida overgrowth. Fix the candida overgrowth and they will be cured and then able to once again eat gluten.

Most people who cut out gluten actually increase their sugar intake to improve flavor which makes the candida problem worse. It’s why they still feel bad if they eat gluten. The candida is still there. Fix the candida the the gluten intolerance goes away.

I’m living proof of this.

The info on that intestinal permeability test being a ‘common’ way to diagnosis celiac is wrong – the article linked to is from 2000 – newer, more accurate tests are available and have been for years. The gold-standard for diagnosing celiac is a blood test to look at gluten antibodies, followed by an intestinal biopsy to confirm and assess damage. The intestinal permeability test won’t tell you if you have celiac- just if your gut is especially permeable or not.

Otherwise, very interesting!

Abijah L.

The paper in question suggests the use of lactulose and manitol as a screening test for celiac. However, there are direct antibody test available in the 21st century, so why bother? Also there aren’t any validated and commercially available tests for zonulin level, so even if you could convince your poor doctor to order the test, there wouldn’t be anything to order. Plus it appears that the half life of zonulin is pretty brief, so getting a good level, if there were a test, would be a bear.

There is a test called Array 2 or Intestinal Permeability Screen from Cyrex Labs. The screen tests for, Actomyosin IgA, this tells if the leak is through the cell itself. Occludin/ Zonulin IgG, IgA, and IgM, this tells if it’s through the tight junctions. The last three are Lipopolysaccharides (LPS) IgG, IgA, and IgM which refer to time, endotoxins found in bacteria etc. There is also a test called Array 4 or Gluten Associated Cross-Reactive Foods and Foods Sensitivity. There are 5 cross reactive foods to gluten, the others are sensitivities. I’ve seen plenty of these tests. Not everyone has… Read more »

I don’t think I have a leaky gut but I’ve been primal for 4 years. I have so many close family members that think it is normal to have some of these issues. It isn’t normal at all! Why can’t more people see that? Are we becoming so used to being sick and tired that sick and tired is the norm? My niece is high functioning autistic. What is the harm in trying to change diet?

I am right there with you in frustration.

Some people resist change. They just don’t want to because it stresses them out to think about the effort it would take for them to do it. I have family that are the same way, they’d rather complain than do something about it. But that doesn’t mean I won’t keep making the same suggestions, cause I think eventually they’ll try them.

watch out for anti-biotics as well as over exercising, stress, alcohol etc
I think the best fermented foods are kimchi, sauerkraut and unflavored yogurt. Probably best to steer clear of those fruit bottomed, colorful packaged little yogurts that are more sugar and corn starch than beneficial yogurt.

Here’s how a leaky gut and food allergies set off my rheumatoid arthritis: the food I’m allergic to is seen as toxic. The toxins enter my bloodstream (largely undigested) through my leaky gut. The bloodstream carries those toxins to all my muscles and joints, causing debilitating pain, stiffness, and inflammation–to the point where I can hardly move at all. 4 days in bed and tons of Benadryl later, I’m better, but not back to normal–that takes another day. I used to endure this on a daily basis when I was 3, only no Benadryl to fall back on. I wish… Read more »

‘You collect your urine over the next 6 hours and measure the amount of excreted mannitol and lactulose to determine how much permeated through your gut.’

Going on this test, does this mean that people with leaky gut are excreting more vitamins / nutrients through their urine? I ask because when I eat liver, my urine turns a freakish fluorescent yellow. Is this normal, or is this a symptom of leaky gut through Vitamin A malabsorption?

Krissy
Krissy

Super yellow pee usually caused by excreting B vitamins. This is common in everyone. I take a B complex daily because of previous fatigue issues, and I notice when I am feeling fatigued everything is fine on the pee front, but when I feel normal and upbeat etc my pee is bright yellow from 2-4 hours after I take the supplement. I drink 3L+ of water a day so I know it’s not that. Liver is super high in Bs so it’s likely your body is just getting rid of the vitamins you don’t need!

A lot to consider…and I continue to be confused by the idea of “chronic cardio”…I love running distances, but at a very manageable pace and I wonder what effect that has if any? It’s obviously individual to some degree but since it keeps coming up (at least on this website) I wonder if there is any way to actually tell if you have crossed over into chronic cardio beyond moderate exercise.

