Ate cooked butternut squash & cooked carrots. 4.5 hrs later had bowel movement & saw it in my stool.does it make sense that it passed thru so quickly?

Bowel transit time: Normally takes ~ 2.5 -5 hours in the stomach and 2.5-5 in the intestines, then 12 + in the colon. But if you have only a diet of vegetables and drink water/coffee which is a cathartic, it is possible to get more rapid transit time, as by 4-5 hours there is food in colon. Alternatively could be from yesterday. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/basics/transit.html
