An exploration of the influence of food labels on South African consumers' purchasing behaviour

New labelling legislation in South Africa is expected to help consumers sustain a healthy lifestyle through the food choices they make. This study was undertaken to explore a sample of South African consumers' reasons for reading labels and the influence of food labels on their purchasing behaviour. The study was conducted using focus group discussions held with label reading consumers in Potchefstroom in the North West Province of South Africa. Findings suggested that these participants read food labels to assess the nutritional value, personal benefits, health attributes and product quality. Various purchasing influences were also identified, suggesting that consumers are in some cases motivated by food labels to purchase a product, or may be unresponsive to the label or indifferent by being aware of the information but not reluctant to buy a product that does not indicate essential information. Several indirect consideration factors such as situational factors (e.g. family), extrinsic (e.g. price) and intrinsic (e.g. taste) may contribute to the purchasing behaviour of some consumers. These findings are useful to propose a perceptual model of the way in which food labels influence purchasing behaviour of a sample of South African consumers and explain the role of food labels in the purchasing decision of label‐reading consumers. This information is especially significant for new packaging and labelling initiatives as it highlights the reasons why label‐reading South African consumers read label information.     

Estimating the effects of nutrition label use on Canadian consumer diet‐health concerns using propensity score matching

The overarching goal of nutrition labelling is to transform intrinsic credence attributes into searchable cues, which would enable consumers to make informed food choices at lower search costs. This study estimates the impact of nutrition label usage on Canadian consumers’ (n = 8,114) perceived diet‐health concerns using alternative propensity score matching (PSM) techniques. We apply a series of tests and sensitivity analyses to overcome issues of endogeneity and selection bias frequently found in studies of diet‐health behaviour and to validate the impact of exposure to nutrition facts labels for users vs. non‐users. Our results support the notion that consumer uncertainty and related food‐health concerns are linked to their information behaviour, but not in straightforward manner. Dominant subjective food attributes, such as taste, convenience and affordability, may in fact outweigh the benefits of information about healthier, alternative food choices. In order to change dietary health behaviour, food manufacturer and policy makers alike need to adopt communication instruments that better account for differences in preferences, shopping habits and overall usage patterns of nutrition labelling information.     

A conceptual framework for analyzing consumers' food label preferences: An exploratory study of sustainability labels in France,Quebec, Spain and the US

In a qualitative study of 375 consumers in France, Quebec, Spain and the US, respondents are asked to choose between pairs of actual food labels and to describe the reason(s) for their choice. The food labels included sustainability labels (eco‐labels, Fair Trade, origin) as well as product attribute (e.g. quality, kosher) and health/nutrition labels. Respondents' reasons were coded in the original language using the same coding system across all four nations to examine their preferences for label message, design and source. We also examined the role of consumers' values, beliefs and experiences on their label choices. The coding system was drawn from a review of theoretical and empirical literature and provides a conceptual framework we call the Label Consumer Interaction model for evaluating consumers' food label preferences. Although this is case study, the results point to substantial differences across nations in terms of preferred labels, as well as the rationale for their choice in terms of attributes of the labels and consumer characteristics.     

Usage and understanding of food labels among Lebanese shoppers

Food labelling is a population‐based approach to health education that enables consumers to make better choices by providing information at the point of purchase. This study aimed to assess the food label usage and understanding and factors affecting them among Lebanese supermarket shoppers. A cross‐sectional study was conducted among 748 supermarket shoppers in Lebanon between December 2013 and February 2014 using a pre‐coded structured questionnaire. About 29.3 of the shoppers check the food labels every time they buy a food product and 15.7% never do it. Shoppers who do not read food labels identified the long time needed in reading them as top reason (34.9%), while 9.8% answered that they do not understand them. About 55.4%of the surveyed shoppers read the food labels at the supermarkets. About 44.4% of participants agreed that reading food labels is very important, while 30.3% read the food labels depending on the purchased product. Then 19.4% of participants complained that food labels contain too much information and 13.8% claimed that food labels are difficult to understand. About 60.3% think that food labels have helped people in changing their eating habits, while health and nutrition claims affected the product selection among 59.8% of participants. The food label knowledge score average was 63.1%. Older, obese shoppers having kids, suffering from chronic illness or allergies, following a specific diet and residing in big cities scored significantly (p < .05) higher. The low knowledge score necessitates the nutrition education on how to read and use the food labels. Groceries would be the perfect place to reach out mass consumers.     

