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.     

Evaluation of food labelling usefulness for consumers

Food labelling is a means of communication between food business operators and consumers, representing an important factor in consumer purchasing decisions. The enforcement of the new food labelling policy is aimed to improve food safety and public health through the mandatory indication of information and nutritional values. To understand the usefulness of the information provided for consumers, a survey was carried out to assess the efficacy of the information presented in food labelling. Principal component analysis was performed to obtain a smaller number of uncorrelated factors regarding the usefulness of food labelling. Results showed consumers usually do not read food labels due to lack of time and excessive information. Additionally, food labelling was observed to be more useful for specific consumer groups, such as, athletes, consumers with health conditions or consumers concerned with a healthy lifestyle. The results of the present study highlight the need of information campaigns by public health authorities to show the importance and advantages of reading food labels as well as the development of essential information which should be quickly and clearly seen and understood by consumers.     

Consumer responses to private nutrition signals

Mandatory labelling of nutrition information with a numerical nutrition facts panel is commonly required for prepackaged food products. Recently, food manufacturers and retailers have developed simplified nutrition signals such as front-of-package labelling (e.g. the Traffic Light label) or retail shelf labels (e.g. Guiding Stars), which provide a more intuitive signal of nutritional content. Using survey data from a sample of consumers from western Canada, this paper examines consumer responses to two private nutrition labelling programs: Guiding Stars and the Traffic Light label. Consumers are more receptive to the Traffic Light label than the Guiding Stars. Ordered probit models explore the factors influencing the likelihood of using these nutrition signals. Trust in the food label, perceived difficulty of using nutrition information, nutrition knowledge, and the importance placed on nutrition influence receptively to these labels. Simplified nutrition labels are likely to complement, rather than substitute for, the existing Nutrition Facts Table.     

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.     

Meat labels: consumer attitude and meat consumption pattern

This paper addressed consumers’ attitude towards food labels and the influence of different aspects of meat labels on beef, poultry and seafood consumption using data from a national survey in the USA. Approximately 70% of the respondents reported that food labels helped in the purchases of beef and other meat products. While 50% thought that the present level of information on meat labels was about right, about 30% thought that it was insufficient. Similarly, 80, 81, 60, and 80% of the respondents thought that it was very important that meat labels contain information regarding nutrition, ingredients, health claim, and production process respectively. Those respondents who thought that nutrition and ingredient information on food labels were very important also thought that meat labels helped them select beef and other meat products. Consumer preferences for nutrition and ingredient information on food labels were positively related with meat consumption frequency.     

Ease of reading of mandatory information on Canadian food product labels

Food product labels present individual product information, safety, nutrition, electronic inventory, container and environmental information, in various formats, languages and images. Some information is mandatory; much is promotional. The food label is an essential tool for regulators of safe food handling, nutrition policy and fair competition. Mandatory information on food labels in Canada is required to be presented in both English and French, readily discernable, prominently displayed and legible. This study examines the ease of finding and reading of mandatory label components on selected Canadian food products. A validated typographical scoring system assessed the lists of ingredients on a purposive sample of 100 food labels representing foods in all groups in Canada's Food Guide. Seven percent of the ingredient lists were easy to read; 26% were difficult to read and 67% were very difficult to read. Well‐educated resourceful readers in consumer focus groups examined food labels for key elements that influence ease of finding and reading information. Focus groups and typographical scoring identified: colour contrast, case, print style, print size, space between the lines, reverse print, organization, justification, type of surface, hyphenation and print reproduction as factors that affect ease of reading. Print that curves around a container, lack of paragraphing or point form organization make reading difficult; text blocks at right angles to each other make comparisons difficult; separation of the nutrition facts table from the list of ingredients makes decision making tedious. Inadequate spacing between lines of print creates problems for readers of English and exacerbates problems for readers of French. Words placed over illustrations, busy backgrounds or watermarks increase reading difficulty. Hazard statements, instructions and storage information imbedded in other information without added space or appropriate heading is difficult to find and read. Canadian consumers echo consumers in 28 European countries who find label information difficult to find and to read and want clear guidelines/regulations on the placement and the typography of mandatory food label components     

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.     

