The Claim

A plasma metabolite profile characterized by reduced cortisol and specific phospholipids and increased N-acetylornithine and homoarginine is inversely associated with a 25% lower incidence of type 2 diabetes over a median follow-up of 3.7 years in elderly Mediterranean adults at high cardiovascular risk, independent of self-reported legume intake and other dietary and lifestyle factors.

In plain English

In elderly Mediterranean adults at high cardiovascular risk, a specific pattern of blood metabolites—including lower cortisol and certain phospholipids and higher N-acetylornithine and homoarginine—is linked to a 25% lower rate of type 2 diabetes over 3.7 years, regardless of reported legume consumption or other lifestyle factors.

See the scientific wording

A plasma metabolite profile associated with legume consumption, including reduced levels of cortisol and specific phospholipids and increased levels of N-acetylornithine and homoarginine, is inversely associated with a 25% lower incidence of type 2 diabetes over a median follow-up of 3.7 years in elderly Mediterranean adults at high cardiovascular risk, independent of self-reported legume intake and other dietary and lifestyle factors.

Why this might work

Eating legumes increases certain amino acid byproducts in the blood that improve how the body uses insulin and lowers stress hormones. These changes reduce sugar production in the liver and make muscle and fat cells more responsive to insulin, which prevents blood sugar from rising too high and stops diabetes from developing.

    Scientists found that people with certain blood chemicals linked to eating beans had a 25% lower chance of getting type 2 diabetes over a few years — even if they didn’t say they ate many beans. This suggests those chemicals might be a hidden sign of bean benefits.
