Two important exceptions to the relationship between energy density and fat content: food with reduced-fat claims and high-fat vegetable-based dishes

Objective: To test the hypothesis that many foods with reduced-fat (RF) claims are relatively energy-dense and that high-fat (HF) vegetable-based dishes are relatively energy-dilute.

Design: Nutrient data were collected from available foods in Melbourne supermarkets that had an RF claim and a full-fat (FF) equivalent. Nutrient analyses were also conducted on recipes for HF vegetable-based dishes that had more than 30% energy from fat but less than 10% from saturated fat. The dietary intake data (beverages removed) from the 1995 National Nutrition Survey were used for the reference relationships between energy density (ED) and percentage energy as fat and carbohydrate and percentage of water by weight.

Statistics: Linear regression modelled relationships of macronutrients and ED. Paired t-tests compared observed and predicted reductions in the ED of RF foods compared with FF equivalents.

Results: Both FF and RF foods were more energy-dense than the Australian diet and the HF vegetable-based dishes were less energy-dense. The Australian diet showed significant relationships with ED, which were positive for percentage energy as fat and negative for percentage energy as carbohydrate. There were no such relationships for the products with RF claims or for the HF vegetable-based dishes.

Conclusion: While, overall, a reduced-fat diet is relatively energy-dilute and is likely to protect against weight gain, there appear to be two important exceptions. A high intake of products with RF claims could lead to a relatively energy-dense diet and thus promote weight gain. Alternatively, a high intake of vegetable-based foods, even with substantial added fat, could reduce ED and protect against weight gain.

The challenge for the dairy industry arising from the new health claims standard: an impetus for innovation

The publication of a Preliminary Final Assessment Report on 4 April 2007 heralded another step towards the introduction of a new Health Claims Standard to be inserted into the Australia New Zealand Food Standards Code. This Health Claims Standard, once approved by the Board of Food Standards Australia New Zealand and by the Australia New Zealand Food Regulation Ministerial Council, will permit the making of certain substantiated health claims. Prior to the introduction of the new Standard, health claims have not been permitted on food labels, with the exception of claims in relation to maternal folate consumption and its positive effect in reducing the risk of foetal neural tube defects. The new Health Claims Standard as outlined in the Preliminary Final Assessment Report is likely to have a significant impact on the dairy industry. This paper seeks to analyse that impact, including threats, opportunities and challenges that the Standard poses to the dairy industry and other food suppliers.

The moral status of wrongful life claims

A wrongful life action is a claim brought by a disabled child who asserts that but for a physician's negligence he or she would not have been born, thereby being spared the suffering of life. The action is inherently controversial because the alternative to an impaired life is non-existence. Lord Griffiths has described such claims as 'utterly offensive; there should be rejoicing that the hospital's mistake bestowed the gift of life upon the child'.' This paper cuts through the rhetoric that the debate has generated and analyses whether there is a sound doctrinal basis for recognizing wrongful life actions.

Nutrition, health and related claims

The article deals with food regulations controlling the use of nutrition, health and related claims in Australia and New Zealand. It relates how such regulation of claims are managed in several ways. Examples are the Code of Practice on Nutrient Claims, vitamin and mineral claims, claims about electrolyte drinks and sports food and the Australia New Zealand Food Standards Code.

Analysing health claims policy in Australia : a case study of evidence in food and nutrition policy-making

Purpose: Health claims generally describe an association between a food product and a health outcome. There is debate whether health claims promote or obstruct healthy food selection behaviour. This study investigates the role of evidence in food and nutrition policy-making. The research question is how and why was health claims policy made in Australia? The research is innovative in its critical analysis design and its focus on building theory to help improve food and nutrition policy-making processes and outcomes.

Methods: A case study design was adopted in which events, stakeholders and issues associated with the policy review were described from data generated from interviews and documentary sources. A content-analysis tool is being used to critically analyse textual data. Concepts in the text are being identified and relationships among the policy concepts, stakeholders and processes are being mapped.

Findings: The analysis of data associated with the policy review is revealing a pattern of relationships among stakeholders, processes and concepts around shared values, beliefs and interests towards food and health. Broader food regulation contexts have influenced the decision-making environment. The pattern of relationships shares common characteristics with Sabatier’s ‘Advocacy Coalition Framework’ theoretical explanation of policy-making.

Conclusions: The study findings have implications for health claims policy and practice in Australia. As a case study of evidence in food and nutrition policy-making, this research highlights the role of competing interests, beliefs and values in evidence interpretation. Challenges are identified in undertaking food policy research.

Environmental marketing claims : consumer interpretation and policy implications

Environmental claims communicate the concept of green brands. The purpose of this paper is to examine if environmental claims yield satisfactory results. Secondly, what policy measures would best encourage the adoption of environmental claims by businesses? Finally, how should businesses address practical and theoretical implications?The results suggests that in order to avoid misleading consumers, policy makers need to evaluate the public’s understanding of the meaning of claims, disallow the use of nonstandard claims by businesses, establish an education program and mandate their usage. There is also an indication that the usage of recognisable third party environmental labelling may be a more reliable.

Painful wrench for a European mind : land claims and representations of history and aboriginal tradition in the Darwin hinterland

The first longitudinal study of the way the statutory recognition of Aboriginal traditional rights to land has affected Aboriginal groups in the north western Northern Territory. An interdisciplinary approach is used drawing on methods from both history and anthropology.

Towards the improved treatment of generalization of knowledge claims in IS research : drawing general conclusions from samples

This paper presents a framework for justifying generalization in information systems (IS) research. First, using evidence from an analysis of two leading IS journals, we show that the treatment of generalization in many empirical papers in leading IS research journals is unsatisfactory. Many quantitative studies need clearer definition of populations and more discussion of the extent to which ‘significant’ statistics and use of non-probability sampling affect support for their knowledge claims. Many qualitative studies need more discussion of boundary conditions for their sample-based general knowledge claims. Second, the proposed new framework is presented. It defines eight alternative logical pathways for justifying generalizations in IS research. Three key concepts underpinning the framework are the need for researcher judgment when making any claim about the likely truth of sample-based knowledge claims in other settings; the importance of sample representativeness and its assessment in terms of the knowledge claim of interest; and the desirability of integrating a study’s general knowledge claims with those from prior research. Finally, we show how the framework may be applied by researchers and reviewers. Observing the pathways in the framework has potential to improve both research rigour and practical relevance for IS research.
