Due to their polyphenolic content, vegetable foods have neuroprotective effects which provide health benefits for specific human groups. Thus, they may be a useful dietary component for women who experience mnesic variations during postpartum, and here we examined the hypothesis that polyphenols can differentially enhance memory functioning. In particular, we aimed to associate the dietary intake of polyphenols with different memory systems in Argentinian postpartum women. The daily intakes of polyphenol groups were calculated using a validated food frequency questionnaire and the Phenol-Explorer database. Short-term memory (STM), long-term memory (LTM), learning (L), lexical-semantic memory (LSM), and working memory (WM) were assessed. Partial Least Squares (PLS) regression models were used to analyze the dietary polyphenols (predictors) and memory domains (responses), taking into account demographic, obstetric, and psychological factors. The sample included 71 women, with an average age of 29.59 years (SE = 0.73). Most of these women lived in a couple (91%), were unemployed (63%), and had ≥12 years of formal education (72%). STM, LTM, L, and LSM correlated with lignans and anthocyanins, with LTM also being correlated with flavanones, flavonols, and tyrosols, and L and LSM also being associated with flavonols. A significant correlation was also found between WM and lignans. In conclusion, a cognitive improvement was demonstrated, mainly associated with the intake of lignans and anthocyanins, in the STM, LTM, WM, L, and LSM systems of postpartum women. This is the first study to our knowledge suggesting a role of polyphenolic effects on memory functioning during postpartum.

通过膳食摄入木酚素和花青素可增强阿根廷妇女产后记忆力
由于其多酚含量，蔬菜食品具有神经保护作用，可为特定人群提供健康益处。因此，对于在产后经历记忆力变化的女性来说，它们可能是一种有用的饮食成分，在这里我们检验了多酚可以不同地增强记忆功能的假设。特别是，我们旨在将多酚的膳食摄入量与阿根廷产后妇女的不同记忆系统联系起来。使用经过验证的食物频率问卷和 Phenol-Explorer 数据库计算多酚组的每日摄入量。评估了短期记忆 (STM)、长期记忆 (LTM)、学习 (L)、词汇语义记忆 (LSM) 和工作记忆 (WM)。偏最小二乘 (PLS) 回归模型用于分析饮食多酚（预测因子）和记忆域（响应），同时考虑人口统计学、产科和心理因素。样本包括 71 名女性，平均年龄为 29.59 岁（SE = 0.73）。这些女性中的大多数 (91%) 生活在一对夫妇中，失业 (63%)，并且受过 12 年以上的正规教育 (72%)。STM、LTM、L 和 LSM 与木脂素和花青素相关，LTM 还与黄烷酮、黄酮醇和酪醇相关，L 和 LSM 也与黄酮醇相关。在 WM 和木脂素之间也发现了显着的相关性。总之，在产后妇女的 STM、LTM、WM、L 和 LSM 系统中，证明了认知改善，主要与木脂素和花青素的摄入有关。
