A true milk allergy is a reaction to one or both proteins in milk – casein and whey. Both are present in any milk variant whether skim or whole. An actual allergy triggers respiratory, digestive and skin issues including hives and itchiness and can even lead to anaphylaxis.
Is there a difference between intolerance and allergy?
If the individual experiences bloating, abdominal pain, intestinal distress and gas after consuming whole milk without respiratory symptoms, it indicates lactose intolerance.
Milk allergy can trigger a variety of symptoms including runny nose, wheezing, hives, vomiting and digestive issues such as nausea and diarrhea. These symptoms might be severe after consuming processed foods that include concentrated milk protein such as casein or whey than after ingesting ordinary whole milk.
Why am I allergic?
If an individual has milk allergy, the immune system initiates a response to the proteins present in milk which is identified as a threat. Antibodies are released which bind to the allergens and histamine triggers the allergy symptoms.
It is important to note that whole milk includes curds, whey and all the proteins capable of triggering an allergic reaction. Most children can outgrow milk allergy including those who have a history of severe reactions.
Close look on the indications
An individual with whole milk allergy can experience a reaction in just minutes up to several hours after consumption. The usual indications include:
- Hives
- Flushed chest and face
- Itchiness
- Rashes
- Congestion
- Runny nose
- Coughing
- Sneezing
- Abdominal cramps
- Nausea
- Vomiting
- Diarrhea
In case the individual has trouble breathing and feels that his/her throat is swollen, a doctor should be consulted right away since this is an indication of anaphylaxis.
Preventive measures
If diagnosed with milk allergy, the allergy is not limited to whole milk. Buttermilk, skin milk, yogurt and ice cream can also trigger a reaction.
Processed, concentrated milk protein is present in commercial products including cakes, breads, snacks, frozen dinners and cookies. Remember that processed foods that contain casein and whey must be avoided. It is recommended to include vegetables, lean protein, fruits and whole grains that do not have dairy in the diet.
