Brief summary: The link between what people eat and how it affects faecal output (poo) has been understudied. Most of the research that has looked at the link between diet, bowel movements and overall health has studied different types of fibre extracted from foods (e.g., fibre extracted from carrots), rather than foods in the form that they are consumed.

It is necessary for scientists to investigate the relationship between food as people usual eat it (e.g., a carrot) and bowel movements, as this information is key to understanding the relationship between what people eat and overall health.

The investigators would like to understand the relationship between intake of certain foods and faecal output. This will help to develop a chart, similar to the United Kingdom National Health Service urine colour hydration chart. The chart will allow people to know, by looking at their poo, whether they are eating enough of the foods that will keep them healthy. By monitoring and measuring participants' bowel movements, and providing information about diet, participants will provide the data we need for this research.

Detailed description: Participants will complete a 5-day estimated food record and weigh, characterise and photograph each stool for 5 days.

* Currently engaging in intense physical activity more than 3 times per week (assessed on an individual basis).
* Presenting a psychological or linguistic incapability to sign the informed consent/ Investigator considers the subject unlikely to comply with study procedures, restrictions, and requirements.
* Parallel participation in another research project which involves dietary intervention/other clinical trial.
