Food products bearing the Heart Foundation's Tick will once again have to meet sugar content guidelines.
The foundation has reintroduced sugar as a criteria after a new World Health Organisation recommendation to reduce daily intake of sugar to less than 10 per cent of total energy.
Tick programme manager Deb Sue said a sugar criteria had been replaced in 2001 with energy, which includes sugar and fat.
At the time evidence showed a stronger link between energy and cardiovascular disease, she said.
"Previously, the evidence between sugar intake and heart disease was not as strong as it is now and we are moving with the latest research."
