Personality traits shape dietary choices, reveals groundbreaking study

A recent meta-analysis published in Appetite has found that individuals who identify as vegetarians or vegans tend to score higher in the personality traits of Openness and Agreeableness compared to omnivores. The study, which included data from 69,576 individuals across various countries, also revealed that Openness was the only significant personality trait difference between vegetarians and vegans, with vegans scoring higher. However, there were no consistent associations between other personality traits (Neuroticism, Extraversion, and Conscientiousness) and dietary choices. The study suggests that Openness and Agreeableness are key personality traits linked to vegetarian and vegan diets, but further research is needed to understand the causal mechanisms behind these connections.
