The Australia New Zealand Food Authority (ANZFA) embarked yesterday on a poster campaign in the countries' supermarkets and doctors' waiting rooms, after four fifths of consumers confessed to not understanding all the nutritional information provided on the labels of packaged foods.

Last November, food standards ministers agreed to overhaul labelling laws on all packaged foods, making it essential that manufactures list the ingredients that can cause allergic reactions, sugar and saturated fats levels. 86% of respondents in a recent survey commented however that information explaining nutritional labels would be helpful.
