The Claim
Higher dietary fiber intake from fruits (excluding berries) in healthy U.S. adults is associated with increased relative abundance of the bacterial genus Lachnospira.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy adults in the U.S., consuming more dietary fiber from fruits (not including berries) is linked to higher levels of the gut bacteria Lachnospira.
See the scientific wording
In healthy U.S. adults, higher dietary fiber intake from fruits (excluding berries) is associated with increased relative abundance of the bacterial genus Lachnospira, a pectinolytic taxon, suggesting a specific link between fruit-derived fiber and gut microbial composition.
When people eat fruits like apples and citrus, the fiber called pectin passes through the stomach and small intestine without being broken down. In the colon, bacteria that can break down pectin, like Lachnospira, use special enzymes to chop it into smaller pieces and turn those pieces into energy. This gives Lachnospira a growth advantage over other bacteria, so it becomes more common in the gut.
What the research says
1 studyPeople who ate more fruit (not berries) had more of a gut bacteria called Lachnospira, which eats the kind of fiber found in fruit. The study found this link clearly and reliably.