Consumers’ Opinions and Use of Food Labels,Nutrition, and Health Claims: Results from Turkey

This study was conducted to reveal Turkish consumers’ (18–65 years residing 10 cities, n = 1200) opinions and use of food labels, nutrition, and health claims. The majority of both females and males (64.7%, 68.2%) seldom read food labels. Risk for not paying attention to food labels was increased 1.287-fold when the gender was male. The percentage of reading food labels increases as education and income levels of individuals increase (p < 0.05). Expiry dates of foods were the most frequent read item on labels (58.0%). Males mostly read information on label to learn the price of the food (71.0%) while females read it to learn the energy value of food (79.0%). Females had more knowledge on nutrition claims compared to males (p < 0.05). The nutrition claims, which were most frequently read by females and males, were trans fat free (23.5%, 21.0%) and low fat/fat free (23.3%, 20.5%). The claim organic was paid most attention on fruit and vegetables (52.0%). The claim “low cholesterol contributes to maintenance of cardiovascular-health” was the most common health claim read. In summary, Turkish consumer’s behaviour of reading labels and nutrition-health claims could change according to some sociodemographic factors and food products.     

Food choices in Ethiopia: does nutritional information matter?

This article reports results from a framed market experiment conducted to examine whether milk choices are responsive to changes in the nutritional characteristics of milk products. Using a random‐effect Tobit model, we analyzed experimental data collected from 160 participants in urban Ethiopia. It shows that sensory properties play a key role in the acceptance of reduced‐fat milk while the provision of nutrition information has a mixed effect on a price premium. Further, a substantial percentage of participants were found to have a strong preference for whole milk while only 19% of them prefer reduced‐fat milk with 2.8% price premium. The study unveils a heterogeneous preference for the nutritional quality of milk products. Consumers’ health problems and socio‐demographic characteristics influence their preference for the nutritional quality of milk products. The result also shows a nutrition‐taste tradeoff, yet consumers place more value on sensory experience. Contrary to earlier studies, we found that prior belief about milk quality influences how consumers value sensory experience and nutrition information.     

Common biases and heuristics in nutritional quality judgments: a qualitative exploration

The ways in which consumers make judgments about the nutritional quality of food products are a major concern for public policymakers. Given the focus on nutrition information in public health policies, the information processing paradigm has been widely used in past research. However, there is evidence that nutrition information processing is a difficult task for consumers. We examined 14 interviews from consumers of diverse social background in order to inventory the different kinds of heuristics used for making nutritional quality judgments. Narratives in which consumers elaborate about their strategies to assess nutritional quality of food products were analysed. Our findings show that: (1) consumers tend to use shortcuts to simplify nutrition information processing; (2) heuristics unrelated to nutrition information are commonly utilized; and (3) these heuristics rely on semantic, sensory and visual cues. The implications of our findings are discussed from a public policy standpoint.     

Labelling genetically modified food products: consumers’ concern in the United Kingdom

An online survey method was used to collect data regarding the concern and attitude of UK consumers towards genetically modified (GM) food labelling. Questionnaires were sent to 9000 participants of the online panel via emails, and 2568 consumers completed the online survey. The response rate was 29%. This study found that more than 75% of the consumers questioned were concerned about the labelling of food products with GM ingredients. Eight perceived risks and benefits of agro‐biotechnology were identified to be associated with consumers’ attitude towards GM food labelling. Among them, three were perceived benefits, such as reduced use of chemicals in crop production, improved nutritional content, and increased yields. The five perceived risks were health risks, environmental risks, moral considerations, image of multinational corporations as the primary beneficiaries of biotechnology, and growing control of multinational corporations over farming. While all five perceived risks from GM food played a statistically significant role in shaping the overall attitude towards GM labelling, improved nutritional content due to application of biotechnology was the only benefit that was statistically significant. Age of the respondents was the only demographic variable playing a statistically significant role in shaping the attitude of respondents towards GM food labelling. Older respondents were more likely to be concerned about the existing GM labelling practices than younger respondents.     

Consumers' Use of Nutritional Labels While Food Shopping and At Home

This study examines the impact of sociodemographic and nutrition/health related factors on consumers' use of nutritional labels while food shopping, at home, and when comparing nutrients for different brands of the same foods. The results generally suggest that unemployed individuals and those who place greater importance on nutrition while shopping and following the dietary guidelines are more likely to use nutritional labels while shopping, at home, or when comparing brands. Findings also indicate that education has a positive impact on the likelihood of using labels at home. The amount of time a consumer spends on shopping, primary source of nutritional information, special diet status, and consumer's perception of the importance of price and taste when shopping are also significant factors.     

Carbon information on vegetables: How does it affect the buying process?

