I am so glad Bines asked me this question! I'm putting it here for future reference, and if anyone else is curious. Thanks Bines!
DIGESTION TIME OF VARIOUS FOODS
(approx. time spent in stomach before emptying)
Water when stomach is empty, leaves immediately and goes into intestines,
Juices Fruit vegetables, vegetable broth - 15 to 20 minutes.
Semi-liquid (blended salad, vegetables or fruits) - 20 to 30 min.
Watermelon - 20 min.digestion time.
Other melons - Canteloupe, Cranshaw, Honeydew etc. - 30 min.
Oranges, grapefruit, grapes - 30 min.
Apples, pears, peaches, cherries etc. - digest in 40 min.
Raw tossed salad vegetables - tomato, lettuces, cucumber, celery, red or green pepper, other succulent vegetables - 30 to 40 min. digestion. -
Steamed or cooked vegetables
Leafy vegetables - escarole, spinach, kale, collards etc. - 40 min. - Zucchini, broccoli, cauliflower, string beans, yellow squash, corn on cob - all 45 min. digestion time
Root vegetables - carrots, beets, parsnips, turnips etc. - 50 min.
Semi-Concentrated Carbohydrates - Starches
Jerusalem artichokes & leafy, acorn & butternut squashes, corn, potatoes, sweet potatoes, yam, chestnuts - all 60 min. digestion.
Concentrated Carbohydrates - Grains
Brown rice, millet, buckwheat, cornmeal, oats (first 3 vegetables best) - 90 min.
Legumes & Beans - (Concentrated Carbohydrate & Protein)
Lentils, limas, chick peas, peas, pigeon peas, kidney beans, etc. - 90 min. digestion time
soy beans -120 min. digestion time
Seeds & Nuts
Seeds - Sunflower, pumpkin, pepita, sesame - Digestive time approx. 2 hours.
Nuts - Almonds, filberts, peanuts (raw), cashews, brazil, walnuts, pecans etc. - 2 1/2 to 3 hours to digest.
Skim milk, cottage or low fat pot cheese or ricotta - approx. 90 min. digestion time
whole milk cottage cheese - 120 min. digestion
whole milk hard cheese - 4 to 5 hours digestion time
Egg yolk - 30 min. digestion time
Whole egg - 45 min.
Fish - cod, scrod, flounder, sole seafood - 30 min. digestion time
Fish - salmon, salmon trout, herring, (more fatty fish) - 45 min. to 60 digestion time
Chicken - 1½ to 2 hours digestion time (without skin)
Turkey - 2 to 2 ¼ hours digestion time (without skin)
Beef, lamb - 3 to 4 hours digestion time
Pork - 4½ to 5 hours digestion time
Note1: raw animal proteins have much faster digestion times than the above times for cooked/heated animal proteins.
Note2: The digestion times given are under an ideal situation of eating only one food, chewing well, and having efficient digestion, as is the case e.g. after a fast. They are digestion times for optimally healthy persons, with good eating habits. The digestion times are to a large part derived from Dr. Gian-Cursio's and Dr. Bass' practices.
Digestion times are much longer on a conventional diet, and for persons with non-optimized digestive systems, or persons lacking in energy, and for meals with many ingredients put together haphazardly = not in the optimum sequential order.)
Added for Sarah! haha:
After stomach emptying: Small intestinal tract Bearing in mind that the small intestine is about 20 feet long, its motility is a very efficient process, as all its contents are moved right the way through in about 4 hours. In the immediate response to eating, the characteristics of motility are geared up to preventing movement of contents from the upper regions, so as to allow digestion and absorption to take place here. The rate of movement of the residual contents after these events is then very rapid.
Large Intestine Transit
Unlike the emptying of the stomach and the movement through the small intestine, transit through the colon is slow and in normal subjects it takes up to 48 hours for the contents to move through the ascending, transverse and descending segments of the colon to the rectum to defecation (potty time!!).
Now, I totally understand their surprises when I pooped out the camera in under 6 hours! I am amazing! Just call me Wonder Pooper! No please don't! Thanks Bines and Sarah!
