This week on My Allergist Dad, we’re joined by entrepreneur and banana bread founder Allie Chernick, a former patient of Dr. Z who’s lived the confusing reality of food allergies firsthand. From positive allergy tests that don’t always match real allergic reactions to oral allergy syndrome, nut allergies, cross-reactivity, and food sensitivities, this episode breaks down why diagnosing and managing food allergies is rarely simple.

We explore:

· The difference between true IgE-mediated food allergies and food sensitivities

· Why allergy testing can show a positive result without real-world symptoms

· How oral allergy syndrome causes reactions to raw fruits, vegetables, and nuts

· Why someone might tolerate Nutella but react to hazelnuts

· How puberty, hormones, and environmental exposure can change allergy risk over time

· The everyday impact of living with food allergies, including restaurant anxiety and label reading

· What it’s like running a food business while managing common allergens

Dr. Z also shares insight into modern food allergy testing, the difference between sensitization and true allergy, and the latest advances in oral immunotherapy, desensitization treatment, and evidence-based allergy care that are helping patients manage peanut allergies, tree nut allergies, and other common food triggers more confidently.

If you’ve ever wondered whether you’re truly allergic to a food, outgrew a childhood allergy, tested positive without symptoms, or react inconsistently to certain foods, this episode offers clarity from both a medical and real-world perspective.

All that and more on this week’s episode of My Allergist Dad.

What if everyday exposures—from food to skincare to environmental chemicals—are quietly fueling allergies and inflammation through “environmental estrogen”?

In this episode of My Allergist Dad, Dr. Z and Drew talk with integrative immunology expert Dr. Benoit Tano about the estrogen-free lifestyle and how reducing estrogen-like exposures may help calm allergic and inflammatory symptoms.

They discuss how environmental chemicals, pesticides, plastics, and even personal care products can mimic estrogen in the body, potentially overstimulating immune cells and contributing to hives, mast cell activation, fatigue, and chronic inflammation. Dr. Tano explains why women may be especially affected, how hormone imbalance intersects with allergy pathways, and what practical changes he recommends to lower exposure.

If you’re dealing with unexplained allergies, chronic hives, or inflammation—and wondering whether hormones or the environment could be part of the picture—this conversation explores the estrogen-free approach and its potential role in immune health."

If running makes you wheeze, should you stop exercising… or do you actually need it more?

In this episode of My Allergist Dad, Drew and Dr. Z break down the real relationship between exercise and asthma — including why exercise doesn’t cause asthma, how it can act as a trigger, and what’s really going on inside your airways when you start wheezing. They talk through exercise-induced asthma, allergic inflammation, cold and dry air, pollution, and why swimming often feels easier than running.

You’ll also learn why treating your allergic triggers can raise your exercise tolerance, how pre-treating with inhalers actually works, and why frequent workouts can mean fewer asthma symptoms over time — not more.. Plus: breathing techniques, humid air hacks, and why the answer is almost always don’t skip the gym.
