With regards to poo (tehee), frequent bowel movements are way overrated. A lot of the time that means that the food is being pushed through without as much absorption of nutrients. What really matters is the quality of it. Is it thick and one piece, two pieces. eight pieces? Is there undigested matter? That sort of stuff is way more important than frequency. I eat a lot of vegetables and go once a day but someone eating less vegetables than I do would be less frequent. If you're into the many days with nothing, then there's probably a problem, but total transit time is of little importance as long as you are eating real food, taking probiotics and staying away from that which irritates your GI tract.
