Food Sensitivity Tests vs. Elimination Diets – with Dr. Peter Kozlowski

Food Sensitivity Tests vs. Elimination Diets - with Dr. Peter Kozlowski

Food sensitivities are known to cause health problems that can go undetected for years, and it can be challenging to navigate the barrage of information online. There are allergy tests, food sensitivity tests, the elimination diet, intermittent fasting, and many more options. But which of methods is the proper way of addressing food sensitivities to heal the gut?-In this episode, Dr. Peter Kozlowski and I tackle these questions in-depth and will help you discover the best ways to solve your food sensitivity issues. As Dr. Peter says: “The first step to healing your gut is removing food sensitivities!”

Dr. Peter Kozlowski uses a broad array of tools to find the source of the body’s dysfunction: he takes the time to listen to his patients and plots their history on a timeline, considering what makes them unique and co-creating with them a truly individualized care plan. Currently he works with patients online and in person via his Chicago, Illinois and Bozeman, Montana based offices.

We address these questions:

Are elimination diets effective?

Is an elimination diet or food sensitivity test better?

What is the Mind-Body-Gut Connection?

How important is therapy in healing your gut?

Can intermittent fasting help heal your gut?

What is causing SIBO?

Should you stick with the low fodmap diet?

How do you eliminate SIBO?


Dr. Peter Kozlowski: I could eat a bagel every day for breakfast and feel fine, but I suffer from eczema, migraines, and my body’s reacting to it. I’ll never figure it out. That’s what makes sensitivities so dangerous to me.

Background Speaker: Are you struggling with bloating, gas, constipation, and fatigue, but don’t know what’s causing these problems. The gut health reset podcast with Dr. Anne-Marie Barter, dive deep into the root causes behind these issues that start in the gut. This podcast will give you the knowledge you need to heal and reset your health.

Dr. Ann-Marie Barter: Today on the gut health reset podcast, we are talking about elimination diets, and if they are an effective way to figure out your food sensitivity. Also, if food sensitivity tests are the gold standard, or if elimination diets are the gold standard, how your emotional health affects your gut health and what to do about it, the benefits of intermittent fasting, why food sensitivities have become so common and are pervasive in our society today, as well as if low FODMAP diets are effective for the treatment of SIBO, and what is an elemental diet? Today my special guest is Dr. Peter Kozlowski and he is a functional medicine doctor who uses a broad array of tools to find the source of the body’s dysfunction. He takes time to listen to his patients, plots their history on a timeline, considers what makes them unique and creates individualized care plans. He has an office in Chicago, as well as Bozeman, Montana.

He did his residency in family practice but started training in functional medicine as an intern, under leaders in the field like Dr. Mark Hyman, Deepak Chore, and Susan Bluhm. He is also the author of Unfunc Your Gut.

Hey Doc, it is so great to have you here today. Thank you so much for joining me and I am super excited to dig into gut health with you.

Dr. Peter Kozlowski: As am I, thank you so much for having me on. It’s an honor.

Dr. Ann-Marie Barter: Totally yes. So, you talk about elimination diets in your book and if they’re effective. So I‘d like to dive into that first.

Dr. Peter Kozlowski: Yeah, absolutely. So my book is definitely focused on gut health and the first step in healing your gut is to make sure that you don’t have any food sensitivities. When your body reacts to food, there are three reactions you can have. You can have allergies, you could have celiac disease and you can have sensitivities. Different types of immune responses are created with each one. Allergies are IgE antibodies, celiac is IGA antibodies and sensitivities are IgG, your chronic antibody.

Allergies and celiac, I always tell my patients, are easy because the reaction happens right after you eat the food. So it’s immediate and you don’t doubt that you’re allergic to peanuts or dairy or something like that. There’s also good lab testing. So you can go get your blood drawn or skin testing and identify allergies.

The regular medical community believes in allergies and celiac. Then you have sensitivities, which is basically all that I work with, from those three. The biggest reason that sensitivities are so dangerous in my opinion, is the reaction is delayed hours to days after eating the food.

So I could eat a bagel every day for breakfast and feel fine, but I suffer from eczema, migraines, joint pain, and I go to my doctor and I get pills for this, pills for that. I keep eating a bagel every day for breakfast and my body’s reacting to it and I’ll never figure it out and that’s what makes sensitivities so dangerous to me.

