Inside your gut lies an unexpected world, teeming with microorganisms. This tiny universe, invisible to our eyes, plays an immense role in our health. In this article, we explain what the microbiota really is and why it deserves your full attention.
What is the microbiota?
Imagine your body as a vast galaxy housing billions of microorganisms: bacteria, viruses, fungi… These tiny inhabitants, invisible to the naked eye, form well-organized communities called microbiota, which are found in various parts of the body: nose, mouth, genital organs, skin, but most importantly… in our gut! If all of them were gathered together and weighed, they could total up to 2 kg (4.4 pounds)1!
In this article, we will focus on the gut microbiota, a true cornerstone of our health. Did you know that 70 to 80% of the bacteria in our body live in the gut? They include hundreds of different species and play such essential roles2.
Bacteria: friend or foe?
The word “bacteria” often has a bad reputation. However, not all bacteria are “bad”! Our body also hosts many beneficial bacteria that support our health. Each one has its own specificity, and the more diverse they are, the better they collaborate to protect us and maintain our body’s balance.
Why is balance so important?
A healthy microbiota is characterized by a wide variety and abundance of good bacteria. This balance is crucial to prevent ‘dysbiosis,’ an imbalance that occurs when good bacteria are depleted, harmful bacteria proliferate, or microbial diversity decreases. An imbalanced microbiota can have significant consequences on our health.
Our microbiota is threatened by our lifestyle
Unfortunately, our modern lifestyle disrupts the balance of our microbiota, making it more prone to dysbiosis. Just like the planet’s biodiversity is at risk, the diversity of our gut bacteria is also under threat. The more industrialized a society is, the less diverse its microbiota tends to be.
The main contributing factors?
- Highly processed foods that are low in fiber but packed with sugars and all kinds of additives
- Excessive hygiene, limiting natural exposure to microorganisms
- Frequent and sometimes excessive use of antibiotics, which wipe out both harmful and beneficial bacteria3.
The consequences are far from minor. When the diversity of our microbiota decreases or becomes imbalanced, it can trigger various digestive issues (constipation, diarrhea, abdominal pain, bloating) and, over time, raise the risk of serious chronic conditions like diabetes, obesity, autoimmune diseases, cardiovascular problems, and even certain neuropsychiatric disorders4-8.
How is the microbiota formed?
It all begins at birth!
The story of our bacteria starts as soon as we enter the world. Before birth, a baby’s digestive tract is sterile, meaning it contains no microorganisms. During vaginal delivery, as the baby passes through the birth canal, they acquire their first “batch” of bacteria, primarily from the mother’s vaginal and fecal microbiota. In the case of a cesarean section, the baby’s microbiota is different: it is more colonized by bacteria from the hospital environment, the mother’s skin, and later from the father’s skin during skin-to-skin contact. This first exposure to bacteria is crucial because the first arrivals have the advantage over others: they settle in the best spots in the intestine. In other words, it’s a “first come, first served” rule 😉10.
Until the age of 3 to 5 years, the microbiota continues to evolve and diversify, influenced by various factors such as food intake, hygiene, medications, environment, and even genetics. Among these factors, breastfeeding, followed by the introduction of solid foods, plays a key role. Exposure to the environment—such as where we live, whether in the countryside or the city, or even contact with animals—also contributes to enriching and shaping the microbiota, which ultimately becomes unique to each individual11.
The key role of diet and lifestyle
Just like fingerprints, the gut microbiota is unique to every individual. However, it is not permanent: less than 10% of our microbiota is influenced by our genetics, while the rest can evolve depending on external factors. It’s a dynamic ecosystem.
A recent study reveals a surprising fact: people living in the same house, even if they’re not related, share a more similar microbiota than family members living apart12. This demonstrates that our diet and lifestyle have more influence than our genetic heritage! And that’s excellent news, as it means we have the power to directly impact our microbiota. Within just 24 hours, changes in dietary habits can begin to alter its composition13.
The superpowers of the microbiota
Although invisible to our eyes, the tiny organisms inhabiting our gut possess superpowers far beyond their size. Let’s explore the main benefits of these microscopic allies!
Production of really useful molecules
Our gut bacteria can produce essential vitamins for the body, such as B vitamins, which boost energy, and vitamin K, which is crucial for wound healing14.
The microbiota can also create remarkable small molecules called short-chain fatty acids (SCFAs) from the fiber of our diet. These SCFAs are true multitasking molecules15:
- They make the intestine slightly acidic, which slows the growth of harmful bacteria.
- They provide energy to intestinal cells, helping them regenerate quickly.
- They strengthen the intestinal lining, our protective barrier that prevents bacteria, toxins, and allergens from entering the bloodstream—a true defensive wall!
