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.
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 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.
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.
What the research says
1 studyThe study gave overweight teenage boys daily drinks with soy or lupin protein for five weeks and found they grew more good gut bacteria that help with metabolism — exactly what the claim said would happen.
