Soy allergy is fairly common food sensitivity. Some sufferers of soy allergy have fairly mild symptoms, while a rare few can have severe physical reactions. Most common soy allergy reactions are:
• Sinus congestion
• Swelling
• Canker sores or fever blisters
• Stomach ache, gastrointestinal problems, or diarrhea
• Itching
• Hay fever type symptoms
Severe reactions can include:
• Skin conditions such as acne or eczema
• An asthmatic reaction
• Anaphylaxis
Most commonly soy allergy is treated by avoiding foods that contain soy. This can be more difficult than a non-sufferer might suspect since soy has become an important food staple worldwide. Soy protein is added to some broth that's used in canned chicken and tuna. Soy flour can be found in hamburger buns and in hydrolyzed vegetable protein so even buying something as common as a burger and fries means making inquiries about ingredients first. The same thing goes for other food containing flour that might be soy based such as doughnuts, pancakes, breads, or biscuits.
Naturally soy protein can be found in soybeans, soy nuts, soy sprouts and anything made from these sources. Anyone with a soy allergy should avoid edamame, mso, natto, soy milk, soy sauce, tamari, tempeh, tofu, soybean butter, shoyu sauce and anything else containing the soy protein that triggers a reaction.
If soy is accidentally ingested most common aids such as antihistamines are usually effective in treating the resulting symptoms. If a more severe action like anaphylaxis should be the result, then medical attention is needed immediately. Anaphylaxis can result in the soy allergy sufferer have a sudden increase in heart rate, sudden weakness, difficulty breathing, sudden drop in blood pressure and unconsciousness. If the sufferer isn't given proper treatment as soon as possible this can result in death.
Soy allergy that begins in infancy or childhood might be eventually be outgrown by the sufferer. For most adults mild to moderate symptoms are the only problems experienced. Most soy allergy sufferers can tolerate up to 400 mg of the protein before having a response, but the best bet is to avoid entirely if possible.
