Does Whey Protein Cause Inflammation?

Whey protein is one of the most common food allergies that cause inflammation in various places throughout the body, according to Kids Health 1.

Talk with your doctor if you suspect that you may have an allergy to whey protein.

What is Whey Protein?

Whey protein is found in cow’s milk and is commonly used a dietary supplement to increase protein consumption. Milk contains whey and casein proteins, which can trigger allergic reactions in some people. If you’ve been diagnosed with a casein protein allergy, you should still avoid consuming whey protein, because it may contain traces of casein protein molecules. Whey protein may be used in protein beverages, protein powders and protein bars. Therefore, read the ingredients and allergy warning on the product’s package before consumption.

Inflammation is the result of increased blood flow to certain areas of the body. During an allergic reaction to whey protein, the body releases immunoglobulin E antibodies to attack the protein, according to the American Academy of Allergy, Asthma and Immunology. Although, the protein is safe for consumption, the immune system malfunctions, attacking the protein as if it were an intruder. The antibodies communicate with white blood cells throughout the body, which, in turn, produce histamine -- a natural chemical in the body that protects against infections. Too much histamine released in soft tissues, however, can cause your blood vessels to dilate, resulting in increased blood flow, inflammation and irritation.

Respiratory and Digestive Systems

Inflammation that occurs in the respiratory system results in various common allergy symptoms. Sinus inflammation causes a stuffy nose, runny nose, sinus headaches, facial tenderness and facial pressure. If your airways become inflamed, you may develop asthma-like symptoms, including shortness of breath, chest pain, wheezing and coughing. Your digestive system can also develop inflammation, causing nausea, diarrhea, vomiting, cramping, abdominal pain and excessive gas.
