The gut-brain axis (GBA) consists of bidirectional communication between the central and the enteric nervous system, linking emotional and cognitive centers of the brain with peripheral intestinal functions. In clinical practice, evidence of microbiota-GBA interactions comes from the association of dysbiosis with central nervous disorders (i.e. autism, anxiety-depressive behaviors) and functional gastrointestinal disorders.

With strong evidence suggesting that gut microbiota has an important role in bidirectional interactions between the gut and the nervous system, it interacts with CNS by regulating brain chemistry and influencing neuro-endocrine systems associated with stress response, anxiety and memory function.
Many of these effects appear to be strain-specific, suggesting a potential role of certain probiotic strains as novel adjuvant strategy for neurologic disorders. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4367209/
The gut and the brain are very connected, which is why the gut is often referred to as the “second brain”. Bacteria in the gut act on the central nervous system, which allows for constant communication between the gut and the brain (via this gut-brain axis).
Many children with ASD have a “leaky gut”, which means their intestinal tract allows toxins and bacteria into the bloodstream instead of keeping them sealed within the walls of the intestines. This can cause problems with brain function, moreover, bacterial imbalances in the gut can also alter other compounds in the body, such as amino acids and fatty acids, which impact the brain and behavior.
The brain and gut also communicate through the immune system, and some people with ASD have a bacterial imbalance that activates the immune system and causes inflammation throughout the body and brain.
Extra Virgin Olive Oil & Gut-Brain Axis
Extra-virgin olive oil and the gut-brain axis: influence on gut microbiota, mucosal immunity, and cardiometabolic and cognitive health.
Extra-virgin olive oil (EVOO), possesses a variety of healthful components, including monounsaturated fatty acids and bioactive phenolic compounds that, individually and collectively, exert beneficial effects on cardiometabolic markers of health and act as neuroprotective agents through their anti-inflammatory and antioxidant activities.
The gut microbiota and health of the intestinal environment are now considered important factors in the development of obesity, metabolic disease, and even certain neurodegenerative conditions via the gut-brain axis.
Consumption of EVOO clearly demonstrates widespread beneficial effects on a variety of aspects of health and disease and also shows great therapeutic potential in positively modifying the gut microbiota as well as the activity and functioning of the mucosal immune system. https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuaa148/6133931
