There is now over-whelming evidence to support the fact that gut microbes (collectively called the microbiota) have a major impact on our brains and our behaviour, especially in stress related disorders such as anxiety.
In this helpful booklet the various components of a healthy diet in relation to stress are examined. Overall it seems reasonable to conclude that those living with anxiety should be encouraged to enhance a plant-based diet with a high content of grains /fibres and fish. Such a diet will promote the development of an optimal microbiota and hopefully better mental health.
