Association between alcoholic (poly)phenol-rich beverage consumption and cognitive status in older adults living in a Mediterranean area

Abstract

The prevalence of cognitive disorders is growing and evidence suggests the putative role of plant-based foods and beverages containing (poly)phenols. The aim of this study was to explore the association between the consumption of (poly)phenol-rich beverages, including wine and beer, resveratrol intake, and cognitive status in a cohort of older adults. The dietary intakes were assessed using a validated food frequency questionnaire, and cognitive status using the Short Portable Mental Status Questionnaire. Multivariate logistic regression analyses showed that individuals in the second and third tertile of red wine consumption were less likely to have cognitive impairment than those in the first tertile. In contrast, only individuals in the highest tertile of white wine intake were having lower odds of cognitive impairment. No significant results were found for beer intake. Individuals with higher resveratrol intake were less likely to have cognitive impairment. In conclusion, consumption of (poly)phenol-rich beverages may potentially affect cognition among older adults.
