"Dermatologists are advising parents of infants and young children affected by this common skin condition to be aware of the potential for future food allergies.
Typically, a food allergy occurs rapidly (within 30 minutes from the time a person is exposed to the food), with skin symptoms such as hives and itching of the lips. More severe reactions may include respiratory, gastro-intestinal or anaphylaxis problems that could be potentially very dangerous."
There are new guidelines for diagnosing food allergies and new research re: prevention of food allergies. If you are a parent with concerns about your child developing food allergies, this article may help shed some light on the topic.
