A "Comfort Food" is a familiar food that a person eats because doing so relieves stress and anxiety and increases contentment and comfort (hence the name). It sparks happy memories, brings back feelings of security and safety, and thus can easily lift a person's mood.
Comfort food for most people tends to also be their favorite food, or the food they enjoyed the most while growing up. In his book A Cook's Tour, Celebrity Chef and Television Host Anthony Bourdain noted that, among big name chefs who specialize in fine cuisine at their restaurants, the most common type of answer to "If you were about to die and had time for one last meal, what would it be?" were meals like "my Grandmother's meat loaf" or "a nice hot ham-and-cheese sandwich" or "oreos and a tall glass of ice cold milk". Other common answers were things like "a Big Mac", "mint chocolate chip ice cream", "an entire bag of Lay's Barbecue chips", and "a chili dog".
In other words, Comfort Food.
Because corporations know a cash cow when they see it, there are entire restaurant chains devoted to serving you comfort food, like Bob Evans, Cracker Barrel, and Boston Market.
