Linking Personality Traits to Mediterranean Diet Adherence and Exploring Gene-Diet Interactions in Neuroticism.

ABSTRACT:

Background and objectives

There is adherence to a healthy Mediterranean diet (MedDiet), but adherence varies widely. Precision nutrition is increasingly interested in individual characteristics influencing diet adherence, but few studies have examined personality traits. Our main aim was to investigate the association between personality traits and MedDiet adherence. Our secondary aims were to explore genome-wide genetic variants associated with neuroticism, including replication of previous findings, as well as to explore gene-MedDiet interactions.

Methods

We analyzed participants (aged 55-75) in the PREDIMED-Plus-Valencia study and measured clinical, lifestyle, and genetic factors. The Eysenck Personality Questionnaire-Revised (EPQ-R) was used to measure neuroticism, psych