The other big thing is that in my experience, IgG food testing is not reliable. It is typically just like the best marker of leaky gut. Most people that do that testing show up with a log of what you’ve been eating for the last three months. So to me, the gold standard is an elimination diet. An elimination diet is 21 days of removing the 14 biggest defenders and then re-introducing them one by one using a tracking journal.

The other most important thing that I want people to understand about an elimination diet is why is it 21 days? Did we just make that number up? It’s based on half-life. Everything in your body has a half-life. Whether you drink alcohol, take prescription meds, your hormones, toxins, everything has a different clearance time. That’s why some meds you take four times a day. Some are once a month. The half-life of IgG antibodies is about 21 days, 21 to 23 days. So if I’m very reactive to gluten and I had gluten today and I have a hundred antibodies floating around if I don’t have any gluten for 21 days, that antibody count drops in half to 50.

When I eat it again on day 22, my immune system, if it’s created a response against that food, will attack and I will get symptoms. I might’ve done an elimination diet because of migraines, but when I reintroduced gluten, I might get abdominal pain or I might break out in a rash. The symptoms can be anything because it’s inflammation in the body and inflammation in the body can go anywhere. So 21 days of removing the foods, re-introducing them one by one, two days at a time to me is the gold standard for identifying food sensitivities, which to me is the first step in healing your gut.

Dr. Ann-Marie Barter: I 100% agree. I do not love food sensitivity testing, food allergy testing, I think it’s exactly true. You know, you hand somebody a sheet and you say you can eat one hundred of these 500 foods because you’ve eaten these foods. It seems to be foods that they’ve eaten in the last month. I completely agree with that point. I thought that I was the only one that saw, so I’m glad to hear you say that.

Dr. Peter Kozlowski: I’ve been in private practice for seven years and studying functional medicine for ten. I’ve never ordered an IgG food panel, but I’ve probably recommended thousands of elimination diets.

Another issue with them is they’re not cheap. They’re expensive and then I’m usually wanting to test someone’s gut or toxins or other things. Just from a financial standpoint, I’d rather have you invest the money in something that actually gives us information that you can’t gain just from doing an elimination diet and more reliably.

Dr. Ann-Marie Barter: I agree. I agree. So what happens with the mind, body and emotional connection and how does that relate to our gut? 

Dr. Peter Kozlowski: That to me is the big secret that I reveal in my book. I’m going to give a spoiler. It is that your mental, emotional, spiritual health is the key to your gut health. I’ve learned that through my own story and from working with patients, because I’m a perfectionist. So I only think about the people that don’t get better.

I have tons of people that are doing great. I don’t think about them, but the ones that aren’t getting better are the only ones I think about. I’ve tried to figure out what’s the difference? Why can I have 10 people with SIBO, treat them the same or similarly in five, get better and five don’t?

What I’ve discovered is that it’s mental, emotional and spiritual health. You can call it depression, anxiety, stress, trauma, but I really liked just mental, emotional, and spiritual health. The reason why that is the key to your gut health is that your gut and brain are connected.

Your gut has its own brain. It’s called the enteric nervous system. There’s a nervous system that surrounds your gut. That’s made up of 200 and 250 million neurons. It’s more than in your brain. That nervous system is connected to your brain by your vagus nerve. Your vagus nerve runs from the brain to your gut, heart, lungs.

The vagus nerve is carrying signals back and forth from the gut to the brain, the brain to the gut. The vagus nerve runs on your autonomic nervous system, which is your automatic nervous system. That nervous system has two responses. It could be either in sympathetic mode or parasympathetic mode.

Sympathetic mode is fight or flight. Parasympathetic is rest and digest. The analogy that I like to use now is I live in Montana now, and if I’m out hiking and I run into a bear or a mountain goat, that’s chasing me. I want to run away. My sympathetic nervous system is activated. The blood goes to my brain, my muscles, and I escape.

When I’m sitting by the campfire at the end of the night, and having a meal and I’m relaxed, that’s rest and digest. Right? Well, what’s going on in our society, people are living as if they’re running from a bear 24/7. We wake up, we go straight to our phone. We see our text messages, our emails, we check the news….. what kind of traumatic things are happening in the world.

