Explore the associations between personality traits and diet

· TGI - Health

This study was to explore the associations between food and nutrient intake, personality traits and resilience.

Personality traits make up the unique combination of emotional, cognitive, and behavioral traits that characterize an individual and are relatively stable in adulthood. Personality is associated with several health outcomes, which could be explained by behavioral factors associated with personality.

Major personality dimensions are neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness – also known as the Big Five. The Five-Factor Model (FFM) distinguishes these five dimensions. FFM is among the most commonly used dimensional conceptualizations of personality in research and defines normative personality.

The FFM personality traits are associated with



Cardiovascular disease



Conscientiousness and neuroticism – have been found to be predictive of health behaviors

{Conscientiousness – tendency to be dutiful, goal-oriented, persistent

Neuroticism – characterized by anxiety, depression, hostility, impulsivity}

To date, only a few studies have explored the associations between personality traits and diet.

High neuroticism – has been associated with high intakes of sugar and fats

Low neuroticism – with a Mediterranean style dietary pattern (characterized by vegetables, fish, pasta, oil and vinegar dressing, tomato-based sauces).

High openness – tendency to be open to novelty: ideas, aesthetics, emotions – has also been associated with a Mediterranean style dietary pattern.

High agreeableness (tendency to be trustworthy, compliant, and straightforward) and Conscientiousness – have been associated with high fruit intake and a health aware dietary pattern.

High agreeableness – is also associated with high vegetable intake.

However, one of the consistently replicated personality profiles is RESILIENCE.

Individuals encompassing this (Resilience) profile are low in neuroticism and high in extraversion, openness, agreeableness, and conscientiousness.

Generally the concept of resilience encompasses the dynamic processes of adaptation during adverse life events, and it has been associated with favorable health behaviors and high intakes of fruits and vegetables.

No previous study has tested the associations of resilience and the whole diet. Therefore the current study was aimed to study the associations between personality traits, resilience, and food and nutrient intake.

The study suggests that healthy dietary habits, such as a high intake of fruits and vegetables, would be associated with low neuroticism and high extraversion, openness, agreeableness and conscientiousness, as well as with resilience. The study also found that these associations were stronger in women than in men.
