Hi! Luca, Ryszard, and Dr. Ryan Martin here to answer all your questions about the microbiome, gut health, and Injoy (our startup)!

Injoy’s team is made up of a group of patients, doctors, and microbiome scientists who have spent years experiencing, treating, and researching gut health issues such as IBS, Crohn’s, Colitis, and more.

Gut health issues are unfortunately associated with a high degree of stigma where even talking about topics such as diarrhea, constipation, and stomas are still, for the most part, taboo. We intend to change this. Injoy, short for intestinal joy, represents the state of being we believe everyone deserves.

Inspired by our own struggles with gut health and those around us, we created Injoy to provide the best support to those with intestinal health issues. Check out our app, bathroom sensor, and microbiome test! -

We had a blast at our previous AMAs as Phyla (link below). So we're back to answer all your questions about probiotics, artificial sweeteners, AI, fecal matter transplants, Injoy, and m ore....ask us anything!

Why do you think gluten allergies have become so common among people?


cucciaman OP t1_itv505m wrote

Hi /u/PeanutSalsa,
Great question. There is definitely a mix of factors driving this increasing frequency of gluten allergies.

One theory is that the increase in the prevalence of gluten allergy is due to changes in the wheat that is grown today.

Another theory is that the increase in gluten allergies is due to the increased consumption of processed foods that contain gluten. For example, we see a much higher level of gluten allergy in Asian immigrants in the west. Before moving to the west, many people's diets consisted of much less gluten. It is therefore possible that the high level of gluten in the Standard American Diet is not compatible with many people's bodies.

Lastly, as with many diseases like cancer and autism, we have simply gotten better at diagnosing things and see them for what they are. So it may not be that there's a growing amount of the allergy, but that we are simply better at detecting it.

Thank you !

Speaking by anecdotes, I, seem to have issues with anything store bought/processed gluten. It's not even minor either it's pretty severe reactions. However, if I were to go and buy a bag of whole wheat flour, or even make my own flour from scratch with a blender and use that on recipes to make my own bread and other gluten products, I seem to have 0 issues.

I haven't put my finger on what it could be I check very carefully on labels now and try to make comparisons of products that flare me up although lately I've just eliminated most processed foods from my diet anyways since the recent findings that ultra processed foods is a leading cause of cancer.

Maybe it's the way they process the gluten these days or mixture of cheaper products/oils/ sugars/ flavors comparatively to about ten years ago. Whatever it is, it's in everything now. I have no choice but to avoid anything that isn't whole foods.


knowitallz t1_itx93l7 wrote

I saw something from Michael Pollan that was saying that if you add yeast to the wheat it naturally ferments / digests it so your body can more easily digest it.

I can eat organic bread that comes from a bakery with no gluten related digestive issues.

But if I eat a lot of processed stuff which has wheat flour or things like wonder bread then I have issues.

Usually those issues are constipation and what feels like high blood sugar

I actually haven’t tried making my own baked goods after realizing I’m gluten intolerant. I went from someone who ate a whole baguette throughout the day to not eating bread at all. I’m scared of risking it though. Not sure the pain is worth it anymore, I barely miss the actual bread. I just miss Chinese food.

Why does stomach inflammation happen in general? And for a person who experiences stomach inflammation from eating certain foods, why does it only happen when that person eats certain foods?


cucciaman OP t1_itvca8m wrote

>Why does stomach inflammation happen in general? And for a person who experiences stomach inflammation from eating certain foods, why does it only happen when that person eats certain foods?

Thanks for your question u/PeanutSalsa !

If you’re referring to gastritis, there are a few reasons this might arise.

In short, gastritis occurs when the balance between the mucosal lining of the stomach and the production of stomach acid begins to fall apart.

This can happen for several reasons such as infection by bacteria or viruses (Helicobacter pylori being a common one), Alcohol/painkiller consumption, and food poisoning, all the way to more autoimmune reasons, such as your immune system destroying the mucus producing cells. Even your lifestyle can cause acute inflammation if you are stressed or struggling with depression.

If you’re more curious about food triggers causing gastrointestinal symptoms…so are we!

