The Latvian Microbiome Project is a citizen science initiative aimed at establishing an overview of the microbiome of the Latvian population and how diet and lifestyle affect it. Launched in 2019, the project has so far involved 1000 voluntary participants and is almost ready for applying artificial intelligence (AI) tools to analyze the collected biospecimens and qualitative data. Participants will soon have access to Gut IT – a dedicated “health portal”, which will be updated as the pool of data grows.
