Price rather than nutrition information the main influencer of consumer food purchasing behaviour in South Africa: A qualitative study

In South Africa there has been a paucity of data on food and nutrition labelling since the publication of the new food‐labelling legislation. This study aimed to explore whether the nutrition information on food products influences consumer purchasing behaviour; reasons for reading or ignoring nutrition information on labels, and to investigate expectations regarding food / nutrition labelling. Nine focus‐group discussions were held with adult consumers (N=67) in Cape Town, South Africa. Food price was sometimes the only consideration when selecting food products, irrespective of quality and nutritional value. When buying products for the first time, consumers were more inclined to read the nutrition information compared to habitual purchases or buying known brands. The list of ingredients, nutrient content claims and specific health endorsement logos were considered important. Reasons for reading nutrition information were mainly to assess the nutritional value or health properties, to avoid certain ingredients/allergens and to determine quality. Consumers struggled to understand the information on labels, specifically the nutrition information table. A lack of time or interest, price concerns and trust in labelling information also emerged as reasons why consumers ignore the nutrition information. There is a need for simpler food labelling, more graphics, and less complex terminology, information overload and quantitative information. It is recommended that a standardised front‐of‐package labelling scheme and a single health endorsement logo for South Africa be considered. More should be done to educate consumers on utilising the information on food labels correctly, in order for them to make healthier food choices.     

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.     

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.     

A comparative analysis of hedonic models of nutrition information and health claims on food products: An application to soup products

Over time, the quality of data on food purchases and label information has improved such that hedonic analyses to determine the implicit prices of product attributes can be conducted using more detailed data than in the past. With the availability of more extensive data, it is important to understand the characteristics of the data and implications of using different data sources on results of analyses. The purpose of this study was twofold: (1) compare results between two sources of label information and (2) develop a better understanding of the effects of product claims and nutrition information on the value of products to consumers. Trans fat claims, organic claims, private label, package size, and several nutrients were found to influence implicit prices for soup products, and the results between the two data sources are comparable.     

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’ perception of food packaging in Trinidad,West Indies and its related impact on food choices

The purpose of the study was to investigate consumers’ perception of food packaging and its impact on food choices. The study population comprised 82 people who were ultimately consumers of packaged food products. The sample was drawn from six major supermarkets located in different geographical areas in Trinidad, West Indies. Data collection was carried out by using a questionnaire based on five topics: visual impact or attractiveness of the packaging; type of packaging material; labelling and nutritional information; new products; and fruit preserves. The packaging feature that influenced most of the respondents’ choice of products was information on the label (41.5%); it was followed by quality and type of packaging (24.4%), brand name/popularity (22.0%) and visual impact (12.2%). When asked if they would purchase a product that was most attractively packaged, 85.4% responded in the affirmative. Most respondents (92.7%) believed that packaging material could adversely affect the quality of performance of a food product. Also, 92.7% of respondents agreed that nutrition information should be shown on all food products, although 36.6% admitted that they do not read the label because of its complexity. Influence of gender was not significant (P < 0.05) on consumer perception of food packaging and on food choices. Although the sample was small, the data highlighted the need to educate consumers of packaged foods, so that informed decisions could be taken in respect to food quality, safety and nutrition.     

Consumer Intentions to Buy Front-of-Pack Nutrition Labeled Food Products: The Moderating Effects of Personality Differences

Although the current literature suggests that consumers in general have a desire to eat healthy and also like to obtain nutrition information about food products, there still exists a gap in terms of understanding how consumers utilize nutrition information. Drawing on consumer psychology literature, we examine how self-efficacy, healthy eating intentions, and perceptions about a simple front-of-pack nutrition label affect purchase intentions, and how these effects may be moderated by two information-processing-related personality traits—need for cognition and propensity to self-reference. We find that consumers’ intention to purchase front-of-pack nutrition-labeled products is positively affected by self-efficacy and label perceptions but is not directly driven by a general interest in healthy eating. We also find significant moderating effects from both personality traits considered.     

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.     

Effects on Nutrition Label Regulation on Consumer Choice

The U.S. government initiated food labeling reform in 1989, which culminated with the Nutrition Labeling and Education Act (NLEA) of 1990, emphasizing the provision of improved nutrition information on most food products. The goal of such labeling reform has been to provide consistent, readable, understandable and usable food labels that enable consumers to make more healthful food choices. This paper examines the theoretical impact of the new regulations on consumer food choice behavior. The paper first discusses the use and impact of food labels by/on consumers, and uses a choice model to desribe the effects of these new labels on consumer food choice decisions. In particular, the research focuses on two important food attributes, and the presence of information of these attributes through the new nutrition labels, which may influence consumer purchase behavior.     

