Evidence across the soil-to-health chain

Vitagri's thesis is a chain — soil to farming to food to human health. The catalogue holds directly on-point, peer-reviewed evidence at every link, including the strongest tier: systematic reviews and meta-analyses.

records on how soil drives the nutritional quality of crops · incl. 18 systematic reviews
60+
Regenerative farming → soil carbon
records on practice, soil carbon & organic matter · incl. 11 systematic reviews
170+
Food → micronutrient density
records on biofortification & nutrient enrichment · incl. 4 systematic reviews
210+
Diet → human health
records linking diet to chronic-disease prevention · incl. 27 systematic reviews

Frequently asked questions

How many studies are in Vitagri's Pulse Brain evidence base?

Pulse Brain holds 16,000+ curated, continuously-maintained peer-reviewed studies on the soil-to-health chain. Refreshed daily, and every record links to a source you can open.

How credible is the evidence in Pulse Brain?

Every record is tier-graded T1–T4 by study design, around 88% are peer-reviewed, 92% link to a DOI you can open, and records are checked against retraction notices. Roughly one in eight records is Tier 1–2 evidence — meta-analyses and randomised trials.

Does the evidence cover the whole soil-to-health chain?

Yes — there is directly on-point, peer-reviewed evidence at every link: 560+ records on soil and nutrient density, 60+ on regenerative farming and soil carbon, 170+ on micronutrient density in food, and 210+ linking diet to chronic-disease prevention — including systematic reviews at every link.
