The Claim

In mice with loperamide-induced constipation, a 4-week dietary intervention with Shatianyu fruit powder increases fecal butyrate levels and colonic FFAR3 expression in a dose-dependent manner, enhances serotonin secretion through upregulation of Tph1 in enterochromaffin cells, and reduces colonic expression of TLR-4, TNF-α, and IL-1β, indicating an association between dietary fiber and flavonoid-rich fruit intake and improved intestinal motility and barrier function in this model.

How it works
1 study reviewed
In plain English

In mice with constipation caused by loperamide, consuming Shatianyu fruit powder for four weeks increases butyrate in the feces, raises FFAR3 and serotonin levels in the colon, and lowers inflammatory markers TLR-4, TNF-α, and IL-1β, which correlates with improved intestinal movement and barrier integrity.

See the scientific wording

In mice with loperamide-induced constipation, a 4-week dietary intervention with Shatianyu fruit powder increased fecal butyrate levels and colonic FFAR3 expression in a dose-dependent manner, while simultaneously enhancing serotonin secretion through upregulation of Tph1 in enterochromaffin cells and reducing colonic inflammation markers (TLR-4, TNF-α, IL-1β), suggesting an association between dietary fiber and flavonoid-rich fruit intake and improved intestinal motility and barrier function in this model.

Why this might work

Eating Shatianyu fruit powder feeds good bacteria in the gut that make butyrate. Butyrate turns on a receptor called FFAR3 in gut cells that produce serotonin, causing more serotonin to be made and released. At the same time, butyrate blocks inflammation signals in the colon, reducing harmful chemicals and strengthening the gut lining.

  1. Study: Shatianyu (Citrus grandis L. Osbeck) whole fruit alleviated loperamide-induced constipation via enhancing gut microbiota-mediated intestinal serotonin secretion and mucosal barrier homeostasis.

    Feeding constipated mice powdered Shatianyu fruit helped their guts move better by boosting helpful bacteria that make butyrate, increasing a mood-related chemical called serotonin, and calming down gut inflammation.
