Eat Well

Research is helping us understand our gut health is key to both physical and mental wellbeing. A study called the SMILES trial was the first to show that improving nutrition could reduce depressive symptoms.

Starting Point

Nutrition is often thought of in terms of our physical health. But the impact of food on our bodies is so much more than physical. Did you know some foods actually help us regenerate brain cells, whilst others can destroy them?

If thinking about what you eat feels overwhelming, you are not alone. We will learn here about the evidence linking food and mood and see how understanding the gut-brain connection can help us eat well. But the most important place to start? Be kind to yourself. This is not about judgement or labelling certain foods or eating behaviours as good or bad.

Proof

The exciting new field of nutritional psychiatry is taking our understanding of food and its impact on our body to a whole other level. Our mood is inextricably linked to our food – which means there is lots we can do to take care of body and mind by understanding this a little more.

Our guts (enteric nervous system) and our brains (central nervous system) communicate via the “gut-brain axis”. These messages are influenced by body processes like inflammation, oxidative stress and our gut-microbiota (the millions of bugs in our guts). Which means what we eat impacts our mental health.

The SMILES Trial

Professor Felice Jacka talks to Rangan Chatterjee about her groundbreaking research, the SMILES trial. The study showed – for the first time – the effect of diet on depression.

You can find out more about the SMILES trial from the Food and Mood Centre here.

The Gut Microbiome

What do we mean by the gut microbiome? This video gives you a quick introduction.

Fibre & Fermented Foods

This TED-Ed talk introduces why fibre and fermented foods are important for our microbiome.

Ongoing research (eg this 2021 paper) is teaching us how fibre and fermented foods  increase microbiome diversity and decrease markers of inflammation – all of which benefits our mental health.
