Even though grapes are not included as common allergens, children might develop an allergy. Nevertheless, the child might not have grape allergy but a reaction to other substances present on the fruit. If you suspect that the child had a reaction to grapes, a doctor should be consulted for allergy testing to pinpoint the precise cause. Remember that cross-reactions to other foods might also occur.
The proteins in food are responsible for causing allergic reactions. Take note that grapes contain enough proteins to trigger a reaction.
The proteins believed to trigger an allergy in grapes include 3 specific proteins. The main protein allergen in grapes is LTP (grapes lipid transfer protein). The immune system overly reacts and releases antibodies and chemicals. These chemicals are responsible for the allergy symptoms.
What are the signs?
Grape allergy can trigger symptoms that are strikingly the same as to other allergens. The usual symptoms include:
- Stuffed or runny nose
The oral allergy symptoms that might arise include swollen lips, mouth and throat as well as itchiness in the throat and irritation of the eyes or gums. Anaphylaxis which is a severe reaction might include hives, low blood pressure, facial swelling, difficulty breathing, swollen throat and wheezing.
Important considerations to bear in mind
It is likely to have an allergic reaction to one form of grape and not to others. It is also possible that an allergy to one variant of grape indicates sensitivity to all grapes, raisins and wine-related products.
In case the child ends up with a reaction to one variety of grape, it is not advisable to provide the child with any other grape products until he/she has been tested for allergies.
