The Claim
Moderate red wine consumption (250 mL/day for 4 weeks) in healthy adults is associated with increased fecal concentrations of short-chain fatty acids (SCFAs), including butyrate, propionate, and acetate, with significant positive correlations among these metabolites observed in wine consumers but not in control groups.
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.
Healthy adults who drank 250 mL of red wine daily for four weeks had higher levels of butyrate, propionate, and acetate in their feces compared to those who did not drink wine, and these three compounds were positively correlated in wine drinkers but not in non-drinkers.

Moderate red wine consumption (250 mL/day for 4 weeks) in healthy adults is associated with increased fecal concentrations of short-chain fatty acids (SCFAs), particularly butyrate, propionate, and acetate, with significant positive correlations observed between these metabolites in wine consumers but not controls.
Red wine polyphenols reach the colon and are broken down by specific gut bacteria, which then work together to produce more short-chain fatty acids like butyrate, propionate, and acetate. These bacteria become more abundant and their activities become more coordinated, leading to higher and more tightly linked levels of these fatty acids in the gut.
What the research says
1 studyDrinking a glass of red wine every day for a month helped increase good gut fats called SCFAs, and these fats tended to go up together only in people who drank wine — not in those who didn’t.
