My guest today is Dan Kittredge, who knows more about what makes food nutritious than anyone I know.  Dan Kittredge has been an organic farmer for more than 30 years and is the founder and executive director of the Bionutrient Food Association (BFA), a non-profit whose mission is to “increase quality in the food supply.”  Known as one of the leading proponents of “nutrient density,” Dan works to demonstrate the connections between soil health, plant health, and human health. Out of these efforts was born the Bionutrient Institute, which has engineered a prototype of a hand-held consumer spectrometer, designed to test nutrient density at point of picking or purchase.  He has decades of experience literally testing growing methods and measuring the nutrient density both in plants and livestock. As people extol the benefits of organic, zero-dig, regenerative farming and the harms of our herbicide and pesticides laden food supply, Dan has actually been measuring and working out what farmers and growers have to do to get the healthiest soil for the healthiest plants. Not only am I honoured to have Dan as my podcast guest but also he’s coming to our farm in the Black Mountains in June to teach us, and others, how to grow super-nutritious food.
