What Does “Nutrient Dense” Really Mean?
For decades, farmers and consumers have intuitively known that healthy soil grows healthy food — but we’ve lacked the tools to define, measure, and prove it.
Now, a new movement is changing that.
Join Dan Kittredge, founder of the Bionutrient Institute, for a groundbreaking discussion on the science, vision, and global initiative behind defining nutrient density — the measurable link between soil health, food quality, and human well-being.
This live webinar will explore how the Bionutrient Institute’s Nutrient Density Treaty seeks to create a 1–100 scale of food quality, empowering everyone — from growers to eaters — to see and value nutrition in a whole new way.


Dan has been an organic farmer for more than 30 years. He grew up on Many Hands Organic Farm in central Massachusetts with his parents, Julie Rawson, NOFA-MA Executive Director, and Jack Kittredge, publisher of Natural Farmer. After working globally in the late 90s and early 2000s with farmers, NGOs, and researchers across India, Russia, and Central America, Dan returned to the U.S. and in 2010 launched the BFA in order to ignite a movement around food quality.
Dan has become one of the leading proponents of “nutrient density,” and works to demonstrate the connections between soil health, plant health, and human health through workshops and speaking engagements around the world, the annual Soil and Nutrition Conference, and an increased presence online through social media, a YouTube channel, and numerous webinars and podcasts.
Dan launched the Real Food Campaign, now the Bionutrient Institute, that, with open-source science partners Our-Sci and FarmOS, are leading the effort to identify and increase nutrition in the food supply. The Bionutrient Institute has engineered and released a hand-held consumer spectrometer, the Bionutrient Meter, designed to test nutrient density at the point of purchase and bring transparency to the marketplace. Via the Bionutrient Meter, the goal is to empower consumers to choose their foods based on nutrient quality and thereby leverage economic incentives to drive full system regeneration.
