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.

How it works
1 study reviewed
In plain English

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

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 potential mechanism for metabolic improvement through microbial modulation.

Why this might work

When soy or lupin protein is eaten, gut bacteria break them down and make more butyrate, a molecule that tightens the gut lining. This prevents harmful bacterial parts from leaking into the blood, which lowers inflammation in fat tissue. With less inflammation, the body's cells respond better to insulin, lowering blood sugar and insulin levels.
