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 (N = 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.

乳制品摄入量与认知功能之间的关系：缅因州-雪城纵向研究

改变与年龄相关的认知衰退过程的饮食调整变得越来越重要。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，但在这个新领域的研究是有限的。本研究的目的是调查在调整心血管、生活方式和饮食因素之前和之后，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-雪城纵向研究 (MSLS) 样本 (N = 972) 的一个子集进行了横断面分析。确定每天至少食用一次乳制品的参与者在多个认知功能领域的得分明显高于从不食用或很少食用乳制品的参与者，调整了心血管危险因素，生活方式和饮食因素。频繁摄入乳制品与更好的认知能力有关，但潜在的因果机制仍有待确定。
