Spring is here, and seasonal pollen along with it! This week on Foodie Pharmacology, Dr. Cassandra Quave speaks with Gary Falcetano, PA-C, AE-C, Senior Manager of Global Medical & Scientific Affairs in Allergy at Thermo Fisher Scientific and a longtime clinician and educator in asthma and immunologic disorders, about pollen food allergy syndrome and why certain fresh foods can suddenly cause itching or irritation during allergy season.

Also known as oral allergy syndrome, this condition stems from cross-reactivity between pollen proteins and similar proteins found in plant foods. Gary explains how this immune mix-up happens, why symptoms are typically limited to the mouth and throat, and why something as simple as cooking an apple can make it more tolerable.

They also cover how common this syndrome is, why it is frequently overlooked, and how clinicians distinguish it from more serious food allergies using detailed history and targeted testing. The conversation highlights the role of IgE, component-resolved diagnostics, and the importance of understanding seasonal exposure. The episode closes with practical tips for managing symptoms, from reducing pollen exposure at home to simple food preparation strategies that can make a real difference during peak allergy season.

This Foodie Pharmacology podcast is part of a special two part series sponsored by Thermo Fisher Scientific Inc. The views and opinions in this podcast are those of the presenters and represent the synthesis of science.

What if the key to reducing food waste, strengthening community, and reconnecting with our food systems is already in your kitchen?

In this episode of Foodie Pharmacology, Dr. Cassandra Quave speaks with Dr. Julia Skinner, food writer, fermentation expert, and founder of the Culinary Curiosity School, to explore the practice of food preserving. From fermentation to freezing, Julia shares how preserving is not just a set of techniques but a way of thinking about food with intention and creativity.

They discuss her upcoming book, Essential Food Preserving, which takes an ingredient-first approach. Instead of rigid recipes, it asks a simple question: what can you do with what you have right now? That mindset opens the door to everything from fruit leathers and infused vinegars to fermented drinks and pantry staples built from scraps.

They also explore the deeper reasons preserving matters. These practices are rooted in food security, seasonality, and survival. Today, they offer a powerful way to reduce waste and reconnect with the sources of our food. Fermentation, in particular, plays an important role in building community. Sharing techniques, recipes, and traditions creates meaningful connections around food.

If you’ve ever felt intimidated by preserving, this episode offers an approachable place to begin. Start small, stay curious, and focus on practice rather than perfection. Essential Food Preserving will be released on May 19, 2026, and is available now for pre-orders!

Flowers may seem delicate, but they have transformed the planet! In this episode of Foodie Pharmacology, Dr. Cassandra Quave speaks with Dr. David George Haskell, author of the new book How Flowers Made Our World, about the revolutionary rise of flowering plants. They discuss how grasses helped shape human evolution as “grass apes,” why orchids rely on intimate fungal partnerships, and how floral chemistry communicates with pollinators through scent and even electrical fields! From the endosperm that feeds much of humanity to the cultural and aesthetic power of flowers, this conversation examines how flowering plants engineered ecosystems, nourished civilizations, and continue to shape our future.
