Nutrient density with Dan Kittredge
In this episode of the Regenerative Healthcare Podcast, we spoke with Dan Kittredge, founder of the Bionutrient Food Association and a pioneer in the field of nutrient density. For nearly two decades, Dan has been working on the relationships among soil health, plant health, and human health, and on how to measure food quality more directly.
Not all food of the same type has the same nutritional value
A key point from the conversation was that one carrot is not the same as another carrot. Dan explained that food can vary greatly in nutrient content depending on how and where it was grown. This is where the distinction between nutrient density and nutrient variation becomes important.
Nutrient density refers to the nutritional quality of food. Nutrient variation refers to the fact that foods of the same type can differ significantly in that quality.
Soil life matters
Dan shared that, in the Bionutrient Food Association's research, the strongest indicator of higher food quality was not simply whether produce was labelled local, organic, or regenerative, but rather the biological activity in the soil.
This adds an important layer to the discussion around food quality. Labels still matter, especially for building a healthier and more resilient food system, but they do not automatically tell us everything about the nutritional quality of what we eat. Soil health matters deeply, too.
Why this matters for food choice and health
We also discussed what this could mean in practice. If foods of the same type differ significantly in nutritional value, then food quality becomes a much more practical question for consumers, farmers, and healthcare systems alike.
Dan also stressed the connection between flavour and nutrition: food that is richer in nutrients should also taste better. That makes nutrient density relevant not only to science and farming but also to how people actually choose, cook, and enjoy food.
For us, this conversation showed that if food is to become a real part of prevention and care, then the nutritional quality of that food deserves much more attention.
Mission
Our mission is to share the best practices of pioneers from around the world who have successfully connected local regenerative and organic farmers with the public, communities, and health institutions.
