Genistein attenuates ovalbumin-induced food allergy in mice: intestinal barrier, gut microbiota, and metabolites

Genistein pretreatment reduced experimental food allergy signs in mice, with associated changes in gut microbiota and fecal metabolites.

What the study showed

In an ovalbumin-induced murine food allergy model, genistein administered before and during sensitization attenuated clinical symptom scores, specific antibody responses, mast cell activation, and rectal temperature decline. The treatment was associated with preservation of jejunal tight-junction markers, T-cell modulation, and increased fecal butyrate. Correlation analyses suggested associations between microbial taxa, metabolites, and immune parameters.

How it was done

Murine ovalbumin food allergy model; assessments included immunology, histology, gut microbiome, short-chain fatty acids, and fecal metabolomics. In vitro experiments with bone marrow-derived dendritic cells complemented in vivo findings.

Risk of bias

This is a preclinical mouse study; translation to humans is speculative. The abstract does not detail dose, exact duration, number of animals per group, or controls for genistein's hormonal confounders.

Interpretation limit

What this study does NOT prove

The study does not demonstrate efficacy, safety, or causal mechanism in humans with food allergy.

In clinical practice

Results do not support any clinical or nutritional recommendation of genistein for food allergy prevention in humans. The preclinical stage requires replication and safety studies before any application.

Limitations

This is a preclinical mouse study; translation to humans is speculative. The abstract does not detail dose, exact duration, number of animals per group, or controls for genistein's hormonal confounders.