As you said in your question, certain foods can trigger symptoms in some but not others. This is mainly due to the muscles within the gastrointestinal tract responding to hormones and other compounds that are released during digestion. The problem is, the gut’s response to foods will differ person to person. For some, eating foods high in dairy can cause diarrhea because they are unable to digest lactose (a type of sugar). For others, dairy might be fine, but they might experience severe GI distress after eating FODMAP foods, such as apples, because they are unable to break down and absorb the sugars that are present.

It’s important to note that triggers aren’t always dietary. Stress can cause GI discomfort as well. Similar to how you might feel like you need to go to the bathroom right before a big meeting.

Identifying food triggers is tricky and takes a lot of trial and error. It’s one of the features of our app we’re most proud of]! We want to be doing everything we can to help people understand their gut as quickly as possible so they can avoid any GI discomfort in the long run.

Hope this helps!

Hello! Thanks for the AMA, I have some questions for you guys,

. Can a healthy gut help in having clear skin? I've seen people who eat pretty unhealthy food but have clear skin while I who only ocassionaly eats unhealthy have acne (both hormonal and bacterial)

. How true is "dont drink milk after eating fish" and "no soft drinks after eating fruits". I'vr heard both from various people. Also are there more such combinations of food best not eaten together?

. Why would a clindamycin gel for your face cause diarrhoea?

. Is it ok to eat eggs every day?

. You know how sometimes a random part of your stomach or chest starts hurting? I guess most of those are harmless but what part of your stomach should you be concerned about if it randomly starts hurting.

Sorry if the questions are too trivial. Have a great day!


cucciaman OP t1_itw9eud wrote

Thanks for the questions! I can give you some more information on your first question regarding the gut microbiome and acne.

The gut microbiome is an important regulator of the body’s immune system. In people with an altered, or dysbiotic, gut microbiome the permeability of the intestinal wall is increased. The increased permeability leads to the release of inflammatory compounds signalling and increase in inflammation throughout the body. This can lead to an increased response to bacteria on the skin and the development of acne. In addition, there can be alterations in the skin microbiome due to transit of bacteria from the gut to the skin, with the altered skin microbiome leading to the development of acne.

As someone with a J-pouch, I am always looking for ways to improve my chances of not triggering a bout of pouchitis. Any recommendations on probiotics, supplements, etc that have proven success in maintaining bacterial symbiosis? Or foods to avoid?


cucciaman OP t1_itv6b2v wrote

Hi /u/draegs,

Great question. There is some evidence around the probiotic VSL no. 3, which consists of 8 different probiotic bacteria. Some small clinical trials have suggested this probiotic helps prevent pouchitis in adult patients, although further larger studies are needed to better assess the probiotics efficacy.

There is also evidence for other probiotics such as: the De Simone Formulation, Bifidobacterium longum, Clostridium butyricum MIYAIRI. However, keep in mind many of these studies are done on very low amounts of individuals. So it is best to wait for studies with larger amounts of people before we can say for sure that these probiotics prevent pouchitis.

Thank you for tuning in today.

I have terrible digestion, always have. I nowadays eat more soup, which helps, but the only thing that really seemed to cure it was a chinese restaurant soup, in a country I lived in years ago.

I couldn't tell you the recipe or ingredients, only that it involved stuff like sea weed and fungus. Are there some things I can eat that would help my presumably poor gut health? Appreciate this isn't medical advice, more lifestyle pointers!


cucciaman OP t1_itv79p4 wrote

Hi /u/Other_Exercise,

Sorry to hear about your situation, but the fact that you once had something that helps is hopeful!

To start, Asian restaurant soups will often use as base something called "miso" paste, which is a fermented food and can benefit your digestion. In addition, there is preliminary evidence that seaweed can be quite beneficial for the human microbiome.

Other ways to improve your gut microbiome health is again via adding fermented foods, such as kombucha, kefir, yogurt, kimchi, to your diet. Fermented foods contain live, beneficial bacteria that can lead to improvements in your gut microbiome. In addition, they contain a lot of compounds formed through the process of fermentation that are beneficial to you and the bacteria already in your gut.

I hope this helps you start towards better digestion, best of luck !

