Building a healthy gut flora: Your practical guide to feeling better in your gut

Do you often feel low on energy, constantly bloated, or repeatedly struggle with digestive problems? These aren't coincidences, but clear signals from your body that very often point to an imbalance in the gut. To specifically build a healthy gut flora, you need more than just eating a few yogurts. It requires a combination of smart, gut-friendly nutrition, clever stress management, and above all, knowledge about your very own microbiome.

The first step toward your gut health

Maybe you know the feeling: You try hard to eat healthily, but you still don't feel truly fit. Blemished skin, mood swings, or that constant fatigue may also have their roots in your gut. Your gut is so much more than just a digestive organ—it is the command center for your overall well-being.

A healthy gut flora, also called the microbiome, is a gigantic ecosystem made up of trillions of microorganisms. These little helpers are absolutely essential to you:

• They're your personal bodyguards: An incredible 70% of your immune cells are located in the gut. A diverse gut flora trains your immune defenses and helps you fight off pathogens.
• They influence your mood: Through the so-called gut-brain axis, your gut is constantly chatting with your brain. Many important messengers, such as serotonin, our “happiness hormone,” are produced here to a large extent.
• They're your little nutrient factories: Your gut bacteria don't just help with digestion; they also produce vital vitamins, such as vitamin K and various B vitamins.

Understand your body's signals

Your body is constantly communicating with you. Often, the signs are subtle, indicating that your microbiome has become imbalanced. Once you learn to interpret these signals correctly, you have already taken the first and most important step toward improvement.

Your body sends signals. This table summarizes which symptoms may indicate an imbalance in the gut.

Common signs of an imbalanced gut flora

Body area	Possible signs and symptoms
Digestion	Bloating, feeling full, constipation, diarrhea, irritable bowel symptoms
Skin	Acne, eczema, rosacea, dry skin
Immune system	Frequent infections, allergies, food intolerances
Mind & energy	Mood swings, fatigue, difficulty concentrating, depressive moods
General	Joint pain, unexplained weight gain, cravings for sugar

Remember: These symptoms are only clues. But if you recognize yourself in several of these points, it's a strong indication that you should pay more attention to your gut.

Your path to greater well-being begins with understanding your body's language. Instead of ignoring symptoms, learn to use them as valuable clues about your gut health.

The figures also show that this topic is becoming increasingly important. The global probiotics market was estimated at an impressive USD 4.9 billion in 2023 and is expected to grow to USD 8.4 billion by 2033. This boom shows how many people now recognize the tremendous value of a healthy gut flora. You can read more about this market development at Spherical Insights.

Your individual starting point

But how should you best approach the whole thing? Before taking random probiotics or radically changing your diet, an honest assessment of your current situation is essential. Every person is unique—and so is their microbiome.

A mybody®x gut microbiome test is like a detailed map of your gut. It provides a precise analysis of your bacterial diversity and shows you in black and white exactly where an imbalance exists. With this knowledge, you can tailor the recommendations from this guide to your needs and achieve significantly faster—and, above all, more sustainable—results on your path to better health.

The right nutrients for your microbiome

To build up your gut flora sustainably, imagine your beneficial gut bacteria as small, demanding pets. They need the right food to multiply and carry out their important work for you. This special food is known as prebiotics.

Prebiotics are nothing more than certain indigestible fibers. While you can't digest them, your good bacteria eagerly feast on them. When these fibers are fermented, short-chain fatty acids such as the valuable butyrate are produced. It's practically super fuel for your intestinal wall cells, keeping them fit and strengthening your gut barrier from within.

Your gut-friendly meal plan

The good news is: You don't have to rush to an organic food store and buy expensive exotic products. You can find many of the best prebiotic foods right in a regular supermarket.

Some true powerhouses for your gut are:

• Chicory: One of the best sources of the fiber inulin. Just a few leaves in a salad make a difference.
• Jerusalem artichoke: This nutty-flavored tuber is a fantastic vegetable side dish or base for a purée.
• Leeks, onions, and garlic: These kitchen classics are not just for seasoning; they are also genuine power food for your microbiome.
• Asparagus: Especially when it is in season, it is a delicious and gut-friendly choice.

