Headline is megaclickbait. The research is about how healthier gut microbiomes correlate with improved pooping and nothing about how it impacts your health.

From the article’s “key takeaways”:

> By considering interindividual and intraindividual differences in transit time in human studies, diet–microbiota interactions and disease-related microbiome signatures may be better elucidated.

There is also an entire section entitled “The role of gut transit time in health and disease”

None of this is summarized in the posted article. It's in the research paper which I didn't read because the article seemed like fluff.

that's the most insane thing i read today. kudos to your curiosity

Then you'll love https://onlinelibrary.wiley.com/doi/full/10.1111/jpc.14309 "Six paediatric health-care professionals were recruited to swallow a Lego head."

omg this article is wild lol

> To standardise bowel habit between participants, we developed a Stool Hardness and Transit (SHAT) score to look at stool consistency over time. The SHAT score is the sum of the Bristol Stool Chart scores over a specific time period divided by that time period in days.

> Post-ingestion, stools were monitored and examined in search of the excreted item. The search was conducted on an individual basis, and search technique was decided by the participant. The primary outcome was the Found and Retrieved Time (FART) score.

This is why I suspect that GLP-1 agonist medications have the potential to cause a cascade of negative consequences for the health of some people. One of the mechanisms is slowed gastric emptying which leads to decreased motility of the small intestine as a side effect. They do tell people to drink more water to counteract this. It just seems like trading one set of problems for another so hopefully doctor and patien…

I got food poisoning on a GLP-1 and the slowed gastric emptying made it a hellish 5 days.

I did quite some experimenting with this. Fruit moves fastest and green leaves. Meat, cheese, oil and fats slowest. But we often eat combinations: and the slowest component of your food determines the speed of the whole. Also: it's a one lane road and "over taking" is not possible. So, eating a fast moving meal after a slow moving meal results in the fast mover getting stuck behind the slow mover. Hence I start my da…

Eating bitter greens can cause the body to secrete more bile and that speeds up fat digestion.

I use TUDCA for that though it can make me gassy if I take too much.

I did not mention stomach. I meant the GI-tract as a whole. I've used food coloring and indigestibles (like corn kernels) to do experiments on whether meals can "overtake" or "merge" or "join" with other meals into poops.

Food coloring is a liquid dye. It will mix with whatever chyme it encounters in the stomach and small intestine, dyeing a large portion of the stool. It does not prove that food stayed in a single-file line. Also, again the GI-tract as a whole is also not a "one-lane road". Please educate yourself and do not do "experiments" on yourself. A good place to start learning more would be: https://accessmedicine.mhmedical.c…

You are very judgey and controlling. Maybe some prune juice would help?

There have been alternative (often mad) health proponents who have insisted upon only eating fruit in the morning for years - similar(ish) reasons. I think there is probably something to it.

I mean the most obvious reason is fibers

For me the most obvious reason is that we are primates and most primates have a fruit heavy diet. So I believe that's a reason for our human bodies to be very well adapted to fruit.

And that's the fibers, vitamins, minerals and sugars... The whole package.

Isn't slow food going through your body during sleep something that'll impact your sleep quality? When you wake up you are basically fasting so your body is ready to take a hit. Slow food will go through your body faster when you eat it in the first half of your day.

I found the same food goes about as fast (on a rather empty GI tract) no matter when eaten.

Slow food takes about 24h for me (so even when eaten early).

Have you found that coffee speed things up?

I cannot stand the taste coffee. So no data from my side.
