Food
From Tardis Wiki, the free Doctor Who reference
"Food" or "foodstuff" was the name given to edible objects. It was consumed around the entire universe, by many species and different alien races. "Vittles" was a colloquial name for food. (TV: Horror of Fang Rock)
On planet Earth, a vast variety of foods were available, such as chips, (TV: School Reunion) steak, (TV: Sky) fruit, (TV: An Unearthly Child) turkey (TV: The Time of the Doctor) and many others.
The Doctor was rather fond of Earth food, most likely because he liked Earth so much in general. In particular, he had a sweet spot for jelly babies, (TV: Robot, Doctor Who) celery (TV: Castrovalva) and fish fingers and custard (TV: The Eleventh Hour) over the course of his many incarnations.
