Investigating walnut consumption and cognitive trajectories in a representative sample of older US adults.

ABSTRACT:

Objective

Existing research suggests walnut intake may be associated with better cognitive function in older adults, yet few studies utilise longitudinal data from observational studies of ageing populations. Our objective was to estimate the association between whole walnut intake and cognitive change in a representative sample of older Americans.

Walnut consumption was defined as a categorical measure (none, low intake (0·01-0·08 1 oz. servings per day) and moderate intake (>0·08 1 oz. servings per day)) and cognitive function was measured using the Telephone Interview for Cognitive Status. Latent growth modelling estimated the association between walnut consumption and trajec
