Key Highlights
- The 90% of the serotonin circulating in our body is produced by intestinal neurons.
- The gut and its bacterial inhabitants influence the production of essential molecules to regulate mood and happiness.
- Bacteria in the intestine can affect the synthesis of neurotransmitters like serotonin, dopamine, and GABA.
- Equilibrium in the microbiota generates “good” molecules such as short-chain fatty acids, neurotransmitters, and neuroactive peptides that benefit the organism.
The Gut-Brain Connection: Serotonin Production in Intestinal Neurons
Dr. María Dolores de la Puerta, an expert in microbiota and digestive health, has highlighted how the gut and its bacterial inhabitants play a crucial role in producing neurotransmitters like serotonin, dopamine, and GABA. These molecules are essential for regulating mood, calmness, and happiness.
The Importance of Serotonin Production by Intestinal Neurons
According to Dr. de la Puerta, the 90% of the serotonin circulating in our body is produced by intestinal neurons, while only 10% is found in the head. This significant proportion underscores the profound connection between the digestive system and emotional well-being.
The Role of the Microbiota in Neurotransmitter Production
Dr. de la Puerta explains that these molecules are not solely produced in the brain but also by neurons in the gut. The intestinal neurons form part of the enteric nervous system, which maintains constant dialogue with the intestinal microbiota. This interaction allows beneficial bacteria to influence neurotransmitter synthesis and emotional stability.
Factors Influencing Neurotransmitter Production
Dr. de la Puerta notes that factors such as meditation or positive social environments can enhance the release of these molecules, but maintaining a healthy gut microbiota is crucial for ensuring their correct production even in the absence of external stimuli. The doctor emphasizes that although serotonin from the intestine does not cross the blood-brain barrier, it communicates with the brain through the vagus nerve.
The Impact of Gut Health on Mental Well-being
Dr. de la Puerta’s work focuses on demonstrating how a balanced gut not only facilitates digestion but also impacts emotional and mental health. She stresses that the microbiota is one of the organs with the greatest capacity to interact with other body systems, contributing to normal functioning across all bodily systems.
Conclusion
The Importance of Gut Health for Overall Well-being
The research underscores the importance of gut health in maintaining overall well-being. Maintaining a healthy microbiota through diet and lifestyle choices can ensure the production of beneficial molecules such as short-chain fatty acids, neurotransmitters, and neuroactive peptides that support both physical and mental health.
