According to a psychology professor at the University of Massachusetts, food can make us think about the past because of a term called food memories. Unlike a typical memory, food or taste memories make us use all our five senses. They make us feel strongly towards stimulating our brain by reminiscing about our past experiences. For instance, eating Asian food in Singapore can make you think about your mom’s cooking. If she has been cooking Asian food when you were a child, food memories will be triggered.