A guardian of our immune system
The gut microbiota acts as a natural shield, protecting our body through several mechanisms16:
- Physical barrier: The large number of beneficial bacteria forms a protective layer. Imagine an army of good bacteria lined up like a strong wall to defend our body—that’s our microbiota watching over us!
- Competition: When beneficial bacteria are abundant, they deprive harmful bacteria of nutrients, limiting their growth.
- Production of natural antibiotics: Our good bacteria produce “natural antibiotics” that inhibit the growth of harmful bacteria.
But that’s not all! The microbiota also regulates our immune system, helping our white blood cells identify real threats, like certain viruses and harmful bacteria. This allows the immune system to focus its defenses on actual intruders, avoiding attacks on good bacteria or, worse, our own cells17!
A regulator of weight and metabolism
The gut microbiota influences how we store fat and gain weight. This might partly explain why some people are more susceptible to weight gain than others, even with similar eating habits18,19.
Moreover, the microbiota affects our appetite and satiety. Depending on its composition, it can even influence cravings for fatty or sugary foods!
A key player in mental health
The microbiota plays a crucial role in communication between the gut and the brain, notably through the production of neurotransmitters (chemical messengers)20,21. Did you know that 95% of serotonin, often called the “happiness hormone,” is produced in the gut thanks to the microbiota?
The gut microbiota and the brain maintain a constant dialogue, often referred to as the gut-brain axis. This connection is tangible: who hasn’t experienced a stomachache before a stressful event? But this dialogue goes far beyond fleeting emotions—it influences our mood, stress levels, and may even play a role in complex disorders such as anxiety or depression22,23. Maintaining a balanced microbiota is therefore essential for our mental health.
Star foods for a healthy microbiota
Taking care of your microbiota starts on your plate. This precious ecosystem thrives on whole foods and fermented foods. Here are the must-haves to include in your daily diet!
 | Fiber |
Dietary fiber is essential for your gut’s microbiota health. Yet, most of us consume far too little! In France, 89% of adults fail to meet the 25 g/day recommended by the WHO, and in the United States, this figure rises to 95%24-26. However, getting enough fiber helps reduce the risk of strokes and diabetes27.
Why is fiber so important? Since fiber isn’t digested by the stomach or small intestine, it makes its way to the colon intact, where it becomes a favorite food for gut bacteria. These bacteria ferment the fiber, producing short-chain fatty acids (SCFAs) that offer incredible health benefits.
Here are some foods to prioritize28:
| 🥕 Vegetables | Garlic, artichokes, asparagus, beetroot, broccoli, carrots, chestnuts, endive, cabbage, fennel, green peas, corn, onions, parsnips, leeks, sunchokes |
| 🌿 Legumes | Beans, lentils, peas, fava beans, chickpeas |
| 🍎 Fruits | Avocado, bananas (not too ripe), dates, figs, kiwi, apples, nectarines, peaches, pears, prunes |
| 🌰 Nuts | Almonds, peanuts, walnuts, hazelnuts, pistachios |
| 🌻 Seeds | Chia, flaxseed, sunflower seeds, pumpkin seeds, sesame seeds |
| 🌾 Grains and starchy foods | Oats, whole wheat, millet, barley, cooled potatoes, quinoa, brown rice, rye, buckwheat |
Tips to boost fiber intake:
- Opt for whole fruits and vegetables. You can also eat the skin, as it often contains a lot of fiber—just make sure to opt for organic produce, since the skin can also concentrate pesticides.
- Limit fruit juices, which are low in fiber and normally high in sugar.
- Choose high-fiber grains like brown rice, buckwheat, oats, or quinoa, as they contain more fiber. Ideally, go for organic options, since the fiber is mostly in the outer layer of the grain, which also tends to concentrate pesticides.
- Add legumes to your meals at least twice a week29: chickpeas, beans, lentils, fava beans – To make them easier to digest, soak them in water overnight before cooking, then rinse them 2 to 3 times.
- Use less refined flours and opt for whole grain or ancient varieties like spelt or rye.
- Consume cold starches (like rice or potato salads). When cooled, they contain more resistant starch, a type of fiber that nourishes good gut bacteria30.
- Sprinkle seeds on your meals: on salads, yogurt, or baked goods. Remember to soak flax and chia seeds in liquid before consuming them, as they are great for supporting transit!
 | Polyphenols |
Polyphenols are natural compounds plants produce to defend themselves against external stressors like insects, mold, or UV rays. And what protects plants can also protect… your microbiota! These compounds stimulate the good bacteria in your gut and boost microbiota diversity31.
