What is the length of time food generally stays in your body?

I've read that gluten stays in your body for about 2 weeks. Is that true?

How about other foods?

How fast do our bodies use up the food and then get rid of it?

Do chemicals or metals stay in our bodies for long periods of time? (like flouride, aluminum, etc...)

Last night I ate a huge amount of buttered lutefisk, mixed with a lesser amount of boiled potatoes and cabbage salad. All of that is still inside me somewhere, in some form. Msybe dometime tomorrow it will make its way out. What's worrisome is the sulfury nature of the fish....

thhq, in my case grains really plumped up my stools. I agree they went through quickly but they made me poop more often due to volume going out. So, by slowing up, I meant I went from 2-4 poops/day to 1-2.

When I was constipated, I would poop once a day too, but my poo would be hard as rocks and tear my ass open each time. I got to be a pro at applying zinc oxide rectally. Now I have normal poos, yay!

The problem with carbs is not that they digest poorly, but that they digest easily, go right into the bloodstream, and are metabolized or stored. Fat and protein take longer, and I often don't see the net effect of the food weight consumed for a couple days, especially if there was a lot of salt (as in restaurant food).

If you're not allergic to gluten, it's gone in 24 hours with no side effects.

"before digest"? What does that mean. Digestion begins once the food is eaten.

I think the 2 weeks number for gluten is how long it takes the damage/inflammation to heal from a single gluten dose. Gluten itself doesn't sit in your gut for that long.

As for other chemical contaminants, it all depends on what our bodies do with them. Mercury, for instance, likes to associate with proteins and will stick around for a while. Polychlorinated biphenyls (PCBs) are lipophilic molecules and tend to dissolve into our fat deposits so they also stick around for quite a while. Most other water-soluble compounds tend to get eliminated fairly readily. There's no one answer really, it depends on what the characteristics of the contaminant is. Biological half-lives are known for quite a lot of compounds, Google is a good source for tracking these down.

I still laugh about the time in my 20s when I complained to a doctor, "I'm really constipated!" He put on his sympathetic face and asked, "How long has it been since you had a bowel movement?"

I said with great drama, "24 hours!" and he looked at me like I was totally insane. When he realized I was sincere he said, "I wouldn't consider you constipated until it was 3-4 days." That was when I learned there's quite a range of 'normal.' Normal for me used to be 2-4 times per day.

I did slow up a bit when I stopped eating grains, to 1-2 times most days. But color shading and texture indicate food exits in about 24 hours.

Gluten is quite a complicated mixture of the proteins glutenin and gliadin. I very much doubt that it survives intact for 2 weeks given the various enzymes acting on it. That is however not to say that some of the smaller peptide fragments might not be conserved and persist for some time (dependent on the various peptidase enzymes and how effective their activity).

It usually takes about 4 hours for a typical meal to "digest" from the stomach and make its way down into the intestines. Even if you've eaten meat, everything should make its way out within 24 hours. Damage (to the intestinal villi as well as autoimmune reactions) caused by eating gluten may take anywhere from 6 months to 2 years to completely repair. This is why "just one bite" of gluten-containing food once in a while can disrupt the healing process if you are struggling with hypothyroidism, allergies, headaches, skin problems, and other issues that may be a direct result of gluten sensitivity.

For my N=1, eating at my BMR or higher, a day for carbs and 2-3 days for fat/protein. I'd guess that in the mix gluten would clear faster than animal protein, but I don't have a gastro-scope to check. Most toxins are cleared at the liver and kidneys, so would be flushed in a few hours.

It generally stays 4 to 6 hours before digest.
