Which tube feeding ingredient might cause an allergic reaction in a child with a milk allergy?

Casein is a protein found in milk and is a significant component of dairy products. In children who have a milk allergy, exposure to casein can trigger an allergic reaction, as their immune systems mistakenly identify this protein as a harmful substance. Symptoms of such reactions can range from mild to severe, causing discomfort and potentially life-threatening conditions.

In contrast, soy protein is derived from soybeans and is generally safe for children with milk allergies, as it does not contain dairy. Whey, while also a milk-derived protein, is separate from casein and may not be the primary concern for those with casein allergies specifically. Rice protein, being plant-based, is unlikely to cause an allergic reaction in individuals with a milk allergy. Thus, recognizing casein as a direct component of milk is crucial in understanding why it is a potential allergen for children with milk allergies.
