For our Valentine’s Day episode, I speak with Polish ethnobotanist and foraging expert, Dr. Łukasz Łuczaj about how humans connect to nature! Łukasz shares his work on wild foods—including plants, mushroom, and insects—and how this ties into cultural histories of the people who consume them. In addition to the edible aspects of the wild, we discuss Łukasz’s new book Sex in Nature: A Guide to Making Love in the Forests and Meadows to learn about the many other ways people connect with the outdoors!

Nutrimetabolomics is an emerging field of science that represents the intersection of metabolomics and nutrition research. Using the powerful tools of mass spectrometry and models with germ-free mice and human microbiome samples, scientists are discovering new biomarkers of health and are able to track how different foods are metabolized by the body and the gut microbiome. Our guest this week is Dr. Nichole Reisdorph; she’s working at the forefront of this exciting field to investigate how the consumption of everything from salmon to green tea, and even cannabis, impacts our metabolome.

In that magical period between winter and spring in the northeast US and Canada, tapped sugar maples yield buckets of clear sap. Once concentrated, the resulting sticky syrup is used as a natural sweetener for everything from breakfast treats to specialty cocktails. While sucrose does make up the majority of maple syrup, there are many other secondary metabolites present that give maple its unique flavor and contribute to its pharmacological potential. I speak with Dr. Navindra Seeram, an expert in the chemistry and pharmacology of maple trees. He explains maple chemistry and shares some fascinating projects underway in the development of nutraceutical and cosmeceutical products developed from maple.

Dead plants do tell tales. Over the past five hundred years, plant hunters have scoured the Earth, collecting millions of specimens that are now held in vast collections in New York, London and Paris, complemented by smaller collections found in museums and universities across the globe. These plants were sought out not just for their beauty and diversity, but also for their potential applications in new foods, medicines, and more. I speak with Dr. Barbara Thiers, Director of the Steere Herbarium at New York Botanical Gardens and author of a new book entitled, “Herbarium: The Quest to Preserve and Classify the World’s Plants.” We discuss the fascinating history of herbaria and recount the adventurous stories of some of the famous explorers that built these collections.

A vast network of fungi circles the globe—interwoven throughout the soil, coating surfaces above ground and even living inside of plants! There is an astonishing level of diversity among fungi, and this biodiversity is coupled with incredible chemical diversity. In this episode of Foodie Pharmacognosy, our guest is Dr. Nick Oberlies, an expert in the field of pharmacognosy who specializes in the study of fungal chemistry! He explains how he and his team find fungi growing inside plants and throughout the environment in the hunt for new molecules to treat cancer, infections, and more.

Plants produce a fantastic array of metabolites to defend themselves, communicate with other organisms in their environment, and attract pollinators and seed dispersers; sometimes, these metabolites can also impact human health. Our guest this week is Dr. Nadja Cech, an expert in the field of mass spectrometry and natural products. She explains how she uses this exciting tool of science to study the medical potential of herbs like kratom, goldenseal, and more. We also discuss the importance of mentorship and support of diversity and inclusion in science.

This week, we take a closer look at the plants and agricultural traditions of Oman, situated on the Arabian Peninsula. Our guest is Dr. Darach Lupton—an ethnobotanist who manages the collection and documentation of plants and seeds from across Oman in his role at the Oman Botanic Garden! He gives us a sneak peek behind the scenes of this incredible garden, which uniquely showcases native plants of the region in a variety of specialized habitats and biomes.

This week on the show, we’re going to dive into a really cool program dedicated to biocultural education and research in the Caribbean! Our guest is Dr. Sonia Peter. She is the Director of the Biocultural Education and Research program in Barbados and the founding director of Heritage Teas Barbados. We discuss ongoing initiatives dedicated to recapturing the biocultural heritage of the island and also sharing connections to traditional knowledge through a special line of heritage teas.

“Gene bank” may sound like something out of a Sci-fi movie – but they are actually really important in the real world! Gene banks are a type of biological repository where genetic material is stored. When it comes to crops, gene banks hold the future of food, and include seeds, plant cuttings and more. Join Dr. Quave this week as she chats with Dr. Ren Wang, the Director General of the China National GeneBank, based in Shenzhen, China.

I speak with Dr. Tinde van Andel, an ethnobotanist that studies the traditional uses of crops and medicinal plants from Africa to South America. She shares the incredible story of how enslaved African women hid special rice varieties and other crop seeds in their hair braids in their escape from plantations to the forest, where thriving Maroon communities were established and persist today in Suriname. Prof. van Andel explains how her team and collaborators used interdisciplinary tools from the examination of historic records, herbarium samples, ethnobotanical interviews and genomics approaches to unravel this fascinating history of this important African crop.
