The Association Between Peanut and Peanut Butter Consumption and Cognitive Function
Abstract Objectives This study investigated the association of peanut and peanut butter (P/PB) consumption and cognitive function. Methods Using 2011–2014 NHANES data, we selected 60–80 year-olds who had two 24-hour diet recalls, cognitive function tests, and education information. P/PB and tree nut (TN) consumption was measured as well as the participant's performance on the CERAD Word Learning subtest (CERAD W-L), Animal Fluency test (AFT), and the Digit Symbol Substitution test (DSST). Scores from the three cognitive tests were dichotomized. Individuals were classified as either P/PB consumers or non-consumers and TN consumers or non-consumers. Unadjusted and adjusted logistic regression models examined associations between P/PB consumption, TN consumption, age, gender, education and cognitive function. Results Among the 2,857 individuals examined, participants who did not consume P/PB were more likely to do poorly on the CERAD W-L (adjusted OR = 1.55, 95% CI 1.25–1.92), AFT (adjusted OR = 1.30, 95% CI 1.06–1.60), and DSST (adjusted OR = 1.37, 95% CI 1.10–1.71) when compared to those who did consume P/PB. Conclusions These findings suggest an association between P/PB consumption and cognitive function. Funding Sources The Peanut Institute provided funding.
