I'm interested in getting personal health data from unusual sources. What are some surprising things you can learn from your stool/fecal material, e.g. regarding:
- Gut flora
- Digestive health
- Metabolic health [from break down waste products]
- From trace amounts of DNA
Yes, obviously stool may not be as informative as other health related tests, e.g. blood tests, so would not be the most direct way to assess certain things. However, it is still a non-invasive and potentially useful additional source of data about your own body, so please only provide serious answers.