Thanks for the question! There have been many papers describing the oral microbiome and its connection with the gut microbiome. As you mentioned, both of these microbiomes are part of the larger digestive donut and it is not surprising that bacteria are able to travel from the oral to gut microbiomes. Similar to the gut microbiome, the oral microbiome has also been shown to be disrupted in patients with Crohn’s disease ( and Ulcerative Colitis ( Although it is still unclear whether these changes to the microbiome are causative or a result of the disease. With IBD primarily active in the lower GI tract, it is easy to see why a lot of research has focused on the gut microbiome and the bacterial activity in these regions. As we aim to better understand these diseases, it is important to consider the data in the context of the whole body and how the changes in the oral microbiome coincide with those changes we see in the gut microbiome. -RM

cucciaman OP t1_itvfghc wrote

Thanks for the question!

Several studies have found altered, or ‘dysbiotic’, gut microbiomes in patients with Myalgic encephalomyelitis (ME) or Chronic Fatigue Syndrome (CFS). A review of these papers found little agreement between them on what the specific changes to the gut microbiome were though. The link between ME/CFS and the gut microbiome is also evident by the improvement in self-reported symptoms after a short course of antibiotics in some patients (

Despite evidence that the gut microbiome is linked with ME/CFS, it is unclear how to improve the disease with microbiome targeted treatments. Some of the treatments being explored include specific probiotics, fecal microbiota transfer (FMT), and dietary interventions. Further research is needed to determine what microbiome targeted treatment can improve these patients microbiome and their symptoms though.

Once you become lactose intolerant, is there any way to restart the production of lactase?


cucciaman OP t1_itvi3d7 wrote

Great question u/IndyDude11 !

For the most part, lactose intolerance comes down to your genes and is not something that can be restarted, but instead supported. Believe it or not, less than half of the global population are able to produce enough lactase into adulthood to comfortably consume dairy regularly.

That being said, there have been some interesting publications that have looked into using probiotics to improve one’s ability to digest lactose and even the use of prebiotics to feed/sustain the lactose digesting bacteria. So there is potential for this being a solution in the future! But for now lactase pills are the best option for those with lactose intolerance.

Is there a link between trauma (especially childhood) and gut health? If so what factors are involved?


cucciaman OP t1_itvpt33 wrote

Thanks for the question!There's a saying that the gut is your second brain, and I think that's a fitting way to get into the topic of the link between the brain and gut. The brain-gut axis is a two-way highway of communication between these regions of our bodies. This relationship is bidirectional, meaning the activity and functioning of one can affect the other.

Early childhood trauma can lead to a large stress response in these individuals. The stress response can lead to changes in the gut microbiome through stress hormones and inflammation. The bidirectional communication between the gut and the brain means that these early life changes in the gut also affect the brain at a time period critical to its development. In addition, there is some evidence that these alterations can lead to increased risk of developing stress related disorders later in life.

Is there anything within the gut that can exasperate fatigue and what can I do to help it give me more energy?

In case you're not already aware, there is a SIBO subreddit support group r/sibo I believe. Definitely keep a food journal. It takes a while to sort things out but I've noticed there's a link with certain foods and feeling worse. Good luck with things. Oh and if you have insurance issues with them covering Rifaximin as often as you need it (when I first started I needed to be on it for 3 weeks every 2 months for about a year but my insurance only covered twice a year), the drug manufacturer has a program that they'll send you prescriptions direct from them for free. It's a lot of paperwork unfortunately but worth it vs paying out of pocket.


cozyessi t1_iug2wu3 wrote

That’s super helpful to know! Thank you!!


cucciaman OP t1_itvaz4e wrote

Hey /u/cozyessi,

I'm happy to hear that the antibiotics helped. SIBO is tricky and still very poorly understood. I'm going to list some recommendations for maintaining a healthy microbiome below:

FoodThe low FODMAP diet has been shown to be effective at helping prevent SIBO recurrence.In general, you can improve your gut microbiome health by adding fermented foods, such as kombucha, kefir, yogurt, kimchi, to your diet. Fermented foods contain live, beneficial bacteria that can lead to improvements in your gut microbiome. In addition, they contain a lot of compounds formed through the process of fermentation that are beneficial to you and the bacteria already in your gut.

