Curious Minds is where big questions meet everyday curiosity, exploring how science, technology, and imagination shape our world. From kids to grandparents, everyone can find something to spark their mind here.

If you think allergies are just something you grow out of, think again. Today we explore sudden-onset adult allergies, where biological defense systems collide with modern lifestyle pressures.

In this episode (Ep. 14): Join Mei Lin as we dive into the science of why the body suddenly turns against favorite foods from a sudden shellfish reaction in São Paulo, to a case of "mistaken identity" involving apples in Seoul, to the hormonal shifts triggering dairy issues in London.

We break down how the immune system is reshaping our definition of "enemy", what experts worry about most regarding the "Big 9" allergens, and the surprising ways innovators are looking to gut health and microbiome therapies for solutions.

You’ll hear about:

• Biological Armored Vehicles: Why the stable proteins in the "Big 9" foods (like shellfish and peanuts) are so good at surviving digestion and triggering alarms.

• The Gut-Immune Connection: How antibiotics and microbiome disruption can "recalibrate" your immune system to flag friends as foes.

• Molecular Mimicry: The fascinating science of Oral Allergy Syndrome, where your body confuses an apple for birch pollen.

• Bonus: The invisible link between climate change, longer pollen seasons, and the food on your dinner plate.

And here’s the takeaway: Allergies aren't just bad luck, they're your body's way of crying out for a world that's changing faster than we can adapt.

Stay curious, stay engaged because listening to your body's whispers now might just prevent the screams later.
