My Allergist Dad

Drew and his dad, Dr. Z, review the American Academy of Allergy, Asthma & Immunology’s tips for reducing seasonal pollen exposure, agreeing they can help but challenging the “avoidance” philosophy that keeps people inside. Dr. Z argues for “treat the cause, defeat the symptom” by improving tolerance through immunotherapy and proactive anti-inflammatory treatment so patients can enjoy spring. He explains the priming effect and early vs late-phase allergic responses, why antihistamines often lead to breakthrough congestion as the season progresses, and why starting nasal steroids (e.g., Flonase, Nasacort, Nasonex, Rhinocort) at least two weeks before a predictable season can blunt worsening symptoms. They discuss timing for preseasonal sublingual immunotherapy (preferably about two months before symptoms) and note medications don’t interfere with desensitization.00:00 Pollen Avoidance Tips00:48 Meet the Allergy Doc02:21 Avoidance vs Tolerance02:57 Treat Cause Not Symptoms05:07 Start Nasal Steroids Early06:43 Priming Effect Explained09:18 Early vs Late Response10:48 Decongestants and the D12:16 Timing Your Allergy Plan13:28 Cat Party Asthma Story17:17 Late Phase Asthma Hit18:06 Preseason Meds Strategy19:09 Sublingual Timing Guide20:35 Allergy Shot Love Story22:48 Pollen vs Dust Mite25:49 Control Not Avoidance28:44 Year Round Allergy Plan30:35 Meds vs Immunotherapy32:24 Wrap Up And Disclaimer📩 Have a question for the show?Email: [email protected]

Drew and his dad, Dr. Z, discuss why some people get severe-looking mosquito bite reactions while others don’t, explaining that mosquitoes don’t have venom and big welts are often due to a heightened histamine response rather than a true allergy. They compare this to stinging insect venom allergies, emphasizing that bee/wasp anaphylaxis can be life-threatening but is highly treatable with venom immunotherapy (allergy shots), which is about 85–90% effective and can prevent reactions even after future stings; Dr. Z notes patients should still carry epinephrine. They cover common stinging insects treated (honeybee, wasp, yellow jacket, and hornets), clarify that snake venom toxicity differs from allergy, and note rare snake-bite anaphylaxis and possible allergic reactions to antivenom, including considerations with alpha-gal. They also mention mosquito attraction factors like blood type, CO2, sweat, and heat.00:00 Creepy Crawlies Intro00:41 Rhode Island Snake Talk02:14 Mosquito Bite Reactions04:14 Bee Allergy Treatment06:37 How Venom Shots Work08:50 Snake Venom vs Antivenom15:15 Fire Ants and Bee Reactions23:05 Why Mosquitoes Pick You25:05 Wrap Up and PSA

Drew and Dr. Z discuss the nine major foods responsible for most allergic reactions in the U.S.—milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame—and use them to explain how food allergy (IgE-mediated) differs from food sensitivity and broader inflammation tied to gut and skin microbiomes. Dr. Z describes eosinophilic esophagitis as a likely food-sensitivity condition that can present with choking, reflux, and fibrosis, often linked to common trigger foods, and notes possible connections to IgG4 and desensitization therapies. They explore dysbiosis, how antibiotics, processed foods, sugar, emulsifiers, and pesticides like glyphosate may disrupt microbiome balance, and why lifestyle factors such as stress, sleep, exercise, and diet can influence allergy symptoms and reactivity thresholds. They emphasize bioindividuality, the limits of current microbiome testing, and the need to address root causes rather than only treating symptoms.00:00 Big 9 Food Allergens01:05 Meet My Allergist Dad02:41 Food Sensitivity vs Allergy03:13 Eosinophilic Esophagitis Basics06:45 Microbiome Balance and Eczema09:56 Testing and Dysbiosis Limits11:52 Lifestyle Stress and Gut Brain13:06 Pesticides, Processed Foods, and Inflammation16:03 Integrative Nutrition Goals19:26 Root Causes of Rising Allergies22:38 Birth Genetics and Exposure25:18 Healing Thresholds and Gluten Free Trap31:28 Wrap Up and Disclaimer📩 Have a question for the show?Email: [email protected]

