Consumers have won the right to know more about what they eat, but manufacturers claim it will cost $400 million and result in a 2 per cent rise in food prices, The Australian reported at the weekend. New labelling laws will mean that sugar and so-called "bad" or saturated fats will have to be listed on packaged food. Under the new rules, manufacturers will also have to list the main ingredients as a percentage in foods. The changes were approved by a meeting of the 10 Australian and New Zealand food ministers in Sydney last week, despite attempts by the commonwealth to delay introduction of the changes, and a concerted campaign by food manufacturers. The new rules mean nutrition labels, already printed voluntarily on 70 per cent of foods, will be mandatory and that information on saturated fats and sugars will have to be added. The changes are expected to be introduced from 2003.
