Dietary provitamin A and non-provitamin A carotenoid in relation to cognitive function among middle-aged and older adults.

ABSTRACT:

Background

Dietary carotenoids have been associated with better cognitive function, yet evidence regarding the role of different subgroups of carotenoid is inconclusive. This study aimed to investigate the relation of specific carotenoid subgroups to cognitive function.

Methods

We conducted a prospective study among US adults aged 50 years and older based on the Health and Retirement Study from 2013 to 2020. Average daily intakes of dietary provitamin A carotenoid (α-carotene, β-carotene and β-cryptoxanthin), and non-provitamin A carotenoid (lutein-zeaxanthin and lycopene) were assessed by a 163-item semi-quantitative food frequency questionnaire (FFQ) in 2013. In 2016, inflammatory biomarkers of major serum cytokines were assayed. Cognitive function was measured using a com
