During digestion, your food is chewed and swallowed, then acid and digestive enzymes are added as it moves through your stomach. Upon leaving your stomach, the food is squeezed through your 15-21 foot long small intestine. As it moves through, nutrients and water are absorbed for use by your body. It continues to move by rippling waves of muscular contractions through your large intestine. Whatever hasn't been digested and absorbed by your intestines combines with water, bacteria, and various excreted substances to become stool. Stool is expelled from your body through your anus. The time this entire process takes (your bowel transit time) is one measure of your bowel function. There an easy way to measure your bowel transit time in the privacy of your home: food markers. There are many foods that, either through color, texture, or both, show up at the end of the journey in a recognizable fashion: beets, blueberries, cherry tomatoes, and corn are a few that I have found to be very reliable. (I suggest blueberries or cherry tomatoes, as beets and corn are both high glycemic foods that support yeast growth.) A home bowel transit test can help you to become more aware of your bowel function level and to see how different foods in your diet can effect the rate at which food moves through your digestive tract; the faster the food moves through the digestive tract, the less time your system has for yeast to grow and establish colonies in your system. If you plan to use food markers to measure bowel transit time at home, do not eat these foods for a few days before starting the test. To test your fastest transit time, do not eat anything after 6 PM at night. After 8 AM the next morning, eat a small container (about a cup and a half to two cups) of your chosen marker food. Do not eat anything else until after noon. When your marker food exits, merely subrtact the time you ate the marker food from the time it exits. To test your slowest transit time, eat normally through the day, and eat a large dinner including foods from several food groups: meat, grain, green vegetables and starch (potatoes, rice, etc.) Add dessert if you like, to maximize the starting status. Eat nothing after 6 PM. The next morning, eat your food marker morning meal, and again wait until after noon to return to normal eating. The time difference between the food marker consumption and the marker exit is your longest transit time. If you are checking both transit times in the same week, use two different food markers. |
