I know that there are probably different times for certain situations but was just curious as to a rule of thumb of how long it took to digest food, how long it was in your stomach, how long it takes for it to be excreted through the entire system etc. Does any absorption occur in the stomach or is it basically jsut the small intestine? For some reason I thought food was in your stomach for up to four hours, and took about 2 days to be passed all the way through your system, but I am not sure. Wondering if anyone here had some information of the top of his/her head. Thanks in advance.

Alright thanks. Makes sense about it depending on the person and what is eaten. I was just sitting here thinking how weird it is that its in the body for that long (hard to think you have that much length of intestine inside). I know that food passes through the pyloric canal when leaving the stomach, but how is it pushed through there? When does the stomach decide its time to let food through? Is it all at once or is it just a little at a time? I know these probably dont fit in the nutrition section, but thought I could maybe get some answers here.

Turkey - 2 to 2 ? hours digestion time (without skin)
Beef, lamb - 3 to 4 hours digestion time
Pork - 4? 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.)It is the mark of an educated mind to be able to entertain a thought without accepting it.
