Diet is a health foundation to support breastfeeding and enable lactating women’s recovery. This study aimed to develop three valid diet adherence indices by a clinimetric contrast with different parameters. We hypothesize that the three diet adherence-based indices are positively correlated with diet quality and milk biomarkers, and directly related to calcium, fiber, and energy intake. A cross-sectional study recorded food frequency, anthropometric and dietary measures, and milk analysis to estimate correlations, sensitivity, and specificity (n=284). Three reliable indices agreed by >75% with food frequency: Macronutritional (MDI), Phytochemical (PDI), and Energetic (EDI), which correlated positively to the Fat Quality Index and Minimum Dietary Diversity for Women. MDI and EDI correlated negatively to the Healthy Plant-Based Diet Index (H-PBDI), whereas PDI did it positively. MDI correlated positively to the Protein-to-Carbohydrate Ratio (PCT), whereas EDI did it negatively. Inadequate intakes of calcium, fiber, and energy were indicated by MDI