Information on the climate impact of a food product has practically not been communicated in Germany, even though it could provide important acknowledgement of producers’ actions in low‐carbon production. So far, carbon labelling has predominantly been discussed without taking into account German consumers’ opinions (proven by empirical data) on this issue, even though involving the consumer in the considerations of a Carbon Label is essential for its success. Especially the question, if information on the product carbon footprint is a considerable factor within the search process of a purchase decision, was of special interest in this work. To answer these questions, we analysed consumers’ information‐seeking behaviour using an information display matrix (IDM) experiment with 232 participants. The IDM is a process tracing technique which allows to track the information search in a buying process. Our results show that basically the place of origin is the most important criterion for the purchase decision, followed by price and production method (conventional/organic). In contrast, the sustainability information (i.e., carbon footprint and water consumption) are at a low level of importance. Comparing two locally produced products with the help of a multinominal logistic regression‐model, it seems that the group of consumers preferring organic products is influenced in the purchase decision by the carbon footprint information. In summary it can be stated that although some people may be basically interested in carbon labelling of fresh food, the purchase decision would probably be hardly influenced by a carbon label on vegetables at present. The majority of people are more concerned about factors like origin and price so that Carbon Labelling would only be a viable option for a small group of consumers.     

The Effects of Nutrition Label Comparison Baselines on Consumers' Food Choices

Recent legislative changes in the European Union have mandated nutrition labeling for the majority of pre‐packaged foods. This research compared effects of several nutrition labeling formats on consumers' food choices (i.e., the nutrition table, GDA 100 g/ml, and GDA portion). We primarily focused on whether nutrition label information was standardized to a fixed or varying comparison baseline. Fixed baselines (e.g., 100 g/ml) allow consumers to make direct, relative comparisons of products, while varying baselines (e.g., portion size) often require consumers to undertake complex mathematical calculations. Findings suggest that consumers' food choices are likely to be healthier when nutrition label information is presented on a fixed baseline. Gender was found to moderate these effects such that women made healthier choices—but only when the nutrition label baseline was fixed. Thus, the type of comparison baseline is an important characteristic of nutrition labels for public policymakers, public health officials, and academic researchers to consider.     

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.     

Sodium content in foods: Brazilian consumers’ opinions,subjective knowledge and purchase intent

This study attempted to gain insights on Brazilian consumers’ subjective knowledge of sodium content in processed and homemade foods and their purchase intent for products with reduced‐sodium content. A questionnaire was distributed to 409 consumers selected by convenience quota sampling. We found that Brazilian consumers were concerned about the amount of salt (sodium chloride) in the products they consumed, regardless of educational levels, income, age, lifestyles, or health conditions. However, they still considered their consumption to be above WHO‐recommended limits and had little subjective knowledge about the term ‘sodium’. While processed products were considered the main contributors of high‐sodium intake, participants were not concerned about addition of salt at the table and salt in homemade food. The majority of respondents rarely read the sodium content on food labels; however, men and older individuals were more likely to read label information on sodium content. Products with reduced sodium were found to have market appeal, which justifies investments in research to develop these products. Therefore, in addition to the efforts to reduce sodium in the processed‐food industry, it is necessary to promote awareness about the importance of food labelling, especially sodium content, and the need to reduce salt in homemade food and additions during meals.     

Functional Foods and the Young

Factors such as raised consciousness about human health, development of the food industry, and medicine and branches of natural science studying the relation between nutrition and health have led to the popularization of foods with proven health effects. Such foods are called functional foods. Although there is growing interest in functional foods, there are several groups of consumers that are, more than others, interested in functional foods. To examine buying behavior and attitudes toward functional food of young consumers (18–30 years old) and to determine the most interested consumers, we conducted a survey using a self-administered questionnaire on a sample of 570 Croatian students. The majority of the respondents purchase functional foods, usually in supermarkets. Apart from taste, the most important functional food attribute is price/quality ratio. Respondents are buying functional foods because they believe that those foods are healthier and safer than other products. Examined market segments were based on respondents’ attitudes toward functional foods. The results of this research could be used in planning further development of the functional foods market for young consumers.     

Why Do We Read On‐Pack Nutrition Information so Differently? A Typology of Reading Heuristics Based on Food Consumption Goals

While prior research has extensively studied nutrition labeling use and consumer errors of judgment in the nutrition evaluation process, less attention has been paid to the consumer motivations that simplify the reading of on‐pack nutrition information. To address this gap, this study examines how food consumption goals affect consumer reading of this information. On the basis of a qualitative study, eight food consumption goals have been identified and classified into four types of motivations which impact reading behaviors: “Food Optimization,” “Food Regulation,” “Food Gratification,” and “Food as Mere Necessity.” From this typology, we derive eight on‐pack nutrition information reading heuristics as well as specific inference biases resulting from these simplifying reading strategies. This research also provides guidelines for policymakers so that nutritional messages given to consumers will be more targeted in order to promote better reading of on‐pack nutrition information at the point of sales.
