Alerji Nedir? Alerjiler Neden Yok Olmadı?

Summer is here, the flowers are blooming... Allergies are rampant again, aren't they? Currently, 1 in 4 people in Türkiye has allergies. And some allergies aren't just to things we're used to, like pollen or something. Some people can have deathly allergic reactions to even drinking a clean glass of water or being exposed to the sun for a few minutes! But why? Why is there such a thing as "allergy"? Are our bodies so stupid that they can't distinguish ridiculous things like pollen and dust, and especially foods like peanuts, eggs, or milk, from real bacteria or viruses? Think about it this way: There are currently over 170 food types and over 400 proteins known to be "allergens"! And that's just "food allergies." On top of that, there's mite allergies, latex allergies, drug allergies, insect bite allergies, and so much more! But... Why do these things exist? And why are some people born with allergies, while others acquire them later in life? Is there a way to stop these allergies? Could twins be the secret? And more importantly... Why are allergies on the rise lately?
