Nevhodná strava a alergie: co jíst a co vynechat

When you have allergies, what you eat isn’t just about nutrition—it can make your symptoms worse or better. nevhodná strava, potraviny, které aktivují nebo zhoršují alergické reakce, i když nejsou přímým alergenem. Also known as potraviny s křížovou reakcí, it often connects pollen allergies to foods like apples, carrots, or nuts—something many people don’t realize is linked to their sneezing fits. If you’re allergic to birch pollen, eating raw apples might make your mouth itch. That’s not a coincidence—it’s a zkřížená alergie, reakce imunitního systému na podobné bílkoviny v pylu a potravinách. You’re not allergic to the apple. Your body confuses it with birch pollen. And that’s just one example.

Many think avoiding gluten or dairy will fix their allergies. But unless you have celiac disease or a true food allergy, cutting out these foods won’t help—and might even make you nutritionally weaker. The real issue is often potravinová alergie, skutečná imunitní reakce na konkrétní bílkovinu v jídlu, která může způsobit závažné příznaky. That’s different from intolerance or cross-reactivity. If you get hives after eating peanuts, that’s a food allergy. If your throat gets itchy after eating raw carrots during pollen season, that’s cross-reactivity. One needs emergency care. The other just needs cooking or timing your meals right.

Co skutečně zhoršuje alergie skrze jídlo?

Processed foods full of sugar, preservatives, and artificial additives can increase inflammation in your body. That doesn’t mean they cause allergies—but they make your immune system more reactive. If you’re already fighting pollen, a sugary snack might push you over the edge into worse symptoms. On the flip side, foods rich in omega-3s, probiotics, and antioxidants (like fatty fish, yogurt, berries) can help calm your immune response. You don’t need fancy supplements. Just eat real food.

And don’t forget the timing. If you’re allergic to tree pollen in spring, avoid raw fruits and vegetables that cross-react with it—especially in the morning when pollen counts are highest. Cook them instead. Heat breaks down the proteins that trick your immune system. A baked apple won’t trigger the same reaction as a raw one. Simple change. Big difference.

Some people swear by herbal remedies like nettle or honey. There’s some science behind them, but they’re not magic. Nettle might help with runny nose. Local honey? Probably not. But if you feel better using them, and they don’t hurt you, why not? Just don’t replace proven treatments like nasal rinses or immunotherapy. You can use herbs as a side support—not as your main defense.
