A Mobile Phone App for the Provision of Personalized Food-Based Information in an Eating-Out Situation: Development and Initial Evaluation

Background

Increasing pressure from governments, public health bodies, and consumers is driving a need for increased food-based information provision in eating-out situations. Meals eaten outside the home are known to be less healthy than meals eaten at home, and consumers can complain of poor information on the health impact and allergen content of meals eaten out.

Objective

This paper aimed to describe the development and early assessment of a mobile phone app that allows the provision of accurate personalized food-based information while considering individual characteristics (allergies, diet type, and preferences) to enable informed consumer choice when eating out.

Methods

An app was designed and developed to address these requirements using an agile approach. The developed app was then evaluated at 8 public engagement events using the System Usability Scale (SUS) questionnaire and qualitative feedback.

Results

Consideration of the literature and consultation with consumers revealed a need for information provision for consumers in the eating-out situation, including the ability to limit the information provided to that which was personally relevant or interesting. The app was designed to provide information to consumers on the dishes available in a workplace canteen and to allow consumers the freedom to personalize the app and choose the information that they received. Evaluation using the SUS questionnaire revealed positive responses to the app from a range of potential users, and qualitative comments demonstrated broad interest in its use.

Conclusions

This paper details the successful development and early assessment of a novel mobile phone app designed to provide food-based information in an eating-out situation in a personalized manner.

Implicit Messages Regarding Unhealthy Foodstuffs in Chinese Television Advertisements: Increasing the Risk of Obesity

Previous studies indicated that television (TV) advertising is associated with higher rates of obesity. The rate of obesity and overweight continues to rise in mainland China, bringing into question whether TV advertising to young audiences might be partly to blame. This study investigated messaging delivered through TV advertisements regarding healthy and unhealthy foodstuffs. A total of 42 major food brands and 480 advertisements were analysed for content in this study. The results showed that the majority of TV spots advertised products with poor nutritional content and had a potential to mislead audiences concerning products' actual nutritional value. The tactics of repetition and appeals of premium offerings on food brands have a potential to influence the purchase intentions. Additional qualitative observation involving the social bond, social context and cultural factors pertaining to mood alterations were highlighted. The discussion addressed product attributes reflected by culture and the implicit messages of marketing claims may increase the risk of obesity. Thus, public health policymakers and researchers were encouraged to act urgently to evaluate the obesity risks of unhealthy food advertised in the media and to support healthy foods.

Reducing calories, fat, saturated fat, and sodium in restaurant menu items: Effects on consumer acceptance

OBJECTIVE

To assess consumer acceptance of reductions of calories, fat, saturated fat, and sodium to current restaurant recipes.

METHODS

Twenty-four menu items, from six restaurant chains, were slightly modified and moderately modified by reducing targeted ingredients. Restaurant customers (n = 1,838) were recruited for a taste test and were blinded to the recipe version as well as the purpose of the study. Overall consumer acceptance was measured using a 9-point hedonic (like/dislike) scale, likelihood to purchase scale, Just-About-Right (JAR) 5-point scale, penalty analysis, and alienation analysis.

RESULTS

Overall, modified recipes of 19 menu items were scored similar to (or better than) their respective current versions. Eleven menu items were found to be acceptable in the slightly modified recipe version, and eight menu items were found to be acceptable in the moderately modified recipe version. Acceptable ingredient modifications resulted in a reduction of up to 26% in calories and a reduction of up to 31% in sodium per serving.

CONCLUSIONS

The majority of restaurant menu items with small reductions of calories, fat, saturated fat, and sodium were acceptable. Given the frequency of eating foods away from home, these reductions could be effective in creating dietary improvements for restaurant diners.
