Podcast Highlight: Nutrient Density Decline and How to Fix It

Last Updated on June 6, 2021 by Colleen

Put on your hiking shoes listen to our latest favorite podcast interview.

Dan Kittridge has been farming organically for over 30 years. In this conversation, he talks to Dr. Mark Hyman, MD about how the increase in malnutrition and disease in industrialized countries is linked to the decline in nutrient density of our food.

And, if you grow your food in symbiosis with nature, not only does it taste better, but you do not need to regularly apply pesticides.

In addition, Kittridge explains his nonprofit’s work to develop a spectrometer that consumers can use to measure nutrient density in fruit and vegetables before they buy them.

Why We Love This

We love his approach–empowering consumers with transparency on how their food is grown and its healthfulness. Armed with that information, we can all advocate for better food and higher nutrient density through our everyday purchasing choices. Better still, we can use the information to reach out to companies we love and ask them to do better.

At ZEGO, we look to pesticide and heavy metal testing because of their own inherent value, of course. But we also look to it as a proxy for nutrient density. Kittridge flips this. His primary goal is to create more nutrient-dense food. And he asserts that foods grown in symbiosis with nature have a natural resistance to insects and invading plants. In turn, this means farmers will not need to use industrial chemicals on the crops.

Organic Foods Have Higher Phenol Nutrient Density

Meta analysis have not shown consistent and conclusive evidence that organic produce has higher vitamin content than conventional. But in 2014 scientists Baranski et al published a meta-analysis of 343 peer-reviewed studies shows strong evidence that antioxidants are significantly higher in organic food than in conventional (see list below). And, as Kittridge and Hyman discuss in the podcast, these compounds are most likely the plant’s flavor drivers.

Also of note, the same analysis revealed that cadmium is generally higher in conventional foods as well. Why you may ask? Well, the study authors suggest that is likely due to the fertilizers used on conventional crops.
