How Does the Microbiota Influence Our Mental Well-being? The Science of the Gut-brain Axis

In the complex tissue that makes up our mental health, the intestinal microbiota emerges as a crucial protagonist, playing a significant role In the last decade, the interaction between the intestinal microbiota and emotional well-being has been the subject of attention and research. This comprehensive approach has shed light on the close relationship between what we eat, how we enjoy it and how it impacts our mental health.

Meals have always served as a social bond, a time to share and connect with our loved ones. However, beyond its social function, every bite we consume triggers a complex series of biochemical events that influence our mood and emotional well-being. As we explore the profound link between gut microbiota and mental health, a revelation emerges – it’s not just what we eat that matters, but also how we enjoy it and who we share it with.

This article attempts to value the importance of caring for the microbiota in terms of its relationship with mental health, highlighting the need to enjoy meals in company and the vital importance of this combination to nourish both our body and our mind. Highlight awareness of how each food choice and each moment shared around the table can contribute to our emotional and psychological well-being.

What is the microbiota?

The microbiota, also known as microbial flora or microbiome, refers to the community of microorganisms that live in a specific environment, such as the human body, soil, water or air. Specifically in humans, the microbiota refers to the population of microorganisms that inhabit various parts of the body, especially the skin and the gastrointestinal tract.

In the human intestine the microbiota is mainly composed of bacteria, but also includes viruses, fungi and other microorganisms. These intestinal bacteria play a fundamental role in digestive, metabolic and immunological functions. They aid in the digestion of food, synthesize vitamins, protect against harmful pathogens, regulate the immune system, and may even influence mental health and behavior.

The composition of the intestinal microbiota can vary significantly from one person to another, because it is influenced by factors such as genetics, diet or lifestyle The imbalance of the microbiota is known as dysbiosis. When this happens, there may be a decrease in the diversity of beneficial bacterial species and an increase in the prevalence of potentially harmful bacteria.

This can be associated with various health problems, including gastrointestinal disorders such as irritable bowel syndrome, inflammatory diseases, allergies, obesity, diabetes, autoimmune diseases and psychiatric disorders such as anxiety and depression, even with degenerative diseases such as Alzheimer’s or Parkinson’s.

Interest in studying the relationship between the microbiota and mental health has arisen for several reasons. There is a significant relationship called the gut-brain axis, which is a bidirectional communication between such organs. This connection is made through nervous, hormonal and immunological pathways. The indication to eat certain foods allows you to modify the composition of the intestinal microbiota and thus have beneficial effects on behavior and brain function The administration of probiotics can improve it, but prolonged intake of antibiotics, for example, has been shown to negatively influence anxiety, depression and cognition.

The gut-brain axis: how are they related?

Emeran Mayer, a neuroscientist and gastroenterologist recognized worldwide for his book The Mind-Gut Connection, has conducted research on the gut-brain axis and the interaction between the gut microbiota and mental health.

Serotonin is a neurotransmitter that plays a critical role in regulating mood, sleep, appetite, and various physiological functions in the human body. Although most serotonin is produced in the brain, it is estimated that about 90% of the total serotonin in the human body is found in the gastrointestinal tract mainly in the small intestine.

Serotonin-producing cells, called enterochromaffin cells, are found in the mucosa of the small intestine. These cells produce and release serotonin in response to stimuli, such as food intake. The vital moments where this axis can be altered is fundamentally at the beginning and end of life, that is, when neurodegenerative diseases occur, such as Alzheimer’s or Parkinson’s, since changes in the microbiota and in the intestine begin before they begin. neurological symptoms in both diseases, or during the first months or years of life, when the brain is developing.

So the recommendations while research on the subject continues indicate that taking care of mental health also means taking care of the way we eat and what we eat. The old Mediterranean diet of vegetables and fruits seems to continue to be the most appropriate option for the health of our gut-brain axis

Practicing meditation, mindfulness, yoga or some stress reduction technique will help us understand ourselves in a more integrative way and increasingly see ourselves as a unit, which is what we really are. The feedback between stress, microbiota and mental health is not in dispute. So, let’s start the change where it is easiest for us, it may be with food or managing stress or anxiety, the important thing is to know that this change will have a positive impact on our entire being.

This awareness should also extend to health professionals in general, since with the welcome specifications achieved due to technological advances, a body has been dissected into so many parts that patients themselves complain about this reification, unaware that behind each study or every practice you find a human with feelings, fears, anxieties that seem to be not taken into account. The idea is not to lose sight of the fact that we are beings full of emotions and that the way we are treated in relation to them, the better we will react to the treatments that are indicated to us

In those cases in which the symptoms exceed a reasonable state of discomfort or permanence over time, it is necessary to recommend CBT, cognitive behavioral psychological therapy, to the patient since this type of technique is the one with which the greatest effectiveness has been proven when it comes to attack symptoms and correct unhealthy habits.

Supervision is necessary with a mental health professional trained in consultation or adapted to working as a team, who can indicate changes in the direction of treatment, variations in treatment, or medical consultations if necessary. That is, a professional who remains attentive to physiological changes or dysfunctions, trained in the integration not only of the psychological alteration, in this way the improvement will be noticeable

Neglecting these aspects causes some people to fall into a vicious cycle in which stress and anxiety can exacerbate physical symptoms and vice versa. Coping with anxiety can be challenging and often requires lifestyle modifications. There are no dietary changes that can cure anxiety, but paying attention to what you eat, how you eat it and with whom, can help a lot to balance our entire being.

Trying to eat healthy foods is important for physical and mental health. Changes in diet can make a difference in general mood or sense of well-being, but they are not a substitute for both medical and psychological treatment Lifestyle changes such as improving sleep habits, increasing social support, using stress-reduction techniques, and getting regular physical activity can also help.

In conclusion, research on the gut microbiota has revealed its crucial role in mental health and emotional well-being Microbiota composition and diversity are closely linked to mood, anxiety and depression, with emerging evidence suggesting that a healthy gut microbiome may promote better mental health.

We must not forget that we are community beings and that effective and affective social relationships, as well as positive social interaction, can influence the composition of the microbiota, creating a feedback cycle between emotional well-being and intestinal health. These findings underscore the importance of nurturing both our social relationships and our gut health to promote optimal mind-body balance.

Give attention to the body, to nourish it adequately, cultivate a healthy intestinal microbiota without ceasing to attend to our psyche and our spirit fostering positive social relationships, and bringing food together can be complementary strategies to improve mental health and emotional well-being in modern society.

Without a doubt, paying attention to the body and nourishing it properly is essential to cultivating a healthy intestinal microbiota. But we cannot forget that our mental and emotional well-being also requires attention. Taking care of our intestinal microbiota and eating consciously not only benefits our body, but also our mind. Research shows how a balanced and varied diet can influence our mood and emotional health. Additionally, social support and meaningful relationships provide a sense of belonging, emotional support, and stress reduction, all of which positively impact our mental health.

Therefore, by placing emphasis on caring for both our body and mind, as well as strengthening our social relationships, we are embracing a comprehensive approach to well-being By being aware of the close relationship between these aspects of our existence, we can develop a more enriching and rewarding life. Ultimately, achieving a balance between physical care, mental health and positive social connections is essential to raising our quality of life in the contemporary world.
