Probiotics

You may already have of Probiotics You've heard of them, but what are they and how can they affect your health? What do they have to do with the microbiome and what role does our diet play? Let's dive deeper in this article and learn more about these little helpers.

The microbiome: A world full of bacteria

First, a brief explanation of terms before we get started: Our body is a complex ecosystem inhabited by trillions of microorganisms. This system, known as Microbiom, is home to a variety of bacteria that play a crucial role in our health. The microbiome is found in our gut, on our skin and in other areas of our body and affects everything from our digestion to our immune system. In recent years, new studies have been published that have shown how much the microbiome is involved in our health, but also in disease processes. For this reason, a change in the microbiome in the form of Dysbiosis also in the Hallmarks of Aging .

What are probiotics?

Probiotics are living microorganismsthat can have a positive impact on our health, especially on the health of our digestive system. These beneficial bacteria can help To support balance in the microbiome and keep the harmful bacteria at bay.

Probiotics, prebiotics and symbiotics: what is the difference?

Probiotics are living bacteriathat can have a positive impact on health. Prebiotics are indigestible dietary fibre, which promote the growth and activity of beneficial bacteria in the intestine. Symbiotics are products that contain both probiotics and prebiotics and thus support the synergistic effects of both.

How do probiotics work?

Probiotics are live microorganisms that, when consumed in sufficient quantities, can provide health benefits. Their effects are based on a variety of mechanisms that take place in the gut.

1. Improve digestion: Probiotics can aid digestion by helping to break down food and absorb nutrients. They produce enzymes that help break down complex carbohydrates, proteins and fats that the body cannot fully digest on its own.
2. Strengthening the immune system: Probiotics interact with the cells of the immune system in the gut and help regulate the activity and function of these cells. This can strengthen the body's defense responses against harmful microorganisms and reduce the risk of infections.
3. Reducing Inflammation: Some bacteria produce short-chain fatty acids Butyrate. These substances have anti-inflammatory properties and can help reduce inflammation in the gut and throughout the body. Butyrate, for example, is an important source of energy for the cells of the intestinal wall and supports the integrity of the intestinal mucosa.
4. Promoting the balance of the intestinal flora: Probiotics can help maintain or restore the balance between good and bad bacteria in the gut. They compete with harmful bacteria for nutrients and space in the gut and can thus inhibit the growth of pathogenic microorganisms.

Types of probiotics

There are many different types of probiotics, including Lactobacillus, Bifidobacterium, and Saccharomyces boulardii. Each type has its own specific benefits and can help support different aspects of health. Let's take a closer look:

1. Lactobacillus: These bacteria are one of the Most common types of probiotics and are found in many fermented foods such as yogurt and kefir. Lactobacillus strains may help improve gut health by aiding digestion, promoting the production of healthy gut bacteria, and boosting immunity.
2. Bifidobacterium: These bacteria are found mainly in the lower parts of the digestive tract, such as the large intestine. Bifidobacterium strains play an important role in Digestion of fiber, the synthesis of vitamins and the strengthening of the intestinal barrier. They can also help reduce inflammation and strengthen the immune system.
3. Saccharomyces boulardii: Unlike most probiotics, Saccharomyces boulardii is a Yeast typeThis special yeast can help restore balance in the intestine, especially after antibiotic treatment or gastrointestinal infections. Saccharomyces boulardii may also help reduce diarrhea and speed up the restoration of intestinal flora.

Where can I find probiotics?

Probiotics are available in several forms, including:

1. Yogurt: Yogurt is one of the most well-known sources of probiotics. Look for the mention of “live and active cultures” on the packaging to make sure it contains probiotics.
2. Kefir: Kefir is a fermented milk drink that is rich in probiotics. It has a slightly sour taste and is a refreshing alternative to yogurt.
3. Sauerkraut: Sauerkraut is fermented cabbage and an excellent source of probiotics. It goes well with sandwiches or as a side dish to various dishes.
4. Kimchi: Kimchi is a Korean fermented vegetable that is also rich in probiotics. It has a spicy taste and can be used as a side dish or as an ingredient in various dishes.
5. miso: Miso is a fermented soybean paste commonly used in Japanese cuisine. It adds a rich, umami flavor to soups and dressings while also providing probiotics.
6. Kombucha: Kombucha is a fermented tea drink made by fermenting sugar with the help of bacteria and yeast. It is refreshing and can be found in a variety of flavors.
7. tempeh: Tempeh is a fermented soy product and an excellent plant-based source of probiotics. It can be fried, grilled or used in curries.

The study situation

Research on probiotics has increased significantly in recent years, and many studies have been conducted to investigate their potential benefits. Two notable studies that have shown positive results for human health are:

Study to improve intestinal health: A randomized controlled trial published in the journal “Gastroenterology” examined the effects of a specific Lactobacillus rhamnosus strain on the intestinal health of participants with irritable bowel syndrome (IBS). The results showed a significant improvement in the symptoms of irritable bowel syndrome, including a reduction in bloating, abdominal pain and diarrhea.

