Background and Aim: Memory indicates as one of the best function of brain. It is influenced by environmental factor such as diet. In addition, people have major interest to some palatable foods (such as different kinds of chocolate and sugar). Hence, they interest to intake them repeatedly. Methods: Male Wistar rats were randomly allocated to five groups of control, dark chocolate (۹۷% cocoa), milk chocolate (۶۰% cocoa), white chocolate (۱۰% cocoa) and sugar (۰% cocoa) for ۱۴ days. Memory was evaluated using by passive avoidance test at intervals of ۱, ۷, and ۱۴ days after a foot shock. Results: This study investigated the effect of different addictive foods such as kinds of chocolate with various percentage of cocoa and sugar (from low to high), and even sugar on memory trend through ۱۴ days in male rats. Conclusion: Results: Consumption of dark and milk chocolates particularly improved memory after ۱ day and especially after ۷ days. The pattern of memory trend were similar in dark and milk chocolate diets. In addition, there were some differences between dark and milk chocolate diets with both control and sugar groups. In the initial ۷ days of experiment, the decreased trend of memory was slower in the milk and dark chocolate diets than common and sugar diet groups. Also, only the dark chocolate diet showed a significant enhancement on memory after ۱۴ days. White chocolate and sugar did not have considerable effect on memory after ۱, ۷ and ۱۴ days. Conclusion: It concluded that with increasing of the percentage of cocoa in different types of chocolate, the memory trend improves in initial ۷ days, while this improvement is not considerable in the final ۷ days. Though dark chocolate (as the chocolate with highest cocoa) improves memory after ۱۴ days compared to control group.
