The purpose of this research is to investigate how biofortification claims impact consumer food taste inference and purchase intention. Based on the halo effect, the authors propose that food products with biofortification claims are inferred to taste better than regular foods. Due to this inference, biofortification claims subsequently improve purchase intention.

To examine these predictions, the authors conducted three between-subject design lab experiments featuring three staple foods: corn soup (β-carotene biofortification claim present or not), cooked rice (zinc biofortification claim present or not) and uncooked rice (zinc biofortification claim present or not). Participants were randomly assigned to one of two bioproduction claim conditions (present vs absent). Then, taste inference, purchase intention, consumer characteristics and confounding variables were measured.

In Experiment 1, the results showed that biofortification claims indeed appeared to evoke a heuristic halo effect, in which foods with biofortification claims were inferred to taste better than regular food. In Experiment 2, the results showed that participants had more intention to purchase foods with biofortification claims than regular food. The mediation effect of taste inference between biofortification claims and purchase intention was examined. In Experiment 3, the data further showed that this halo effect was more pronounced when consumers held a higher preference (vs lower preference) for the enriched nutritional element.

Biofortification claims have commonly been viewed solely as information about nutrition value for consumers. However, little is known about how biofortification claims impact hedonic consumer expectations. In this paper, the authors find that biofortification claims alone can impact consumer food taste inference, as nutritional information is not related to actual food taste. These findings extend the authors’ understanding of the psychological mechanism behind consumer attitudes towards biofortification.

A product colour plays an important role in consumers’ preferences. The purpose of this paper is to highlight the impact of the three-dimensional character of colour (brightness, saturation and vividness) on children’s behaviour towards a food product and as a source of well-being.

Two experiments were conducted. Study 1 was conducted with 62 children and used four visuals of syrup presenting two colours (red/green) and two variations of vividness (vivid/dim). Study 2 was conducted with 70 children and used four pictures of stewed apples and four pictures of pouches to test the influence of each dimension of colour on children’s preferences for the product and the product packaging.

Results show that the three-dimensional character of colour plays an important role in children’s gustatory inferences and well-being.

The study is restricted to one food product (in each study) habitually consumed by children. Other products could be investigated to show how colour can contribute to children’s well-being.

The paper addresses the issue of well-being as a potential brand-positioning element.

The paper suggests new avenues to use the brightness/saturation or vividness of a product or packaging colour as a potential element to arouse positive sensations that generate children’s well-being even when the product is not a preferred one.

This works initiates creative thinking concerning the impact of a product colour on children consumers.

Building upon humans’ trichromatic vision systems, dual-process theory and halo effects, this paper aims to examine the effects of red and green color brightness of food pictures on customers’ evaluations and purchase intention of restaurant food.

The proposed hypotheses were tested across three experimental designed studies on a total of 575 participants. Multilevel analysis, analysis of variance and multivariate analysis of variance were applied for data analysis.

This paper provides empirical evidence of the effects of red brightness and green brightness on customers’ affective and cognitive evaluation of food and purchase intention in Study 1. Study 2 validates the effects of red and green brightness on food evaluation with the presence of nutrition information. Study 3 further elaborates on the halo effects of color brightness on customers’ favorable intentions to patronize a restaurant and willingness to pay for a meal in a controlled lab experiment.

One main limitation is that this paper focuses on unveiling the role of color brightness and does not consider other picture properties, which opens an avenue for future research.

This paper includes implications for food promotion and management of customers’ experience via food pictures.

This paper is one of the first attempts to reveal the effects of red and green brightness of food pictures on customers’ food evaluation and food consumption behavioral intentions.

There are initiatives proposed in a number of states that would mandate calorie information disclosures from restaurant chains on their menus and menu boards. Such labeling laws have already been passed in New York City, Philadelphia, Seattle, and the states of Massachusetts and California. This paper aims to analyze whether nutrition disclosures are necessary for the average consumer to identify meal calorific content, to address consumer motivation to attend to nutrition labels, and to assess whether such labeling efforts may influence consumers' subsequent behaviors.

To address issues related to nutrition labeling of chain restaurants, a food court field study and a longitudinal quasi‐experiment were conducted.