 We’re off and running, right? The rest of the day usually just gets worse. When you’re living in that sympathetic response, you’re shutting down your stomach for making acid. You will not produce stomach acid. If you don’t produce stomach acid, you can’t digest protein. You don’t kill off the bad bacteria you’re being exposed to. You don’t absorb vitamins and minerals out of your food and you don’t activate the rest of your digestive enzyme. So, low stomach acid happens from the sympathetic response. Then you also shut down your microbiome. On a stool test, I warned my patients. I can see how stressed out you are based on your microbiome. So certain bacteria are suppressed on a stool analysis when someone’s been living under chronic stress. I talk about this with all my patients at the first visit about the mental, emotional, spiritual part.

This is when huge red flags, stop signs go up. They’re like, no, I’m fine. I don’t have any issues. And they will gladly follow whatever diets, supplements, tests I asked them to do, but in working on whatever trauma has happened or relationship issues, it’s a no-go.

The sympathetic nervous system shuts down your digestion, shuts down your microbiome, and then everything starts going wrong. You end up with SIBO, dysbiosis, and then usually by the time people have made it to me, it’s an auto-immune disease. It’s some kind of chronic neurological disease, high blood pressure, and we’re trying to reverse it.

I feel like that point is lost in social media and on the internet. Everybody talks about the right diet. What’s the best diet? What are the right supplements? What do you have growing? And then this is just information overload. So chapter one of my book is titled, “have you ever misdiagnosed yourself using the internet?”

I go through a story of Googling abdominal pain and where it took me and most people that have read it have laughed out loud in front of me. It’s pretty cool, but it’s funny because it’s true. You can, within two clicks, convince yourself you’ve got cancer or anything else….it’s shocking.

So probably the best health advice I can give someone that pretty much nobody follows through with is every time you want to get on the internet to read about a condition or what might be wrong with you, try meditating instead. See what happens with your gut health, with your chronic disease health, with just your overall wellbeing.

That I guess is a summation of the gut-brain connection and why it’s so important.

Dr. Ann-Marie Barter: Going into that mental, emotional piece. Do you feel like meditation is enough when there’s been major trauma?

Dr. Peter Kozlowski: No

Dr. Ann-Marie Barter: Okay.

Dr. Peter Kozlowski: Every person that comes through that comes to see me, I encourage them to get a therapist right away. There are different types of therapy, specifically what my patients have had the most success with, who have a trauma history is EMDR therapy. So I plant that seed right away. I stress it as the most important part of your health, the mental, emotional, spiritual part, but it’s also the hardest part for me to help someone with because they’re there for the gut testing and diet and toxins and hormone balancing and all of that.

It’s just not enough time. The other biggest hurdle I think is that there are so many modalities out there, which is amazing. You have to find what’s right for you. Right? That even goes with a therapist or a functional medicine doctor. I might have a lot of great reviews, but you might hate me.

You might not like me. I love my therapist, but she might be terrible for you. So it’s that journey of figuring out what’s the right piece. For me, I’ve been working on this for 10 years, personally. My personal story is that I’m in recovery. I used to be a binge drinker and my trauma was being a first-generation American.

My parents are from Poland. I was born in the US but I had a great life. My parents gave me everything they could, but inside I never felt good enough. I never felt like I fit in. I always felt awkward and I created the trauma. When a therapist introduced that to me, I was like, this is ridiculous.

This is not an issue for me and it turned out to be a major issue for me and how I masked it was with alcohol. It made me comfortable. It made me social, and not care. Then the biggest lesson that I learned that burned me is I’m very much a checklist person. So I have goals.

I write them down and then I cross them off as I accomplish them. I went through recovery. I went through treatment. I did everything. I got a therapist. I put in the work and then everything was great. So I stopped doing all of it and what happened is I relapsed and that’s when I learned that mental, emotional, spiritual health for me to work on is an everyday decision.

I have to wake up and make a decision. I’m going to focus on this today because if I put in a few days without it, I’d go right back to the way I used to be, despite all the work I’ve put in. So there’ll be exercise. I noticed my mood just changes if I go a couple of days if I’m injured and I can’t work out.

I do a gratitude list every day; me and my wife. I will typically take a walk in the afternoon and we always do three things we’re grateful for. Sometimes that’s just the fact that I have a desk or a microphone or the sun’s out. Sometimes on a really bad day, it’s a great reminder. Meditation is difficult. So many people quit because they say they’re not good at it. The biggest thing that I learned about meditation is there is no such thing as being good at it. You can talk to people who have meditated for their whole lives and some days are great, some days are terrible. And by terrible it’s like your mind is just all over the place, but you still get the health benefits from being in that space.

