Abstract

, respectively). Genistein and daidzein levels were strongly correlated with their intake values (rho ∼ 0.6), as well as with legumes and soy-rich foods. A cluster driven by urinary isoflavonoids was identified. Both dietary and urinary (poly)phenols predominated in PBDs. Genistein and daidzein represent stable biomarkers of legume and soy intake and are key indicators of plant-based dietary patterns.
