Breath tester (Food Marble device)
What this could lead to
If successful, this could provide a simple, non-invasive way to track fiber intake without relying on self-reporting.
What could go wrong
This is a very small pilot study (30 people) and only tests correlation, not cause. The device may not accurately reflect fiber intake in real-world settings.
