How to Improve Gut Health

Improving Gut Health – Why Is It Important?

Think of the gut flora as a highly specialized ecosystem in which the trillions of bacteria each have specific functions, from digesting certain foods to producing vital vitamins or fatty acids.

But why is the intestinal flora so essential for our health?

On the one hand, the microbiome is central to digestion and helps our body to extract and absorb nutrients from food. Secondly, the intestinal flora plays a key role in our immune system. Around 70% of our immune system is located in the gut, and a healthy gut flora can protect us from pathogens by forming a barrier and communicating with our brain to ensure an appropriate immune response. A healthy gut is, therefore, essential for a functioning immune defense. [1]

In addition, the gut flora influences our mood and brain, which is explained by the gut-brain axis. An imbalance in gut flora has been linked to a number of conditions, including digestive disorders, autoimmune diseases, and mental health problems such as depression. [2]

So, by nourishing, balancing and improving your gut flora, you can positively impact not only your digestive health but also your immune system, mental health, and overall well-being.

What is the role of intestinal flora?

The gut flora has various important functions:

1. Digestion: It aids in breaking down food and absorbing nutrients.
2. Vitamin Production: It is capable of producing vitamins, particularly B vitamins.
3. Protection Against Pathogens: It can displace harmful invaders, thereby preventing infections.
4. Immune System Support: It can activate immune cells and regulate inflammatory processes.
5. Maintenance of the Intestinal Mucosa: It forms a protective barrier that prevents toxins and pathogens from entering.
6. Metabolic Regulation: It helps utilize dietary fiber and produces short-chain fatty acids essential for energy metabolism.
7. Cholesterol Control: Some bacteria help lower blood cholesterol levels by binding bile acids.
8. Prevention of Urinary Tract Infections: By balancing microbes, it prevents harmful bacteria from colonizing the urinary tract.
9. Blood Sugar Regulation: It influences glucose metabolism and can help stabilize blood sugar levels.
10. Impact on Mood and Behavior: Through the gut-brain axis, the microbiome communicates with the brain, influencing emotions and cognitive functions.
11. Anti-inflammatory Effects: It reduces systemic inflammation, which is especially important in chronic diseases.
12. Allergy Prevention: It can modulate the immune response to reduce overreactions like allergies.
13. Weight Control: The microbiome influences energy balance and fat absorption, affecting body weight.
14. Detoxification: It supports the breakdown and elimination of harmful substances and toxins from food.

How Can I Recognize a Disturbed Microbiome?

Impaired gut flora, known as dysbiosis, can manifest itself through various symptoms, ranging from mild discomfort to serious health issues. [3] [4]

Here are some of the most common signs of a disrupted gut flora:

• Digestive problems: The most common symptoms include bloating, constipation, diarrhea, and a general feeling of discomfort after eating. These problems occur when the balance of microorganisms in the gut is disturbed, affecting digestion and absorption of nutrients.
• Tiredness and fatigue: Imbalanced gut flora can impact the absorption of nutrients, leading to a lack of important vitamins and minerals. This can manifest in constant tiredness and exhaustion, even after a good night's sleep.
• Skin problems: Skin conditions like acne, eczema, and rosacea are often linked to dysbiosis. The skin is a mirror of your internal health, and imbalances in the gut can trigger inflammation that affects the skin.
• Compromised immune system: Impaired gut flora can lead to a weakened immune system, increasing your susceptibility to frequent colds, infections, and even autoimmune diseases.
• Mental health issues: There is a connection between the gut and brain, known as the gut-brain axis. Dysbiosis can, therefore, impact mood swings, depression, and anxiety. [2]
• Weight changes: Unexplained weight gain or loss can indicate a dysfunctional and disrupted gut flora. The microbiome is essential in regulating your metabolism and can alter how your body processes and stores nutrients.

How to Improve Gut Health?

To build, support, and maintain a healthy gut flora, you can take the following measures: [1]

• Establish a healthy diet: Consume a wide range of foods, especially high-fiber foods, as these can promote the diversity of your gut bacteria.
• Fermented foods: Incorporate fermented and probiotic foods such as yogurt, kefir, sauerkraut, and kimchi into your diet to benefit from probiotics.
• Prebiotic foods: Eat foods that contain prebiotic fibers, such as garlic, onions, leeks, asparagus, and bananas, to support the growth and nourishment of healthy gut bacteria.
• Cut down on sugar and artificial sweeteners: Reduce your intake of added sugars and sweeteners, which can promote the growth of harmful bacteria and yeasts in your gut.
• Drink enough: Water is essential for digestion and can help keep your gut healthy.
• Avoid unnecessary antibiotics and medications: Antibiotics and certain medications can damage your gut flora. Only use them when medically necessary and discuss possible alternatives with your doctor.
• Regular exercise: Physical activity can increase the diversity of gut bacteria and contribute to gut health overall.

Probiotics

Probiotics are important for a healthy gut since they are live microorganisms, usually strains of bacteria, that provide health benefits when consumed in sufficient quantities. They are found in fermented foods such as yogurt, kefir, sauerkraut, and in probiotic supplements.

Probiotics can support the balance of the gut microbiome and the gut lining by promoting the growth of beneficial bacteria, such as lactic acid bacteria, and helping to crowd out harmful bacteria. They are particularly important after antibiotic treatment as they can help repair the damage to the gut flora caused by antibiotics and regulate the gut flora. [5]

Prebiotics

Prebiotics are also capable of improving gut health. They are indigestible food components, often soluble fiber or carbohydrates, that serve as food for probiotic bacteria or are converted into short-chain fatty acids, positively affecting your health. They occur naturally in many foods, including onions, garlic, chicory, bananas, and oats.