Seeing Is Not Believing: Perceptions of Date Labels over Food and Attributes

ABSTRACT

This study investigates consumers’ perceptions of date labels (“Best by” and “Use by”) between different food items (spaghetti sauce and deli meat) and across different attributes (nutrition, quality, safety, and taste). We collected data from experimental auctions and a survey held in cities located in two different regions of the United States. Previous research suggests that confusion over date labels contributes to waste. Thus, we ask respondents to indicate the meaning of date labels for products over attributes. Overall we find that respondents have differing conceptions of date labels by product and over attributes, which reflects confusion over the date labels. However, the differences, while statistically significant, are not large enough to suggest a reversal of perception from agreement to disagreement in the meaning of the date label for specific attributes. The findings question the effectiveness of a two-date label regime to reduce food waste.     

Consumers' perceptions of individual and combined sustainable food labels: a UK pilot investigation

Consumers are faced with an increasing number of sustainable food labels. These different labels may be complementary or add to the increasing competition of product information in consumers' minds. We investigate: (1) the perceptions that consumers in the UK have about sustainable labels vs. other labels, such as origin or nutrition labels; and (2) consumers' reactions to combinations of different sustainable labels. Overall, the findings from two focus groups conducted in the UK indicate that consumers have positive perceptions of organic and fair trade labels but tend to be sceptical about unfamiliar labels and general claims such as ‘climate friendly’. The results also indicate the importance of familiarity, trust and fit between combinations of labels as well as between associating a label with a brand. While the combination of certain labels can enhance the value of a food product, this study also indicates that other label combinations (e.g. private and sustainable label) can detract from a label's value. Implications and recommendations are suggested for managers to counter the image of greenwashing, and for policy makers to facilitate sustainable food choices.     

Are nutrition labels useful for the purchase of a familiar food? Evidence from Chinese consumers�� purchase of rice

Nutrition labeling has been accepted by Chinese consumers as an information source to learn about food quality and safety. This paper uses Chinese consumers’ rice purchase as an example to study how consumers use food nutrition labels to make purchase decision of a familiar food product. The goal is to understand how consumers seek information from the labels to make purchase when extensive experience with the food has been developed. Survey data from 400 random respondents in Beijing were analyzed using an empirical framework and a Mont Carlo integral econometrics model. We find that more than 50% of the consumers in Beijing have heard of food nutrition labels in general, 36.50% carefully use label information even if they are familiar with the food, and nearly 70% consider mandatory food nutrition labels as beneficial. Those who are more knowledgeable about rice nutrition labels are more likely to use the labels when purchasing rice, no matter how familiar they are with the product. Frequent users of nutrition labels are more likely to consider food mandatory nutrition labels as beneficial. This study suggests that consumers still use the label information to reassure the quality and safety of food despite a history of consumption.     

Effects of shared characteristics between eco-labels: A case for organic and local food

Food labels are created to reduce information asymmetry and help consumers make better food choices. However, the labels may have unanticipated effects, especially when they share common characteristics that may introduce confusion in making food choices. This study investigates how perceived relationships between different food labels may affect the price premiums of organic and local attributes for milk and fresh strawberries. Results show that the impacts of perception vary by product and label, and different food labels could positively affect price premiums on organic and local products. Results provide policy implications for better labeling and educational programs to reduce inadvertent confusion and improve consumer decision-making.     

Use and knowledge of food labels of shoppers in a city with a high proportion of heart disease

This study aimed to assess consumers’ use and understanding of food labelling and the improvements that they would like. Systematically selected supermarket shoppers were interviewed using a questionnaire. Data showed that the use of food labels was low. Among those who read food labels, at least occasionally, use‐by‐date was the most reported information looked at. Understanding of the content of five nutrients on a standard food label provided was poor. Although a high proportion of participants claimed to have no problem with the current format, those who had problems wanted food labels that were ‘bigger’, ‘highlighted’ or written in ‘plain English’. These results suggest that before improved food labels can have an impact on consumers’ food choice, strategies to encourage shoppers to read them are needed.     

