“…Nutritional literacy was first established in 1995 to assess awareness of nutrition labels among healthy individuals in Canada ( 14 , 33 , 34 ). Nutrition literacy is an individual’s ability to understand, evaluate, and effectively use nutritional information ( 35 , 36 ).…”

“…On the other hand, it is worth mentioning that nutritional literacy is considered one factor contributing to good practices in maintaining an adequate diet; that is, it provides the community with valuable information about the risks associated with malnutrition ( 14 ). Nutrition literacy is essential to promote health and well-being at individual and societal levels.…”

IntroductionThe willingness to consume healthy foods has highlighted the growing importance of health, even more so when it comes to food choice, and predicting the willingness to consume foods of a healthy brand represents an action that leads to the practice of conscious eating habits, but what is behind this willingness? To answer this question and based on previous studies such as the theory of planned behavior and nutritional literacy, this study aimed to build a predictive model through an empirical study to examine the influence of nutritional literacy (NL) on attitude (ATT), subjective norm (SN) and perceived behavioral control (PBC), as well as to determine the influence of the three variables of the theory of planned behavior (TPB) on the willingness to consume healthy brand foods (WCHBF) in the Peruvian market.MethodsThe research focused on the population that stated that they were consumers of the Unión brand (a brand whose value proposition is the sale of healthy foods), obtaining 482 consumers. The study was conducted under a quantitative, non-experimental, cross-sectional design approach.ResultsThe results support the existence of a positive and significant effect of NL on ATT, SN, and PBC, finding the exact behavior of SN and PBC in WCHBF; however, in the proposed model, it is observed that ATT has no impact on WCHBF.ConclusionApplying strategies that lead to a change in consumer behavior towards healthy brands is a matter of time and will. In this context, the findings indicate that nutritional literacy plays an essential role in the willingness to consume healthy foods, which sheds more light on the design of educational interventions and awareness campaigns that independently inform about nutritional benefits and empower consumers, allowing them to make informed and healthy choices.

“…Few studies measured NL in Brazil [ 28 , 29 , 30 , 31 ] using three instruments: the Nutrition Literacy Scale (NLS), the Newest Vital Sign (NVS), and the Nutrition Literacy Assessment Instrument (NLit) [ 28 , 29 , 31 ]. The first comprises 28 items and focuses on reading and comprehending nutrition concepts and recommendations (e.g., calcium is essential for bone health, recommended daily fruits and vegetables portions, and others) [ 29 ]. The NVS comprises six items focused on food label interpretation and the mathematical skills to calculate calories and nutrients on the food label, knowledge about the recommended intake of saturated fat and energy, and how to detect allergenic components in a product [ 28 ].…”

“…Understanding the currently mentioned needs and the possibility of accessing a significant number of subjects, specifically bank employees, this research aimed to (i) validate the NLit-Br for online application and (ii) investigate whether bank employees have an adequate NL level. As a result, it is expected that strategies aimed at food and nutrition education and health appropriate for the population studied will be developed [ 28 , 29 , 37 , 38 ].…”

Nutrition Literacy Level in Bank Employees: The Case of a Large Brazilian Company

Nutrition Literacy (NL) positively impacts diet quality and has the potential to promote health and prevent nutrition-related chronic diseases. Brazil is one of the countries with the highest rates of nutrition-related chronic diseases. Nevertheless, in Brazil, few studies have explored the NL levels of its population. To provide remote access to the Nutrition Literacy Assessment Instrument for Brazilians (NLit-Br) and assess Brazilian bank employees, we conducted a study to estimate the validity of the NLit-Br online and to investigate whether bank employees have an adequate NL level. In the first step, we randomly assigned 21 employees from three financial institution branches to two groups to complete NLit-Br paper and online versions. After an interval period, both groups completed the NLit-Br with an opposite delivery method (paper vs. online). We compared the validity of the digital and paper versions of the NLit-Br by the Intraclass Correlation Coefficient (ICC), and the reliability by Kuder–Richardson formula 20. Second, we evaluated 1174 bank employees using the NLit-Br online version. We found an excellent absolute agreement (ICC ≥ 0.75) between the paper and online versions. The questionnaire had good internal consistency (KR-20 = 0.64). The sample was characterized as mostly male (61.0%), married/cohabitant (73.8%), and white (69.8%), with high household income (85.2%), and graduated or postgraduate (97.4%). The mean age of the population was 42.1 (SD = 7.6) years. Subjects predominantly had possibly inadequate NL (62.3%). The online NLit-Br total score was significantly associated with gender, age, and household income (p < 0.05). Women and individuals with higher incomes had a higher degree of NL. Subjects over 50 years old had a lower degree of NL. There was no significant association between the NLit-Br score and the participants’ education. The NLit-Br online is a valid instrument to assess NL remotely. The population studied showed a high prevalence of inadequacy of the NL. Therefore, there is a need for targeted actions to improve the NL of bank employees.

Maintaining good dietary practices is a factor that allows a better quality of life; therefore, it is necessary to promote health via the fundamental tool of nutritional literacy. In this context, this study aims to evaluate nutritional literacy in Peru through the S-NutLit tool, which is composed of two dimensions. The scale, composed of 11 items, was applied to 396 Peruvian adults. According to the evaluation of the indicators, an acceptable reliability was found, as was a model fit with excellent estimation according to its indicators (CMIN/DIF 2.559; IFC 0.965; SRMR 0.043; RMSEA 0.063; and PClose 0.070). In this way, we seek to reinforce health promotion activities through a nutritional literacy diagnosis, which, due to its characteristics, can be self-administered and used by health entities and other entities in general that are interested in knowing the eating practices of an individual, which undoubtedly leads to good health.
