School administrators worry that students may neglect their health; a survey is then carried out on common eating habits. Using the case study paradigm; This quantitative study focuses on understanding the factors that influence students' eating habits. A total of 207 students from a technical vocational university in Taiwan participated in the study. The survey includes common eating habits; more specifically on the types and frequency of food consumed by students. The Big Five Personality Scale is also administered to further understand the factors that influence students' eating habits. The results show that students' eating habits are influenced by various basic demographics, such as gender, grade level, study session and personality. More importantly, the results also show that applied foreign language students scored the highest in personality trait openness. Further additional implications on the Big Five personality are also provided.

As we read on the news, the number of people undergoing plastic surgery is at an all-time high. Beauty products have seen better sales, even during these difficult economic times [1].

ConclusionThe present study exemplifies the use of the Big Five Personality scale to understand the eating habits of EFL learners. This case study, although limited to the sample from a science and technology university, shows that students are more oriented towards healthy lifestyles.
