Fig paste, 300 g daily,
does it really help with Improved colonic transit and bowel symptoms in functional constipation?
research showsThe verdict is C with 48 points. In an 80-person randomized trial completed by 74, fig paste shortened eight-week colonic transit more than a sugar-and-starch placebo and improved some symptoms. A standardized difference calculated from the primary-outcome change scores was about 0.47, just below the conventional medium effect of 0.5.
ads claimFiber descriptions become claims that figs treat constipation. This study used 300 g of paste daily, not a few fresh figs, and the placebo did not match fiber.
Useful facts when choosing a product
- Figs contain dietary fiber, and fiber can affect stool bulk, water, and transit.
- The placebo contained water, sugar, and modified starch and did not match the paste's fiber. Fig-specific components and added fiber therefore remain confounded.
- Verdict 532 is C with 55 points for green kiwifruit powder in the same indication, but it is a different food and form.
What the research actually shows
Baek and colleagues compared 300 g daily of fig paste with a water, sugar, and modified-starch placebo for eight weeks. NCT02138851 registered colonic transit as primary, matching the positive paper. The trial began in June 2013 and was registered in May 2014, making the retrospective-registration interval longer. Korea Food Research Institute investigators participated, while no direct grower or food-company funding was identified in public information.
Why this is classified as C (48)
The registered surrogate primary outcome was positive, but this was one small eight-week trial and the standardized effect of about 0.47 missed the conventional medium threshold. The result is C with 48 points.
Counterpoint. Double blinding, placebo control, and very low attrition are strengths for a whole-food study.
Rejudgment record. Cross-check applied — Recalculated the standardized change-score difference and cross-checked the registered primary outcome, timing, placebo composition, and funding disclosure
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E~ | Statistically positive but below the threshold |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Figs contain fiber and fiber affects colonic transit | C | This is an established composition and physiology fact; the grade applies to the fig-paste claim. |
| Three hundred grams of fig paste improves functional constipation | C | Primary transit was positive, but magnitude was modest and added fiber was not isolated. |
