Eating habits has always been considered as an important factor in food waste. This paper takes 29 universities, all in different provincial-level regions, as study cases to explore the factors that affect students' wasting behavior. Based on a questionnaire survey of 9192 college students, this paper focuses on the impact of North-South differences on individual food waste behavior, and attempts to answer: Southerners and Northerners, who are more likely to waste food, who waste more food? The results show that compared with the northern native college students, the probability of food waste in the students of the southern region is higher, and the food waste and food waste rate of the students of the southern origins in the college cafeteria are higher than those of the northern students. In order to verify whether the difference in diet patterns between the "rice" model in the south and the "wheat" model in the north is the main reason for the above phenomenon, this paper confirms that the difference between the north and the south diet patterns is the key reason for the fact that the southerners waste more food than the northerners through the mediation effect model. This paper further matches the individual's North-South origin and the North-South position of the colleges and universities. Based on the mode of "Southern students studying in the South", we found that the "Southern tudents going to school in the North" mode has a lower probability of food waste, waste amount and food waste rate. However, under the "Northern students going to school in the South" mode, individuals did not have a low probability of food waste, the weight of waste and food waste rate. Therefore, this paper confirms that the southerners are more wasteful of food than the northerners. And it is proved that the mainstream diet pattern in the north and the south is the leading driving force to the difference in waste.

Key words: food waste, college canteen, North-South difference, mainstream diet
