Letter to the Editor

Editor, – Food Standards Australia New Zealand (FSANZ) has recently approved a new sugar substitute called isomaltulose, but this product may pose a risk to individuals with disorders of fructose metabolism.

FSANZ has assessed isomaltulose and concluded that it is safe for the general population. It is not suitable for those very few people with disorders in fructose metabolism or people with sucrase-isomaltase deficiency. People with these conditions are recommended to avoid foods containing isomaltulose.

We want the medical and dietetic professions to be aware of this and so are informing the peak professional bodies and the medical media about this product. In addition, FSANZ has prepared a fact sheet on isomaltulose which is available on its website (
