COMMON ALLERGENS → Dairy
DID YOU KNOW?
80% of children with a milk allergy outgrow it before they turn 16 years old!
- The term dairy encompasses animal milk and milk products such as cheese, ice cream, butter, yogurt, etc. In the United States, dairy allergy most commonly references cow’s milk.
- Cow’s milk allergy is the most common allergy in early childhood, and typically develops two months after first exposure- usually between the ages of 1 and 2.
- GI symptoms (diarrhea, bloating, cramps, vomiting) are most common after ingestion, followed by skin symptoms (hives, swelling, itching) and anaphylaxis.
- Milk allergy cross-reactivity is common, those allergic to cow’s milk will also likely be allergic to goat, buffalo, and/or camel milk, etc.
- It’s important to distinguish a dairy allergy, which involves the immune system, from a sensitivity like lactose intolerance, which is attributable to an enzyme deficiency (i.e. lactase).
