Milk contains both whey and casein proteins, according to Kids Health. Whey proteins are found in the liquid portion of dairy products, while casein proteins are in the curd, or hard portion of milk used to make cheese. If you've been diagnosed with a whey and casein allergy, you need to avoid all products that contain milk or dairy by-products. The most effective treatment for a milk allergy is complete elimination of milk from the diet, according to MayoClinic.com. Whey and casein allergies are incurable but can be managed with diet.
Cause
Whey and casein allergies are caused by a malfunction of the immune system. When you ingest either of the proteins, your immune system mistakes them as a dangerous substance. The body reacts to the proteins the same way it would to a harmful virus or bacteria and creates a defense system. Antibodies and histamine are created to fight off the milk proteins, which causes common milk allergy symptoms. These symptoms include skin irritation, nasal congestion, asthma, diarrhea, vomiting, nausea and abdominal pain, according to Kids Health.
Diet Modification
Elimination of all dairy products is the most effective way to prevent a whey or casein allergy reaction. The Lucile Packard Children's Hospital states that casein proteins may be found in butter, artificial butter flavor, cream, custard, ghee, hydrolystates, lactose, nougat, sour cream, yogurt, caramel flavoring, brown sugar flavoring, high protein flour, natural flavoring and margarine. The federal government requires that all food products that contain whey or casein proteins disclose the use of milk on the label. Before eating any pre-packaged food, read all the ingredients and allergen warnings.
Calcium Supplements
The avoidance of dairy products may require you to take a calcium and vitamin D supplement to ensure you're receiving the appropriate daily amounts. Some milk substitutes, such as almond milk, soy cheeses and rice beverages may be fortified with these nutrients to still provide the needed daily intake. When dining out, Kids Health recommends asking the server if any of the dishes contain milk by-products, whey or casein.
Treatment
Depending on the severity of the allergic reaction, different treatments may be used. For minor allergic reactions, such as nasal congestion, sneezing and itchy skin, you can take an antihistamine drug, according to MayoClinic.com. Severe allergic reactions that lead to anaphylactic symptoms may require emergency medical attention and an injection of epinephrine.
