University of Southampton researchers use the Blue Poo Test to study the gut-brain connection
Overview
Scientists at the University of Southampton are asking thousands of participants across the UK to take part in the Blue Poo Test. The study involves tracking how long it takes for blue-coloured muffins to digest, followed by online brain games, to understand how gut transit speed correlates with cognitive performance across different age groups and demographics.
Key points
- Researchers at the University of Southampton are leading a project called the Blue Poo Test.
- Participants track the digestion speed of muffins made with edible blue food colouring.
- After noticing blue waste, participants complete online brain games to test problem-solving and decision-making skills.
- The study aims to determine how gut transit times relate to brain performance across various demographics.
- The project is open to participants ranging from five to nearly 100 years old, with results expected next year.