So, with meditation, there are so many different types. For me, I prefer guided meditation. I’ve gotten really into the app called Calm. They’re quick, they’re easy and I prefer that, but then there are different types for different people. A tool that I’m exploring more is heart rate variability.

As a way to basically train your vagus nerve so that there’s nothing that’s more effective for healing your gut, than that. I think that just like for me in recovery, the most important part of it is just accepting that there’s an issue, right? Which for so many people is so difficult. And I understand that, I’ve been through that and I get it.

Once you accept that there’s something happened when you were a kid or that you, didn’t feel this way or that way and you realize there’s an issue, then you can’t go back. You can’t ever really un-know that. Then it’s up to you to kinda work on it.

Background Speaker: Hey, this is Dr. Ann-Marie barter. Have you ever spent hours searching for the right supplements to heal your body? And when you finally found them, maybe you weren’t sure it was a brand that you could trust or if the products were safe. After hearing about these issues, time and time again, I decided to put together a complete store of supplements for healing and supporting your gut at There are supplements for constipation, thyroid health, gut health energy, and so much more. There are bundles created for sleep support, pain support, histamine support, and the list just goes on and on. These supplements I use personally or I’ve handpicked because they’ve worked time and time again on countless cases in the office. On the website, you can see what ingredients we use to put your mind at ease. If you visit and use the promo code PODCAST to get 10% off your next order. So what are you waiting for? Go visit and get 10% off your supplement bundle. Ciao. And now back to our episode.

Dr. Ann-Marie Barter: First off, thank you for sharing your story. That’s pretty raw and I think that takes a lot of courage to share that. I do want to dive into the next part of this, which is why we are so sensitive to foods? Where did that all come from?

Dr. Peter Kozlowski: I believe that it’s because of what we’ve done to our food supply. Through the hybridization of wheat that started in the 1960s to now the genetic modification to where over 90% of soy and over 90% of corn in the US are genetically modified.

Then you take animals like cows that used to roam around grass fields, and now they’re stuck in pens, eating hay, or sometimes some of these genetically modified foods. So what’s happened is the proteins of these foods have changed, right? They changed them. That’s what they did. In some people, which I think when you have leaky gut, it’s more common when those foods get into your body, the immune system is waiting and because the proteins have changed in some people, the immune system identifies those foods as foreign and attacks. So the top five offenders are gluten, dairy, soy, corn, eggs, and there are years of evidence that they’ve been altering those foods. Changing them because food sensitivities weren’t prevalent 40 years ago. It’s escalating year by year.

Dr. Ann-Marie Barter: Why do you feel like intermittent fasting is an important part of a lifestyle to incorporate?

Dr. Peter Kozlowski: I think the biggest thing that I learned about it is: I never wanted to do it myself because I love to eat. I was like, I’m not going to do that.

I’m fasting today. I fast on Mondays and Fridays now. So for me, it was just the mental block of, I can’t survive for 24 hours without eating. I was never a big fan of fasting because I never really saw the benefits of it. Most people that came to see me, had been doing 16 hours.

That is not enough and proper intermittent fasting should be 24 to 36 hours. The whole point of fasting is to activate gluconeogenesis, which is your body using stored sugar to create energy because you’re not putting anything new in. That process doesn’t ramp up until hour 20.

That’s why I think a lot of 16-hour fasting fails and it’s the biggest tool for people that are losing weight. It’s a great way to lose weight. I don’t do it for weight loss, but I do it for my hormones. It improves my testosterone and improves my growth hormone. It improves the way my insulin works. It improves my metabolic rate. So things that I would want for long-term health are achieved. It’s kind of funny to me because it’s so simple, just don’t eat, but it’s so difficult too. It’s funny to me, that it’s just that simple: just don’t eat.

Dr. Ann-Marie Barter: What benefits have you seen with intermittent fasting, having maybe fewer food sensitivities, and better gut health? Have you seen anything great with that?

Dr. Peter Kozlowski: One of the reasons it would help your gut health is we talk all about the microbiome, right? All of us have three to five pounds of bacteria growing in our microbiome.

That bacteria can be good, which is probiotics or that bacteria can be bad, which is dysbiosis. That bacteria can overgrow the wrong parts of your gut, which is SIBO. When you’ve got an imbalanced microbiome, your gut bacteria are alive. They eat fibers and sugars and they only eat when you eat.

