Important reminder

The Allergy Community is not a medical service, and this guide is for general information only. Ingredient swaps can affect flavour, texture, and structure, and they may not be suitable for every allergy or dietary requirement.

Always:

• read product labels carefully
• check for allergen warnings and ingredient changes
• choose substitutes that are suitable for your own individual needs
• seek professional advice where needed

If you live with a severe allergy, multiple allergies, or are unsure whether a substitute is safe for you or your family, always check with an appropriate healthcare professional or allergy specialist before relying on new ingredients or food products.