The results indicate that as meal calorie, fat, and sodium levels increase, the level of consumers' underestimation of calories and nutrients increases. Consumers generally need the help of nutrition labeling to identify the content of menu items. Furthermore, there is an effect of perceived item healthfulness on repurchase intentions, and this effect is strengthened by disclosure of nutrition information. However, even after nutrition disclosure, the strength of the effect of taste perceptions on repurchase intentions dominates the effect of meal healthfulness.

This paper identifies that consumers do not have adequate nutrition knowledge when it comes to foods consumed outside the home. Relative comparisons among alternatives may be made, but consumers do not understand the absolute nutritional value of foods consumed. The authors identify that nutritional labeling does influence healthier consumer decisions. However, the key variable is consumer motivation. Only for the most nutritionally motivated consumers will this influence of healthfulness withstand the influence of taste.

This paper aims to elucidate some of the complexity around food consumption by drawing from neuroscience research of food as a motivated choice (i.e. a neurobehavioral process sensitive to dopaminergic response to food and environmental cues such as marketing). The authors explore the single and compounded effect of the motivational salience of food’s intrinsic reinforcing value tied to its sugar content and that of two marketing food cues, price and in-store display, on actual consumer purchase behavior.

The authors test the above hypotheses in two perceived “healthy” product categories with a wide distribution of sugar content. The authors estimate a within-category model using three years of retail transaction data to test the effect on weekly sales.

The authors confirm the single effect of each of food’s and marketing cues’ motivational salience as well as their compounded effect with high-motivational-salience food being less price elastic and more susceptible to in-store display activities.

This research highlights the need to complement current reliance on unhealthy/healthy perception with finer grained objective evidence linked to the formulation of the food itself and the marketing applied to them.

The present study findings may help marketing managers and policymakers develop better targeted pricing and display strategies for low- and high-motivational-salience food, attempting to strike a better balance between consumer welfare and commercial performance.

This paper is one of the few that links real-world market outcomes to predictions derived from a unique combination of consumer neuroscience and neurobiology of food, advancing data-driven decisions.

This paper aims to investigate inferences consumers make about organic and all-natural labeled products in both food and non-food contexts using the health halo effect as a theoretical foundation.

This paper uses three experiments to test the effects of organic and all-natural labeling across three product types, food, personal hygiene and household cleaning, while controlling for environmental attitudes.

The results of the experiments in the context of food, personal hygiene and household cleaning products suggest that both organic and all-natural labeling produce halo effects. Distinct findings are presented across the three product types.

Findings indicate that consumers may make unwarranted inferences about both organic and all-natural labeled products and demonstrates that the health halo effect is a potentially robust phenomenon, pervasive across a diverse array of products. This research used a crowdsourcing platform for sample recruitment. Future research should validate the results of these experiments with other sample types.

This research suggests that consumers may make similar unwarranted inferences for diverse products bearing organic and all-natural labels. These inferences are particularly intriguing given the differing regulatory requirements for the labels

Organic and all-natural labels are ubiquitous in both food and non-food products. However, research on either label primarily exists in a food context and has not directly compared the labels. Understanding the inferences consumers make based on the labels across product types is imperative for both marketing and public policy.

The mechanism by which organic labelling affects consumers’ willingness to pay (WTP) for wine is not yet fully understood. Organic labelling not only transports information about environmental benefits, but may also influence consumers’ perceptions of quality and taste. The purpose of this paper is to separate the information effect from the perception effect of an organic label on WTP.

Taste and quality perceptions of 110 German consumers and their WTP for white and red wines were collected in a second-price auction in conjunction with a blind tasting. Each measure was recorded under two experimental conditions: with and without organic labelling. Serial mediation analysis is used to identify the information and perception effect of an organic label on WTP. A moderating effect of commitment to organic consumption is considered.

Wines marketed as organic are perceived as tastier and of higher quality and value. The organic labelling effect is stronger for committed organic consumers. Mediation analysis confirms perceived better taste as a key driver for WTP, especially for less committed organic consumers. The findings highlight perceptions of wine quality as the main mediator through which organic labelling affects WTP for red wine and for committed organic consumers.

This paper adds to the literature by decomposing the signalling mechanism of organic labelling and by emphasising the role of individual characteristics in determining its magnitude and pathways. Implications from a marketing and wine industry’s perspective are discussed.

