“…This finding is in line with prior research highlighting the positive influence of a person's environment on NL (59) and nutrition knowledge (60). In addition to sufficient construct validity, the S-NutLit and its subscales also displayed acceptable internal reliability and moderate to good test-retest reliability, the magnitudes of which are comparable to that of existing scales in the field (14,19,22,26). The ICC for the "expert subscale" was somewhat lower than that of the S-NutLit or the "information skills" subscale.…”

“…Only one interactive NL item ("I have the necessary skills to apply nutrition information when cooking") loaded unto the "information skills" subscale. The intricate complex relationships between functional, interactive, and critical NL have surfaced in previous research (22,53). For example, in their development and validation study, McNamara et al (22) conducted separate factor analyses for the three dimensions of NL and found several factors within those dimensions.…”

“…There are several existing scales to measure NL such as the Nutrition Literacy Scale (NLS) ( 26 ), the NLit ( 27 ), and more recently the Young Adult Nutrition Literacy Tool (YA-NLT) ( 22 ). The NLS is a 28-item instrument modelled after the Short Test of Functional Health Literacy in Adults (S-TOFHLA) ( 26 ).…”

“…Even though the instrument is comprehensive in its assessment of nutrition knowledge and numeracy skills, the NLit lacks assessment of skills related to seeking, applying, and critically appraising nutrition information ( 28 ). A more recent attempt at comprehensively measuring NL can be found in the ( 22 ). The YA-NLT is a 42-item instrument that has been validated in a population of college students aged 18–24 years.…”

“…Additionally, critical NL has an engagement dimension where people display willingness to participate in actions to remove sociopolitical barriers to healthy nutrition (e.g., campaigning for more affordable fruits and vegetables in school cafeterias) (14). Nutrition literacy has been associated with beneficial health outcomes and dietary behaviors in numerous studies among the general adult population (16)(17)(18)(19)(20) and among young adults (21)(22)(23)(24)(25).…”

BackgroundDue to their high media use, young adults are frequently exposed to contradictory or even erroneous nutrition information. To properly handle and critically assess nutrition information, young adults (both general population and patient populations) need adequate levels of nutrition literacy. Currently there is a lack of suitable instruments to measure nutrition literacy in young adults (18–25 years). Therefore the aim of this study was to develop and validate a Short Nutrition Literacy (S-NutLit) scale for use in this age group.MethodsDevelopment and validation of the S-NutLit consisted of six phases: (1) item generation based on literature, (2) expert assessments to evaluate content validity, (3) cognitive interviews with the target population to assess face validity and readability, (4) pre-test to reduce the number of items, (5) validation survey to assess dimensionality with exploratory factor analyses, internal reliability with Cronbach alpha, construct and criterion validity by examining associations with age, gender, education level, health literacy, general literacy, dietary behaviors and physical activity with correlations, ANOVAs, and t-tests, (6) two-week follow-up survey to assess test–retest reliability with intra-class correlations.ResultsStarting from an initial pool of 53 items, expert assessments and cognitive interviews led to the reformulation, removal, and construction of items. Young adults aged 18–25 years participated in cognitive interviews (n = 12), pre-test (n = 101), validation survey (n = 300), and reliability survey (n = 92). The final S-NutLit consisted of 11 items rated on a 5-point scale distributed across two subscales (i.e., information skills and expert skills). Cronbach alpha values ranged from 0.79 to 0.83 and intraclass correlations from 0.61–0.79 (p < 0.001). Significant associations were observed with health literacy (r = 0.27, p < 0.001), general literacy and numeracy (rs = 0.12, p = 0.046), and education level (rs = 0.13, p = 0.025).ConclusionFindings indicate that the S-NutLit is a valid and reliable tool to assess nutrition literacy among young adults. The S-NutLit fills a gap in the field by offering a short measure of nutrition literacy and may be incorporated in digital technology to support the nutrition care process.

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.
