What if our future food security depended not on fields of grain, but on forests of trees? In this episode of Foodie Pharmacology, I sit down with Elspeth Hay, author of Feed Us with Trees: Nuts and the Future of Food and host of the Local Food Report on CAI NPR. Elspeth takes us on a journey through oak groves and chestnut stands to explore how nut-bearing trees once fed the world—and could again.

We unpack the ecological power of keystone species like oaks and the role of fire in maintaining these ancient foodscapes. Elspeth shares how acorns, hazelnuts, and chestnuts offer a compelling alternative to industrial crops—and how Indigenous foodways and land management practices hold the key to unlocking their full potential. From forgotten ancestral practices to the modern movement to rewild our diets and ecosystems, this episode is a hopeful call to reconnect with the trees that once sustained us.