The effects of traffic light labels and involvement on consumer choices for food and financial products

Traffic light (TL) labels that inform consumers regarding product safety have received increasing attention in different fields. Behind the background of behavioural economics, this paper presents the results of a split‐sample choice experiment conducted in Germany to evaluate the impact of TL labelling on purchases of food and financial products. We hypothesize that consumers experience different levels of involvement with these two types of products, leading to different recommendations regarding the use of TLs. The results show that TLs affect consumer purchases of both product groups by focusing their attention on specific product attributes. For food, whereas the low‐fat attribute has no significant impact on food choices that do not include TLs, this attribute has a positive impact on choices once it is signalled with a TL label. The positive evaluation of the organic production attribute of a food product without a TL decreases when the same product is labelled with a TL. In the case of financial products, TLs significantly reinforce the impact of all characteristics on choice probability. TLs also generate a halo effect with regard to return variance. Although consumers demonstrate different levels of involvement for the two types of products, involvement does not always impact the evaluation of attributes. Compared with less involved consumers, more involved consumers exhibit more heterogeneous evaluations of the return variability attribute in the case of the financial product and the organic attribute in the case of the food product.     

Effect of knowledge on decision making in the context of organic cotton clothing

This research was designed to study whether consumer knowledge on organic cotton and relevant issues influences attitude toward and price acceptance of organic cotton clothing. The effect of consumer knowledge was also studied on the way consumers use product label information in purchasing organic cotton clothing. An online survey was developed to measure the variables including experimental choice‐based conjoint models for mandatory and auxiliary label specifications. Four hundred ninety‐eight people completed the survey. The results indicated that moderately and highly knowledgeable participants were more willing to buy organic cotton clothing at higher price points and they had more positive attitudes toward organic cotton clothing than low knowledgeable participants. The results suggest that differentially knowledgeable consumers may attend to different types of information provided on product labels to evaluate organic cotton apparel products. Providing product‐related information on product labels is essential; however, providing additional information on the benefits of using organic cotton and socially responsible business practices may improve consumers’ knowledge and acceptability of organic cotton apparel products.     

Nutritional labelling information: Utilisation of new technologies

Abstract

The increase in food-related diseases in society has led to a variety of public policy and private sector initiatives, such as the use of nutritional labels. Although nutritional labels have been shown to be broadly effective in terms of informing food choice, their influence is moderated by a variety of factors, such as how information is conveyed and processed by consumers. Recent advances in technology might overcome these limitations. Using a choice experiment, this paper examines consumer preferences for alternative technological devices that may aid consumer processing of nutritional information on food packaging. The results show which attributes of the technology consumers prefer, and identifies three distinct segments of consumers (‘information hungry innovators’, ‘active label readers’, and ‘onlookers’), and differences between them in relation to their preferences, demographics, and psychographic characteristics. The identification of segments is a novel aspect of this research, and highlights the importance of finding more customised solutions to the communication of nutritional information – an issue to which technology can contribute.     

Low‐literate consumers' use of clothing labels amidst personal and product related challenges

Low‐literate consumers experience various challenges in the marketplace. This quantitative study focused on low‐literate female consumers' use of clothing labels amidst personal and product‐related challenges in the marketplace. An interviewer‐administered questionnaire was used among black African female consumers (n = 450) with literacy levels ranging from Grades 5 to 8 (on average, 11–14 years old), residing in the Emfuleni Local Municipality area, Gauteng, South Africa. Personal challenges experienced involved reading and numeracy skills, as well as concrete and pictographic thinking. Although respondents indicated that they read and understand clothing labels, results revealed problems experienced when attempting to use the information provided. Their numeracy skills were average and related abstract thinking skills were fair. Product‐related challenges were related to the format of labels, care‐label knowledge and evaluation of clothing quality. Respondents' preference for symbolic and graphic presentation of size format provided evidence of pictographic thinking. Care label understanding was poor, and clothing products were evaluated concretely. Some of the older respondents were inclined to follow the peripheral route of elaboration when reading clothing‐label information. We conclude that low‐literate consumers' use of clothing label information can improve if provided in a format that they can read and understand.     

Information search behaviour and its determinants: the case of ethical attributes of organic food

Daily decisions on food purchase are known to be undertaken using limited information search. However, when confronted with ‘ethical’ products, consumers often become more involved, and this results in a more extensive search for information. This research focuses on the information search behaviour of European consumers with regard to ethical attributes like animal welfare or environmental aspects of organic food by means of an Information Display Matrix. Row‐wise information search by product characteristics (attributes) was widely preferred over information search by product alternatives (column‐wise). Therefore, information (e.g. in the Internet) should increasingly be provided by attributes. The majority of consumers use simplifying and selective search strategies when looking for information on organic food with additional ethical attributes. Consumers tend to start information search in the top, left hand corner and move towards the bottom, right hand corner. Thus, principal attributes should be placed in the upper left corner and be followed by the next most important and so on when presenting information on an array of different products. Our results show that information search patterns of consumers depend on socio‐demographic characteristics like gender and age and, to a lesser extent, also on attitudes regarding environmental or social aspects of food production. Thus, marketers, particularly those using the Internet, should revise their systems of information provision and focus increasingly on consumers' needs.     

