While information about the connection between food, gut health, and our overall well-being has come into the spotlight in recent years, it can still often be something that only the privileged have time, money, and energy to devote to. Kimberley Wilson is hoping to change that.

She’s a psychologist with a degree in nutrition, and author of the books How to Build a Healthy Brain and Unprocessed: How the Food We Eat is Fueling our Mental Health Crisis. Wilson explains how deep the connection is between mental health and what we eat, how that shows up in our daily lives, and why these ideas matter for everyone.