But everyday foods can also make a huge contribution. Regularly include oatmeal, legumes such as lentils or chickpeas, and—our insider tip—slightly green bananas in your diet. The latter are packed with resistant starch, another top food source for your gut inhabitants.

The true key to success lies in variety. Think of it as a colorful buffet for your gut bacteria. Instead of focusing on just one or two foods, offer them a varied diet. Each type of bacteria has its own preferences—the more colorful your plate, the more diverse and resilient your microbiome will become.

To make the right choices at the supermarket, it is invaluable to be able to read labels. A good understanding of food labeling helps you uncover hidden sugar and specifically choose fiber-rich products.

Soluble vs. insoluble fiber

When we talk about fiber, we actually mean two different types, both of which are essential for your gut health. It is important to know the difference.

Soluble fiber: They absorb water in the gut and form a kind of gel. This provides a pleasant, long-lasting feeling of fullness and prevents blood sugar spikes. Above all, they are food (prebiotics) for your beneficial gut bacteria.

• Sources: Oats, barley, flaxseeds, apples, carrots, legumes

Insoluble fiber: These pass through the gut almost unchanged. Their main purpose is to increase stool volume and stimulate bowel movements. They act like a gentle, natural “brush” for your gut, making them an excellent remedy for constipation.

• Sources: Whole-grain products, nuts, seeds, and the skins of fruits and vegetables

A truly gut-healthy diet always combines both types. A breakfast of oatmeal (soluble) with a handful of nuts (insoluble) and a few berries (both) is therefore an absolutely perfect way to start the day.

Get reinforcements: Fermented foods as natural probiotics

After looking at the right “food” for your hard-working gut bacteria, it’s time to recruit new, powerful team members. This is where fermented foods come in. They are a delicious and completely natural source of probiotics—living, beneficial microorganisms that directly support your existing gut team.

Something magical happens during fermentation: bacteria or yeasts transform the sugars in food into valuable substances such as lactic acid. This process not only preserves the food but also creates an army of beneficial bacteria that build a healthy gut microbiome and enrich its diversity.

The best probiotic helpers for your meal plan

The good news? You don’t have to look far to incorporate these powerhouses into your diet. You can find many fermented products at the supermarket and easily add them to your meals.

• Plain yogurt & kefir: The absolute classics. They are rich in lactobacilli and bifidobacteria. Kefir, often known as the “drink of centenarians,” is the secret star here—it contains an even greater variety of bacteria and yeasts than yogurt.

• Real sauerkraut: Be careful—you need to look closely here! Typical sauerkraut from a jar or can is usually pasteurized, meaning it has been heated. Unfortunately, this kills the valuable live cultures. Instead, opt for fresh, refrigerated sauerkraut from a health food store or organic grocery store.

• Kimchi: This Korean national dish made from fermented napa cabbage is a true explosion of flavor and provides an impressive amount of lactic acid bacteria. It is a fantastic, spicy side dish for many meals. If you’re curious about what other benefits kimchi offers, you can learn more about kimchi and its effects on the gut microbiome in our article.

• Kombucha: This fermented tea drink is a refreshing, lightly sparkling alternative to sugary soft drinks. Here too, look for unpasteurized varieties with as little sugar as possible.

Science confirms that these foods are more than just a trend. A widely recognized study by Stanford School of Medicine examined exactly this: Participants who ate many fermented products showed significantly greater diversity in their gut bacteria. At the same time, levels of 19 different inflammatory markers in the blood decreased—including interleukin-6, which is associated with chronic conditions such as arthritis and type 2 diabetes. If you’d like to explore the research in greater depth, you can read more about the study results on Focus.

How to get started easily

The key is not to view these foods as a rare exception, but to make them a regular part of your meal plan. Start slowly, with small portions, so your digestive system can adjust to the new microorganisms.

How to make integration easy:

Foods	Simple to incorporate into everyday life
Kefir	A small glass at breakfast or as a creamy base for your smoothie.
Sauerkraut	One or two forkfuls as a crunchy side dish with lunch or as a topping for your salad.
Kimchi	A small portion with rice dishes, in a bowl, or—if you’re feeling adventurous—on avocado toast.
Yogurt	As a snack between meals with a few nuts or as a base for a fresh salad dressing.