The richest food in polyphenols include red fruits (blackcurrants, blueberries, raspberries), artichokes, coffee, dark chocolate (at least 70% of cocoa), black and green tea, and spices like turmeric, cloves, and anise32,33. By eating these foods regularly, you give your microbiota a real boost!
 | Organic Products |
It’s better to choose organic fruits and vegetables, as they contain on average 20 to 70% more polyphenols than conventional ones34. Eating organic food also helps you avoid exposure to chemical pesticides, which can weaken or kill certain bacteria in the microbiota. A double benefit!
 | Fermented Foods |
Fermented foods, such as yogurt, certain cheeses (especially those made with raw milk)35, kombucha, kefir, miso, tempeh, and lacto-fermented vegetables (like kimchi and sauerkraut), are a true treasure for your microbiota. These foods are packed with live beneficial bacteria that support the diversity and balance of the microbiota. They can be considered natural probiotics, contributing to both digestive and overall health36-38.
To fully benefit from their effects, it’s essential to consume these foods raw or unpasteurized, as heat destroys the live bacteria.
The enemies of a healthy microbiota
Now that we know why and how to take care of our gut microbiota, let’s review its worst enemies.
 | Antibiotics |
Antibiotics are designed to eliminate bacteria responsible for infections, but their mode of action is non-selective: they also destroy many beneficial bacteria of the microbiota. Like a bomb, the explosion will eliminate harmful bacteria but also causes collateral damage by killing “friendly” bacteria.
This phenomenon can have significant consequences, especially for children under three years old, whose microbiota is still developing. At this age, disrupting this delicate ecosystem can increase the risk of long-term health problems, such as asthma, food allergies39, diabetes, obesity40, and chronic inflammatory bowel disease41. In cancer patients, studies suggest that antibiotics may even reduce the effectiveness of chemotherapy and immunotherapy42.
While antibiotics are indispensable in certain situations, particularly for bacterial infections, it’s crucial to use them only when necessary, follow your doctor’s advice, and avoid self-medication.
 | Ultra-processed foods |
Packed with added sugars, saturated fats, and various additives, ultra-processed industrial foods can disrupt the microbiota.
Research indicates that certain food additives, such as emulsifiers, sweeteners, and colorings, can deplete and destabilize the gut microbiota while weakening the intestinal barrier. When this protective barrier becomes more permeable, harmful substances can enter the body, triggering a “silent” yet persistent inflammation.
Over time, this chronic inflammation can weaken the body and increase the risk of developing chronic conditions, such as allergies, certain autoimmune diseases (like Crohn’s disease), or even some cancers43-49.
 | Lack of physical activity |
Spending too much time inactive can harm the microbiota, reducing its diversity and weakening the intestinal barrier, which allows undesirable substances to pass through50.
On the other hand, physical activity enhances microbial richness and diversity, boosting the production of SCFAs (short-chain fatty acids)—valuable multitasking molecules51,52. It’s a win-win relationship: physical activity stimulates the microbiota, which in turn produces substances that increase our energy and physical performance, encouraging us to move even more53,54.
No need to run a marathon—the key is to stay active every day with simple, regular activities!
 | Chronic stress |
Prolonged stress disrupts the microbiota by increasing the production of cortisol, a hormone that promotes inflammation and destabilizes the gut. Additionally, stress often intensifies cravings for sugary or fatty foods, which feed “bad” bacteria and exacerbate inflammation. This can create a vicious cycle: the more we are stressed, the more we tend to adopt poor eating habits, and the more inflammation increases, further aggravating the situation55.
To break this cycle, it’s essential to take time each day to relax—whether through meditation, a walk in nature, or simply by a few minutes of deep breathing.
 | Excessive hygiene |
In the pursuit of disinfecting and sterilizing everything, we risk weakening our microbiota and especially for children, whose microbiota and immune systems are still in development. Overprotecting them from environmental microbes restricts their microbiota and their immune system from learning to differentiate between beneficial and harmful bacteria, leaving them more vulnerable later on.
A little bit of contact with germs is actually beneficial, as it helps the body learn how to make the difference between bad and good bacteria. Studies show that in populations with less strict hygiene practices, microbiota diversity tends to be higher—a key factor for better overall health56 !
Of course, maintaining hygiene is important, but it’s important not to become overly obsessive about it.
 | Not enough sleep |
A lack of sleep or an irregular sleep schedule can disrupt the balance of our microbiota. Just as our bodies are designed to be active during the day and rest at night, the microbiota is the same. Our microbiota loves regularity!
Even a slight disruption to this rhythm—such as staying up too late or getting too little sleep—can lead to an imbalance in the microbiota. Over time, this imbalance may contribute to the development of various chronic diseases57.
