Connecting soil health and human health with Raiza Rezende
This episode looks at how do farm practices shape the nutritional quality of food—and what would it take to make that knowledge useful in the healthcare industry? Our guest is Raiza Rezende, co-founder of RHEA — Regenerative Healthcare European Association, an organisation working across education, research, and policy to connect agriculture and healthcare.
In this episode, you’ll hear:
- Why soil health and human health are linked. We discuss One Health—the idea that the health of soils, plants, animals, and people is interconnected, including via the microbiome.
- Bridging the gap between farms and healthcare. RHEA’s core mission is to connect the healthcare sector (doctors, hospitals, dietitians) with agriculture.
- Where the science stands. Nutrient density is a young field; evidence is building but uneven. We talk about running multi-year, outcome-based trials and why results should be read with nuance.
- How to measure “nutrient density” without hype. From lab panels to crop-specific benchmarks (tomatoes vs. tomatoes), and why sampling design matters more than slogans.
