Caffeinated Coffee and Tea Consumption, Genetic Variation and Cognitive Function in the UK Biobank.

ABSTRACT:

Background

Coffee and tea are the major contributors of caffeine in the diet. Evidence points to the premise that caffeine may benefit cognition.

Objective

We examined the associations of habitual regular coffee or tea and caffeine intake with cognitive function whilst additionally accounting for genetic variation in caffeine metabolism.

Methods

We included white participants aged 37-73 y from the UK Biobank who provided biological samples and completed touchscreen questionnaires regarding sociodemographic factors, medical history, lifestyle, and diet. Habitual caffeine-containing coffee and tea intake was self-reported in cups/day and used to estimate caffeine intake. Between 97,369 and 445,786 participants with data also completed ≥1 of 7 self-administered cognitive