Think of fermented foods as daily reinforcement for your microbiome. Small amounts consumed regularly have a greater effect than a large portion once a month. Consistency is your key to success here.

For full control: Simply ferment it yourself

If you want full control over the ingredients and freshness, fermenting your own food is a worthwhile and surprisingly simple option. You don’t need expensive equipment and can get started right away.

Water kefir is a perfect beginner project. All you need is water kefir grains (available online), water, sugar (as food for the cultures), and a large jar. Within 24 to 48 hours, you’ll have your own probiotic drink, which you can flavor with fruit as you like.

Vegetables are also incredibly easy to ferment. Simply chop your favorite vegetables (e.g., carrots, beetroot), place them in a jar with a brine (approx. 2% salt content), and make sure everything is well covered with liquid. After a few days at room temperature, fermentation begins—simple, inexpensive, and incredibly healthy.

Your lifestyle as the key to gut health

Your diet is the foundation, no question. But to build a truly stable, healthy gut flora, we need to look beyond food. Your overall lifestyle is the real game-changer here. Often, it is precisely the things we overlook amid everyday stress—stress, sleep, and exercise—that ultimately make the crucial difference. They shape your microbiome just as sustainably as any meal.

Did you know that your gut and brain are constantly chatting with each other? This direct connection is called the gut-brain axis. In practical terms, this means that when you feel stressed, your gut senses it immediately. During chronic stress, your brain sends out alarm signals that negatively alter the composition of your gut bacteria. Diversity decreases, and inflammation-promoting bacteria suddenly gain the upper hand.

Stress management is gut care

Constant stress is pure poison for your beneficial gut bacteria. It can make your gut's protective barrier more permeable (the so-called "leaky gut") and thereby open the floodgates to inflammation throughout the body. The good news: You can actively counteract this, and it does not have to be complicated.

Regular relaxation is not a luxury but an absolute necessity for your gut. Find out what works for you:

• Conscious breathing: Just three to five minutes of deep abdominal breathing can immediately calm your nervous system and slow down the stress response.
• Time in nature: A walk in the park or forest has been shown to lower the stress hormone cortisol. You can feel it immediately.
• Gentle exercise: Yoga or tai chi are perfect. They combine movement with mindfulness and help you let go mentally and physically.

A healthy lifestyle also means dealing honestly with mental stress. If you notice that the pressure is becoming too much, it is important to recognize the signs. Learn how to recognize and manage psychological stress, because chronic stress is the direct adversary of your gut health.

Exercise your microbiome loves

Regular exercise is another lever for building up your gut flora. Studies clearly show that physically active people have a much greater diversity of beneficial bacteria. Exercise stimulates intestinal activity, promotes circulation, and boosts the production of gut-protective butyrate—essentially superfood for your intestinal lining.

The right amount is crucial here. Moderate activities are ideal:

• Brisk walking
• Cycling
• Swimming
• Dancing

But be careful: Overtraining can have the exact opposite effect. Excessive exercise is pure stress for the body. It can weaken the gut barrier and even promote inflammation. Listen to your body and find a good balance between activity and recovery.

Just as your gut needs a variety of nutrients, it also benefits from a varied mix of sleep, relaxation, and exercise. See these three pillars as an inseparable unit that together forms the foundation for your well-being.

Sleep: The most important phase of regeneration

While you sleep, your body is working at full speed to repair itself—and this applies especially to your intestinal lining. Sufficient, restful sleep is essential for renewing intestinal cells and keeping the gut barrier strong. Sleep deprivation severely disrupts this process and can throw the composition of your microbiome out of balance.

Simple tips for better sleep:

Measure	Why it helps
Consistent sleep schedule	Supports your natural biorhythm (circadian rhythm) and greatly improves sleep quality.
Avoid screens	The blue light from phones & co. inhibits the production of the sleep hormone melatonin. Put them away at least an hour beforehand!
Cool, dark room	Create an optimal sleeping environment and signal to your body that it is time to rest.

