Ms Nienke de Vlieger
Born and raised in the Netherlands, Nienke de Vlieger started university at the Roosevelt University College in Middelburg, the Netherlands. Here, she pursuit multiple interests and majored in Psychology, while minoring in Ecology and Anthropology. Even though she had opportunities to continue her education in any of these fields, it was nutrition that had grabbed her attention throughout her Bachelor years. Nutrition and diet had developed from a merely personal interest to a longing for a deeper nutritional understanding and ambition to commit herself to the fight against overweight and obesity. She therefore completed the 2-year Master Nutrition & Health at the highly regarded Wageningen University in the Netherlands. A 4-month internship at the University of Newcastle in Australia introduced her to the world of research and particularly education as a way of health interventions. It was not long until she returned to Newcastle to start a PhD focussed on nutrition education for children. She has since published a paper on her Master internship research and has co-authored several other papers in the field of nutrition. She is scheduled to finish her PhD in 2019.

Issue addressed Portion size guidance strategies have been suggested as an important component of weight management; therefore, the Health Star Rating (HSR) front-of-pack labels could influence consumers' portion-size decisions. However, this has not been investigated to date. This study aims to evaluate whether presenting energy content information and HSRs influences portion size self-selection of specific foods and meals. Methods Adults were randomly assigned to one of three experimental groups in this randomised controlled experiment. Each participant was given either a kJ/100g food label or a HSR label, or was given no information on nutrient composition. They were then asked to serve themselves an adequate portion of breakfast cereal (Kellogg's Nutri-Grain), fruit salad and chocolate, plus a three-component meal (chicken, fries and mixed vegetables). Portion serves and meal weights were compared between each experimental group using ANOVA and the discretionary foods were also compared with the Australian Guide to Healthy Eating (AGHE). Results Neither the kilojoule nor HSR information influenced the self-served portion size of foods or meal components. Mean self-served portion size of the discretionary foods were significantly greater than the standard serving sizes as specified in the AGHE. Conclusion Although food labels have the potential to assist consumers in making product choices, this study indicates that presenting nutrition information does not affect portion size decisions in young adults. So what? Strategies that assist consumers to choose appropriate portion sizes should be developed as a weight management tool.

© The Authors 2016. Nudging or 'choice architecture' refers to strategic changes in the environment that are anticipated to alter people's behaviour in a predictable way, without forbidding any options or significantly changing their economic incentives. Nudging strategies may be used to promote healthy eating behaviour. However, to date, the scientific evidence has not been systematically reviewed to enable practitioners and policymakers to implement, or argue for the implementation of, specific measures to support nudging strategies. This systematic review investigated the effect of positional changes of food placement on food choice. In total, seven scientific databases were searched using relevant keywords to identify interventions that manipulated food position (proximity or order) to generate a change in food selection, sales or consumption, among normal-weight or overweight individuals across any age group. From 2576 identified articles, fifteen articles comprising eighteen studies met our inclusion criteria. This review has identified that manipulation of food product order or proximity can influence food choice. Such approaches offer promise in terms of impacting on consumer behaviour. However, there is a need for high-quality studies that quantify the magnitude of positional effects on food choice in conjunction with measuring the impact on food intake, particularly in the longer term. Future studies should use outcome measures such as change in grams of food consumed or energy intake to quantify the impact on dietary intake and potential impacts on nutrition-related health. Research is also needed to evaluate potential compensatory behaviours secondary to such interventions.
