Modern scientific evidence supports the long-held notion that our eating habits reflect who we are. A comprehensive 2024 study by Aristotle University of Thessaloniki and the University of Thessaly in Greece revealed a clear link between all five personality traits in the Big Five model and food preferences.
The Big Five is a widely recognized psychological model comprising five personality dimensions: openness, conscientiousness, extraversion, agreeableness, and emotional instability. The analysis results showed that each of these five dimensions influences eating behavior.
Conscientious individuals typically maintain healthier eating habits. Conscientiousness reflects self-control, planning ability, and adherence to principles. Those with high levels of conscientiousness often choose healthy foods, maintain a balanced weight, and consistently follow beneficial health routines.
Open individuals are more willing to try new foods. This trait indicates curiosity and a readiness to embrace novel experiences. People who are open tend to consume more fruits and vegetables, maintaining a balanced diet, particularly in middle and old age. They are also less prone to food neophobia, which is the reluctance to try unfamiliar dishes.

Agreeable individuals show a tendency to eat less meat. Agreeableness reflects empathy and altruism. Research indicates that people with this trait consume less meat compared to other personality groups.
Extroverted individuals are more inclined to choose less healthy foods. Extroverts are often sociable, optimistic, and enjoy social interaction. However, they tend to consume more sweet, salty foods, meat, and carbonated soft drinks. The authors suggest this may be because extroverts often evaluate their own health positively, leading them to be more lenient in their food choices and more willing to engage in risky behaviors.
Emotionally unstable individuals consume more sugar. The characteristic of emotional instability reflects a poor ability to cope with stress. Individuals in this group often experience anxiety and insecurity. They tend to eat fewer fruits and vegetables, while consuming more sugar and saturated fat for emotional relief.