The importance of a healthy gut flora really cannot be underestimated. A disturbed gut flora is considered a significant risk factor for many chronic diseases. The Robert Koch Institute (RKI) reports that almost one in two people will develop cancer at some point in their lifetime—and the microbiome plays a crucial role in the development and progression of inflammation.

The right way to use antibiotics

Sometimes they’re unavoidable. Antibiotics are often lifesaving. The problem is that they cannot distinguish between good and bad bacteria and usually leave considerable collateral damage in your microbiome. If you have to take an antibiotic, you can still actively support your gut at the same time.

• Feed your good bacteria: Provide the survivors with plenty of prebiotic food from fiber-rich sources (vegetables, legumes, whole grains).
• Include probiotics: Eat fermented foods such as kefir, yogurt, or unpasteurized sauerkraut. Important: Leave an interval of 2–3 hours between consuming them and taking the antibiotic.
• Stay the course: Continue the gut-friendly diet consistently after treatment to speed up recovery. Whether specific nutrients or probiotics could also benefit you can be determined with a targeted mybody®x nutrient test or gut microbiome test.

When a gut microbiome test is truly worthwhile

You are really making an effort: You are eating more fiber, have incorporated fermented foods into your daily routine, and are paying attention to a healthy lifestyle. Yet your digestive problems, skin blemishes, or that constant fatigue simply will not go away? Or perhaps you are still at the very beginning and do not want to grope around in the dark, but instead start out with a targeted approach from day one and avoid unnecessary detours.

Well-intentioned advice such as “Just eat more vegetables” is often not the solution when the problems lie deeper. If your symptoms persist despite all your efforts, it is time to take a closer look. This is exactly where a precise analysis of your gut can make all the difference. It is the step from guessing to knowing.

When general advice reaches its limits

A gut microbiome test is not a miracle cure, but an incredibly valuable tool in certain situations. Think of it as looking under the hood of your body. When your car starts sputtering, you do not simply start replacing parts at random. You look for the cause. We should take the same approach with our gut.

An analysis is especially valuable in these cases:

• For chronic digestive problems: You have been suffering from bloating, constipation, or diarrhea for months or even years, and nothing seems to really help.
• For unexplained intolerances: You feel like you are reacting to more and more foods, but cannot identify a clear pattern.
• After antibiotic treatment: You want to specifically restore the right bacterial strains that are important for you instead of simply taking random probiotics.
• For persistent skin conditions: Problems such as acne, eczema, or rosacea often have their roots in an imbalance in the gut.
• For targeted prevention: You actually feel well, but want to proactively understand the state of your microbiome to safeguard your well-being in the long term.

A test does not just tell you that something is wrong—you have probably felt that yourself for a long time. It shows you what exactly is happening in your gut. And that knowledge is the difference between blindly trying things out and following a targeted strategy.

What a test specifically tells you

With the mybody®x gut microbiome test, you receive a detailed snapshot of your inner ecosystem. The best part: You do not even have to leave home. Sample collection is simple and discreet in the comfort of your own home. Our certified laboratory in Germany analyzes your sample and translates the complex data into a report you can actually understand.

For example, you will learn:

• What your bacterial diversity looks like: High diversity is a clear sign of a resilient, healthy microbiome.
• Whether you’re missing important bacterial genera: Could you be lacking essential helpers such as lactobacilli or bifidobacteria?
• Whether inflammation-promoting microbes have gained the upper hand: Sometimes certain problematic bacteria are responsible for your symptoms.
• Your individual enterotype profile: This provides insight into the basic composition of your gut flora and how your body processes nutrients.

This precise information is the key to truly building a healthy gut flora. Instead of remaining uncertain, you can finally take targeted action. You can also learn more about the exact process and background in our detailed article on the gut test at mybody-x.com.

Personalized recommendations instead of general advice

But the greatest benefit of a test lies in its personalized recommendations for action. Your results report isn’t a generic off-the-shelf document. It’s a guide tailored to you and your microbiome that goes far beyond what you’ll find in general guides.

Your personalized report includes, for example:

Category	Your personalized recommendations
Nutrition	Specific suggestions for prebiotic foods that feed exactly the bacterial strains underrepresented in your gut.
Probiotics	Targeted recommendations for probiotic strains that can compensate for your individual deficiency—instead of simply eating any yogurt.
Lifestyle	Personalized tips for exercise and stress management, based on how your microbiome responds to these factors.

