Gut-brain axis research links microbiota to Parkinson's and mental health

Research conducted at the University of Santiago de Compostela Faculty of Medicine has analyzed the relationship between Parkinson's disease and the intestinal bacterium Akkermansia muciniphila. After reviewing studies involving over 750 people, researchers confirmed consistent alterations in this bacteria, which is linked to the protective mucus layer of the intestine, among Parkinson's patients.

This connection highlights the importance of the gut-brain axis. Dietary habits play a crucial role in shaping the microbiota. For instance, foods rich in omega-3, such as sardines and mackerel, and various vegetables can support digestive and cognitive health.

Additionally, medical experts note that the gut acts as a ‘second brain’ due to the bidirectional connection between the digestive system and the brain. The intestinal microbiota is responsible for producing essential neurotransmitters and participating in 70% of the immune system. However, high levels of stress and anxiety can trigger a survival mode in the body, inhibiting digestive processes, gastric juices, and intestinal movements, which often leads to inflammation and heaviness.
