First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether eating three apples daily for three days changes the activity of gut bacteria in healthy adults.

Scientists analyzed the samples to see if short-term fruit fiber intake leads to measurable shifts in gut metabolism.
