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?

I have IBS-D and I can honestly say I’ve both drank red kool-aid and had red diarrhea 15 minutes later and ate a burrito with corn and had the corn exit my body 20 minutes later. That’s why I currently only eat one small meal a day, which always immediately leads to a trip to the bathroom
