Diet modification to alter the course of age-related cognitive decline is becoming increasingly important. Few observational findings suggest that dairy food intake may be positively related to cognitive function, but research in this novel area is limited. The aim of this study was to investigate whether dairy food intake is associated with cognitive function, before and after adjustment for cardiovascular, lifestyle and dietary factors. To do this, a cross-sectional analyses of a subset of the community-based Maine-Syracuse Longitudinal Study (MSLS) sample ( = 972) was undertaken. It was determined that participants who consumed dairy products at least once per day had significantly higher scores on multiple domains of cognitive function compared with those who never or rarely consumed dairy foods, adjusting for cardiovascular risk factors, lifestyle and dietary factors. Frequent dairy food intake is associated with better cognitive performance but underlying causal mechanisms are still to be determined.
通过饮食调整来改变与年龄相关的认知衰退进程变得越来越重要。很少有观察结果表明，乳制品摄入量可能与认知功能呈正相关，但这一全新领域的研究有限。本研究的目的是在对心血管、生活方式和饮食因素进行调整前后，调查乳制品摄入量是否与认知功能相关。为此，对基于社区的缅因州锡拉丘兹纵向研究（MSLS）样本（n = 972）的一个子集进行了横断面分析。结果确定，与从不或很少食用乳制品的参与者相比，每天至少食用一次乳制品的参与者在认知功能的多个领域得分显著更高，这是在对心血管危险因素、生活方式和饮食因素进行调整之后得出的结果。经常摄入乳制品与更好的认知表现相关，但潜在的因果机制仍有待确定。
