Vitagri is working with the Bionutrient Institute to accelerate the measurement of farming for nutritional density.
Why this matters for Pulse — the Bionutrient Institute's crop sampling reaches the same conclusion Vitagri's evidence base reaches independently from the soil and agronomy literature: nutritional spread within a crop is wider than between varieties. It is corroborating evidence for grading food at farm level — not an input to Pulse Brain or the Predictive Model.
Vitagri and the Bionutrient Institute share a founding premise: that the nutritional quality of food can be measured, and that measurement — not labels — is what will change how food is grown. This page sets out who the Institute is, what their data shows, and where it aligns with Vitagri's own measurement work.
The Bionutrient Institute is the world's leading research organisation on the relationship between soil biology, farming practice, and food nutritional quality. Its founder and executive director, Dan Kittredge, is a long-standing voice in the regenerative-agriculture movement and a pioneer of the idea that the nutritional value of food is variable, measurable, and a function of how it is grown.
The Institute runs an open crop-survey programme — collecting and analysing thousands of food samples to build one of the largest public datasets on nutritional variation in food. Its work is published openly at bionutrientinstitute.org.
The Bionutrient Institute's crop data from 2018 to 2020 shows something that reframes the food-quality conversation entirely: the spread of nutritional density within a single crop type is far wider than the difference between varieties. Two carrots of the same variety can differ in nutritional content more than two different varieties grown the same way.
The implication is direct. If nutritional quality varies that much within a crop, then the variety on the label tells you very little. What tells you more is how and where that specific food was grown — the soil it came from, the biology in that soil, the practices of the farmer who grew it. This is the same conclusion Vitagri's evidence base reaches from the soil and agronomy literature, arrived at independently from sampling real food.
“We, at the Bionutrient Institute, are delighted to be working with Vitagri to accelerate the measurement farming for increasing nutritional density.”
Vitagri and the Bionutrient Institute are working together to accelerate the measurement of farming for nutritional density, as Dan Kittredge's note above reflects. Both organisations start from the same conviction: that nutritional quality is variable, measurable, and a function of how food is grown.
The detailed scope of the working relationship is being finalised, and this page will be updated as it develops. For now, the Institute's published crop data stands as independent corroboration of the case Vitagri's evidence base makes from the soil and agronomy literature.
Vitagri's GroundUp Framework measures practice and outcome at farm level rather than relying on labels or variety — the same conclusion the Bionutrient Institute's crop data points to independently. Explore the full GroundUp Framework →
The Bionutrient Institute is a research organisation studying the relationship between soil biology, farming practice, and food nutritional quality. Its founder, Dan Kittredge, is a long-standing voice in the regenerative-agriculture movement. Its crop-survey programme has built one of the largest open datasets on nutritional variation in food.
Bionutrient Institute crop data from 2018 to 2020 shows that the spread of nutritional density within a single crop type is far wider than the difference between varieties. In other words, how and where a food is grown matters more for its nutritional quality than which variety it is — the central premise behind measuring food at farm level.
Vitagri and the Bionutrient Institute are working together to accelerate the measurement of farming for nutritional density, as Dan Kittredge's note reflects. The detailed scope of the working relationship is being finalised. The Institute's published crop data independently corroborates the case Vitagri's evidence base makes from the research literature.
The GroundUp Framework translates this evidence into a practical measurement, verification, and certification system for nutrient-dense food production in the UK.
