The Claim

Daily consumption of soy or lupin protein for five weeks increases gut microbiome diversity and the abundance of Bacillota and butyryl-CoA transferase-positive bacteria in adolescent boys with overweight or obesity.

Cause and effect
1 study reviewed
In plain English

In adolescent boys with overweight or obesity, consuming soy or lupin protein every day for five weeks leads to higher gut microbiome diversity and increased levels of Bacillota and butyryl-CoA transferase-positive bacteria.

See the scientific wording

Daily consumption of soy or lupin protein for five weeks increases gut microbiome diversity and abundance of Bacillota and butyryl-CoA transferase-positive bacteria in adolescent boys with overweight or obesity, suggesting a shift toward a metabolically favorable microbial profile.

Why this might work

When adolescent boys with overweight or obesity eat soy or lupin protein daily, gut bacteria break down the protein and fiber to make butyrate, a molecule that fixes the gut lining. This stops harmful bacterial toxins from leaking into the blood, which lowers inflammation in fat tissue. Less inflammation lets the body respond better to insulin, lowering blood sugar and insulin levels.
