When you’re back home, are there certain foods or restaurants that you can’t wait to visit? Or if you visit your favorite local festival, is there a certain dessert you’re always dying to try? These experiences demonstrate the everyday phenomenon of food nostalgia.Scientific research is showing that there is a unique link between our memories and the food that we eat. When we eat foods at certain events or at certain times of the year, we can create powerful associations between that food and our good feelings. These good memories can alter our evaluation of how good a food is, and can also powerfully alter our mood.
