(Poly)phenol profiles of plant-based diets assessed through dietary intake and urinary biomarkers

ECE. Casas-AlbertosNRN. M. Rodriguez-MartínAAA. Alcalá-Santiago

Key Points

  • This research aims to evaluate the profiles of (poly)phenols in plant-based diets through dietary intake and urinary biomarkers.
  • Analysis of dietary intake values of polyphenols, specifically focusing on genistein and daidzein.
  • Assessment of urinary biomarkers to correlate with dietary consumption of legumes and soy-rich foods.
  • Identification of clusters driven by urinary isoflavonoids.
  • Genistein and daidzein levels showed a strong correlation with intake values (rho ∼ 0.6).
  • Both dietary and urinary (poly)phenols predominated in plant-based diets.
  • Genistein and daidzein served as stable biomarkers indicating legume and soy intake.

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.
