The Claim
In middle-aged women with metabolic syndrome risk factors, low resistant starch intake is associated with increased abundance of the gut bacterial genus Marvinbryantia, which is associated with higher butyrate production and stable lipid metabolism, whereas high resistant starch intake is associated with increased abundance of Veillonella and elevated triglyceride levels.
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 middle-aged women with metabolic syndrome risk factors, eating less resistant starch is linked to higher levels of the gut bacteria Marvinbryantia, which correlates with stable lipid levels and more butyrate, while eating more resistant starch is linked to higher levels of Veillonella and increased triglycerides.
See the scientific wording
In middle-aged women with metabolic syndrome risk factors, low resistant starch intake is associated with an increase in the gut bacterial genus Marvinbryantia, which is linked to butyrate production and stable lipid metabolism, contrasting with the triglyceride rise seen with high resistant starch and Veillonella enrichment.
When people eat less resistant starch, a gut bacterium called Marvinbryantia grows and makes butyrate, which tells the liver to stop making fat and start burning it instead. When people eat more resistant starch, a different gut bacterium called Veillonella grows and makes acetate and propionate, which tell the liver to make more fat, raising triglyceride levels in the blood.
What the research says
1 studyIn women with metabolic risks, eating less resistant starch raised a good gut bacteria called Marvinbryantia, which helps keep fat levels stable, while eating more resistant starch raised a different bacteria linked to higher triglycerides — just like the claim says.
