Food Allergies


Food allergies are on the rise rapidly worldwide. It affects 1 in 20 children and about 2 in 100 adults (ASCIA 2016). An allergy occurs when the immune system overreacts to a seemingly harmless substance (food protein in this case). The symptoms usually involve vomiting, wheezing, swelling, itching, hives, eczema, or in severe cases, anaphylaxis. Food allergy can also present itself in a less obvious way in infants suffering from colic, reflux, eczema, ongoing diarrhoea and poor growth. 

The most common food allergens are cow’s milk, egg, peanut, tree nuts, fish, shellfish, sesame, soy and wheat. Food allergies are commonly diagnosed in children under the age of 5 and most children outgrow the food allergy over time. However, allergies to peanut, tree nut, fish and shellfish tend to persist into adulthood. If the food allergy develops for the first time in adults, it usually persists. 

It is important that an allergy is properly diagnosed by your doctor or allergist/immunologist. A diagnosis is made based on clinical history, symptoms and scientifically proven allergy tests (skin prick test, blood IgE testing or supervised food challenges). Alternative practitioners offer unorthodox testing that are unproven and expensive (e.g. IgG test, hair analysis, kinesiology). These tests are unreliable and leads to unnecessary food restrictions. For more information about allergy testing, refer to this document

Managing Food Allergies

When your child is first diagnosed with a food allergy, you are often given a long list of foods that needs to be avoided. It may be fairly straightforward if it is a single allergen such as peanuts. However, it gets very challenging when there are multiple food allergies involved. Children with multiple food allergies may experience food aversion, growth issues and malnutrition long-term if their diets are overly restricted. Parents often struggle to understand food labels, prepare appropriate meals for the whole family and special events such as birthday parties. They are constantly worrying about their child having accidental exposures to the allergen(s) at school or while on holidays.
