A significant body of evidence suggests that poor dietary intake is associated with reduced cognitive function. However, few studies have examined this relation in poor urban settings. Our brief review suggests that (a) higher overall diet quality may play a particularly important role in cognitive function among the poorest; and (b) greater vitamin E intake is related to better cognitive performance, at least in part, via fewer depressive symptoms. The broader recent literature strongly suggests the beneficial role of diet for learning and memory, and potentially synergistic influences on other cognitive domains. However, adherence to healthful diet among urban poor may be limited by factors such as cost and access. Here, we propose several potential moderators and mediators of diet-cognition relations among urban poor. Future studies should focus on the complex interplay among factors that influence the role of diet in cognitive function among poor, urban-dwelling persons.
大量证据表明，饮食摄入不足与认知功能下降有关。然而，很少有研究在城市贫困环境中考察这种关系。我们的简要综述表明：（a）总体饮食质量较高可能在最贫困人群的认知功能中发挥特别重要的作用；（b）维生素E摄入量增加与更好的认知表现有关，至少部分是通过减少抑郁症状实现的。近期更广泛的文献强烈表明饮食对学习和记忆具有有益作用，并且可能对其他认知领域产生协同影响。然而，城市贫困人口对健康饮食的坚持可能受到成本和获取途径等因素的限制。在此，我们提出了几个可能调节和介导城市贫困人口饮食与认知关系的因素。未来的研究应关注影响饮食在城市贫困人口认知功能中作用的各种因素之间的复杂相互作用。
