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 day without and slow food (only fruit, herbs, green leaves, spices, ginger => usually a smoothy); and end the day with slow food (oily food, nuts, seeds, beans; usually combined with green leaves as we need a lot green leaves).
YMMV
But interesting nonetheless, thanks for sharing your findings.
Then, I did not come up with this myself, but found a lot of anecdotals in this direction.
And... I comment on a real science piece that seems to be making similar claims.
And that's the fibers, vitamins, minerals and sugars... The whole package.
Hormonal imbalance is severely underrated as a root cause of common mental health issues like anxiety, depression, etc.
Having fruit in the morning is a little boost without the guilt. Adding in some light exercise, like walking, also helps prime the day. It even gets easier to wake up early for all this the more regularly it's done. It's one big reinforcement cycle for healthy habits.
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.
"Six paediatric health-care professionals were recruited to swallow a Lego head."
> 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.
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.com/book.aspx?bookid=691 if you're intrested.
A great opportunity to add "YMMV"
- Fiber: ^
- Dairy: v
- Coffee: ^^
- NSAIDs: vv
- Ice cream splurges: vvv
YMMV. It's not just determined by the food intakes, there are individual factors.
At a guess, these individual factors start with 1) genetic component to reactions to substances such as lactose and to caffeine. 2) Gut microbiome.
In other words, saying "change diet and you can change the poop schedule" is true, but "with this diet you will definitely get this schedule" is not.
Another reason I do it like this: I get no after diner dip from fast moving food. Slow moving food makes me crash a little, and I prefer to experience that in the evenings.
I did also experiments with fruit (and leaves) only diets. No crashes at all. Nice! But I did crave savory, chewy food a lot.
Best poop-related comment I've seen.
I'll not try though, as I'm vegan for ethical reasons.
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.
Slow food takes about 24h for me (so even when eaten early).
as I've gotten older my ability to consume fruit, onions, garlic and most dairy (and coffee :-( ) has been taken away from me. its really a miserable experience for someone that enjoys eating new and interesting things all the time.
I've eaten some hamburgers at Krystal's that definitely overtook whatever else was in front. Some folks have had the same or similar effect from White Castle, although I never have. Chipotle on occasion moves things along rather briskly too. No fruit or green leaves in any of them.
It may be that it's not a digestion thing, but some other factor they have that accelerates the process.
The study. It basically says that this is something one perhaps should consider in clinical settings and that the speed of fecal matter might be a worthwhile direction for future inquiry.
"Altogether, a better understanding of the complex, bidirectional interactions between the gut microbiota and transit time is required to better understand gut microbiome variations in health and disease."
It does not say 'this is a sign of health and that is not'.
The goal is more than 13 plants a day and your movement will be very consistent
You gotta lay down a fermentation base.
nobody dumps during their first two days of boot camp
> By considering interindividual and intraindividual differences in transit time in human studies, diet–microbiota interactions and disease-related microbiome signatures may be better elucidated.
