bstract: The HJ-Biplot analysis is a multivariate graphic representation that collects data covariation structure between variables and individuals to represent them in a low-dimensional space in the same reference system with the highest quality. Consequently, it is a promissory technique to evaluate dietary exposure to polyphenols and to accurately characterize female nutrition. Herein, we hypothesized that polyphenol intake defines specific clusters with dietary impacts, which can be assessed by HJ-Biplot based on a cross-sectional study in Argentina. The sample involved 275 healthy postpartum women who answered about their food frequency intake and other conditionings, to then evaluate polyphenolic intake using the Phenol-Explorer database. Outcomes were established with HJ-Biplot for clustering and with ANOVA to compare their impact on diet quality indicators. Two HJ-Biplot models were run (for intakes >20 mg/d and 5-20 mg/d, respectively) to identify three clusters per model wit
