Soy, an Asian legume, is often present in foods and can cause allergic reactions when consumed. Be sure to read food labels carefully to avoid products containing soy.Signs of a soy allergy may include itchy skin, hives, wheezing, and runny nose. In severe cases, anaphylaxis may develop.

Eggs are a common allergen and can cause skin allergies in people with egg allergies. Allergic reactions are caused by proteins found in both egg whites and egg yolks. Symptoms may include rash, itching, swelling and/or hives. This reaction is usually severe and requires immediate emergency treatment.

Wheat

Wheat, a nutrient-dense grain, can cause skin allergies when your immune system reacts to one or more of its proteins. This can manifest as a rash, itchy mouth and throat, or other symptoms.If you have a wheat allergy, make sure you bring an epinephrine auto-injector when you go out to eat and inform any restaurant staff of your food sensitivity. This will help prevent cross-contamination between dishes.

Cow's milk

Cow's milk allergy (CMA) is an immune system reaction to the protein in cow's milk. This can manifest as a rash, swelling, and difficulty breathing for sufferers.Children with cow's milk allergies must avoid all foods that contain cow's milk or other dairy products unless otherwise directed by their doctor. In addition, medicated toothpastes and chewing gum containing Recaldent(r), which is made from cow's milk protein, should also be avoided.Frequent spitting up and frequent reflux that could indicate a milk allergy should be investigated. Diarrhea and blood in the stool can also be signs of an allergic reaction.

Shellfish

Shellfish are aquatic invertebrates that are divided into two groups: crustaceans (shrimp, lobsters and crabs) and mollusks (clams, oysters and mussels).If you are allergic to shellfish, your immune system reacts to proteins found in the mollusk or crustacean. This can cause itchy hives or other symptoms.SpicesSpices are essential elements in many dishes and add flavor and depth. Unfortunately, they can also cause skin reactions in sensitive individuals.Spice allergies can be caused by handling spices or eating foods that contain them. In rare cases, they can lead to anaphylaxis, a severe allergic reaction that may require medication for treatment.Similar to a food allergy, an allergic reaction to spices can manifest as itching and redness on the skin (urticaria). Itching can also spread to the mouth and eyes.
