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.
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.
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.
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'.
