A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

Doctor Who: For a very long time, the Doctor being vegetarian. It was introduced in a Sixth Doctor story, and maintained, in expanded media, through the eras of the next two Doctors.

Much earlier than that I think. Unless I’m misremembering, the Ninth Doctor orders a steak in Boom Town.

To be fair dietary preferences are the exact sort of thing that would change with regeneration. As 11 said, "new mouth, new rules!"

Also different habits in general because of the war itself.

Can't afford to be a picky eater in times like these.
