The Claim

Daily consumption of soy or lupin protein beverages for five weeks in adolescent boys with overweight or obesity is associated with increased gut microbiota diversity and higher abundance of Bacillota and butyryl-CoA transferase-positive bacteria.

In plain English

In adolescent boys with overweight or obesity, drinking soy or lupin protein beverages daily for five weeks is linked to greater diversity in gut bacteria and higher levels of Bacillota and bacteria that produce butyryl-CoA transferase.

See the scientific wording

Daily consumption of soy or lupin protein beverages for five weeks in adolescent boys with overweight or obesity is associated with increased gut microbiota diversity and higher abundance of Bacillota and butyryl-CoA transferase-positive bacteria, suggesting a potential prebiotic effect on microbial composition.

Why this might work

When adolescent boys drink soy or lupin protein shakes daily, the proteins and fibers in them feed specific gut bacteria that make butyrate, a healthy fat. These bacteria grow in number and strengthen the gut lining, preventing harmful substances from leaking into the blood. This stops chronic inflammation in fat tissue, which allows the body to use insulin more effectively and lowers blood sugar.

    The study found that overweight teen boys who drank soy or lupin protein shakes every day for five weeks ended up with more types of good gut bacteria, especially ones that help make healthy fats for the body — just like the claim said.