This paper aims to examine the effect of proximal (versus distant) depiction of food products within an advertising or online context on consumer responses across food types (indulgent versus non-indulgent) and display formats that lead to a single exposure (e.g. billboard) versus multiple exposures (e.g. online menu).

Five experimental studies, using both implicit and explicit elicitation techniques, demonstrate the effect of proximal food depictions. The paper rules out alternative explanations (portion-size perception and participants’ bodily distance) and controls for several other factors (e.g. visual crowding, body-mass index, dietary restrictions, etc.)

The studies find that proximal food pictures are implicitly associated with tastiness more for indulgent (vs non-indulgent) foods; lead to higher purchase intention for indulgent food upon a single exposure driven by enhanced perceived tastiness; and evoke satiation upon multiple exposures.

This research identifies the effect of spatial proximity of food depiction on consumer responses using different stimuli. Future work could explore the effects in alternate consummatory contexts.

The findings provide clear instructions to marketers and policymakers on how to tailor consumer responses using spatial distance in depiction of food products, depending on the food type and display format. Understanding the effect of visual food cues will help policymakers devise strategies to counter over-consumption, which increases the risk of non-communicable diseases and reduces consumer well-being (SDG 3, United Nations).

Introducing a novel pictorial cue (i.e. the spatial distance of product depiction), this paper contributes insights to the literature on implicit associations, visual information processing, satiation, over-consumption and food marketing.

This paper aims to offer social marketers an innovative method to promote healthy foods. This method demonstrates the effectiveness of indirect communication in attracting consumers to healthy foods. Further, it aims to offer a way to promote food as healthier with no detrimental effects on its perceived appeal, which are a likely side effect of advertising food as healthy.

Four between-participant lab studies (N = 50, 80, 80, 102) included manipulations of food motion vs stillness and then compared ratings of food freshness, healthiness and appeal using self-report measures.

Motion increases healthiness evaluation. This increase in healthiness evaluation occurs without reductions in food appeal. These effects are mediated by evaluations of freshness. This occurred across three different food types and two mediums (still images and digital videos).

The paper provides an effective tool for social marketers wishing to encourage healthier eating. Specifically, it helps address two problems: low effectiveness of prevalent, information-based appeals to encourage healthy eating; and reduced evaluations of tastiness that normally occur when consumers are convinced food is healthy.

Social marketers can use motion as an effective tool to promote food as healthy. Importantly, this indirect communication avoids the potential pitfall of reduced food appeal. This should help encourage healthier eating. The findings also supports the use of indirect cues as an effective approach to promoting social ends.

Offering a novel, indirect method of enhancing judgments of food healthiness via a simple visual cue. Demonstrating the effect and its underlying mechanism. Providing a way to counter the prevalent “unhealthy = tasty” intuition, a major obstacle to promoting healthy eating. Supporting social marketers’ use of indirect communication to increase the appeal of desirable societal goals. Finally, showing that sensory visual cues can serve as a source of heuristic thinking.

The purpose of this paper is to report the results of a study using photoelicitation interviews to investigate the relationship between the habitualised and unconscious aspects of consumers' food choices, the front‐of‐pack nutrition labelling schemes on food products and the healthiness of their diets.

To this end, photographs of ten German middle‐class families at different stages of the family lifecycle were taken at the point of purchase (during a shopping trip made by the main person responsible for meal planning) and at the point of consumption (during a family meal at home). The paper used selected photographs as stimuli for photoelicitation. The interviews were recorded and analysed using a holistic approach.

Four themes concerning food characteristics, participants' food choices and their healthiness emerged from the data: perceived time pressure at the point of purchase; the relevance of nutrition information for making inferences with regard to the healthiness and tastiness of products; consumers' trust in nutrition information; and their use of this information at the point of purchase or point of consumption.

Photoelicitation interviews allowed us to bridge the gap between researchers and respondents and to study what happens in real‐life situations when consumers go shopping and prepare family meals.

By putting nutrition information on food packaging, especially on the front of the pack, manufacturers and retailers enable consumers to make faster and healthier decisions at the point of purchase – i.e. as long as the consumers notice, understand, trust and like the labelling and use it in making their final decision. Front‐of‐pack labels are of less relevance at the point of consumption.

The paper provides a number of insights into the processes involved in making healthy (or unhealthy) food decisions. It also provides directions for future studies in visual research and in the fields of consumer behaviour, marketing and public policy.
