Dan Kittredge has farmed organically for 30+ years, and is the founder and executive director of the Bionutrient Food Association (BFA), whose mission is to “increase quality in the food supply”. As a leading proponent of “nutrient density”, Dan demonstrates the connections between soil health, plant health and human health. Out of these efforts was born the Real Food Campaign which has engineered a prototype of a hand-held citizen spectrometer designed to test nutrient density at point of purchase.
