Exploring the evidence connecting soil biology, farming practice, and human nutrition — drawn from 3,000+ peer-reviewed studies.
Our 51-page white paper synthesises over 3,000 peer-reviewed studies into a practical framework for the UK food system. Four-layer Living System analysis: The Reality, The System, The Evidence, and The Invitation.

Healthy, biologically active soil produces more nutrient-dense food. Antioxidant levels can vary up to 200-fold within the same crop type depending on how it is grown.

96% of UK adults fail to meet fibre intake recommendations. Diet-related chronic disease costs £268bn per year — 92% of total NHS spend. The upstream solution is food quality.

69% higher polyphenols in organically grown crops. Farming practice — not certification labels — is the key determinant of nutritional density.

The current food system rewards volume over quality. No credible framework exists to measure, verify, and reward nutrient-dense production at farm level.
Read moreHealthy, biologically active soil produces more nutrient-dense food. The science is clear: soil microbial diversity, organic matter content, and mineral availability all directly influence the vitamin, mineral, and polyphenol content of crops.
Diet-related chronic disease is the defining public health crisis of our time. The UK faces both a quantity challenge and a quality challenge: people are not eating enough of the right foods, and the food available is less nutrient-dense than it should be.
Regenerative agriculture encompasses farming practices that restore and enhance soil health, biodiversity, and ecosystem function: minimal tillage, cover cropping, diverse rotations, and integrated livestock. Vitagri's evidence review shows that soil biology — shaped by these practices — is the primary determinant of nutritional density in food.
The current UK food system rewards volume over quality. No credible framework exists to measure, verify, and reward nutrient-dense food production at farm level. Price signals do not capture nutritional value, so farmers have no market incentive to optimise for nutrition.
Vitagri is building the infrastructure to fix this. By creating trusted measurement protocols, verification pathways, and market signals, we can reconnect farming, nutrition, and human health.
The Growing Health white paper synthesises evidence from over 3,000 peer-reviewed studies, selected using a PRISMA systematic review methodology. These span soil science, agronomy, nutritional biochemistry, epidemiology, and food policy. All 150 primary citations are available in the full reference list.
Long-term data from the McCance & Widdowson food composition tables — comparing 1940 and 2002 values — shows declines of up to 76% in key minerals including iron, magnesium, copper, and zinc in commonly consumed vegetables. These declines correlate with changes in soil management practice, varietal selection, and soil organic matter loss. See the soil and nutrient density research page for detailed evidence.
The evidence is strongly directional: farming practices that improve soil biological activity — cover cropping, reduced tillage, diverse rotations, reduced synthetic inputs — consistently correlate with higher crop nutritional quality. However, the relationship is complex and farm-specific. The GroundUp Framework is designed precisely to measure and verify these outcomes at farm level, moving beyond broad associations to traceable production-linked data.
