Reading food labels can feel like a full-time job when you or your child has food allergies. Even when you know what to avoid, labels can still be confusing, especially when you run into “may contain” warnings.

Marion Groetch, a registered dietitian with decades of experience in food allergy care and education, joins us to unpack all things food labels. Together, we break down U.S. allergen labeling laws, what parts of the package actually matter, and why “may contain” statements are a much grayer area than most people realize. We also share practical tips for navigating so-called “mystery ingredients” like natural flavors and oils, when it is worth contacting a manufacturer, and how to avoid being more restrictive than necessary while still staying safe.

Clonal mast cell disease is often missed because symptoms vary from person to person, tryptase levels can be normal, and bone marrow biopsies are hard to get. For some people, unexplained or very severe anaphylaxis may be an early sign of a clonal mast cell disease.

In this episode, we review “Prevalence of KIT D816V in anaphylaxis or systemic mast cell activation,” published in October 2025 in the Journal of Allergy and Clinical Immunology. This paper, known as the PROSPECTOR trial, is looking at how often the KIT D816V mutation can be found using a blood test in adults who have had anaphylaxis or systemic mast cell activation symptoms.

We break down why KIT D816V matters, how it connects to systemic mastocytosis, why HaT needs to be considered, and how newer blood tests may help doctors catch clonal mast cell disease earlier.

Persistent congestion, pressure, or a reduced sense of smell often gets mistaken for allergies or a stubborn cold when it may be something more, like chronic rhinosinusitis with nasal polyps (CRSwNP). Getting the right diagnosis is the first step toward real relief.

Dr. Tonya Farmer, a board-certified ENT, joins Kortney and Dr. G to explain how chronic rhinosinusitis with nasal polyps (CRSwNP) is diagnosed. She walks us through the full evaluation: what symptoms matter, what a nasal endoscopy actually shows, when a CT scan is needed, and how type 2 inflammation fits into the picture.

Avoidance has long been the standard for managing food allergies. But new options, such as oral immunotherapy (OIT) and biologic medications like Xolair (omalizumab), are changing the landscape. With more choices available, many patients and parents are wondering how to start the conversation with their allergist and what questions to ask.

Kortney and Dr. Payel Gupta talk with Dr. Shahzad Mustafa, a board-certified allergist and immunologist, about how patients can navigate today’s food allergy treatments with confidence. Together, they explore what to consider before starting OIT or Xolair, how to set realistic expectations, and why strict avoidance is still the right choice for many families.

When it comes to keeping kids with food allergies safe at school, school nurses are often the quiet heroes behind the scenes. From managing allergy action plans and emergency responses to training teachers and organizing care for hundreds of students, their role is essential, but often misunderstood.

Kortney and Dr. Payel Gupta sit down with Elizabeth Elliott, a school nurse and President of the Maryland Association of School Health Nurses. Liz shares what really happens inside the health room and how school nurses coordinate care for students with food allergies and asthma. Plus, why communication between families and school staff is key to keeping kids safe.

After this episode, you’ll have a whole new appreciation for your school nurse and a better understanding of how to partner with them to make every school day safer for kids with allergies.

Mucus plugging is a challenge in asthma care. It’s thick, sticky mucus that blocks the airways and doesn’t respond to regular inhalers. Even when inflammation improves, these plugs can lower lung function, limit how well medicine works, and make asthma harder to control.

In this episode, we break down the study: “Effect of Dupilumab on Mucus Burden in Patients with Moderate-to-Severe Asthma,” published October 28, 2025. The analysis looks at whether dupilumab (Dupixent), a biologic that blocks IL-4 and IL-13, can lower mucus burden and improve lung function, especially in people who start with a high “mucus plug score.”

Living with constant congestion, facial pressure, or a loss of smell can make daily life exhausting. For many people, these symptoms are more than just allergies or a lingering cold. They may be signs of chronic rhinosinusitis with nasal polyps (CRSwNP).

Dr. Rohit Katial joins Kortney and Dr. G to unpack what CRSwNP really is, how it develops, and why type 2 inflammation plays such a key role. Together, they explain what’s happening inside the sinuses, what symptoms to look for, and when it’s time to see a specialist.

Navigating food allergies is tough enough, but adding family dynamics to the mix can make things even more complicated. When loved ones don’t understand you or your child’s allergies or dismiss the rules meant to keep them safe, it can lead to conflict, hurt feelings, and stress for everyone involved.

Kortney and Dr. Payel Gupta sit down with psychologist Dr. Amanda Whitehouse to talk about how families can find common ground when emotions run high. Together, they unpack what it means to stay regulated in difficult conversations, how to set healthy boundaries with family members, and why understanding different coping styles can help prevent conflict before it starts.

For decades, allergists have focused on blocking what happens outside the mast cell: histamine, IgE, and interleukins. But now, there’s a new way to stop allergic inflammation before it even starts: by targeting what happens inside the cell with BTK Inhibitors.

Dr. Payel Gupta and Kortney are joined by Dr. Matthew Giannetti to unpack what BTK actually does and why inhibiting it represents an exciting breakthrough in allergy and immunology. Together, they explore how BTK inhibitors work, why this inside-the-cell approach is different from anything before, and what it could mean for people living with chronic spontaneous urticaria (CSU).

Seeing your allergist on a screen instead of in the office might feel strange at first, but for many people with allergies, telehealth isn’t just convenient.  it’s effective.

In this episode, we sit down with telemedicine pioneer Dr. Jay Portnoy to explore how virtual allergy care works, what it can and can’t do, and how it’s helping patients get the care they need without the wait or the long drive.

Dr. Portnoy shares over two decades of experience leading allergy telemedicine programs in rural areas and explains how remote care has grown from a fringe idea into a standard part of allergy care. He and Dr. G also discuss the benefits for both patients and clinicians.

So how do you know when telehealth is enough and when it’s not?
