Four gold kiwifruits daily equivalent,
does it really help with Shorter duration of cold symptoms?
research showsThe verdict is C with 46 points. Overall respiratory-infection incidence did not differ, while only some symptom durations were shorter among people who became ill. The sore-throat difference was conventionally large, whereas the head-congestion difference was small.
ads claimNutrients and antioxidants in gold kiwifruit can be expanded into a claim that it prevents colds or shortens every symptom. The trial did not reduce overall incidence and found positive results only for selected symptoms.
Useful facts when choosing a product
- The intervention combined two fresh gold kiwifruits with freeze-dried material equivalent to two more; it was not four fresh fruits.
- Banana was an active food comparator, not no treatment.
- Verdict 1167 is D with 31 points for sleep, while verdict 532 is C with 55 points for functional constipation; both address different outcomes.

What the research actually shows
Hunter and colleagues conducted the randomized crossover study from July to November 2008. Two nonadherent participants and three noncompleters were excluded. ZESPRI International Limited funded the work, and bananas were the active food comparator.
Why this is classified as C (46)
This was one manufacturer-funded, small, short trial using completer data and bananas as the comparator. Overall incidence did not differ, selected symptom subsets were positive, and the converted magnitudes differed by endpoint, yielding C with 46 points.
Counterpoint. The two selected symptom durations were statistically shorter, so the study was not wholly null.
Rejudgment record. Cross-check applied — Cross-checked overall incidence, symptom-specific denominators, comparator, funding, and effect-size reconstructability against the article
| Endpoint | P | Symptom or function itself is the target - including patient reports and performance tests |
| Replication | R1 | Single confirmatory trial |
| Independence | I0 | Evidence comes only from manufacturer studies |
| Effect size | E~ | Statistically positive but below the threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (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 |
|---|---|---|
| Gold kiwifruit contains vitamins and carotenoids | C | This is a composition fact separate from cold efficacy. |
| Four gold-kiwifruit equivalents daily shorten cold symptoms | C | Overall incidence was null and only symptom subsets were positive. |
