Two-way communication between the gut and the brain


There is a real two-way communication between gut and brain. It’s not by chance that emotional and mental stress is one of the main causes of gut permeability, dysbiosis, bloating and colitis.

Vice versa, an irritated gut or damaged microbiome can alter mood, emotions, stress responses, favouring anxiety, depression or dysfunctional behaviour.

Gut bacteria constantly dialogue with the brain via the gut-brain-microbiome axis and produce substances and neurotransmitters that regulate optimal functioning of neurons and order emotional response.

What we eat each day can positively or negatively influence bacterial composition and plays a critical role in gut permeability in inflammatory response.

For these reasons, throughout the course we’ll look at: what to eat, which foods to avoid, key probiotics, targeted supplements and practical suggestions to rebalance the gut, restore gut bacterial flora and thus improve anxiety, stress, depression and emotional response.

Foods that are good for the microbiome

Discover which foods help reduce inflammation and restore gut bacterial flor

Probiotics and prebiotics

Gut, mood and emotion

Discover how intestinal health influences thoughts, emotions, mood and behaviour - and vice versa

Jo Ferrari

"I’ve always had stomach problems, but I had never associated them with my anxiety and panic attacks. I’ve finally rebalanced my bacterial flora and drastically reduced anxiety and stress."

Eric Martin

"Truly useful advice for the people that I work with every day and have difficulties in the management of emotions."

“Microbes and nervous cells within the gut constantly communicate with each other and with the brain via the gut-brain-microbiome axis.

At the centre of this axis, you will find the vagus nerve that is key to emotional and interpersonal regulation. Direct intervention at this level- via the right diet- enables rapid, effective change for both physical health and mental and emotional change.”

Sara has a Degree in Nutrition Sciences and is a Nutrition and Health expert that focuses on the ways that foodnutrition and physical activity affect our healthemotional responsesmood and cognitive abilities. She is co-founder of the Association for Integrative Sciences and of the Real Way of Life research and training centres where she works as a consultant, researcher and trainer. 

She developed the Emotional-Metabolic Switch model to intervene on inflammatory conditions of the gutbrain and, at the same time, on energy metabolism and the efficiency of mind-body interaction.

Her work slots into the Change Switches theory starting from initial cell responses (metabolic energy, epigenetic marking, inflammatory cascade) and is applied right throughout, across various levels of complexity that influence initial adaptation responses (from hunger to a sense of void), to brain networks at the heart of emotions and self-image (both physical and relating to identity), to self-regulation and primary interpersonal relation models (tolerance towards waiting, nurture, sharing etc.).

Sara researches and evaluates the reciprocal influence between nutritioncell responses, epigenetics, responses to pain, management of emotions and behaviour.

Sara coordinates nutrition and wellbeing projects both at individual clinical level and in their overall social implication aspects, presenting her findings each year to an international audience.
