Tonight while speaking speaking with my MIL she mentioned that she had heard that it takes a donut two weeks to digest. I don't believe this as I can't see what the reasoning would be behind that line of thought. Are there any references out there on the internet or library land that discuss digestion times for various food products?

I can't find any "digestion times" per se, but I can find many tables of Glycemic Index, which is:
quote:
The Glycemic Index of a food is derived by comparing the rate of digestion to that that food, with the rate of digestion of pure glucose. Glucose* is assigned a Glycemic Index of 100, and the tested food is charted against this standard.

* glucose if the most widely accepted reference food, however some other systems use white bread instead.

Foods with a high Glycemic Index (70 and above) are those that break down quickly and cause a spike in blood sugar levels.

Foods with a low Glycemic Index (55 and below) break down more slowly and steadily, resulting a more sustained supply of energy.

Donuts aren't specifically mentioned, but the "Breads" section reads as:
quote:
  • Bagel 72
  • Kaiser roll 73
  • Pita 57
  • Pumpernickel 49
  • Rye 64
  • Rye, whole 50
  • White 72
  • Whole wheat 72
  • Waffles 76

So, with bagels, rolls, white bread, whole wheat bread, and waffles all being on the "quick" end of the scale, I can't see a donut digesting much slower.

I dunno - Dunkin Donuts make a few stodgy numbers that take a while to process... [Wink]

The average human digestive system will settle a doughnut mouth to arse in about 6 hours - they're fried flour, water and sugar - all basic food elements the body usually digests readily....

Maybe she heard that it takes that long to burn the extra calories somehow, and misunderstood the message as a digestion problem. As the others have said, it doesn't make sense that a light, fluffy donut could take any longer to digest than bread.

The answer is "it depends." Bowel transit time is the time it takes food to go from mouth to anus. 12-48 hours is a good average. Food that is not broken down & absorbed by the body just keeps movin' along. So any unused doughnut parts--well, it all comes out in the end.

What if it's a donut covered with chewing gum?

I wonder if people who believe things like "it takes two weeks to digest" some particular food ever ponder where the stuff goes for those two weeks.

If donuts take two weeks to digest, do they sit in your stomach the whole time? If so, I'd think that anyone who ate a few donuts at one sitting wouldn't feel hungry again for the next few weeks, because his stomach would be perpetually full of undigested donut matter. Do donuts sit around your intestines for two weeks? If so, how does anything you eat after the donuts make its way through your digestive system? Wouldn't it be kind of painful not to have a bowel movement for so long?

I guess that this is based on an alternative system of human biology in which people have multiple parallel digestive tracks for digesting various foods at different rates.

This sounds like another bogus proclaimation from the field of quack medicine. I've heard similar claims that it takes one year/five years/etc, to digest meat, and that we carry all the meat that we've eaten in the past year in out lower intestines.

People that make a living performing enemas on hypocondriacs will make ridiculous claims about what was extracted during the enema. They do this to get the rube to come back for more treatments.
