ELI5: Does food sit normally in your stomach in space?

I continually see videos of astronauts eating different foods in space like pudding and obviously due to it being space it is in an interesting form. Does it return to a normal state in their stomach?

So, the problem is, if everything is falling together, how can food 'fall' through the digestive system?

The simple answer is that it dosen't! It dosen't in space and it dosen't on earth either. The food in your mouth is pushed to the stomach by muscles in the lining of the tube between mouth and your stomach. Then, in your stomach the digested food is pushed again into your intestines. While in the intestines it is pushed all the way to the, well, to the end.

As a simple experiment, try drinking water while standing on your head. You will be amazed that you can indeed swallow the water. You could even eat a full meal on your head and you would have no problem getting your food where it belongs. You might want to get on your feet, though, before it all gets to. . . . the end!
