Dietary fiber
Intake model: one reported food record, food date unconfirmed. References: man aged 19–30. How to read the references.
No change indicated. Modeled fiber is substantial; no need to restore disliked beans or add fiber products.
Linked eating record; usual intake and clinical status unestablished · Reviewed 2026-10-10
Intake confidence: Moderate. Quantity confidence: Produce counts use generic weights; some portions assumed. Body status: Unassessed.
FDA values describe food labels.
Dietary fiber
46.1 g counted from food.
| Recommended intake | Upper reference | Food label reference |
|---|---|---|
| 38 g (AI) US National Academies · Total Fiber: dietary fiber plus qualifying functional fiber | Not established US National Academies · Food and oral supplements | 28 g (DV) FDA · Adults and children 4+ |
AI is a population planning reference, not a strict individual minimum.
Food contributions and uncertainty
Values are available for 13 of 13 recorded foods. 1 contribution(s) use an incomplete recipe or comparator. Product identity and portion assumptions still limit accuracy.
The saved portion/recipe scenarios span 45.4–46.7 g. This is a sensitivity range, not a confidence interval; uncertain food composition and unreported foods can fall outside it.

What fiber does and what its reference means
For men aged 19–30, fiber's AI is 38 g/day; no UL is established. Original fiber assessment, printed pp.339 and389.
See AI interpretation; the studies and tolerance discussion below address different fiber outcomes.
What human research supports
Reynolds and colleagues reviewed 185 prospective studies and 58 clinical trials. Higher-fiber diets were associated with better long-term disease outcomes in observational data; trials showed improvements in weight, systolic pressure and cholesterol. These are different kinds of evidence. Cohort associations do not prove the effect of adding one isolated fiber product, and the trial results do not establish prevention of every disease endpoint. Findings supported meaningful benefits around 25–29 g/day, with some dose-response evidence of further benefit; that is not a maximum or a command to keep raising intake. Reynolds et al.,2019
What the latest log suggests
The current model for my food log estimates 46 g, chiefly 12.3 g from four bananas, 11.1 g from raspberries and 10.1 g from avocado. Reported counts use generic edible weights; some produce portions and the complete can are assumed. The estimate is above the saved AI, but the narrow 45.4–46.7 g nut sensitivity range does not capture all fruit-size uncertainty. Eating date unconfirmed; report recorded October 10, 2026.
Attention: No change indicated for adding fiber. There is no basis for restoring a large serving of beans after it made the meal unpleasant and unfinishable. A different day with less fruit would deserve its own calculation, rather than automatically inheriting this figure.
Appetite and digestion are part of the outcome
Food bulk can be useful, but also competes with the ability to finish meals. Spread the preferred fruit and yogurt through the day. If fullness becomes excessive, swap or reduce a portion instead of adding another nutrient-dense food on top. If fiber intake changes markedly, increase gradually and observe bowel comfort and fluids; no universal maximum follows from absence of a UL. Large fiber-rich portions immediately before training may be uncomfortable for some people, so timing is a practical tolerance choice.
The log does not yet establish constipation, bloating or a microbiome problem. Do not interpret fermentation mechanisms or a commercial microbiome test as proof that another supplement is needed. The immediate question is whether the already fiber-rich pattern remains pleasant and repeatable.