Prebiotics promote the growth and activity of healthy gut bacteria, especially bifidobacteria, and lactobacilli, and support a healthy gut by maintaining healthy gut. [6]

Synbiotics

Combining probiotics and prebiotics can be particularly effective as they work together to build and maintain a healthy gut flora. This synergy is called a synbiotic. Incorporating both probiotic and prebiotic foods into your diet can be a key element in promoting the health and balance of your gut flora and, therefore, improving your overall well-being. [7]

How to Fix Gut Microbiome With a Gut Cleanse?

A gut cleanse is a process that aims to improve or restore the balance of microorganisms in the digestive tract. It is often performed to combat the negative effects of disrupted gut flora, such as digestive discomfort, nutritional deficiencies, and a weakened immune system.

The main goal of colon cleansing is to reduce harmful bacteria and toxins, promote the health and diversity of beneficial gut bacteria, and strengthen the integrity of the intestinal mucosa. [8]

Achieve a Healthy Gut in 8 Steps

You can cleanse your gut with these 8 steps:

1. Change your diet: Start by reducing sugar, processed foods, alcohol, and foods rich in saturated fats. Instead, eat a varied, high-fiber diet with plenty of fresh vegetables, fruit, whole grains and fermented foods.
2. Integrate probiotics and prebiotics: Incorporate probiotic and prebiotic foods into your diet to promote the growth of beneficial gut bacteria. Probiotic supplements can also be considered, especially after antibiotic treatment.
3. Hydration: Drink enough water to aid your digestion and facilitate the elimination of toxins.
4. Avoid pollutants: Avoid exposure to pollutants and chemicals that can affect your gut health. You can do this by starting to switch to organic foods to reduce your pesticide intake.
5. Exercise: Regular physical activity can promote bowel movement and support the growth of healthy gut bacteria.
6. Stress management: Stress can have a negative impact on your gut health. Therefore, practice techniques such as meditation, yoga, or deep breathing to reduce your stress levels.
7. Review medication intake: Discuss with your doctor the need for any antibiotic therapy and the duration of antibiotics and other medications that could affect your gut balance.
8. Get enough sleep: Lack of sleep can negatively affect gut health.

Good sources include whole grains, Jerusalem artichokes (topinambur), flax seeds, chia seeds, berries, apples, pears, carrots, and green leafy vegetables.

• Prebiotics: These specifically promote the growth of healthy bacteria in the gut. Prebiotic-rich foods include garlic, onions, leeks, asparagus, bananas, and chicory.

• Polyphenol-rich foods: Polyphenols can improve gut health by promoting the growth of probiotic bacteria and inhibiting pathogenic bacteria. They can be found in dark chocolate, green tea, blueberries, red wine, and nuts.

• Nuts and seeds: These contain fiber, healthy fats, and proteins that can support healthy gut flora. Almonds, chia seeds, and linseeds are particularly recommended.

• Pulses: Beans, lentils, and peas are good home remedies for building intestinal flora. They are rich in fiber, which is fermented by the gut bacteria, which promotes gut health. Please bear in mind that some legumes, such as lentils, need to be soaked in water beforehand so that your body can benefit from them and avoid intestinal problems.

• Fatty fish: Omega-3 fatty acids in salmon, mackerel, and sardines can reduce inflammation in the body, which also supports gut health.

• Water and fluids: Good hydration is important for maintaining the lining of the gut and aids digestion.

Which Foods Disrupt Gut Health?

The following foods have a negative impact on your intestinal flora:

• Sugar and sweeteners: A high sugar intake can promote the growth of harmful bacteria and yeasts in the gut and cause inflammation and an imbalance in the gut flora. Artificial sweeteners can also have negative effects on gut bacteria. [3]

• Processed foods: They often contain additives, preservatives, and artificial colors that can affect gut health. Processed foods are also usually low in fiber, essential for healthy gut flora. [3]

• Trans fats: Trans fats found in many processed foods can promote inflammation and increase bowel disease risk.

• Alcohol: Excessive alcohol consumption can damage the intestinal mucosa, impair the production of stomach acid, and lead to an imbalance in the intestinal flora. [3]

• Red meat and processed meat: These contain certain chemicals that can be converted into harmful compounds by gut bacteria during digestion, which can increase the risk of bowel cancer. [3]

• Gluten-containing foods: In people with coeliac disease or gluten intolerance, consuming gluten can damage the intestinal lining and lead to an imbalance in the intestinal flora. [3]

Further Tips to Improve Gut Health

How else can you strengthen your gut flora? In addition to adjusting your diet and integrating certain foods into your diet, there are other tips that can help you build up a healthy microbiome:

• Natural supplements: certain supplements, such as L-glutamine, an amino acid supplement, can support the regeneration and integrity of the intestinal mucosa. Omega-3 fatty acids, found in fish oil, can also help reduce inflammation in the gut.

• Switch to organic foods: Try to minimize exposure to environmental pollutants and chemicals that can affect gut health. This includes switching to organic foods to reduce your intake of pesticides.

• Rethink hygiene practices: While good hygiene is important, excessive cleanliness, especially at a young age, can undermine the immune system and hinder the development of healthy gut flora. Natural contact with the environment and occasional exposure to microbes can be helpful.

• Chomp that food: Digestion begins in the mouth. Thorough chewing helps to break down food, which improves gut function and nutrient absorption.

• Eat mindfully: Eating in a hurry and under stress can affect digestion. Try to eat in a calm, relaxed environment and take time for your meals.

• Connect with nature: Spending time in nature can not only lower stress levels, but also increase exposure to a variety of microorganisms that potentially diversify gut flora.
