This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how 'attractive', 'believable', and 'new and different' they found each concept and their 'intention to try' . Each variable was significantly related to intention to try (p<0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed. independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim.

Foods such as breads and breakfast cereals enriched with a combination of soy protein (soy grits and/or soy flour) and whole linseed are gaining popularity. Regular consumption of either whole grains or soy protein can lower risk factors for coronary heart disease. Furthermore, linseed is a rich source of the omega-3 fatty acid. alpha-linolenic acid (LNA), with purported cardiovascular benefits. The aim of this study was to determine the effect of daily consumption of soy and linseed containing foods and Canola (as an added source of LNA) on plasma lipid concentrations in 20 mildly hypercholesterolaemic postmenopausal women. Fasted blood samples were taken initially and after 3 and 8 weeks to assay plasma lipids and both plasma and erythrocyte membrane fatty acids. Urinary isoflavones were also measured. Data from 18 subjects were used for analysis. Plasma total, low-density lipoprotein (LDL) and non-high-density lipoprotein (HDL) cholesterol concentrations fell significantly (10, 12.5 and 12%, respectively) within 3 weeks. Although attenuated, there were still significant reductions in total and non-HDL cholesterol (5 and 6.5%, respectively) after 8 weeks of intervention. These reductions were associated with increases in urinary isoflavone excretion. This pilot study indicates that regular inclusion of foods containing soy and linseed in the diet may improve plasma lipids in subjects with hypercholesterolaemia.
Aim: Australia and New Zealand are currently preparing a new food standard code, which will allow the use of health claims on food products and in associated advertising. The aim of this study was to obtain preliminary information about the current use of health claims on the Internet and the level of compliance of these claims with existing regulations. Methods: From August to October 2005 a survey was conducted of 1068 websites associated with the top 20 food processing companies in Australia, and an additional 683 websites for food products found to carry health claims in previous studies of product labels and magazine advertisements. The results were compared with those from a 2003 survey of health claims on the labels of 7850 products. Results: The survey found that 14.5% of food product websites carried a health claim, and 40.7% and 37.0% of products previously identified as carrying claims on product labels or in magazines respectively, had Internet claims. 21.4% of claims were located directly on the food product web page, but the majority (78.6%) were on associated links within the manufacturer's website. Many of the claims (19.7%) were high level or therapeutic claims not permitted by current food standards. Conclusions: Health claims are not being made more frequently on websites compared to product labels, but there is a greater prevalence of high level and therapeutic claims made on the Internet. In future food standards enforcement will need to give greater priority to monitoring the use of health claims on the Internet.
