Estimates of the speed of the food through the gastrointestinal tract are between 12 and 73 hours with about 24 hours on average. If the speed is too slow or too fast it can be adjusted by the diet. For instance, by eating more fruit and veg you can speed up the transition. You can measure the speed by not eating sweetcorn for a week and then eating a handful of corn, which are not digested, and check when they are visible in your stool.
