Ultra-processed food intake and impairment across multiple cognitive domains in nationally representative older U.S. adults.

ABSTRACT:

Introduction

Ultra-processed food (UPF) consumption, which accounts for more than 50% of energy intake in the U.S., has steadily increased among older adults over the past decade. UPF consumption is associated with overall cognitive decline, but few studies have examined the associations between UPF consumption and individual cognitive domains.