Elevated cortisol levels,oxidative stress,and free radical production are things you could get tested but I have a couple of sisters who run all the time who used to be “strong looking” with those famous curves men tend to be especially fond of.

Anyway I linked over?! to your sight and you definitely look healthier than Demi Moore. Do you do any resistance training? When you do anything at a “comfortable” level you’re inviting muscle atrophy into the picture over time. Also replacing a 10 mile run for a half hour weight lifting session just one day a week will help your race times.

Sorry, my response wasn’t very thoughtful. Your cardio recovery might be hard to measure using soreness. Maybe declining performance would be an indicator? Take an extra day of rest and see if performance is better?

Obviously, I’m not too worried about my lazy ass doing any chronic level of exercise!

Michele, your confusion is warranted, seeing as the whole “chronic cardio”-conundrum is actually based on an extremely vague concept, as far as I can tell: It emphatically declares that “too much endurance exercise is bad for you,” but doesn`t offer a reliable definition of “too much”: Some proponents are convinced that any mile you run is one too many – that is demonstrably BS, as mountains of data demonstrate; others are more moderate, and content themselves with recommending no more than approximately 20 miles of weekly running (James O`Keefe is a relatively well-known representative of this subgroup) – the evidence… Read more »

Michele, I don`t think you need to worry, considering your “very manageable pace”: If we go by Mark`s own definition in his “Definitive Guide to Low Level Aerobic Activity,” moderate exercise “involves working at 55 to75 percent of your maximum heart rate,” the upper limit of which corresponds to “a medium cardio workout at the gym” for “a fit person” (and, somewhat ironically, encompasses the bulk of the training regimen most contemporary endurance athletes adhere to – not to mention that the whole “chronic cardio” concept is a rather dubious hypothesis at this point, anyway – take a look at… Read more »

Shannon

Thanks HB. I suspect that it was gluten that was causing the most grief for my son. The leaky gut was allowing gluten into his bloodstream, which was causing neuro-inflammation when it hit his brain. No gluten = no inflammation = full cognitive function restored! Now that we’ve healed his gut, he can eat gluten without ill effect. He is a completely different kid. Thanks for your interest and positive feedback. Shannon

I had a small patch of skin rash near my ankle for at least a year. Various skin cremes had little effect. After eating Paleo for a little while, I realized it healed. I’m assuming it was autoimmunity from leaky gut. I have other symptoms of autoimmunity, and they serve as reminders of how well I am taking care of my gut. No testing needed.

Bovine colostrum works very best, even better than L Glutamine for healing a leaky inflamed gut. Immune Tree colostrum and Surthrival colostrum are quality colostrums. Pricy but worth it. Avoiding too much insoluble fiber is a good idea as well. Too much insoluble(undigestible) fiber irritates the walls of the intestines. This is why people eating a high “heart healthy” whole grain diet often suffer from bloating, gas, intestinal cramps, IBS, chron’s disease. Bone broths are great gor gut health as the gelatin helps repair ligaments, joints, muscles.

I use one made in Australia by Solutions4health.
It’s called “Oil of Wild Oregano”

What about Biohealth Diagnostics, Enterolabs and Cyrex? Did anyone try them? So may labs so little money? LOL They all test your gut.

Wow. Just, this is all blowing my mind. In the last year I cut out gluten and (through a couple accidental ingestions) realized it was causing my migraines. But now, if I get it, suddenly I get full-body joint pains. That’s new. Now recently I, out of nowhere, get the exact same reaction I get from gluten (migraine + joint pain) when I eat dairy, lactose really. Cheese is okay, but not frozen yogurt, cream, butter… I’m starting to think the real problem is my gut. What would be REALLY exciting, past the idea of maybe someday losing all the… Read more »

Seems like the solutions you provided are similar to the solutions for acne..
Not a coincidence.

Mark, super disappointed (and I’m not alone) that you recommended this webinar…a complete letdown. No new info, just an hour and a half of advertisement. Anyone who subscribes to you wants or needs to hear this elementary explanations.

