Comfort food is food that provides a nostalgic or sentimental value to someone, and may be characterized by its high caloric nature, high carbohydrate level, or simple preparation. The nostalgia may be specific to an individual, or it may apply to a specific culture.
The term comfort food has been traced back at least to 1966, when the Palm Beach Post used it in a story: "Adults, when under severe emotional stress, turn to what could be called ‘comfort food’—food associated with the security of childhood, like mother’s poached egg or famous chicken soup." They are believed to be a great coping mechanism for rapidly soothing negative feelings.
Comfort foods may be consumed to positively pique emotions, to relieve negative psychological effects or to increase positive feelings.
One study divided college-students' comfort-food identifications into four categories (nostalgic foods, indulgence foods, convenience foods, and physical comfort foods) with a special emphasis on the deliberate selection of particular foods to modify mood or effect, and indications that the medical-therapeutic use of particular foods may ultimately be a matter of mood-alteration.
The identification of particular items as comfort food may be idiosyncratic, though patterns are detectable. In one study of American preferences, "males preferred warm, hearty, meal-related comfort foods (such as steak, casseroles, and soup) while females instead preferred comfort foods that were more snack related (such as chocolate and ice cream). In addition, younger people preferred more snack-related comfort foods compared to those over 55 years of age." The study also revealed strong connections between consumption of comfort foods and feelings of guilt. An article, "The Myth of Comfort Food" asserted that men tend to choose these types of savory comfort foods because they remind them of being "pampered" or spoiled, while women choose snack-related foods because they are associated with low amounts of work and less "cleanup." It also suggested that women are more likely to reach for unhealthier foods in times of stress due to more weight-conscious mindsets.
