There are all sorts of misconceptions about coffee — that it dehydrates you, that it’s bad for your heart, or that caffeine is the only thing happening in the cup.
Dr. Riley Kirk welcomes coffee scientist Dr. Steven Helschien, widely known as “Dr. Coffee,” for a fascinating conversation exploring the chemistry, health effects, and cultural significance of one of the world’s most widely consumed psychoactive plants: coffee. With a background in chemistry and extensive experience in coffee education and research, Dr. Helschien breaks down the complex science behind coffee in a way that is both practical and accessible.
They discuss coffee as a psychoactive plant medicine, examining not only caffeine but also the wide range of entourage compounds that influence its physiological and cognitive effects.
Dr. Helschien and Dr. Kirk explore coffee’s relationship with inflammation, liver health, and cardiovascular markers, unpacking what current research suggests about coffee consumption and long-term wellness. They also explore the importance of coffee quality, including concerns about mold contamination, sourcing practices, and what consumers should look for when choosing high-quality beans. The conversation touches on brewing techniques and the science of extraction, the chemistry behind decaffeination methods, and why caffeine affects the body the way it does.
The episode also expands into broader discussions about coffee as plant medicine, the cultural role of caffeine, and the fine line between daily ritual and dependence.
Dr. Helschien shares insights into mold-free coffee sourcing, considerations around caffeine and breastfeeding, and practical strategies like caffeine cycling to maintain sensitivity to its effects.

Whether you're curious about caffeine’s effects, confused by common coffee myths, exploring brewing methods, or simply trying to get more out of your daily ritual, this episode offers science-backed insight in an accessible way.