In summary: 10 keys to a healthy microbiota
Now that you understand the importance of the microbiota for our health, here are 10 essential tips to remember:
 | Let children explore their environment Encourage them to spend time outdoors, interacting with nature and animals. A little bit of "dirt" helps their bodies prepare better for real threats. |
| Limit antibiotics Use them only with a doctor’s prescription and avoid their use as much as possible in young children with fragile microbiota. |
 | Diversify your diet Eat a wide variety of foods rich in fiber and polyphenols (fruits, vegetables, legumes), and include fermented foods. |
 | Opt for less processed foods as possible Avoid ultra-processed foods and opt for homemade meals made with raw, organic, and seasonal ingredients. |
 | Include at least one different fruit or vegetable in every meal Variety is just as important as quantity! |
 | Choose whole grains over refined ones They are richer in fiber and better for your microbiota. |
 | Incorporate legumes into your meals Add them to your menus at least twice a week. |
 | Stay active! Even 10-15 minutes several times a day can make a difference. |
 | Take care of your sleep Go to bed at regular times, aim for 7 to 9 hours of sleep per night, and limit screen use in the evening, stopping at least an hour before bedtime. |
 | Prioritize mental well-being If you work in front of a screen, take 5-minute breaks every hour. Dedicate at least 10 minutes a day to meditation or deep breathing exercises. |

I really enjoy and benefit from the Yuka app.
Thank you for all you do!!

Very informative article. Thank you!
Excellent article! I truly believe that the chemicals, mostly preservatives, used in food is a significant contributor to our obesity, heart disease, and mental health in US. Also, believe we just need to slow down. Way too much traveling around for no reason. What happen to people just chilling at there homes. It appears to me everyone is busy doing nothing and stressed about nothing!

My favourite app of all👌
Very well written! In terms many can understand and incorporate. It helped me better understand the context, thought process, science, and how my body processes in terms and simplicity that help me communicate to my family. Thank you!
I truly appreciate your app and use it consistently, which has helped my family eat healthier foods. It has also helped me realize just how marketing truly impacts selling products – I’ve always known it; however, the more I read labels, the more I realize the true impact of marketing.
Great resource, thank you. This article was a family share especially as we are now armed with the Yuka app and can make better grocery decisions.
Great info. I use your app while shopping.
I’ve read and used info from the book “Eat Right for Your Blood Type” and definitely found that a Blood type A (vegetarian base) requires much different foods than a Blood type O (carnivorous base). Myself and my husband, although completely opposite can still bring together the best benefits for both is essential to achieve energy, stamina, and help to deal with stress in a busy lifestyle. Your company could improve every persons life with this basic info being added to achieve an even better eating result by feeding the michrobiota with foods best for a persons blood type. I prepared foods best for my type A blood type and it affected my macho blood type O husband by become weak and fatigued compared to my type A when eating proper foods had built my energy and stamina to a level that I could out walk and out work my husband in the Yellowstone backcountry during a short trip to the mountains and hiking. I saw first hand how dependent my husbands health was on meats and his type of foods.

This is very informative but please tell me how I can incorporate this type of foods into a Carnivore diet? is there a way to do this? or no, your thoughts please.
Organic grass feed meat that is not over cooked but of course cooked.
You have a wonderful web site. My wife and I learned about yuka in December. The man who told us about it said we would throw half of the food items in out house before we went to bed. What’s even better is we use yuka when we food shop.
Great article ore people in the U.S. need to read it then we might have less fat people.

Perfect timing cuz my gut is going thru diagnostics as i suspect there are some undesirable critters (parasites) in my gut picked up in the jungles of central america ( or what ever its called now 🤡). This will help keep my second brain in control if the other one nods off again
Thank you

This article is very informative. Reviewing the best way to keep gut bacteria healthy helps me remember what to focus on. Thank you for sending this article.
Enjoyed this article, as there is always room for improvement!! Knowledge is Power, TY 😊
Great article!
Thanks for the info and thanks for this great app. My wife and I don’t go shopping without it. We call out products that we use to eat and tell the manufacturer that we not buy their product any more because of the additives in the product. I think if we all use this app. we can make a difference.
Very informative article. I learned a few things didn’t know added information to the things I did. Thank you
Great article.
Great article!!
