Food nostalgia and food comfort: the role of social connectedness

We were concerned with the link between nostalgia and comfort in food experiences. In Studies 1 and 2, participants visualised 12 foods (Study 1) or consumed 12 flavour samples (Study 2). Following each respective food experience, they rated each food's capacity to evoke nostalgia and comfort. In preregistered Studies 3 and 4, participants first visualised and wrote about eating either a personally nostalgic food or a regularly consumed food, and then indicated the extent to which the food experience increased nostalgia, social connectedness, and comfort. In cross-sectional Studies 1 and 2, nostalgia associated with food experiences was linked to more comfort, but this relation exhibited greater complexity in experimental Studies 3 and 4. In the latter two studies, nostalgia for food experiences elevated comfort by strengthening social connectedness.
