How fast is your food passing through

Based on what you said above you are fine.  Digestion occurs in the small intestine.  When food enters the stomach, acid and enzymes start breaking it down.   10 to 15 minutes later the colic reflex kicks in which causes the digestive tract to contact and expand, so it works it's way down the digestive system.

 It passes through to the small intestine where the vitamins and minerals are absorbed.  It then drains into the colon whose sole job is to absorb water and act as a store so we don't have to dash to the loo every few minutes.

When I had ileostomy, eating to output was 45 mins to an hour.  So if your going 5 or 6 times a day, it would suggest food is spending enough time to be absorbed.  So time isn't and issue.

Of course it's not the time the food spends in the small intestine that's important, but rather it's efficiency. Enzyme deficiency or acid problems could interfere with absorbstion.  The best thing you can do to increase enzyme production is eating fresh greens, much like you are.  In short unless you have other issues or have had a significant portion of your shall intestine removed or some other reason to suspect malabsorption, your probally fine

What do you mean not absorbed? If blended your giving your making it easy on your body.  Veg is high residue food, meaning volume out is similar to volume in.

Hi Marc-Antoine

High-five to another teenage poucher! I got mine when I was 18, in 2004. I'm not vegetarian but eat very little red meat. Food generally passes through me within an 1h30 up to 3h (or longer sometimes if I can hold it in), and I definitely notice things like tomato skins, grapes/raisins, beetroot and onion are more obvious in the stool. But that would be true even if I had a colon, they would just be less obvious, so I don't worry too much. I think you'd know if you weren't getting enough nutrients from your food.

For me... approximately one hour.

I go to the bathroom 10-15 times a day and 3 at night. Apparently I'm on the high end of the statistics.

If I eat lunch at noon, it starts to come out 2 hours later but the final shipment will leave the body 12-15 hours later.

Good morning Marc-Antoine,

First off, kudos on the diet! That rocks... an inspiration for sure.

I am right there with you, about 90 minutes. I make it work to my benefit by knowing and plan accordingly before road trips and my hockey games. For many years i was concerned about the same thing, nutrient absorption. I have blood work done yearly and the only thing I am ever slightly low in is vit B (which I understand is mainly absorbed in the colon). I think you're totally good.

With that said I did have some issues with absorbing medication. At one time I was on various meds and it turned out I was not absorbing it to the fullest. After discussing this with my doc he advised me to avoid the time-released medications. He may have just pulled that out with no research but I tend to still follow this advice.

I think you're good... (insert choice of 'thumbs up' emoji here)

I am in same range as others have mentioned prior - 60 to 90 minutes. High residue foods may continue to appears to linger 6 to 12 hours.

I too question nutrient absorption 'efficiency'.  I am pretty skinny at 147 lbs and 6'0".  I could eat the entire buffet and would never gain weight - seems pretty unusual for a 52 yr old!  I guess this is a different topic though.

My total colectomy/j pouch (1 step) was done April 30, 2017 (almost 4 months)

My food goes right thru me still..  10-15 minutes after I start eating I have to go to the bathroom. For me, there is no holding it....  I try, but it just doesn't work...

i can see the food I just ate in the toilet....  hoping it starts to build up soon so I can last longer...

I can eat and eat too... it's sorta frustrating because I have lost so much weight and am borderline "underweight" at the moment...
