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?

When performing intake on a person and asking about Ins and Outs you follow the general rule of “Once every three days or three times in one day and everything in between.” It’s the general rule for how often is normal. When it breaks that rule you ask more questions: what prescription medications do you take. Changes to diet. Stress. Dehydration. Trauma. Etc.
