Objective: To determine the ability of consumers to: locate and manipulate food label information; assess the accuracy of nutrient content claims and which health/nutrient claims are allowed; and identify symbols on food labels. Associations pertaining to use and knowledge regarding food label information were also determined for consumers from different demographic and related groups.Design: An exploratory descriptive study was undertaken, employing a face-to-face survey focusing on demographic information, shopping behaviour, nutrition is important beliefs, label use, label knowledge and label preference and information sources.Setting: Selected public locations in Potchefstroom in the North West Province of South Africa.Subjects: Respondents (n 229) complying with set inclusion criteria were recruited through purposive sampling.Results: The results indicated respondents’ general health and label awareness, as most of them (>80 %) could locate label information and identify symbols and specific nutrient content claims although only 53 % were able to calculate the number of servings. Nevertheless, an inability was found to assess the accuracy of some nutrient content claims and permissible health/nutrient claims. More educated, younger, Afrikaans- and English-speaking respondents seemed to be more knowledgeable regarding food label information.Conclusions: Respondents who were informed about nutrition were also informed about label information, while label reading practices resulted in label-influenced purchasing decisions. Educational programmes on food labels should start with nutritional background that could be implemented by consumers during label reading and purchasing decisions.

Awareness and understanding of green consumer behaviour (GCB) in emerging economies can increase consumer participation in green initiatives, leading to better product and behavioural choices and protecting scarce resources. Therefore, consumers should actively change their daily habits, lifestyle, and behaviour choices. A transdisciplinary critical realism approach can complement current knowledge on green consumer behaviour theories, which can layer behaviour change as a circular feedback process. Our approach could surpass linearity and rational decision-making—embracing the power of sustainable daily habits. We reviewed green consumer behaviour theories and identified the social cognitive theory (SCT) to support our approach. Hence, we employed an integrative review of applied SCT and green consumer behaviour. Findings suggest GCB as a reciprocal process with behaviour not only the outcome but an integral part of the process, as are personal and external determinants, existing in laminated layers of meaning that transcend the obvious. Finally, we propose a novel adapted framework that considers critical constructs that warrant investigation of an emerging economy context to identify consumers’ challenges that impede behavioural change. Recommendations include segmenting consumers through pro-environmental self-identity, consumer personalities, and daily habits, which can help target consumers with appropriate messages and interventions to encourage greener lifestyles.
