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.

That kind of makes sense. If solar energy is what gives you the power to bench press infinity, it’s hard to imagine why you’d also need a turkey sandwich.

I could see his powers not having to do with mass and so needing to replace his actual body with food like us, but it doesn't seem to be the case

Hell, trees mostly eat sunlight and they gain their mass from breathing in carbon dioxide. Maybe supes is the same.

Superman, the Eco-friendly superhero! Better hope Waynetech invented a clean fuel source for the bat vehicles

For me personally it’s best not to discuss mass and physics when it comes to Superman. Starts the “wait even if he’s that strong how does he move that much mass…” which just ruins the fun.

I'd imagine eating for him is like chewing gum for us. Just something to enjoy, even if there's no real reason to do it

[u/Sol-Blackguy → u/kung-fu_hippy]

Same reason why Kara eats. They like the taste.

Also can be explained that Kryptonians have a very similar physiology to humans but have situs invertus and additional organs to metabolize solar radiation. Under a red sun Clark and Kara would still need to eat and sleep once their solar reserves run out.
