I wish they put this on screen in Germany, too (though in German, maybe, instead of Japanese). In cooking shows, I always fear they throw the food in the gargabe. With that note on the screen, if they do throw it in the garbage, at least they would be evil liars. Which might be less likely, and so I could feel better.

You're engaging in a decadent activity (watching TV) that "wastes" all kinds of resources but are worried about this one in particular (food) even though we have more than enough of it to go around?

Regardless of disclaimer, I’m sure the food cooked on TV going to waste is not the norm - dozens of people are on set when filming any of these shows, and they’re all curious to try the dish.

On French TV shows they state (verbally, not with a standard text shown on screen) that the leftovers are given to the Red Cross (and some to the staff).

Food waste is utterly meaningless to the environmental cost of producing and streaming a TV show.

For instance, streaming anything in 4k takes an enormous amount of water and energy.

And also in Youtube "I ate every dish on the menu at restaurant XYZ". I really like these, but man do I feel bad afterwards. Please tell me nothing went to waste!
