The consumer perspective of labeling on foodstuffs—review

Abstract

Abstract Background The information present on food labels is essential to provide consumers with proper guidance on the quality of food products, allowing the choice of a nutritionally balanced diet. Easy-to-read systems can help hungry consumers make healthier choices at the time of purchase. The goal of this research is verifying the efficacy of different food labels on foodstuffs by the consumer choices. Methods Scientific articles were analysed from 2016 to 2020, based on Pubmed and Google Scholar. Keywords such as food label, foodstuffs, food industry and consumer were used. Results From scientific research, six articles were analysed. Thus, it is estimated the analysis of 2069 participants were recruited through a large web panel provider. Age, gender, and socioeconomic status quotas were applied to recruit a diverse sample of consumers. The participants choose the healthfulness (less healthy, moderately healthy, healthier) of the foodstuffs. The Multiple Traffic Light led to significant differences in choices between healthier and less healthy products, but not moderately healthy products. No significant differences in choices were observed by product healthfulness when the Daily Intake Guide was present. The Nutrition Facts Panel was viewed for only 7% of all packages. Conclusions On some food labels it is possible to find wrong information due to the use of ambiguous and confusing words that are easily disseminated. Effective strategies are needed to promote both food choices made by consumers and food industry formulations. Nutrition is an essential key to maintaining health, so it should be done as an incentive to improve health.
