Gut-microbiota-targeted diets modulate human immune status
Open accessPublished version of a preprint
Abstract
Diet modulates the gut microbiome, which in turn can impact the immune system. Here, we determined how two microbiota-targeted dietary interventions, plant-based fiber and fermented foods, influence the human microbiome and immune system in healthy adults. Using a 17-week randomized, prospective study (n = 18/arm) combined with -omics measurements of microbiome and host, including extensive immune profiling, we found diet-specific effects. The high-fiber diet increased microbiome-encoded glycan-degrading carbohydrate active enzymes (CAZymes) despite stable microbial community diversity. Although cytokine response score (primary outcome) was unchanged, three distinct immunological trajectories in high-fiber consumers corresponded to baseline microbiota diversity. Alternatively, the high-fermented-food diet steadily increased microbiota diversity and decreased inflammatory markers. The data highlight how coupling dietary interventions to deep and longitudinal immune and microbiome profiling can provide individualized and population-wide insight. Fermented foods may be valuable in countering the decreased microbiome diversity and increased inflammation pervasive in industrialized society.

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Serum baseline is dated to a week without a blood collection
MinorThe metabolomics results place a serum sample at week −2, but the specimen schedule lists the pre-intervention blood collection at week −3 and no collection at week −2.
“Untargeted metabolomics on serum samples at baseline (week −2) and end of maintenance (week 10) was conducted using untargeted, high-throughput liquid chromatography-mass spectrometry (LC-MS).”
“Blood samples were collected at 7 time points: −3 weeks, start of intervention, week 4 (end of ramp-up), week 6, week 8, week 10 (3 time points during maximum intake), and week 14 (end of observation).”
Inflammation-panel analyte counts disagree
MinorThe results describe a panel of 93 measured proteins, while the serum-cytokine methods specify 92 analytes.
“we identified 19 of 93 cytokines, chemokines, and other inflammatory serum proteins that decreased over the fermented food intervention”
“Cytokine data were generated from serum samples submitted to Olink Proteomics for analysis using their provided inflammation panel assay of 92 analytes”
Stool carbohydrate measurement method changes between sections
MinorThe results say stool monosaccharides were measured by HPLC, but the corresponding methods describe GC-MS measurement.
“Carbohydrates were extracted from stool samples, acid-hydrolyzed to release monosaccharides, and then measured using HPLC.”
“Methods for measurement of monosaccharides present in stool samples using GC-MS are described in (DeJongh et al., 1969).”
Food-log frequency during ramp-up is inconsistent
MinorOne methods section says food logs were kept every other week throughout the study; another says they were kept every week during the ramp phase.
“They were asked to keep detailed food logs 3 days per week (2 weekdays and 1 weekend) every other week through the duration of the study.”
“Participants logged all their food and drink intake for 3 days (2 weekdays and 1 weekend) each week during the ramp phase and every other week for the rest of the study using the HealthWatch360 app.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-04, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-04 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
