The blogs of the scientists who lived on fake Mars for a year in Hawaii make it clear how important food is for astronaut's mental health as well as physical nutritional needs: https://walking-on-red-dust.com/2016/06/18/domemade-food/
A couple of years ago I listened to a talk by a plant scientist from Florida. They had some experiments, seedlings growing in the International Space Station. Every day one of the astronauts took photos of the seedlings, to document growth. He said that it was more or less everyone's favorite task in the space station. "Today I get to look at the plants", the astronauts would say.
