Six to eight hours
However for clear understanding, digestion time will solely depend on the type of food consumed by an individual. For example fruit and veggies take 30 minutes to digest, liquids take about 20 minutes, carbohydrates take 3 hours and meat takes 24 hours. This is why it is advisable to drink lots of water, eat lots of fruit and veg, but limit your consumption of meat. Food digestion rates also depend on the gut transit. Food will pass through here slowly if you do not exercise sufficiently,people who exercise frequently will have faster digestion ability. The average time for food to stay in the gut transit is 24 to 56 hours. If food stays here for less than 2 hours it is a sign of very poor digestion. This will lead to dehydration, and there will be less time for nutrient absorption Your body uses mechanical and chemical means to digest food and it varies depending on the individual according to Michael Picco, M.D With Mayo Clinic gastroenterologist. The digestion process takes between 24 and 72 hours, six to eight hours to pass through your stomach and small intestine. Then the food enters your large intestine (colon) for further digestion and absorption of water. Elimination of undigested food residue usually begins after 24 hours. Complete elimination from the body may take several days.. Mayo Clinic Slide Show: See How Your Digestive System Works.  This will usually take 5 to 6 hours. The food then enters the colon for further digestion and water re-absorption before defecation. The time from it's entering the colon to defecation is about 12 to 24 hours. Thus, the time for food to travel from one end to the other probably ranges from about 20 to 30 hours. The food spends around 30 minutes - 2 hours getting to the small intestine, 2-6 hours getting all the nutrients extracted, and the rest in the intestines. Answer 3 It'll take about 24 hours to go through your whole body. Hydration and digestive health affect how long it takes your body to digest food. Food moves faster through the digestive track when the body is hydrated. You can estimate how long it will take based on the makeup of the food you eat. For most healthy adults, digestion takes between 24 and 72 hours. Carbohydrates digest faster than proteins, and proteins faster than fats. Fats. It takes eight hours for food to pass from the mouth to the large intestine or colon; fats take between six and eight hours. Examples of food containing fats include meat, nuts, oils and avocados. They are the most complex of the molecules. Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). The average transit time through just the large intestine (colon) was 40 hours, with significant difference between men and women: 33 hours for men, 47 hours for women. Two British doctors studied digestion time in children. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). Total Time. Depending on your individual digestive factors, the entire digestive process from eating food to excreting it via your stool can take between 24 and 72 hours, according to MayoClinic.com. Passing food from your stomach to your small intestine takes about six to eight hours. Digestion through the large intestine typically takes longer than the stomach and small intestines -- about 24 hours, according to MayoClinic.com. From the colon, the digestive material is moved to the rectum, where it remains until you have a bowel movement.