I agree, My husband and I sat down to watch the webinar. We learned nothing. You had more information in your blog post than they provided for us. We could have watch a couple episodes of the free thyroid sessions or even gone to bed on time.

I had the same experience as Jen and Regan. In addition to the shameless way they proceeded to sell to the audience, they didn’t even seem prepared for the talk. The fact that it was a ridiculously long presentation (it was nearly two hours before their cherry picked Q&A) really wasn’t helping them.

Mark, that is a very good post, thank you!

I have chronic constipation. May it be caused by leaky gut?

And what about non-gluten grains? If I want to heal my leaky gut, is it necessary to avoid all non-gluten grains (like rice, millet, oat, etc.) and potato, tomato as well?
Please, help! 🙂
Thank you!

A great way to clear out the wrong pathogens and clear the slate for the good bacteria is to take Immunoglobulin Y which is the antibodies found in chicken egg yolk. While fighting off pathogens a hen’s immune system generates millions of antibodies and also puts them into the developing egg yolk for the chick to have when it’s born. Chicks obviously don’t breastfed and need an aggressive defense right away. The antibodies are also effective for roughly 450 different human related pathogens. This is another reason why eggs are good for you. However when eaten with the rest of… Read more »

Thank you, that is very interesting!
And what if I drink that egg yolk in my coffee in the morning? On an empty stomach?

Does anybody know the answer : is it necessary to avoid all non-gluten grains, and potato, tomato as well when healing leaky gut?

You would get some IgY benefit from egg yolk but it’s limited for four reasons. Plus you would be getting a rather strange testing coffee. I personally do not like the idea of eating raw egg yolk; Reason 1) When the protein enters the stomach (each egg yolk has 2.6 grams of protein) then it will release acid to unfold the protein and pepsin (an enzyme) to cut up the protein into amino acids. IgY is a ‘functional protein’ by that I mean it has a specific function which is to bind to a pathogen. But it’s a protein and… Read more »

But then, I don’t understand, why you wrote in your previous comment:
” While fighting off pathogens a hen’s immune system generates millions of antibodies and also puts them into the developing egg yolk for the chick to have when it’s born. …. The antibodies are also effective for roughly 450 different human related pathogens. This is another reason why eggs are good for you.”
But thank you for your answer
I registered for the seminar and it was very useful, thanks!

Sorry typo in Reason 3) I meant 50 milligrams of IgY for two capsules of Vector450.

I just learn something new and need to make a correction to my earlier post;

In Reason 1) I stated that protein is broken down in the stomach by acid and pepsin into amino acids. That’s not correct. Protein is broken down into peptides in the stomach which are broken down in the small intestine by peptidase enzymes into amino acids which are absorb by the lining of the small intestine into the bloodstream.

Anna, You are right, I seem to contradict myself when I wrote that the Immunoglobulin Y (antibodies) are one of the reasons eggs are good for you but then I also wrote that when you eat eggs the digestive process in the stomach will breakdown the Immunoglobulin Y. However, like a lot of things in life…it depends. The Immunoglobulin Y is a tough immune protein and some can get through into the intestine but the more protein in the stomach (big meal with lots of eggs and bacon) then more could be digested. My company has extracted and purified the… Read more »

Ok, so I’m really new to all this diet, nutrition and digestion stuff. Perhaps that is why this post left me more confused than anything. I understand the word “gut” as just a short-hand for “gastro-intestinal tract,” which includes the stomach, the small intestine, and the large intestine. They are three entirely different organs which perform entirely different functions. But isn’t what is called a “leaky gut” a problem with the small intestine only, which is where most of the nutrients in the food we digest are absorbed? And my understanding is that the vast majority of our intestinal flora,… Read more »

I eat fermented foods, take zinc, am fit like Mark is but younger (mid 30s, 6’2 175) but I have thought about how I might have “leaky gut” for some time now. I have to use psyllium precisely because I’ve had loose stools for a few years now.

I think there is some balance thing going on here, possibly bacterial or yeast (candida?) but it’s odd because I’m such a healthy person otherwise.

What should I do? Take that mannitol test? It would probably just confirm what I’m already suspecting. Mark, any tips?
