Digestion Transit Time Activity

Materials Needed

Either one boiled beet or one boiled cob of corn.

To boil the beet, peel the beet and place it in a small pot on the stove. Cover with water and add 1 tablespoon of apple cider vinegar and a pinch of salt and boil until semi-soft (about 20-30 minutes).

To boil the corn, shuck and place in a medium pot on the stove. Cover with water and a big pinch of salt and boil until semi-soft (about 5 minutes).


To identify your digestion transit time. The time it takes for your food to enter your stomach, move to the small intestine for nutrient absorption and then onto the large intestine for further digestion, absorption of water and elimination of undigested food waste.

In a healthy digestive system, food moves through the stomach and small intestine in about 6 to 8 hours. The next leg of the journey through the large intestine takes about 40 hours, on average. It is important to note that this journey can take as little as 33 hours in a man’s body whereas it may take more like 47 hours for the food to make its way through a woman’s large intestine.


All you will need to do is eat either the beet or the corn and keep an eye on your stool for the bright red color of the beet or undigested corn kernel skins to appear.

*If it takes over 50 hours for the indicators to appear, you may be experiencing constipation. Keep in mind though, faster is not better. If your stool shows signs of the beet or corn in less than 10 hours, the food may not be spending enough time in your body for you to receive the full nutrient benefits.
