[Objective] This study investigates the dietary preferences of Chinese users from different regions to reveal the differences of dietary culture among them, and then provides suggestion to the catering industry. [Context] It took researchers long period of time to collect small amount of data of dietary preferences. With the development of social media, we could retrieve large-scale dietary information more effectively. [Methods] We collected user-generated content (UGC) from Dianping.com to explore their dietary preferences. [Results] Users’ dietary preferences were very different in the developed regions. Meanwhile, there was significant negative correlation between geographic distances and the similarities of users’ dietary preferences. Finally, users paid more attention to the taste, service and environment of the restaurants. [Conclusions] Research based on the user-generated content can reflect their dietary preferences and reveal the differences of dietary cultures.
