Good GUT Bacteria

What is Good GUT Bacteria?

All bacteria are not bad. There are more bacteria within us than cells. It is postulated that, there are  around 39 Trillion bacteria within us and they are predominantly seen in the large intestine. These bacteria are good for us, as they help in digestion, nutrient & drug metabolism, maintain the continuity and integrity of the Gut wall barrier, protect against harmful bacteria and also behave as immunomodulators.

In fact the GUT microbiome is very essential for maintenance of various human functions and wellness including mental wellness.  GUT health is important for overall human health.

Different Types of GUT Bacteria

There are several types of beneficial gut bacteria that are considered to be important for maintaining a healthy gut microbiome. Some of the commonly recognized ones include:

1. Bifidobacterium:

This genus of bacteria is known for its ability to ferment dietary fiber and produce short-chain fatty acids (SCFAs), which provide energy for the cells lining the colon.

2. Lactobacillus:

Lactobacillus species are lactic acid bacteria that are naturally found in the gastrointestinal tract. They are known for their role in fermenting carbohydrates and producing lactic acid.

3. Faecalibacterium Prausnitzii:

This species is one of the most abundant and important bacteria in the human gut. It produces butyrate, a short-chain fatty acid that has anti-inflammatory properties and is beneficial for maintaining gut health.

4. Akkermansia Muciniphila:

This bacterium resides in the mucosal layer of the gut and is associated with a healthy gut environment.

Escherichia Coli Nissle 1917:

This strain of Escherichia coli has been extensively studied and is commonly used as a probiotic. It has been shown to have beneficial effects in maintaining intestinal health and modulating the immune system.


Roseburia species are butyrate-producing bacteria that play a crucial role in breaking down complex carbohydrates.

It’s important to note that the composition of the gut microbiome varies among individuals, and what constitutes a “good” gut bacteria may vary depending on an individual’s specific health needs. A diverse and balanced gut microbiome is generally considered desirable for overall gut health. Consuming a varied and fiber-rich diet, including fermented foods, and considering probiotic supplementation under the guidance of a healthcare professional are some ways to promote a healthy gut microbiome.

Does the Type of Bacteria Vary from Region to Region?

Yes, the gut bacteria composition can vary among individuals from different countries or regions. Several factors influence the gut microbiome, including genetics, diet, lifestyle, environment, and cultural practices. As a result, the types and abundance of gut bacteria can differ across populations.

Diet plays a significant role in shaping the gut microbiome. Traditional dietary patterns vary among countries and cultures, leading to differences in the types of nutrients and fibers consumed. For example, diets rich in plant-based foods and fiber tend to support a more diverse microbiome, while diets high in processed foods and low in fiber can lead to a less diverse and less healthy gut microbiome.

Environmental Factors also influence the gut microbiome. Exposure to different climates, sanitation practices, and sources of water can impact the types of bacteria present in the gut.

Recent research has shown that geography can influence the gut microbiome composition as well. Studies comparing the gut bacteria of individuals from different countries or regions have revealed distinct microbial profiles. For instance, individuals from rural areas may have a higher abundance of certain bacteria associated with agricultural environments, while urban populations may have a microbiome composition influenced by urban lifestyles and dietary patterns.

It’s important to note that while there are regional differences in the gut microbiome, there is also a core set of bacteria that is commonly found across populations. Furthermore, an individual’s gut microbiome is not solely determined by their country of residence but is also influenced by various personal factors such as genetics, diet, and lifestyle choices.

Foods that Help Improve the Good GUT Bacteria:

Several natural foods can help improve the microbiome by providing beneficial nutrients and promoting the growth of good gut bacteria. Here are some examples:

1. Yogurt:

Yogurt contains live and active cultures of beneficial bacteria, such as Lactobacillus and Bifidobacterium. Look for yogurt labeled as containing “live and active cultures” to ensure you’re getting beneficial bacteria.

2. Kefir:

Kefir is a fermented dairy product that contains a variety of probiotic strains. It is rich in beneficial bacteria and yeasts that can help promote a healthy gut microbiome.

3. Sauerkraut:

Sauerkraut is fermented cabbage that contains Lactobacillus bacteria. Consuming sauerkraut or other fermented vegetables can introduce beneficial bacteria into the gut.

4. Kimchi:

Kimchi is a traditional Korean side dish made of fermented vegetables, including cabbage and radishes. It contains lactic acid bacteria and other beneficial microorganisms that can contribute to a healthy gut.

5. Kombucha:

Kombucha is a fermented tea beverage that contains a variety of beneficial bacteria and yeasts. It is known for its probiotic properties and can help support a healthy gut microbiome.

6. Garlic:

Garlic is a prebiotic food that serves as fuel for the growth of beneficial bacteria in the gut. It contains a compound called inulin, which acts as a prebiotic fiber.

7. Onions:

Onions are another prebiotic food rich in inulin and other fibers that can promote the growth of beneficial gut bacteria.

8. Jerusalem Artichokes:

Jerusalem artichokes, also known as sunchokes, are a root vegetable high in inulin. They can provide nourishment to the beneficial bacteria in the gut.

9. Apples:

Apples are a good source of soluble and insoluble fibers, including pectin, which can support the growth of beneficial bacteria in the gut.

10. Whole Grains:

Whole grains such as oats, brown rice, quinoa, and whole wheat contain fiber that can act as a prebiotic, feeding the good gut bacteria.

11. Legumes:

Legumes like lentils, chickpeas, and beans are rich in fiber and can help support a healthy gut microbiome.

12. Berries:

Berries are packed with antioxidants and fiber, which can provide nourishment for the gut bacteria.

Remember that it’s beneficial to include a variety of these foods in your diet to promote a diverse gut microbiome. Individual responses to these foods may vary, so listen to your body and make dietary choices that work well for you.