If you don’t eat, they don’t eat. So if your microbiome is imbalanced, what’s a great way to start healing? That is to not feed it and that is one of the biggest benefits. SIBO is the most common condition that I treat and something like fasting is gonna help that.

Dr. Ann-Marie Barter: How does it help SIBO?

Dr. Peter Kozlowski: By not eating the bacteria.

Dr. Ann-Marie Barter: So how long do you need to fast to kill off SIBO? We have something like the elemental diet and whatnot. So how long do you think you need to do that for it to be completely effective?

Dr. Peter Kozlowski: You’re right. I call it the elemental diet, my nuclear option. I don’t like to start people on it. I’ve had a handful of people that wanted to do it. For those listening that aren’t familiar with it, it’s a liquid diet for 14 to 21 days. The elemental part is basically like you’re using a supplement protein that has protein fats, carbs, and it keeps your nutrition going while your digestive system is not being activated, so nutrients are just going straight into your blood.

Like I said, the way I would approach SIBO is using natural antibiotics and natural herbs. Sometimes I use antibiotics, regular ones from the pharmacy when my patients request them.

Usually, a typical antibiotic approach would be two weeks, and an herbal approach could be nine weeks or longer. If you’re going to go the extreme route and just not eating, that’s a great way. Everybody that I’ve seen do that, the SIBO goes away. It’s so difficult for a lot of people, we can work out a plan where you’re taking your herbs and supplements five days a week. If two days of the week, you’re not eating, you’re doing fasting, then that’s a way that you can cycle the week to kind of really throw off the bacteria.

Dr. Ann-Marie Barter: Do you like to use a lot of low FODMAP diets for SIBO cases?

Dr. Peter Kozlowski: In my book, we have mostly elimination diet recipes, but also low FODMAP recipes. Then we have a combination which we call the “cause plan”, which is an elimination diet that’s also low FODMAP. The reason that we came up with that, and I have to give the credit to my life coach. She’s the one that came up with it. What you’ll see in SIBO patients is; if you don’t know they have it and you  start an elimination diet; a lot of times they can get worse. Because their diets changed to where they’re eating more FODMAPs, which are fermentable foods. They’re the favorite foods of the gut bacteria.

If you’re eating more of those foods and you have SIBO, you’re going to feel worse. That’s another thing that we just learned over time from working with people; why is someone, emailing, calling, and saying they’re getting worse and worse with elimination.

That component, a lot of times, can be correlated with that. They probably had SIBO and that they were feeding the problem. So SIBOs tough because every practitioner has a different approach to it and we use what we’ve been trained in and what we’ve seen work with people.

I know that there are people that argue against the low FODMAP diet. I’ve seen a hundred percent of the time seen people do better when they are doing treatment as well as the low FODMAP diet. I think one of the most interesting things that I’ve seen is, I’ve had a number of patients over the years that get better just by stopping their probiotics and eating more low FODMAP. That’s one of the big things I wanted to put in my book is to get that information out there is; in the general population if you tell someone you’ve got abdominal pain, bloating, IBS, they usually tell you to get a probiotic and to eat more fiber.

Those are the worst things that you can do for SIBO. I can think of countless people that have cried in my office because they say, so you’re telling me everything I’ve been doing for the last two years, three years, five years has been backward and I say, “yeah”. Low FODMAP to me is a crucial part of treatment but it’s also not a good long-term diet. I want people to be on a low FODMAP diet, as short as possible, get the SIBO in remission, and then you’ve got to start eating probiotics again, to feed your large intestine, your gut microbiome. If you’re starving that, then you’re going to get other issues.

Dr. Ann-Marie Barter: I think that’s the concern I have seen with low-FODMAP. A patient will come in and they will be gluten-free, dairy-free, low FODMAP, low histamine, and they’re eating seven foods. That doesn’t diversify your microbiome either. I think that people feel good and so they want to keep doing what makes them feel good. It’s years later, they’re still on the same diet. Have you seen that?

Dr. Peter Kozlowski: Yeah, absolutely. I talk about that in my book; that I would rather have someone eating at McDonald’s twice a day than being so obsessed about following a strict Candida diet or a strict low FODMAP diet. At the end of the day, what I believe in the most for our guts is our mental, emotional, and spiritual health.

If eating ice cream every day makes you relax, I would rather work around that with you, than you eating five things a day, which I’ve seen many times. I’ve had a lot of patients that I say this to. For example, Candida is the one that kind of sticks out the most. That, that one’s been around the longest.

