Rules for a Healthy Gut

The health of the gut is fundamental to overall human well-being. It performs a myriad of important functions that not only support digestion but also influence the immune system and the body’s overall condition. The gut is the center of digestion in the human body. It is responsible for breaking down and absorbing nutrients from the food entering the body. Thanks to its work, nutrients from food enter the bloodstream and are transported to the cells and tissues of the body, ensuring their vitality.

Additionally, it is an important component of the body’s immune system. It contains a vast number of immune system cells that protect the body from harmful microorganisms and infections. The majority of the immune system is located in the gut, underscoring its importance for maintaining overall health.

The gut microbiota, or microbiome, is an extensive community of bacteria residing in the gut. This microbiome helps break down food, synthesize certain vitamins, and strengthen the immune system. Imbalance in the microbiome can lead to various diseases and conditions, such as irritable bowel syndrome, inflammatory diseases, and other disorders.


Diet for a Healthy Gut


Proper nutrition not only provides our bodies with essential nutrients but also plays a significant role in gut health. The gut is not just a digestive system; it is a complex organ with its own ecosystem, which includes thousands of different bacterial species known as gut microbiota. This microbiome performs many important functions, from digesting food to supporting the immune system.


The Importance of Nutrients for the Gut


Some dietary components, especially dietary fibers, serve as a source of energy for beneficial bacteria in the gut. This helps maintain the balance of the microbiota and prevents the growth of harmful bacteria. Dietary fibers also play a key role in maintaining normal peristalsis—the movement that helps move food through the intestines. Consuming an adequate amount of fiber helps prevent constipation and ensures the normal functioning of the gut.

To maintain gut health, include fiber-rich foods in your diet:

  • Fruits and vegetables: Bright and diverse fruits and vegetables, such as apples, pears, broccoli, spinach, and carrots, are excellent sources of dietary fiber.
  • Whole grains: Prefer whole grain products such as oatmeal, quinoa, brown rice, and barley, which are rich in dietary fiber and other nutrients.
  • Legumes: Lentils, beans, peas, and other legumes are excellent sources of plant-based protein and dietary fiber.
  • Nuts and seeds: Almonds, walnuts, chia seeds, flaxseeds, and other nuts and seeds contain beneficial fats and dietary fiber that promote gut health.

Foods that Promote a Healthy Microbiota


  1. Fruits and vegetables: Fresh fruits and vegetables contain a large amount of soluble and insoluble dietary fiber, which not only improves peristalsis but also serves as a food source for beneficial bacteria in the gut. Red fruits and vegetables, such as berries, cherries, red peppers, and tomatoes, are particularly beneficial due to their antioxidant content.
  2. Whole grains: Oats, barley, brown rice, wheat, and other whole grains are rich in dietary fiber, which promotes normal gut function and supports a healthy microbiota.
  3. Legumes: Lentils, beans, peas, and other legumes are excellent sources of soluble and insoluble fibers, which improve digestion and stimulate the growth of beneficial bacteria in the gut.
  4. Nuts and seeds: Almonds, walnuts, flaxseeds, chia seeds, and other nuts and seeds are rich in dietary fiber and healthy fats, which have a positive effect on gut microbiota.


Recommendations for Fiber Intake


Increase your intake of vegetables and fruits: aim to consume at least 5 servings of vegetables and fruits per day. They should be varied to provide a variety of nutrients and fibers.

Prefer whole grains: replace regular white flour products with their whole grain counterparts, such as whole grain bread, whole grain cereals, and whole grain pasta.

Add legumes to your diet: include legumes in your daily menu, such as adding them to soups, salads, or side dishes.

Healthy snacks: try snacks based on nuts and seeds, such as nuts with fruits or chia seeds added to yogurt.


Probiotics and Their Role in Gut Health


Probiotics are live microorganisms that, when consumed in sufficient quantities, can have a beneficial effect on the body, especially on the condition of the gut. These friendly bacteria can restore the balance of the microbiome, improve digestion, and support immunity. Let’s consider their role and how to choose the right probiotics for your health.


Types of Probiotics and Their Effects


Probiotics are various types of bacteria and yeasts that are beneficial for our health. They can include a wide range of microorganisms such as Lactobacillus, Bifidobacterium, Streptococcus, and Saccharomyces. Here’s what functions they can perform:

Restoring microbiome balance: Probiotics can help restore the balance between “good” and “bad” bacteria in the gut, promoting the normal functioning of the gastrointestinal tract.

Improving digestion: Probiotics can help improve digestion by aiding in the breakdown of food and absorption of nutrients.

Supporting immunity: Some probiotics can boost the immune system, helping the body fight infections and diseases.

