Freeze-dried whole doenjang,
does it really help with Reduction in visceral fat?
research showsThe grade is C with 54 points. A 12-week trial randomized 60 adults and analyzed 51; 9.9 g/day freeze-dried doenjang reduced CT visceral fat by about 7.9 cm² more than control. The reported standard error gives an approximate 95% confidence interval of 0.5 to 15.3 cm² and a standardized difference near 0.60, but this was an imaging marker in one small completer analysis.
ads claimCalling doenjang only a longevity or fat-loss food hides an important half of the picture. This trial showed a visceral-fat signal, while its 40 g fresh equivalent contained 3.8 g salt, about 1,495 mg sodium or 75% of the daily value.
Useful facts when choosing a product
- The paper reported 3.8 g salt per 40 g fresh equivalent of the trial product, converting to about 1,495 mg sodium or 75% of a 2,000 mg daily value. Separately, the 10% to 13% salinity range for traditional doenjang generally gives a background range of about 1,572 to 2,044 mg sodium, or 79% to 102%, per 40 g.
- Shukla et al. reported mean histamine of about 268 mg/kg and mean tyramine of about 1,267 mg/kg across 23 traditional doenjang samples. These were not assays of the trial product; products vary, and people taking monoamine-oxidase inhibitors need particular caution with tyramine.
- Nitrite and N-nitroso compounds in the trial product were not confirmed.
- Records of East Asian fermented pastes are old, but they cannot automatically be treated as records of the same product as modern Korean doenjang.
- A visceral-fat reduction and potentially high sodium exposure can both be true because they are different claims.

What the research actually shows
The tables in Cha YS et al. 2012 were checked directly. Twelve-week visceral-fat change was −8.6 cm² with doenjang and about −0.6 cm² with placebo, and the between-group standard error was 3.7 cm². Conversion using a t distribution with about 49 degrees of freedom gives an approximate confidence interval of 0.5 to 15.3 cm². The covariance of change was unavailable, but the public table allowed direction and approximate standardized magnitude to be calculated.
Why this is classified as C (54)
The calculable effect reached a conventional medium magnitude, but CT visceral fat is an imaging marker rather than a clinical event. Evidence is one small trial analyzing 51 completers without a confirmed preregistration, yielding C with 54 points.
Counterpoint. The publicly funded positive signal merits follow-up, but independent replication including lower-sodium products and long-term clinical outcomes is needed.
Rejudgment record. Cross-check applied — Direct review of group CT changes and standard error, approximate confidence-interval and standardized-effect calculations, and cross-checking of composition studies
| 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+ | Meets the clinically important 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 |
|---|---|---|
| Freeze-dried whole doenjang reduces CT visceral fat | C | One small completer analysis found a conventionally medium difference. |
| About 40 g fresh doenjang can approach a daily sodium value at traditional salinity | C | This follows from composition ranges and calculation and is separate from efficacy. |
