What percentage of kids allergic to cow's milk are also allergic to soy milk?

1. 10%

2. 25%

3. 50%

4. 75%

The correct answer is: 25%

The correct answer is that approximately 25% of children who are allergic to cow's milk also show an allergy to soy milk. This crossover occurs because both cow's milk and soy contain proteins that can trigger allergic reactions in susceptible individuals. Understanding the context is essential when considering allergies in children. Cow's milk protein allergy is one of the most common food allergies in early childhood, and while soy is often used as a substitute for cow's milk, those with a cow's milk allergy may react to soy due to protein similarities. The percentages that indicate a greater likelihood (like 50% or 75%) are excessive, as research shows that only a relatively small subset of children with cow's milk allergies will also react to soy. This emphasizes the importance of individualized assessments when managing dietary restrictions and potential allergens for children.