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.     

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.     

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.     

The Effect of Nutrition Information on Brand Rating: Test for a Non-Use Benefit

Although consumers tend to express positive attitudes toward nutrition labeling when questioned directly, research indicates that most people do not use the information to help them make purchase decisions. While direct usage rates may be low, there may, however, be non-use benefits associated with the information. This article describes the findings from a laboratory experiment which employed an indirect and highly structured research method to study an important non-use benefit. The results indicate that consumers have more favorable attitudes toward food products which supply more information on the label.     

The Influence of Nutrition Information on Choice: The Roles of Temptation,Conflict and Self-Control

This study investigated the impact of nutrition information on consumers' choice of a cake and examined the roles of key psychological decision factors. Based on a generalized linear model, results of an experiment on 299 female consumers in the United Kingdom showed that the presence of nutrition information in the form of Guideline Daily Amount (GDA) had a direct impact on food choice. GDA information had a moderating effect on the relationship between two psychological factors (conflict and self-control, but not temptation) and consumer choice. Temptation, conflict and self-control had direct effects on choice.     

Do They Have Your Number? Understanding the Moderating Role of Format Effects and Consumer Numeracy for Quantitative Front‐of‐Package Nutrition Claims

Front‐of‐package (FOP) nutrient content claims are often used by food manufacturers to promote the nutrition levels of their products. In this research, two studies examine the influence of the numerical format (either percentages or absolute numbers) presented on FOP‐reduced nutrient content claims and the moderating influence of consumers' numeracy levels (i.e., consumers' ability to interpret numbers). Low numerate consumers are more strongly influenced by the label's numerical format, but results differ across nutrition attributes linked to cardiovascular disease risk. For saturated fat, low numerate consumers had more favorable evaluations of the product that had a label presented in a percent format compared to an absolute unit format. In contrast, the moderating effect of numeracy had little effect on the format of reduced sodium claims. Implications are offered for policymakers, consumer researchers, and food manufacturers .     

Food and nutrition education in American elementary schools: a national survey

A random sample of American elementary school educators, representing all but three of the 50 United States, responded to a questionnaire designed to ascertain: (1) their opinions concerning the inclusion of food and nutrition concepts in the elementary school curriculum; (2) their actual practices concerning the teaching of food and nutrition in the elementary classroom: and (3) their needs for elementary food and nutrition teaching materials. The results suggested that nutrition was the food and nutrition concept area most highly valued in relation to the education of young children and the concept area most frequently taught in American elementary classrooms; it also represented the concept area most in need of the development of teaching materials. Congruently, nutrition represented the food and nutrition concept area most frequently reported as being supported by American school administrators.     

Affirmative Disclosure of Nutrition Information and Consumers' Food Preferences: A Review

In order to evaluate a food advertising regulation proposed by the FTC, this paper examines some empirical studies of food marketing practices and their influence on consumer attitudes and behavior toward nutrition information and dietary habits. The requirement for affirmative disclosure of nutrition information may fall short of its intended goal because consumers have low motivation to use such information and inadequate comprehension of it. Moreover, the limited information processing capacity of the average person may preclude effective communication of nutrition information in a television commercial. The regulation's most likely impact would be to create awareness of nutrition information and increase the salience of nutrition in the consumer's food choices. Unless consumer education programs are coordinated with the regulatory efforts, lack of motivation and comprehension in the use of nutrition information will be a major barrier in achieving any significant improvement in the nutrition status of consumers.     

Food Labels’ Impact Assessment on Consumer Purchasing Behavior in Malaysia

The purpose of this study is to validate the impact of food labels among Malaysian consumers using an extended theory of planned behavior model (TPB). In doing so, the study assessed the direct and indirect effect of food labeling on consumer intention to purchase or otherwise the food products of interest. A stratified random sampling technique was adopted in selecting 2,014 consumers in Klang Valley, Malaysia. The results of structural equation modeling supported the adequacy of the proposed model. This study contributes to and extends the understanding of food labeling and purchasing behavior, identifying the rationales for purchasing of food products with labels that contains information such as halal logo, ingredients, and nutritive value.