However, as a SIBO patient, some of these may worsen your symptoms. The response to diet is highly personalized and I would recommend you try some of these things to see what improves.Lastly, lifestyle aspects have been associated with features of a healthy gut microbiome. Specifically, some studies have identified links between good sleep quality and exercise with positive improvements in the gut microbiome.

It also sounds like fatigue is something that is bothering you. Fatigue can be caused by many different things, so I will give you an answer in the context of the microbiome. Often, when our digestive system is out of balance, we can develop inflammation in our gut, especially in the context of SIBO. This inflammation has been linked with brain fog and fatigue-like symptoms. I would see if there's a link between your digestive symptoms and your fatigue as a first step. As you address your digestive symptoms, your fatigue could improve in parallel.

Thank you !

Kombucha falls into the category of fermented foods which are foods or beverages produced with live cultures of microbes. Fermented foods contain live, beneficial bacteria that can lead to improvements in your gut microbiome. In addition, they contain a lot of compounds formed through the process of fermentation that are beneficial to you and the bacteria already in your gut (
A recent study looked more closely how fermented foods alter a person’s gut microbiome. In this study, they showed that fermented foods increased the diversity of bacteria found in the gut. Diversity is a common measure used to characterize the gut microbiome, and generally the greater the diversity the healthier and more stable the person’s gut microbiome. Interestingly, few of these bacteria were actually from the fermented foods in the people’s diets. The study suggested it was because of the other components of the fermented foods, such as compounds produced during fermentation, that provide a more hospitable environment to new bacteria (

what causes acid reflux and how can I stop it?


cucciaman OP t1_itvf8p9 wrote

Great question u/emiredlouis !

Acid reflux, commonly referred to as heartburn, happens when stomach acid makes its way into the esophagus.

This can be triggered by many different things, such as acidic/spicy/fatty foods, certain medications (OTC painkillers), stress and anxiety and more.

So in short, try and take note of the foods you’re eating prior to feeling symptoms of heartburn, try to avoid them, and see if this reduces your discomfort. Just keep in mind that foods are not the only possible culprits.

For most people getting a little heartburn after a large meal is not an issue. It’s when this becomes a chronic issue that you should consider consulting a physician.

I’ll include a great article here from Ceders-Sinai with background on acid reflux and some of the potential triggers that are out there.

Hope this helps!

Sorry to hear you had such a rough time.

H. Pylori is extremely common with the majority of the world’s population having some in their bodies. In most cases symptoms are rare, but in others ulcers and inflammation can be found.

When it comes to prevention (I had to look this up) there doesn’t seem to be much outside of general hygiene to avoid a recurrent infection. I’ll include some links below from the Mayo and Cleveland Clinics, but the general gist is to make sure you’re using and consuming clean water and washing your hands thoroughly before eating.

I know this probably isn’t the answer you were looking for, but recurring infections tend to be rare; mainly occurring in developing countries and shortly after being ‘cured’ due to incomplete clearance. Due to the fact that you mentioned it has been years since your infection it seems you’re in the clear :)

Thanks for your question u/MasterPainting5098 !

I get asked all the time about how antibiotics impact the microbiome. Long story short, the science is still evolving on this subject and there’s no magic bullet solution. While there’s lots of discussion going around about using probiotics, fecal microbiota transplants, phage therapy, and other interventions, there’s not enough research or accessibility of these options for us to confidently support them at this time.

That being said, there are a number of things that are known to help healthy bacteria grow, thrive, and populate the gut.

-Try the Mediterranean diet. The variety of foods rich in fibers, vitamins, minerals, omega 3 fatty acids, and more nutrients feed your gut bacteria, helping them survive and produce byproducts needed for healthy digestion.

-Incorporate fermented foods and beverages, such as sauerkraut and kefir, into your diet. Fermented products contain beneficial bacterial species that can help restore the gut microbiota.

-Reduce your sugar and artificial sweetener consumption, as these products can increase inflammation or lead to further imbalance in the gut microbiome.

FYI I took some of these tips from a blog post we wrote where we combine research from ~10 peer-reviewed publications on this topic. Hope you find it useful!

cucciaman OP t1_itvlmkb wrote

Thanks for the question!

