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.

Can you be allergic to your own hormones?

In this episode of My Allergist Dad, Drew and Dr. Z dig into why so many people—especially women—start developing hives, food sensitivities, and new immune reactions in their 30s and 40s.

They break down how hormone shifts, estrogen dominance, autoimmune conditions like Hashimoto’s, and even “clean” products can push the immune system into overdrive. Dr. Z explains why many food reactions don’t show up on standard allergy tests, how mast cells respond to hormonal changes, and why inflammation—not the food itself—is often the real trigger.

You’ll also hear real patient stories, including how someone became reactive to their dish soap after avoiding previous allergens—and why adult-onset allergies are rarely random.

If you’ve ever asked:

• “Why am I suddenly reacting to foods I used to tolerate?”

• “Is this autoimmune, hormonal, or actually an allergy?”

• “Can hormone balance change how sensitive I am?”

This episode connects the dots—and helps you stop blaming yourself (or your dinner).

Seasonal allergies don’t have to feel like a surprise attack every year. In this episode of My Allergist Dad, Drew and Dr. Z break down how allergies actually work — and more importantly, how to get ahead of them before pollen, dust mites, and mold take over your life.

They cover why dust mites are a year-round problem with a seasonal growth phase, how indoor humidity quietly makes symptoms worse, and the biggest mistakes people make when “cleaning for allergies.” Dr. Z also explains why timing matters — from when to start nasal sprays and antihistamines to how preseason allergy drops and shots can reduce symptoms before your season even starts.

Plus, they dig into some wild real-world cases involving exercise, mold exposure, and allergic reactions that weren’t caused by food at all — and how lifestyle factors like sleep, stress, and diet can affect how intense your allergies feel.

If you’ve ever wondered:

• Why your allergies feel worse some years than others

• Whether air purifiers actually help with dust mites

• How to prevent seasonal allergies instead of just reacting to them

This is the episode for you!

Do natural and herbal remedies actually work for allergies, or is it mostly hype? In this episode of My Allergist Dad, Drew poses that question to his dad, Dr. Z, a top allergist and immunologist, and the answers go way beyond “drink this tea.”

They break down real, evidence-backed options like quercetin with bromelain, nettle tea, probiotics, and vitamin C, and explain how food itself can act like medicine. You’ll learn why a diet full of fruits and vegetables can reduce inflammation, how your gut microbiome connects to allergies, and why lifestyle changes matter just as much as supplements.

Along the way, they talk dust mites, air-drying clothes, freezing stuffed animals, and whether honey makes a difference or is benefitting from the placebo effect. Then the episode turns personal as Dr. Z shares his own childhood battle with asthma and the moment that set him on the path to becoming an allergist.

It’s a mix of practical allergy advice, myth-busting, and a father-son story about learning how to breathe better—literally and figuratively.

You grew up with pets. They slept on your bed. You were fine. Then you leave for college, come home for the holidays… and suddenly your own dog makes you break out in hives. What happened?

In this episode, Drew and his allergist dad, Dr. Z, unpack a listener’s question about “losing immunity” to pets—and whether that tolerance can come back. They explain how living with an animal can act like “natural allergy drops,” why time away can make symptoms feel way worse, and how stress, sleep, and college life can throw your immune system out of alignment.

You’ll learn the difference between true “immunity” and changing reactivity, why your body has an allergy threshold, and what to do if going home now feels like walking into a sneeze factory. From pre-gaming visits with meds to long-term sublingual immunotherapy, this episode offers practical ways to stay connected to your family and their pets—without suffering.

If you’ve ever wondered why your childhood dog suddenly feels like a biological weapon, this one’s for you.

Itchy, blistering skin that won’t go away? Before you blame food, pets, or seasonal allergies, it might be allergic contact dermatitis, a delayed skin reaction caused by everyday products you don’t even realize are touching you.

In this episode of My Allergist Dad, Drew sits down with his dad, Dr. Z, to break down what allergic contact dermatitis actually is, how it’s different from hives or classic allergies, and why antihistamines often don’t help. They share real patient stories involving shampoo, soap, shaving cream, lip balm, jeans buttons, hairdressers, hand sanitizer, and even “all-natural” products that turned out to be the real culprits.

You’ll learn:

• The difference between allergic reactions, irritant reactions, and contact dermatitis

• Why rashes can show up days after exposure

• What patch testing is and how it works

• Common ingredients in products like fragrancesfragrances, preservatives, metals, and dyes that cause reactions

• Why “natural” doesn’t always mean safe for your skin

If you’ve been itchy, miserable, or bouncing between doctors without answers, this episode might finally explain what your skin has been trying to tell you.
