It was our pleasure to host the second major international meeting of the International Society for Nutritional Psychiatry Research, which was held in London, United Kingdom, between the 20th to 22nd of October 2019 at the The Park Plaza London Riverbank on the banks of the Thames River.

This meeting built upon the initial 2017 conference and reflected the broad and evolving spectrum of Nutritional Psychiatry research, from the sub-cellular to translation and implementation science. The program emphasized the international growth of the field, and catered to the interests of researchers and clinicians from the fields of psychiatry and psychology, as well as public health, diabetes, cardiovascular disease, obesity, dietetics and integrative medicine. There was a strong focus on basic science and the biological processes and factors that underpinned the links between diet, nutrition and mental health, including the gut-brain axis, immunological and metabolic processes, and molecular science. This meeting also focused on translation and public health applications of Nutritional Psychiatry, with a focus on building capacity across clinical, research, and public domains.