One potential explanation is that gas is moving through your intestines along with your stool, but there is more gas being produced than can escape at a given time. Intestinal gas is produced by the fermentation occurring when the bacteria in your gut digest the foods you are giving them. Several different types of food have been associated with increased gas production, including beans, peas, lentils, and cruciferous vegetables. One common characteristic of these foods is the large amount of soluble fiber, which is digested by bacteria in your gut and leads to gas production.

cucciaman OP t1_itvm2j3 wrote

Thanks for your question u/CatKitKatCat!

How is it possible that a person can have totally normal colonoscopy results even if they have such severe gut issues?

This is a very frustrating issue that we get asked about all the time.

A colonoscopy is mainly focused on examining the colon for growths (such as polyps), inflammation and other physical abnormalities such as sores. As a result, colonoscopies are great when it comes to detecting things such as colon cancer and in most cases Crohn’s and Colitis (visible inflammation), but are of little value when it comes to something such as IBS. Except when ruling out other conditions of course. In the case of IBS, which is not a single condition but instead a combination of symptoms caused by gastrointestinal dysfunction, it is highly unlikely anything indicating its presence would be seen. This is an issue that is also experienced in the case of celiac disease and some drug side effects.

If a person has ‘absorption issues’ with low vitamin/mineral levels, how does the gut influence that?

Another great question!

Malabsorption of vitamins and minerals is a big concern for those with conditions such as IBD. In the case of Crohn’s, up to 75% of patients might be malnourished. There are a few reasons for this: their intestines are too inflamed to properly absorb nutrients, their microbiome has been impacted so they are unable to produce the necessary vitamins ‘themselves’, and they might simply be eating less due to the medications they’re taking or the symptoms they’re experiencing.

Different vitamins and minerals are also absorbed at different points along the digestive tract. So if a patient’s Crohn’s is primarily localized to their ileum they would have issues absorbing vitamin B12 since this is the only place in the body it can be absorbed.

If you’re curious to learn more, we wrote a blog post to break down how the different areas of the gut are responsible for absorbing different vitamins and minerals! Feel free to check it out!

cucciaman OP t1_itvptn9 wrote

Hey u/Masek_Kiel , thanks for your question!

First and foremost if you’re experiencing chronic digestive problems you should see a medical professional such as your primary care provider or a gastroenterologist.

There are a handful of tests out there that people with digestive problems can take, namely microbiome/stool tests, food intolerance tests, and general blood tests.

Full transparency our startup, Injoy, has a microbiome test we are extremely proud of. We are a group of patients, doctors, and researchers so validation is core to our offering (we have peer reviewed publications and have begun a few clinical studies). Our microbiome test is unique to others because we have you take 3 samples instead of 1 so we can see how your microbiome is changing over time in comparison to your diet and lifestyle (tracked in our app). We also sequence our samples so we can see all the bacteria present as opposed to a few preselected ones which allows us to provide a more personalized report. Here’s a link to one of our example reports.

Other stool tests look for the presence of inflammatory proteins, blood, or parasites.

At-home food intolerance tests are also very common, but commonly leave much to be desired. Mainly due to the fact that they are most applicable to food allergies which mount an IgE response as opposed to food intolerances and sensitivities which do not. In other words, great for detecting a peanut allergy, but less useful for telling you to avoid tomatoes.

General blood panels are the standard type of blood test you do at the doctor’s office and are a great way to understand a wide swath of things such as your hormone levels and lipid levels. This is helpful when it comes to understanding your liver health, cancer risk, and more in addition to how your body is functioning overall.\

Why is it that some people have a hard time digesting heavy foods?


cucciaman OP t1_itvw6nh wrote

Great question u/PeanutSalsa !

In short, heavy foods can include many hidden ingredients that can make us feel uncomfortable after eating.

For example, many places you might order takeout from probably use cheap oils to cook their food. Commonly soybean oil, sesame oil, and canola oil. These oils are filled with linoleic acid — a polyunsaturated omega-6 fatty acid  — which can cause inflammation in the body.

