Can food allergies cause itchy skin?

Your nose starts running every time you dare order spicy food. It seems like your body is reacting even though the waiter hasn’t even brought the food yet. Or you get a headache after just one glass of wine that is so pounding and terrible that you can’t imagine having another. Beans give you gas, and you start having diarrhea when you drink milk or eat cheese.

Many people have reactions to foods like these now and then, but they’re usually food intolerances or sensitivities. Your immune system doesn’t cause them.

A food allergy is not quite the same thing. Your body identifies certain foods as harmful which actually aren’t. Your immune system can respond in various ways, and one of them is itchy skin.
Food allergies can be deadly, but there is something very simple you can do to manage them – avoid foods you are allergic to!

What foods can cause itchy skin?

The most common foods that can cause itchy skin are milk (mostly in children), soy, eggs, tree nuts, peanuts, wheat and other grains with gluten, including rye and barley, and fish and shellfish. Less common ones include corn, pork, beef, gelatin, and certain seeds and spices.
Itchy skin rashes like hives or eczema are very common. Other concurrent symptoms may include a runny or stuffy nose, itchy eyes, an itchy mouth or ear. In more extreme cases, you may have trouble breathing or swallowing, chest pain, arrhythmia and light-headedness.

Because small children may not be able to describe what they are feeling, they might say something like, “My tongue feels heavy,”, “My mouth is tingling,” or “I’ve got a frog in my throat.” A dry and raspy or squeaky voice or poor articulation can also signal an allergic reaction in kids.
