Could organic farming and healthy soil transform human health?
A new movement is exploring how food production affects human health. Farmers, scientists and nutritionists are teaming up to study links between organic farming, soil health and wellbeing. Their focus includes how biodiverse soils and organic crops might influence conditions like diabetes and heart disease. In the Netherlands, a 'food pharmacy' scheme has been prescribing organic food boxes to type 2 diabetes patients. Early reports suggest some participants have seen health improvements, though formal studies are still lacking.
Research shows that healthy soils, rich in bacteria and fungi, help plants absorb nutrients and naturally resist pests. These same soils may also boost the nutritional value of crops. A study in the *British Journal of Nutrition* found that organically grown fruits and vegetables can contain up to 60% more polyphenols—powerful antioxidants—than non-organic versions. Polyphenols act like 'rocket fuel' for gut microbes, which in turn support immunity, digestion and vitamin production. Diets high in these compounds have been linked to lower risks of cancer, heart disease, type 2 diabetes and Alzheimer's. Yet while regenerative farming projects, such as Yeo Valley Organic and HarvestCare, improve soil health and biodiversity, no direct evidence yet ties them to better human health outcomes. Yeo Valley Organic is now working with the University of Exeter to examine whether organic dairy farming affects the nutritional quality of milk and cheese. Meanwhile, a report by the Food, Farming and Countryside Commission highlights the cost of poor diets: for every £1 spent on low-quality food, over £2 is later spent treating related health problems.
The alliance between farmers, researchers and health experts continues to grow. Their work aims to uncover whether organic, biodiverse farming could lead to healthier food—and healthier people. For now, the focus remains on gathering long-term data to support these potential benefits.