Additionally, heavy foods normally mean fatty foods. Fat in general requires several steps before it can be broken down in the digestive tract, such as enzymes in saliva, acid in the stomach, and bile. Additionally, different types of fat can impact the speed of contractions occurring along the digestive tract leading to both diarrhea and constipation depending on whether or not contractions are sped up (diarrhea) or slowed down (constipation, bloating…).

Hope this helps!

A person can develop a dysbiotic microbiome from an unhealthy diet, the development of some diseases, or high amounts of stress, to name a few. One way an unhealthy gut microbiome can lead to the development of headaches and migraines is through increased inflammation. The unhealthy gut microbiome can lead to an increased production of pro-inflammatory compounds in the gut and an increased permeability of the gut lining. The compounds are then able to affect other parts of the body, such as the brain. Many of the pro-inflammatory compounds released have also been implicated in the development of migraines.

The mind and the gut are more closely linked than many people realize. It’s the reason why our mouth waters and our stomach gurgles when we see yummy food or why we might feel the need to throw up when we get nervous or scared.

With this in mind it’s not hard to imagine that fermented foods could boost your sleep. One theory is that inflammation in the body can worsen sleep quality, which can in turn drive further inflammation. A recent article showed that regular consumption of multiple portions of fermented foods daily could substantially reduce inflammation in the body.

Perhaps the anti-inflammatory effects of the fermented foods you're having could be positively impacting your sleep.

My understanding is that most probiotic supplements in stores and online are generally useless and a waste of money. Can you advise on this or give me a recommendation of what I can do to improve my gut health? Thankyou

Do smellier farts mean a healthier gut/better digestion?

Hey guys, what are the biggest myths/misinformation about the microbiome?

Is the microbiome responsible for histamine intolerance?

Can you talk a little about sugar and the gut microbiome? I’m trying to cut back but it’s extremely hard to limit sugar because of habit, and because it’s in everything. I’m also often confused about whether or not to eat fruit, rice, or pasta, or drink kombucha. What happens to your microbiome when you cut back on sugar?

Can you explain how I reversed my dysbiosis, biliary dyskinesia, and myriad of food sensitivities through conscious intervention only?

I’d love to know the science on this!

More info: I suffered with gallbladder issues and IBS symptoms for 4 years, to only reverse it in a couple months by creating a lifestyle where gut problems couldn’t exist (physically, emotionally and thoughts)

Chiming in to say I’m curious to know what you did, if you have the time to give any input :)

Does colonoscopy preparation/purging (not sure of the proper term) or the colonoscopy itself have adverse effects on the microbiome?

Does too much acid cause burping?

I’ve heard a lot about how low stomach acid can cause indigestion, which in turn causes gas build-up in the stomach.

However, lately I’ve been having A LOT of gas (burping constantly, even before I eat anything). When I tried to take HCL Betaine supplements, the burping got worse instead of better. Is it possible the burping / gas could be caused by too much acid? And that I made it worse by adding more acid to it (with the HCL supplement)?

I have always had what I called a sensitive stomach. I had to be really careful with oily or fried foods, even red meat too. It’s gotten much worse and csn hardly tolerate it now. I’m down for the count after. My stomach is wrecked and I just curl up in a fetal position if I’m able. I always feel extreme nausea, headache, & a bad left over taste in my mouth. I go try tums or pepto bismol but they don’t really help. Friends know but sometimes they don’t realize how careful I have to be with oil. I already avoid these foods but what else could I be doing to help?

What's your thoughts on taking Rifaximin for IBS-D long-term? Also I drink a lot of milk around 32 ounces a day (the half sugar, double protein, lactose-free) kind. Is this bad for gastrointestinal health even though it's lactose-free?

There's microplastic in everything we consume from fish to processed cheese. How will it effect us and the animals on this planet? Can we die from overconsumption of microplastics and is there anyway to avoid this?

Sugar or artificial sweetener?

If I'm not primarily concerned with putting on weight, should I drink a gun and tonic with sugar or a diet version? I do realise I should drink neither, I'm just curious about which is considered worse?

Have you done any research on the effectiveness of cannabinoids to help or harm the gut? More specifically CBG and CBD?

Are there microbiomes in other parts of your body? Say your prostate or your liver? Are they sterile or what?
