What Does Gut Microbiome Refer to?

Fungi, bacteria, viruses, and many other microscopic organisms are known as microorganisms or microbes. You can find trillions of these microbes in your intestines or on your skin.  

There is a pocket in the large intestine, commonly known as the cecum, where most microbes are found. These microbes inside your large intestine's pocket are also called gut microbiomes. There are a multitude of microbes that reside inside you, but bacteria remain the most studied organism out of all.

You will be shocked to know that bacterial cells are more than human cells in your blood. On average, the number of bacterial cells is around 40 trillion, while the number of human cells is 30 trillion. In other words, our bodies contain more bacteria than human cells.

In addition to the above, there are more than one thousand species of bacteria in the human gut microbiome. Each of them has their significant roles and functions. Out of all, a few are highly vital for good health and to carry out essential functions.

The weight of these microbes may range from 2 to 5 pounds, which is equivalent to the weight of your brain. These microbes in the body function as an extra organ and conduct several important roles.

How Do Gut Bacteria Affect Mental Health?

Mood regulation stands out as one of the significant connections between gut health and mental health. Serotonin is produced by the gut, which is responsible for regulating moods. Most studies have shown a solid connection between low serotonin levels and the occurrence of mental health disorders such as anxiety and depression. If the bacteria residing in your gut are not operating properly, this can lead to issues in the production of one of the major brain chemicals named serotonin. As a consequence, it may lead to mood swings and other mental health disorders.

How we react to stress and gut bacteria are similarly affected by stress. The homeostasis in the gut microbiome assists in controlling the response of the following stress hormones: cortisol. If there is an imbalance in gut bacteria, the levels of stress hormones such as cortisols tend to increase. As a result, you are prone to develop unmanaged stress, depression, and anxiety.

There is a strong relationship between gut bacteria and the immune system. Most of our immune system is present in the gut. So, if the gut bacteria are imbalanced, this imbalance can contribute to chronic inflammation. This inflammation is often linked to mood disorders such as anxiety and depression. Having inflammation in the brain could affect how you think, behave, and feel. In addition to this, it may also elevate the chances of developing serious mental health conditions.

There are many studies that have shown a profound connection with gut health and its impact on brain functions, especially the areas responsible for learning, focus, and memory.

What are the Effective Ways to Improve the Gut Microbiome?

There are many ways that you can incorporate into your daily lifestyle to improve your gut health, which will, as a result, support overall good well-being:

Opting for a Wide Variety of Foods in your Routine:

Eating a diet rich in a variety of food items leads to a diverse microbiome, which is an indication of good gut health. The following items are packed with fiber: legumes, fruits, beans, etc., resulting in healthy Bifidobacteria.

Consuming Fermented Food Items:

There are many fermented food items, such as sauerkraut, yogurt, and kefir, that contain healthy bacteria majorly Lactobacilli. Consuming these food items can result in a decreased amount of disease-causing species in the gut. If you don’t eat such food items, try including them for good health.

Cut Back on Artificial Sweeteners:

Reducing the intake of artificial sweeteners can contribute to improved gut microbiota. It is believed that most artificial sweeteners result in increased blood sugar levels by encouraging the growth of unhealthy bacteria (Enterobacteriaceae) in the gut microbiome.

Include Prebiotic Food in Your Diet:

Consuming a diet rich in prebiotic food will stimulate the growth of healthy bacteria. The following are the common prebiotic-rich food items: bananas, oats, apples, artichokes, and asparagus.

Increase Whole Grains Intake:

Whole grains come with lots of fibers and healthy carbs such as beta-glucan. Gut bacteria digest these carbs and fibers and reduce your risk of cancer, diabetes, obesity, and other disorders.

Go for a Plant-based Diet:

Opting for a vegetarian diet can assist in reducing disease-causing bacteria, managing inflammation, and tackling bad cholesterol. In addition to this, a plant-based diet also minimizes your risk of developing several health conditions.

Take Antibiotics Only when Necessary:

Regular and unnecessary consumption of antibiotics can destroy many good bacteria while killing bad ones in the gut microbiome, resulting in weight gain and antibiotic resistance. Therefore, you should take antibiotics only when necessary and recommended by a healthcare professional.

The Bottom Line:

Your gut microbiome is the home to trillions of fungi, bacteria, and other microorganisms. The gut microbiome carries out several important roles in the body to keep various aspects of your health in check, especially mental health. Having an imbalance of healthy & unhealthy microbes in the intestines can result in cholesterol, weight, anxiety, depression, etc. In order to enable the healthy growth of microbes in your gut, consider eating a diet consisting of fruits, vegetables, whole grains, & fermented food items.

The link between gut health and mental health is clearer than ever. Taking care of your gut can support your mental and emotional well-being in order. If you have been feeling anxious or depressed lately and think that your gut could be part of the issue, consulting a doctor can really be helpful. By eating probiotic-rich food and maintaining the health of gut microbiota, you can improve your mental health. The gut-brain axis is crucial for mental health, highlighting the need for a complete wellness approach.

FAQs: 

1. Does good gut health improve mental health?

Yes, having good gut health definitely improves mental health. A balanced microbiome can lead to a positive mindset. On the other hand, if you are living with an imbalanced microbiome, you are more prone to come across issues related to mental health. 

2. What are the benefits of a healthy gut microbiome?

A healthy microbiome minimizes your risk of developing obesity, heart disease, cancer, and diabetes. If you get any signals from your gut, change your microbiome by altering your diet. You should avoid eating a high-fat diet and cut back on processed foods.

3. Can your gut biota determine your mood and mental health? 

Many studies have found that gut bacteria are responsible for producing neurotransmitters, including dopamine, serotonin, and gamma-aminobutyric acid. All of these neurotransmitters affect your mood, anxiety, and stress.

4. What are the positive effects of the gut microbiota?

The gut microbiota fosters a symbiotic relationship with the gut mucosa, providing significant metabolic, immunological, and protective functions in healthy individuals.
