Due to increasing influence of food industry, during this decade, major changes have been shown, in the dietary habits of the populations. Considering the scientists' ever growing interest in the study of the relation between personality traits and dietary habits, the goal of this study was to establish relation between speciesism, emotional empathy and social dominance orientation of people with diverse dietary habits. 170 vegetarians and 153 omnivores have participated in this study. Scale of speciesism, Scale of emotional empathy and Scale of social dominance orientation have been used as measuring instruments. Results showed that omnivores show greater discrimination towards non-human animals under the assumption that the human race is superior and believe that more powerful groups have the right to dominate over weaker groups, unlike vegetarians. On the other hand, there where no difference in emotional empathy between the two groups. It was also established that the tendency towards discrimination of non-human animals was correlated to having difficulties when it comes to feeling compassionate towards other people's emotions and understandment of the situation that that person is in, based on perception or made-up situation. Tendency to believe in the superiority of the human race was correlated to the more pronounced support of the intergroup differentiation within a specific social structure.