Drew and Dr. Z welcome Dr. Mark Charbonneau, a microbiologist and biotech leader at Solaria Bio, to discuss why it’s challenging to beneficially modify the gut microbiome despite major advances in understanding its role in health, immunity, and disease. They explain the microbiome as an ecosystem that influences immune balance between inflammation and tolerance, including regulatory T cells, and how disruptions like antibiotics can contribute to dysbiosis and conditions such as atopic dermatitis. Mark describes Solaria Bio's medical food symbiotic product, Bondia, designed from four fruit-and-vegetable–derived probiotics to reduce gut-driven inflammation, improve gut barrier function, slow aging and menopause-associated bone loss, while also improving GI symptoms in clinical studies. They emphasize proactive, root-cause approaches alongside lifestyle measures like resistance training, calcium, and vitamin D.Solaria website: www.solaria.bioBondia product page: https://solaria.bio/products/bondiaMark's professional socials:YouTube: https://www.youtube.com/@drmarkcharbonneauInstagram: https://www.instagram.com/drmarkcharbonneau/📩 Have a question for the show?Email: [email protected]

Drew and his dad, allergist Dr. Z, explain angioedema as deep tissue swelling that can occur with hives or as part of anaphylaxis, sometimes affecting lips, eyes, tongue, or the airway. They distinguish common, usually non–life-threatening angioedema from the rare but dangerous hereditary/acquired form involving the complement pathway and C1 esterase inhibitor deficiency, which can be triggered by trauma or surgery and screened with a C4 blood test. Dr. Z also discusses non-IgE mechanisms such as bradykinin/kinin pathways, as well as medication contributors that can worsen swelling.📩 Have a question for the show?Email: [email protected]

In this episode, we go beyond the medical advice and get real about the day-to-day reality—from scary first reactions and EpiPen moments to the constant planning around food, school, and social life.

Dr. Z is joined by his wife (who’s been through it all) and their daughter, a new mom navigating allergies for the first time. Together, they share honest stories, practical tips, and the emotional side of being the one responsible for keeping your child safe.

We get into:

• The fear every parent feels after a first allergic reaction

• How to prepare without putting your kid “in a bubble”

• Why anxiety can sometimes be worse than the allergy itself

• Real-life strategies for managing food allergies, eczema, and asthma

• What’s changed for parents today (and what hasn’t)

Plus—some surprisingly funny moments about airport food mishaps, allergy “perks,” and why preparation is everything.

If you’re a parent, thinking about becoming one, or just trying to better understand allergies—this episode is for you.

Have you heard that your body completely resets every 7 years? Does that mean your allergies can change too?

This week on My Allergist Dad, Drew and Dr. Z break down one of the most common allergy myths and explain what actually happens inside your immune system as you age.

They dive into:

• Whether allergies really change every 7 years
• If it's possible to naturally outgrow allergies
• Why some people suddenly develop allergies later in life
• How genetics and environment influence allergies
• Why allergies often run in families
• What epigenetics means for your immune system

Plus, Dr. Z shares real examples from decades of allergy practice—including why siblings can have completely different allergies and how lifestyle and environment can trigger them.

If you've ever wondered why your allergies changed—or why your kids might have them—this episode explains it all.

In this episode of My Allergist Dad, Dr. Z and Drew break down the real connection between stress, the immune system, and allergic reactions. From cortisol and immune tolerance to insulin spikes, mast cells, and metabolic syndrome, we explore why stressful seasons of life often lead to more sneezing, hives, asthma, and inflammation. 

You’ll learn:

• How stress lowers your immune “tolerance” threshold

• Why chronic stress can increase allergic reactivity

• The link between insulin resistance, overeating, and mast cell activation

• How metabolic health affects asthma and allergies

• Why modern life may be making allergies worse

• Practical lifestyle shifts that can calm inflammation naturally

We also talk about shingles, immune weakness, preventive care, and why treating symptoms alone isn’t always enough.

If your allergies seem worse during intense work weeks, emotional stress, poor sleep, or unhealthy eating patterns — this episode connects the dots.

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."