When choosing probiotic products, it’s important to pay attention to the following aspects:

Live culture content: Make sure the chosen product contains live probiotic cultures, as they are the ones that can have a positive effect on your body.

Alignment of strains with claimed effects: Different strains of probiotics can perform different functions. When choosing a product, make sure that the strains it contains align with the claimed effects and goals of your probiotic intake.


Remember that consulting with a doctor or dietitian can help you choose suitable probiotics considering your individual needs and characteristics. The right choice of probiotics and their regular intake can significantly improve the health of your gut.


Prebiotics: The Secret to a Healthy Gut


Prebiotics are insoluble dietary fibers that not only serve as food for beneficial bacteria in the gut but also promote their growth and multiplication. Understanding their role and which products you can include in your diet to maintain gut health is important.


Prebiotics are an integral part of a healthy diet. They are insoluble dietary fibers that are not absorbed in the upper parts of the digestive system but reach the colon, where they serve as food for beneficial bacteria. This helps increase the number and diversity of “good” bacteria in the gut, which in turn has a positive impact on the overall health of the body.


Prebiotics are found in various plant-based products. Here are a few examples of prebiotic-rich foods and their beneficial properties:


  • Onions and garlic: These vegetables contain inulin, a prebiotic fiber that promotes the growth of beneficial bacteria in the gut and improves digestion.
  • Artichokes and bananas: They also contain prebiotics such as fructooligosaccharides, which promote the growth of beneficial bacteria and improve gut health.
  • Oats and apples: Rich in dietary fiber, they also contain prebiotic substances that support a healthy gut microbiota and promote normal digestive function.

Including these products in your diet can help maintain a healthy balance of microbiota and improve digestion. Regular consumption of prebiotics is one of the keys to a healthy and balanced diet.


Preventing Leaky Gut Syndrome


Leaky gut syndrome is not only the ability of its walls to pass nutrients but also to protect the body from harmful substances and microorganisms. This balance ensures the normal functioning of the digestive system and protects the body from the development of various diseases, including allergies, inflammatory processes, and autoimmune disorders.


When the permeability of the intestines is disrupted, which can occur under the influence of various factors such as improper diet, stress, or inflammation, this can lead to the penetration of harmful substances and microorganisms into the bloodstream. This condition, known as “increased intestinal permeability” or “leaky gut,” can cause many diseases and health problems.


To prevent disruptions in intestinal permeability and maintain its health, the following is recommended:

  • Avoid inflammatory foods: Some products, such as gluten, sugar, and processed foods, can contribute to inflammation in the body and increased intestinal permeability. Excluding or limiting such products from your diet can help improve the condition of the gut.
  • Include gut-supporting foods in your diet: Fruits, vegetables, whole grains, legumes, and nuts are a source of food for beneficial bacteria in the gut. Moderate consumption of these products helps maintain a healthy microbiota and strengthen the intestinal walls.
  • Lead a healthy lifestyle: Regular physical activity helps improve intestinal peristalsis and overall digestive system health. It is also important to manage stress, as it can negatively affect the condition of the gut microbiota.


Lifestyle Recommendations for Maintaining Gut Health


Maintain normal hydration in the body. Water is a key component for the normal functioning of the gut, helping to maintain its moisture and facilitate the movement of food masses through the digestive tract. It is recommended to consume an adequate amount of water throughout the day to prevent dehydration and ensure proper functioning of the gut.


Physical activity is also important for gut health. Regular exercise helps stimulate peristalsis – the contractions of the intestinal muscles that promote the movement of food masses. This improves microcirculation in the walls of the intestine, providing oxygen and nutrients to its cells, which contributes to their health and functioning.


Stress is a natural reaction of the body to various physical and emotional factors, but its prolonged effect can negatively affect the condition of the intestinal microbiota. High levels of stress can lead to an imbalance in the microbiome, increasing the risk of various digestive system disorders, such as irritable bowel syndrome (IBS), inflammatory bowel diseases, and others.


The health of the gut plays a crucial role in overall well-being. It serves not only as the center of digestion but also as the key to maintaining immunity and overall bodily health. Maintaining gut health requires a systematic and targeted approach, including proper nutrition, consumption of probiotics and prebiotics, as well as maintaining a healthy lifestyle.

Caring for the gut should be consistent and systematic. Regular consumption of fiber-rich foods and gut-friendly bacteria, along with maintaining a healthy lifestyle, are not just temporary measures but a way of life that promotes health and well-being.

In case of questions or issues related to gut health, it is important to consult qualified specialists. Gastroenterologists and dieticians can assist in developing an individual gut support program and provide necessary recommendations for improvement.

Taking care of your gut is taking care of your overall health and well-being. Keep it in good condition, and your body will thank you for it for years to come.