Study to strengthen the immune system: A meta-analysis of randomized controlled trials published in the journal Nutrients examined the impact of taking probiotics on the immune system. The analysis found that regular intake of probiotics significantly reduced the risk of respiratory infections, especially in children and older adults. This suggests that probiotics may play an important role in strengthening the immune system.

These studies are just a few examples of the growing body of evidence for the beneficial effects of probiotics on human health. Although more research is needed to better understand the exact mechanisms and effects of probiotics, these studies provide promising evidence that probiotics may play an important role in promoting digestive and immune health.

Did you know?

The saying “You are what you eat” refers not only to the probiotics contained in food, but also to Fibres and secondary plant substances. These also have an influence on your microbiome. For example, studies have shown that the molecule apigenin, which can be found in parsley, suppresses bad bacteria and thus contributes to the symbiosis in your microbiome.

Health benefits

Regular intake of probiotics can provide a variety of health benefits, including improved digestion, a strengthened immune system, a reduction in inflammation and support for weight control.

Probiotics for weight loss: What do the studies say?

The idea that probiotics can help you lose weight sounds appealing, right? There are actually some studies that suggest that probiotics may play a role in weight loss. For example, a study published in the journal Obesity Reviews found that taking certain probiotics can help reduce body weight and decrease fat mass. However, more studies are needed to understand the exact mechanisms and effects.

When can I take probiotics?

Probiotics can be helpful in many situations, especially if you problems with digestion have or your want to strengthen your immune system. You can also take such preparations if you suffer from digestive problems such as bloating, diarrhea or constipation. They can also help restore the balance of your intestinal flora after antibiotic treatment.

How long should I take probiotics?

The duration of use may vary depending on the situation. If you have acute digestive problems, you may be able to for a few weeks until your symptoms improve. If you are taking probiotics to support your overall health, you can possibly take over a longer period of timeto maximize the effect on your immune system and digestion. However, it is always advisable to speak to a doctor or nutritionist to determine the correct dosage and duration of intake.

Are probiotics useful after antibiotics?

Absolutely! Antibiotics can not only kill the harmful bacteria, but also affect the beneficial bacteria in your gut. Taking Probiotics after antibiotic treatment can help restore the balance of your intestinal flora and reduce the risk of side effects such as diarrhea.

Are probiotics also advisable for children?

Yes, probiotics can be beneficial for children too. Studies have shown that taking probiotics in children can help reduce the risk of gastrointestinal infections and promote overall health. However, it is important to talk to a pediatrician before giving probiotics to your child to make sure it is appropriate for their age and health.

Why do I need fiber when taking probiotics?

Not only is fiber important for your digestion, it also plays a crucial role in supporting the probiotics in your gut. But why is it so important?

Dietary fiber is a complex carbohydratethat your body cannot digest. They serve as food for the good bacteria in your gut, including probiotics. If you take probiotics but don't eat enough fiber, the good bacteria may not get enough food to thrive and multiply, which could compromise their beneficial effects on your health.

A diet rich in fibre is therefore crucial to support the effects of probiotics and maintain a healthy balance in the intestine. Fiber is found mainly in foods such as Whole grain products, fruits, vegetables and legumes.

In addition, dr. Robert Lustig in his book “Metabolical: The Lure and the Lies of Processed Food, Nutrition, and Modern Medicine” pointed out that dietary fibre also plays an important role in Regulation of blood sugar levels and prevention of metabolic diseases By slowing the rate at which carbohydrates are broken down in your digestive system, fiber can help prevent blood sugar spikes and keep insulin levels stable. insulin resistance prevent and even your blood lipid levels influence positively.

The scope of MAP was expanded in two key areas: Fasting has an impact on your microbiome. Studies have shown that iIntermittent fasting can promote the growth of certain probiotic bacterial strains in the gut. 

What is the gut-brain axis and how do probiotics influence it?

The Gut-brain axis is a fascinating concept that shows the close connection between our gut and our brain. It is one of Network of communication channels, which is mediated by various signals and neurotransmitters. These signals can be flow in both directions, whereby the gut can influence the brain and vice versa the brain can influence the gut. Some people perceive this connection as “Gut feeling” true.

Probiotics play an important role in influencing this gut-brain axis. They can regulate the balance of bacteria in our gut by increasing the number and diversity of good bacteria and reducing harmful bacteria. These changes can help reduce inflammation in the gut and strengthen the barrier function of the intestinal wall.

Studies have shown that probiotics can actually have a direct effect on our brain. For example, a randomized, placebo-controlled study published in the journal “Gut Microbes” found that taking probiotics over a period of four weeks led to Vchanges in certain areas of the brain associated with the processing of emotions. Similar results have been found in other studies suggesting that probiotics may play a role in improving mood, stress management, and cognitive function.

In addition, probiotics can also Influence the production of neurotransmitters, the chemical messengers that mediate communication between nerve cells in the brain. For example, certain strains of probiotics can Increase production of serotonin, a neurotransmitter associated with feelings of happiness and mood elevation.

Overall, these findings show that probiotics are not only important for our digestion, but can also have a direct impact on our brain and our mood.

Conclusion

Probiotics are small but powerful helpers that can have a big impact on our health. By incorporating these helpers into your diet, you can help support the balance in your microbiome and improve your health in many ways.
