What is food allergy?
Food allergy is a reaction of the body's immune system to some substances in food. A very low level of an allergenic substance may cause an allergic reaction in susceptible populations. A local survey revealed that about 1 out of 20 children in Hong Kong was reported to have food allergies.
Common allergens are:
- Cereals containing gluten
- Peanuts, soybeans
- Tree nuts
Symptoms of food allergy include swollen face, tongue or lips, shortness of breath and itchy skin. Anaphylactic shock, an acute, severe and potentially life-threatening allergic reaction may develop in severe cases.
Seek medical advice at once if the following symptoms develop after meal:
- Swollen face
- Swollen tongue
- Swollen lips
- Shortness of breath
- Itchy skin
- Anaphylactic shock
