Abstract

BackgroundThe Mediterranean Diet (MD) is well-studied for slowing cognitive declines. Few studies have examined how a Western MD (wMD) may impact cognitive function.ObjectiveThis study examined whether a wMD predicted less cognitive decline over 9 years in a national sample of American adults. The measures were episodic memory (EM) and executive functioning (EF) at baseline and 9 years follow-up.MethodsThis is a secondary analysis of the Midlife in the United States Study (MIDUS), using a longitudinal cohort design with cross-sectional dietary data. Participants in this study had data from Waves 2 and 3 of MIDUS (

Research summary

The paper claims that adherence to a Western Mediterranean diet predicts less cognitive decline in episodic memory over a 9-year period. This study is relevant as it explores dietary influences on cognitive aging, which is a significant aspect of longevity research.
