The Claim

In middle-aged women with metabolic syndrome risk factors, high resistant starch intake for 8 weeks is associated with a significant increase in the gut bacterial genus Veillonella, and this increase is linked to elevated triglycerides and adiposity through enhanced production of acetate and propionate that stimulate hepatic lipogenesis.

How it works
1 study reviewed
In plain English

In middle-aged women with metabolic syndrome risk factors, consuming high amounts of resistant starch for 8 weeks is associated with higher levels of the gut bacterium Veillonella, which is linked to increased triglycerides and body fat due to greater production of acetate and propionate that promote fat synthesis in the liver.

See the scientific wording

In middle-aged women with metabolic syndrome risk factors, high resistant starch intake for 8 weeks is associated with a significant increase in the gut bacterial genus Veillonella, which may contribute to elevated triglycerides and adiposity through enhanced production of acetate and propionate that stimulate hepatic lipogenesis.

Why this might work

When resistant starch reaches the gut, it feeds a type of bacteria called Veillonella. This bacteria turns lactate into two chemicals, acetate and propionate, which travel to the liver. In the liver, these chemicals turn on a switch that makes more fat, leading to higher fat levels in the blood and more fat stored in the body.

    In women with metabolic risks, eating more resistant starch for 8 weeks increased a gut bacteria called Veillonella and also made their blood fats and body weight go up—exactly what the claim said might happen.