With this knowledge, you’re investing in your health in a targeted and effective way. You no longer buy random supplements without knowing whether you even need them. Instead, you give your body exactly what it needs to restore balance. It’s the most direct path to sustainable well-being.

Your path to sustainable well-being

Building a healthy gut flora is a marathon, not a sprint. This may be the most important sentence to keep reminding yourself of along the way. It’s crucial to have realistic expectations and give your body the time it needs for this important transition. Your microbiome is a complex ecosystem that doesn’t reorganize itself overnight.

Our most important practical advice: Focus on consistency rather than perfection. It’s not about never making another mistake from now on. Much more important is creating a lasting gut-friendly foundation in your everyday life that suits you and that you can maintain over the long term.

A realistic timeline for your gut health

How quickly you notice changes is completely individual and depends largely on where you are starting from. However, a rough timeline can help you stay on track and put your progress into perspective.

• After 2 to 4 weeks: The first positive effects are often already noticeable at this point. You may find that your digestion becomes more regular, bloating subsides, or you simply feel better after eating. Many people also report a slight increase in their energy levels.

• After 2 to 3 months: During this phase, the positive changes begin to stabilize. Your microbiome adapts to the new, nutrient-rich diet. You may also notice improvements in your skin or overall mood.

• After 6 months and beyond: Profound and lasting changes to your microbiome take time. After around six months of consistent adjustments, you will have built a solid foundation for a diverse and resilient gut microbiome that supports you in the long term.

Every single step on this journey is a valuable investment in your long-term health and quality of life. Celebrate the small successes too, and be patient with yourself and your body—it is working incredibly hard for you right now.

The journey from the initial analysis to your personalized recommendations is incredibly simple. This graphic shows you what the process looks like with a mybody®x gut test.

The entire process is designed to give you clarity quickly and easily: You start by collecting a sample at home, our certified laboratory carries out the scientific analysis, and based on the results, you receive personalized, actionable recommendations.

Listen to your body's signals

Your body is your best compass on this journey. Learn to listen to its signals again. Do you feel energized after a meal, or rather sluggish and tired? How does your digestion respond to certain foods?

Consider documenting your observations, perhaps even in a small journal. This will help you gradually recognize patterns and better understand what truly benefits you and your gut. Building a healthy gut microbiome is a very personal journey—a journey on which you learn to rebuild a strong and honest connection with your body.

On your journey toward a healthy gut, the same questions are sure to come up again and again. That is perfectly normal. We have gathered the most important ones here and shed light on the subject—without any technical jargon, so you know exactly what really matters when improving your gut health.

How quickly will I notice the first results from improving my gut health?

This is one of the most common and important questions, because of course you want quick results. The good news is that your body often responds surprisingly quickly. Many people notice the first positive changes, such as more regular digestion, less bloating, or simply feeling better in their gut, after just two to four weeks. Give your gut this time to adjust to the new, healthier lifestyle.

Building a truly stable and diverse gut flora is a marathon, not a sprint. Realistically, you should plan on three to six months. During this time, the new beneficial bacteria become established and create a resilient ecosystem.

Do I absolutely need probiotic capsules?

Not necessarily. The absolute foundation of a healthy gut remains a diet rich in prebiotic fiber (food for your beneficial bacteria) and fermented foods. This alone is often enough to achieve impressive progress.

Targeted probiotics can be a real game-changer in certain situations. This is especially true after antibiotic treatment, which unfortunately does not distinguish between good and bad bacteria. If a mybody®x gut microbiome test reveals specific deficiencies, targeted supplementation can also be extremely valuable. Then you know exactly which bacterial strains are missing and can supplement them precisely.

Is sugar really that bad for my gut?

Here, the answer is a clear and emphatic yes. Excessive sugar consumption is like fast food for the harmful bacteria and yeast in your gut. It allows them to grow and thrive, quickly tipping the delicate balance in their favor.

Reducing your intake of added sugar is therefore one of the most effective steps you can take. This deprives the troublemakers of their food source and gives your beneficial bacteria the chance to reestablish themselves and gain the upper hand.
