My feed is what I eat? A qualitative study on adolescents' awareness and appreciation of food marketing on social media.

Background: Adolescents spend much of their time online and hence are exposed to a lot of non-core (energy-dense, nutrient-poor) social media food marketing (SMFM). This may influence their dietary choices and health. This present study aimed to investigate adolescents' perceptions towards SMFM; that is, their recognition and appreciation of SMFM.

The Nutri-Score algorithm: Evaluation of its validation process.

The Nutri-Score front-of-pack label, which classifies the nutritional quality of products in one of 5 classes (A to E), is one of the main candidates for standardized front-of-pack labeling in the EU. The algorithm underpinning the Nutri-Score label is derived from the Food Standard Agency (FSA) nutrient profile model, originally a binary model developed to regulate the marketing of foods to children in the UK. This review describes the development and validation process of the Nutri-Score algorithm.

Making sense of adolescent-targeted social media food marketing: A qualitative study of expert views on key definitions, priorities and challenges.

Traditional food marketing stimulates adolescents' consumption of energy-dense, nutrient-poor foods. These dietary behaviours may track into adulthood and lead to weight gain, obesity and related non-communicable diseases. While social media use in adolescents has proliferated, little is known about the content of food marketing within these platforms, and how this impacts adolescents' dietary behaviours.

The influence of a front-of-pack nutrition label on product reformulation: A ten-year evaluation of the Dutch Choices programme.

Front-of-pack (FoP) labels are regarded as helpful tools to stimulate healthier product reformulation as they are based on nutrient criteria that products should comply with in order to obtain the label. Some FoP labelling programs revise criteria periodically. This is the first study investigating the impact of criteria revisions on product compositions over time.

Differences and Similarities between Front-of-Pack Nutrition Labels in Europe: A Comparison of Functional and Visual Aspects.

Many different front-of-pack (FOP) nutrition labels have been introduced worldwide. To continue the debate on the most effective FOP labels for increased consumer health, full comprehension of their visual and functional features is relevant. This paper compares and provides an overview of all FOP labels currently in practice or in preparation in Europe, by means of the visually oriented Funnel Model.

Trends in Food and Beverage Portion Sizes in Australian Children; a Time-Series Analysis Comparing 2007 and 2011-2012 National Data.

In 2011-2012 approximately 26% of Australian children aged between 5-17 years were reported to be overweight or obese. Furthermore, the increase in prevalence of overweight and obesity among US children parallels reported increases in energy intake and portion sizes of common foods, leading to the recognition that availability of larger portion sizes contributes to the rise in overweight and obesity prevalence. Thus, the aim of this time-series analysis was to investigate whether selected food portion sizes in Australian children aged 2-16 years changed between 2007 and 2011-2012.

Nudging consumers towards healthier choices: a systematic review of positional influences on food choice.

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.
