Ground sesame seeds 40 g/day,
does it really help with Improved knee osteoarthritis pain and function?
research showsThe grade is C with 40 points. In a 50-person trial, both groups received acetaminophen and glucosamine, while only the sesame group added 40 g/day of ground sesame for two months. Between-group tests favored sesame for pain VAS, KOOS, and TUG with P values of 0.004, 0.009, and 0.002. The paper reported pain scores as medians and interquartile ranges, so a mean-based effect-size conversion could not be used.

Useful facts when choosing a product
- The test food was washed, dried sesame ground to improve digestion and absorption and packed in 40 g portions.
- A representative value for dried whole sesame is about 573 kcal per 100 g, making 40 g about 229 kcal. A direct caloric assay of the trial product was not confirmed.
- Sesame is a major food allergen designated by the US FDA.
- The identity of the classical term Huma varies between sesame and flax across texts, so a classical match for this verdict is unconfirmed.
- Verdict 258 is C with 44 points for isolated sesamin and lipid, blood-pressure, and liver outcomes; verdict 1300 is ? for black sesame and sesamin in hair loss. Verdict 226 is C with 43 points for pumpkin-seed oil, and verdict 062 is A with 84 points for psyllium husk. Their forms and outcomes differ from ground whole sesame for knee symptoms.
What the research actually shows
The 2013 peer-reviewed paper by Eftekhar Sadat B et al. and a public report using the same registration were cross-checked. IRCT201011164105N4 was confirmed, but the original start-date record was not obtained, so prospective registration remains unconfirmed. A related protocol powered the sample for total cholesterol, leaving the original primary status of pain and function unclear. Tabriz University of Medical Sciences provided university research support; commercial funding was not confirmed.
Why this is classified as C (40)
A peer-reviewed trial reported positive tests, but magnitude was not calculable and the evidence is one 50-person, two-month, non-placebo trial, yielding C with 40 points.
Counterpoint. A sufficiently powered independent trial should publish the full outcome table and prespecified plan and use a food placebo with blinded assessment.
Rejudgment record. Cross-check applied — Cross-checked the 2013 paper abstract, a public report under the same registration, and FDA allergen material for analyzed sample, background treatment, food form, P values, and reporting limits
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | EX | The clinical size of the effect could not be judged |
| Precision | CX | No pooled confidence interval could be confirmed |
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 |
|---|---|---|
| Adding 40 g/day of ground sesame to standard treatment improves knee pain and function | C | One small short trial was positive, but magnitude was not verifiable. |
| Sesame is a major food allergen | ? | This is an established safety and regulatory fact, not a graded efficacy outcome. |

Evidence Table
| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Randomized parallel trial of standard therapy versus standard therapy plus ground sesame | 2 | University research support from Tabriz University of Medical Sciences; commercial funding unconfirmed | Pain VAS, KOOS, and TUG | Between-group P=0.004, 0.009, and 0.002; median and interquartile-range pain reporting precluded a mean-based effect-size conversion | Peer-reviewed but small, short add-on trial |