The effect of information overload on consumer choice quality in an on‐line environment

As more and more consumers become part of the net population, retailers and manufacturers as well as dot‐com storefronts are touting consumers by providing an ever‐increasing amount of product information. Their long‐term survival and profitability may be determined by how much and how well their product information is presented to and processed by the consumers. By combining both the traditional and structural approaches to the information‐overload phenomenon, this study investigates the impact of Web site information on consumer choice and psychological states in an on‐line environment. Varying the number of alternatives and attributes (traditional measure) and attribute level distribution across alternatives (structural measure), this study asks subjects to choose the best (dominant) CD player in a given set. Their subjective states such as satisfaction, confidence, and confusion are also measured. Results show that the number of attributes and attribute level distribution are good predictors of the effect of information overload on consumer choice. In addition, the study finds that on‐line information overload results in less satisfied, less confident, and more confused consumers. Implications and suggestions for future research are provided. © 2004 Wiley Periodicals, Inc.     

Food choice: student consumers' decision‐making process regarding food products with limited label information

Food label information theoretically facilitates consumer decision‐making and food choice, but the extent to which consumers actually use this information during decision‐making is a subject of considerable debate. Therefore, this study focused on the importance of label information in student consumers' decision‐making process when exposed to limited label information food in a cafeteria environment. Because of a paucity of research in this area, a qualitative research approach that was exploratory in nature was used, accompanied by semi‐structured interviewing and a vignette. Undergraduate students from the North‐West University, Potchefstroom Campus, in South Africa served as the target population. The findings suggest that internal and product‐related strategies are applied when food choices are made whereby the importance of label information only features in the latter strategy. Student consumers with a label interest were more inclined to use label information strategies in the absence of complete label information to base food choice on. Those with a lack of label interest made use of alternative strategies using product and personal‐related information, such as freshness and product knowledge to make decisions. The decision‐making process was more complex because of insufficient label information and product appearance, and thus previous experiences and habitual purchasing became more important to participants. Student consumers should be supported to make healthier food choices through food manufacturers supplying cafeteria products with more complete label information and by providing students with the knowledge to use label information correctly through educational programmes.     

Facts-up-front: should food companies follow the FDA or industry label format? The effects of combining virtue and vice information on consumer evaluations

This research examines consumers’ processing of Facts-up-front food labels as implemented by the Grocery Manufacturers Association (GMA). Facts-up-front labels include both positive (virtues) and negative (vices) nutritional icons. The processing and relative efficacy of Facts-up-front labels are compared to the original FDA proposal of front-of-pack labels which only included vices. The results suggest heuristic processing of these labels, whereby consumers consider the nutritional icons on the front-of-pack labels similar to affective stimuli. The addition of virtues alongside vices on the label has a compensatory effect, i.e., the food item is evaluated as healthier when there are both virtues and vices on the label compared to when there are only vices. Such heuristic processing of Facts-up-front labels that allows nutritional virtues to compensate for nutritional vices has the potential for consumers evaluating harmful foods as relatively “healthy” thus compromising consumer well-being. These findings illustrate the importance of empirically testing changes to nutritional labels before large scale implementation. Since consumers process front-of-pack labels heuristically and not cognitively, it is not surprising that nutritional literacy does not moderate the effects of label design on healthiness evaluations. Furthermore, the order of the negative and positive information on Facts-up-front labels also has no effect.

     

Why Might Organic Labels Fail to Influence Consumer Choices? Marginal Labelling and Brand Equity Effects

An organic label offers a market signal for producers of organic food products. In Western economies, the label has gained high recognition, but organic food still represents a small part of total food consumption, which raises questions about the label's efficacy. By considering organic labels as a signal of quality for consumers, this article studies how this signal interacts with brand signals when both are visible to consumers, applying a cobranding framework. This research examines the moderating effect of the brand on organic label effects. In a 2 × 2 experimental design using real consumers (N = 122) in a shopping context, it found that, depending on brand equity, the marginal effect of organic labelling information in terms of perceived product quality varies. In particular, when brand equity is high (low), the organic label appears less (more) effective. However, regardless of the brand equity level, an organic label makes the environmentally friendly attribute salient, which has a positive impact on perceived quality. Pertinent implications for marketing and public policy are discussed.
