Is your child experiencing unexplained symptoms after meals? Unlike food allergies that cause immediate reactions, food intolerances can be subtle and difficult to identify, affecting up to 25% of Australians. Any age group can be affected, but it is a common concern for parents of young children.

Common symptoms to watch for:

• Gut-related issues: diarrhoea, stomach pains, bloating, constipation

• Respiratory problems: sinus congestion, recurring coughs

• Nervous system effects: headaches, behavioural changes, fatigue

• Skin reactions: rashes, eczema flare-ups

Most common intolerances in children include:

• Milk products (particularly in children under 2 years)

• Lactose (the sugar in milk)

• Wheat and gluten

• Food preservatives and additives (colourings, sulphites, benzoates)

How are food intolerances diagnosed?

Unlike allergies, there's no single test for food intolerances. Diagnosis typically involves symptom assessment, food diaries, and sometimes elimination diets under medical supervision.

Many children can tolerate small amounts of trigger foods, and some may outgrow their intolerances. However, others may experience symptoms long-term, requiring ongoing dietary management.

Important note: Food intolerance is different from food allergy, which involves immune system reactions and can cause immediate, potentially life-threatening symptoms.

If you suspect your child has a food intolerance, speak with your GP before eliminating food groups. This ensures proper diagnosis, adequate nutrition, and appropriate management for your child's specific needs.
