Food intolerances

A food intolerance is an unpleasant reaction to food that, unlike a food allergy, does not involve the immune system but may occur due to incomplete digestion and/or absorption of a specific food.1 Symptoms of food intolerance can vary both in their nature and also severity. For more information on food intolerances, please use our quick reference guide to understand the difference between food allergy and intolerance.

Common food intolerances

Food intolerances are thought to be more common than food allergies with common food intolerances including lactose, wheat, gluten and yeast.2 To prepare for the consultation with your healthcare professional, consider making an accurate record of your toddler’s diet.

Managing food intolerances

Your toddler’s food intolerance can normally be managed by avoiding or reducing the amount they eat of the food that is causing their symptoms.1 Before you consider eliminating any foods from your toddler’s diet, it is important to speak to your healthcare professional. They will be able to advise you on how to interpret food labels and on suitable alternatives to the foods that need to be removed from your toddler’s diet.
