Data Sheet 1_Health benefits of fermented foods: a strategic roadmap from the PIMENTO initiative.pdf

Across these reviews, fermented foods were associated with generally modest, and sometimes neutral, effects on diverse health outcomes. The collective evidence also highlighted recurring strengths of the field, including biological plausibility, broad health relevance, and promising functional targets for selected fermented food categories, alongside persistent challenges related to food characterisation, study heterogeneity, dose–response assessment, mechanistic validation, and long-term human evidence.

Safety findings were broadly reassuring in the populations studied, although reporting was inconsistent. We translate these findings into a strategic roadmap for research and policy, reflecting the expert judgement of the author panel rather than a formal consensus procedure, organised across short-, medium-, and long-term horizons, to harmonise fermented food definitions and exposure assessment, standardise product dossiers and analytical methods, strengthen trial design, incorporate mechanistic validation, and align evidence generation with regulatory and public health needs while remaining relevant to diverse stakeholders.

Overall, this work provides a structured foundation for the next phase of fermented food research by identifying evidence gaps, methodological priorities, and policy needs required to advance the field toward greater scientific and regulatory maturity. To our knowledge, this represents the first effort of its kind to consolidate evidence and knowledge gaps across the full breadth of fermented foods research into a single, actionable strategic framework.</p>