There’s so much information online that people have convinced themselves that you can never get rid of Candida unless you follow the strictest diet. You have to be perfect, otherwise, Candida will never go away. That’s not true. You can follow a crappy diet, even if you’re following the right treatment, and there’s a good chance, it’ll go away if you’re relaxed, right? When you’re not relaxed, when your sympathetic nervous system is activated, what happens? You release cortisol. What does cortisol do? Elevates your blood sugar and suppresses your immune system. What is Candida’s favorite environment?

A suppressed immune system and sugar to feed off of. So the diets I think are important. I just really try to gauge with my patients what’s realistic for you, right? A lot of times I work with college students or high schoolers or adults where they say “I can’t do it.” Then I say, “then forget it. Let’s try without it and see where we get. I don’t need you to be freaking out about every meal that it’s like the perfect quantity, the perfect food, perfectly prepared with the right oil. You can go nuts.”

Dr. Ann-Marie Barter: It’s exhausting. I’m just thinking back as you’re talking, it is exhausting, I think because the control is so great. You’re right, there is a huge sympathetic dominance. How can you heal that state? So what percentage of the population do you think has SIBO? Do you think the root cause of the SIBO is primarily from our overstressed, over-committed lifestyles?

Dr. Peter Kozlowski: I think that is one of the biggest contributing factors. It’s hard for me to say what percent of the population has SIBO? I know that in my practice, the people that come through to see me, it’s at least 50%, if not more. On that point, another thing that I’ve learned over the years is that there are people who have SIBO that don’t have any gut symptoms.

Which also sounded nuts. You have to have gut symptoms, right? You’re bloated, you have abdominal pain. Then I was stuck with a woman who had chronic canker sores. And I suggested; let’s test for SIBO cause we were just desperate and it came back positive, no gut symptoms. We treat her, she emails me; I haven’t had a canker sore in two weeks. The majority of people do have your classic, IBS symptoms like bloating, pain, constipation, diarrhea, but a lot of people don’t and they have systemic symptoms. That’s a big thing to consider and SIBOs, where it’s tricked me before, is the person can’t have it because they don’t have any guts symptoms.

Dr. Ann-Marie Barter: For all the listeners out there who have had chronic SIBO. They say I’ve had a chronic SIBO infection, I’ve been on a low FODMAP diet, I have taken the herbal antimicrobials…what’s kind of your next step for these folks?

Dr. Peter Kozlowski: If they’ve done antibiotics, then we try herbs. If they’ve done herbs, then I look at what herbs did they use and we try to change the herbs. Sometimes we’ll extend out the herbs. If that’s failed through multiple courses, then, elemental diet. If that fails, people don’t like this, but that’s when I suggest, you got to go in and, and work on mental, emotional, and spiritual treatment.

For me, that was like rehab, but there are rehabs out there that are just for life, for people that don’t end up with an addiction issue. I know that SIBO is a relatively new condition and maybe there are treatments that we’ll still learn about, but that’s been my experience and, usually, when a patient comes to see me, they fill out 40 pages of intake paperwork. I go through it, so I have a pretty good idea. Then just talking to them as someone that was in like the worst kind of denial that you could be in, in regards to like my issues, you can kind of see it in other people.

I’ll warn them this is going to be a struggle unless you can accept that trauma that happened to you. The other point that you made in your last question about number one underlying causes, why SIBO happens? So the stress activates the sympathetic nervous system, which shuts down your stomach acid.

So the more of the mechanism of why is it the stomach acid, I think because the gut bacteria hate HCL. That’s another thing, I put people on hydrochloric acid supplements if we think they have low stomach acid. That’s a huge part of treating SIBO. If they haven’t done that, then that’s something that we can introduce.

I’ve had several people over the years where it was a course of antibiotics. They say,  “I took antibiotics and my gut has just been screwed ever since.” So that’s always a consideration. There are things like motility disorders. I would just think of more chronic constipation, chronic conditions that can affect your neurologic system like diabetes can slow down the motility and then you throw in stress, a bad diet, and it happens.

Dr. Ann-Marie Barter: And where can people get your book?

Dr. Peter Kozlowski: Yeah. So my book is called Unfunc Your Gut, funk with a C and it is available on Amazon, Barnes and Noble, your local bookstore, you can get it anywhere. I’m pretty sure Kindle. There’s a link on my website,
