From practical actions to deep science — the only way to have the latest and most comprehensive evidence on what the farming and food industry can do to enhance human health.

How we tier evidence

1. T1
   Meta-analyses & systematic reviews

   The strongest synthesis of existing evidence. Pre-registered, protocol-led, PRISMA-compliant where possible.
2. T2
   Randomised controlled trials & large cohorts

   Experimental or longitudinal evidence with a control group or baseline. Strong internal validity for causal claims.
3. T3
   Observational studies & field trials

   Cross-sectional, case-control and on-farm field evidence. Useful for association but weaker causal claims.
4. T4
   Narrative reviews, commentaries & policy reports

   Editorial syntheses, guideline documents, industry white papers. Valuable context but lower formal evidence weight.

What makes Pulse Brain different

• Global in scope on soil-to-health evidence.

  The catalogue spans research from every region where soil-to-health evidence is published — over 14,500 curated records across international, UK, European, US, and Asian institutions. Not a UK-only archive.
• UK-contextualised interpretive layer.

  Every record is read by Vitagri’s research team and tagged with applicability notes for UK policy, farming systems and supply chains — the value-add that makes global research actionable for UK audiences, without limiting who can use it.
• Tier-graded T1–T4.

  Not all evidence is equal. Each record carries a T1–T4 grade derived from study type and design, so readers can weight claims accordingly.
• Cross-domain — farming, soil, nutrition, health.

  Most catalogues specialise in either agriculture or nutrition. Pulse Brain integrates farming systems, soil biology, nutrient density, food quality and human health in one register.
• Industry plus peer-reviewed sources.

  Alongside over 14,500 peer-reviewed studies, Pulse Brain includes approved industry reports, policy briefs and NGO research from 40+ trusted institutions worldwide.
• Weekly auto-ingest, manually reviewed.

  Weekly auto-ingest, manually reviewed: pulling new records from PubMed, CrossRef, OpenAlex, Semantic Scholar and trusted publisher feeds. Every record is reviewed before going live.
• Free, citable, machine-readable.

  Every record has a permanent URL and schema.org ScholarlyArticle markup. Academic API access is free globally.
