How fast can food pass through the body?

Question

I have read somewhere that it is normal to defecate about once a day. This leads me to think that it takes about 24h for food to pass through the body under normal circumstances.

Now lets say you eat some bad sushi that triggers “the runs” within an hour.
When you then defecate, is it the actual sushi that comes out or is it just the food you ate before the sushi?

Also, how fast could food theoretically go from mouth to anus?

My wife has collitis and she will poop out barely digested food after a few hours. It’s a serious condition.
