Fiber, insoluble
Today
3-day window. Water-soluble and not stored, so a short run of days is the signal.
None of today's foods carried a value for Fiber, insoluble. That is a gap in the data, not a reading of zero.
What it is
The bulking fraction — what actually moves the bowel.
Intake context
Not a target.
- Typical intake
- 11 g/dayNHANES, US adults — approximate, pending verification against the source tables
No separate reference intake exists; only total fibre carries one. Worth knowing which fraction you are getting, though: insoluble wheat bran is effective for constipation and commonly makes IBS symptoms worse, while soluble fibre tends to do the opposite.
Full write-up not finished
The reference intake above is real and cited — Fiber, insoluble is assessed against it exactly like any other nutrient. What is missing is the written panel: what it does in detail, what deficiency and excess look like, absorption, interactions, and food sources ranked against what you eat.
