Abstract: |
At the present time, achieving mental health is not only a fundamental foundation for individual and social well-being, but is also considered a vital prerequisite for intellectual flourishing, enhanced quality of life, and professional success. The human ability to handle stress, adapt to environmental changes, maintain stable social relationships, and utilize cognitive capacities is strongly influenced by mental well-being. The human gut hosts trillions of microorganisms that communicate bidirectionally with the brain through neural, immune, endocrine, and metabolic pathways. The role of biological compounds secreted by gut bacteria, including neurotransmitters such as serotonin and gamma-aminobutyric acid (GABA), hormones, and short-chain fatty acids, in regulating mood, stress response, and cognitive functions has received increasing attention. Therefore, the concept of "psychobiotics" as a new generation of probiotics can exert positive influences on the gut-brain axis, leading to prevention or treatment of disorders like anxiety, depression, and cognitive decline. Functional foods like dairy products, by fortifying the beneficial gut microbiota and increasing the production of beneficial metabolites, offers a novel tool for improving mental and physical health. Consequently, integrating knowledge from nutritional sciences, neuroscience, and microbiology related to psychobiotics can open a new path for designing targeted nutritional strategies to promote mental health.
