Concerns have been raised over the presence of microplastics in gum.
A health researcher has warned he wouldn't want his own children chewing on gum, due to the health risks associated with consuming the microplastics.
University of Technology Sydney Associate Professor Brian Oliver says the health risks are 'unknown', but there's a lot of harmful conditions that could happen.
"Inflammation's sort of the precursor to a lot of chronic conditions, so diabetes, respiratory conditions - so we know that the impetuous is there. What we don't know is actually how much inflammation, and exactly how bad."