This is a great article! I have studied the gut microbes for years online and have found programs to help balance yeast. I am trying to find a way to fight the use of preventative antibiotics. In the last year I have had a shoulder replacement, 2 implants and a tooth extracted all requiring 10 days of preventative antibiotics (no infection at all). Also, the surgeon orders anyone that has an artificial joint to take 4 antibiotics before every dental appointment for the rest of our lives. I’ve had to go to the dentist at least 10 times in the last year. This blanket protocol is destroying my digestive system. I’ve fought digestive issues in the past and I’m now having all the symptoms you talked about here. My dentists ask me if I’ve taken the antibiotics and won’t work on me if I haven’t. The ADA has an article online about this abuse and they claim that it doesn’t prevent infection and is unethical because of the development of drug resistant bacteria. Thanks again, I will try to get my surgeon a copy of this article.
Wonderful article! Very interesting about how the first three years have such an effect. My husband always had stomach porblems and now we have beens everyday. His stomach problems are gone.
Great article. Well written.
Both my wife and I use Yuka but only she got your email. Please ensure I get them too, my name and email are below
Good article. I love your app. In times like this it would be useful for it to inform the buyer where the product is produced. (Ingredients and manufactured). I have learned that “produced” means that 98% of the product is from (Name of Country) and “made in” means only 51% of product is from (that country listed). I’m hoping the next update will include these facts if possible.
Thank you, this is great information not only for myself but my German Shepherd who struggles with allergies and inflammation. He gets fresh food now but I really need to learn these things for my own eating habits as I am really trying to eat healthier (using your app all the time!) Thank you!
A good review of the facts. A reminder never hurts. Good info. Thank you.
Great article, very informative! Thank you!
Great info. Thank you!
Thank you! Some good and logical and easy to follow suggestions.., I need to work on a few of them.

Nicely comprehensive article, thank you!
Lectins cause leakygut in a number of the foodsbyou recommend. Liik up Dr. S. Gundry. .. ..

The Yuka app as changed my life for the better! I recently shared this app with a health class that I am taking and now everyone in the class is using Yuka! I love the informative articles as well. Thank you for making a positive difference in my life and countless other lives also!
Thank you so much for writing this article! My 2025 goal is to lessen chemicals in my food and makeup! Thanks to the Yuka app!!
Fantastic article. Very informative. Thank you
This was a great article, Thanks!
I was diagnosed with IBS-C & D a year ago. I have been in the ER several times for the pain. I have tried everything possible to help this with no luck! I am currently trying the FODMAP diet but I don’t feel as if I am getting the proper nutrition. I use your app at the store all the time! For some reason I am only getting a few days a week pain free. I loved this article but was curious if you have any literature on my condition? Thank you in advance….
I love Yuka. I use it before I buy anything. Very helpful. I follow everything in your article. I am a healthy 84 year young and active female. I take no medications.
So much super good information. I love reading about resistant starch… something I only found out about recently…ALL of the article makes so much sense…
Very informative article.
Thanks
You are changing our eating habits, one product scan at a time!
Wonderful information and important reminders! Thank you for sharing!!!
Great article, I will try to include more fiber into my diet!
Very informative! Do you recommend probiotics, prebiotics?
Probiotics and Prebiotics have different functions and are both needed for a healthy gut. Prebiotics are a food source for probiotics and probiotics are those living organisms such as bacteria and yeast. So you need prebiotics such as whole grains, fruits and veggies to feed the probiotics organisms in the yogurt, kefir, and other fermented foods. All in all, you need both!
Thank you for such great and relevant information.
Very helpful summary! Thanks!
Thank you. I appreciate the information.
It is a wonderful article. I am looking back and remembering that when my daughter was a baby, she had to have antibiotics for ear infections. I am sad to read that this disrupts a child’s developing microbiota and now realize why she has IBD along with Celiac.
Awesome and very helpful. I’m proud for this community and Yuca developers. Keep going to this amazing job.
Thank you! Wonderful and helpful article!!
This was an excellent article!
Your YUKA app is fantastic and these informative articles are timely and important! Thank you:)
Thank you so much- very considerate and easy to follow..
I recently learned that acid blocking medications, over the counter as well as prescription, can affect the gut biome as well. I was prescribed a high dose for a short period of time following a heart ablation and began experiencing gastrointestinal issues while taking them. Once I figured out the source of my issues I am focusing on improving my gut health by diet and pre and probiotics as needed. This article is a great resource.
Wonderful article!
Very informative, cuz I’m trying to eat better and I love your app!
Thank you! I had to take antibiotics for a bad bladder infection. Forgot to take yogurt with it and went through two weeks of stomach pains.
I would love to see a further article on probiotics that you find do the best job. Thank you again… I’m very happy to have some good knowledge on the subject.
Thank you,very helpful info.
Great article, so nice to read through and not have a product to buy at the end. Good wholesome information, thank you.
We don’t purchase anything without checking it with Yuka App
