Whey, soy and caffeine allergies are different because different proteins cause a reaction in the body, but are similar in that they are all food-related allergies. Whey and soy allergies are more commonly found in young children and are outgrown by the age of 3, according to MayoClinic.com, while caffeine allergies can affect anyone at any age. If you experience any unpleasant side affects after eating or drinking products containing whey, soy or caffeine, talk with an allergist for an accurate diagnosis.
Whey Allergy
Whey protein makes up about 20 percent of cow's milk and may be found in packaged foods such as desserts, hot dogs and pastas. A whey allergy is hypersensitivity of the immune system that causes the body to produce antibodies and histamine, according to Kids Health. Common symptoms of a whey allergy are skin rashes, such as hives or eczema, asthma and digestive issues. Someone with a whey allergy may experience vomiting, develop cramping or abdominal pain within minutes after ingesting whey. A whey allergy is different from lactose intolerance, which may have similar symptoms.
Soy Allergy
Products of soy beans are considered one of the most common food allergens in childhood, according to MayoClinic.com. Soy is required by the FDA to be disclosed on all pre-packed foods as a possible allergen. Soy may be found in cheese, certain bread products and cereals. Read the labels of the package before eating any food. A soy allergy commonly produces symptoms of tingling in the mouth, hives and dizziness.
Caffeine Allergy
A caffeine allergy is considered a food-related allergen but differs in symptoms. Most of the symptoms of a caffeine allergy are related to behavior and digestive issues, according to Doctor Yourself. An allergic reaction to caffeine can cause a person to act manic, depressed or hyperactive. Some people experience extreme headaches after consuming caffeine. Caffeine is commonly found in coffee, tea, soda and chocolate.
Treatment
MedlinePlus states that the only treatment for food-related allergies, such as whey, soy and caffeine allergies, is to abstain from eating foods that contain the substances. There is no cure for food allergies, but they are manageable. Minor allergic reactions, such as skin rashes and nasal congestion, may be treated with oral antihistamines. Digestive symptoms will not subside until the proteins pass through the body. Common digestive medications will have no effectiveness on symptoms from a food allergy.
Warning
As with any food allergy, there is a risk of anaphylactic shock. If you develop symptoms, such as lightheadedness, shortness of breath or a drop in blood pressure, call 911.
