Nutrition and Food Literacy in the MENA Region: A Review to Inform Nutrition Research and Policy Makers

Background: Improving food and nutrition literacy is fundamental to tackling the Middle East and North Africa (MENA) region’s enormous challenges, including malnutrition and food insecurity. To direct initiatives, it is crucial to assess the region’s food and nutrition literacy. Thus, we aimed to review studies on food/nutrition literacy status in the MENA countries and illuminate the region’s research gaps in these areas, in terms of assessment, policy, and program implementation. Methods: PubMed and Google Scholar databases were searched between 18 December and 8 May 2022, to identify relevant articles published up to 2022 in the MENA region. Results: Twelve studies were included in this review. Lebanon, Palestine, and Iran are the only three MENA countries where nutrition and/or food literacy were assessed. People in these countries mostly had inadequate food and/or nutrition literacy levels, especially in the skills rather than the cognitive domain. Food and/or nutrition literacy showed associations with food habits, food-label use, food-consumption patterns, school performance, food security, dietary diversity, and nutrient adequacy. The MENA countries developed no policies or programs to address food and nutrition literacy. Conclusion: This review is a wake-up call for researchers and policymakers to develop a robust approach to combat food and nutrition literacy concerns in the MENA region.


Malnutrition and Food Insecurity Burden in the MENA Region
The triple burden of malnutrition and anemia along with the coexistence of food insecurity are tremendous challenges in the MENA region [1]. With ongoing conflicts, political instability, and the COVID-19 pandemic, the region is witnessing an unprecedented increase in food insecurity, a decline in dietary diversity [2], the adoption of unhealthy eating patterns, and changes in food literacy [3]. In addition, the ongoing conflict in Ukraine, since February 2022, is compounding the impacts of two long years of the COVID-19 pandemic on economies, food insecurity, poverty, and malnutrition in the MENA region [4]. It is expected that the number of people affected by hunger in the region will surpass 75 million by 2030 [5]. Recent estimates show that more than 7 million children in the region suffer from chronic malnutrition, manifested as stunting [6]. Besides, 3.7 million children have Table 1. Summary of definitions of food literacy and nutrition literacy over the years.

Food and Nutrition Literacy and Nutrition Outcomes
Promoting food and nutrition literacy is a determinant factor in leading to healthy food choices and the adoption of healthy diets by children and adolescents, in particular [28]. Plenty of evidence shows that adequate levels of food and nutrition literacy are positively associated with food selection, food preparation, eating habits, and diet quality [28]. For instance, a higher level of food and nutrition literacy has been associated with increased consumption of fruits and vegetables [29], preference for healthy food [30], and decreased consumption of prepacked or processed food [31]. Besides, having limited food skills was shown to be associated with increased consumption of ultra-processed foods [32]. Above these, inadequate food literacy had exacerbated food insecurity by impeding adequate food utilization [33]. Though evidence demonstrating the relationship between nutrition outcomes and food and nutrition literacy is still developing, the foregoing findings suggest that food-and nutrition-literacy-based interventions in the MENA region are extremely promising.

Rationale of the Study and Study Objectives
As outlined above, in order to address the region's emerging challenges, it is necessary to adopt a package of intervention measures, focused on improving food and nutrition literacy and guided by a thorough analysis of the region's nutrition situation, especially in the critical stages of life, such as childhood and adolescence. In fact, inadequate nutrition in childhood and adolescence can potentially retard growth [34]. Equipping people with adequate nutrition knowledge and food skills is one promising approach to reducing MENA's malnutrition and food-insecurity burden [35][36][37]. In light of this, and in order to direct initiatives, additional information about the state of food literacy and nutrition literacy in the MENA region is needed. Therefore, in this paper, we aimed to: 1.
Review studies on the food-literacy and nutrition-literacy status in the MENA countries.

2.
Illuminate the region's current research gaps in these areas, in terms of assessment, policy, and program implementation.

Search Strategy and Data Extraction
We conducted an extensive review of the literature on studies on the assessment of food literacy and nutrition literacy in the MENA countries published up to 2022 using the online databases: PubMed and Google Scholar. We also hand-searched for the relevant literature using snowballing by accessing reference lists to identify additional papers. The following search terms were used: "food literacy"; "nutrition literacy"; "MENA region"; "MENA countries" "Lebanon"; "Egypt"; "Saudi Arabia"; "United Arab Emirates"; "Qatar"; "Morocco"; "Jordan"; "Bahrain"; "Oman"; "Tunisia"; "Kuwait"; "Palestine"; "Iraq"; "Syria"; "Libya";" Algeria"; "Iran"; "Yemen". These keywords were chosen by referring to the latest classification of the MENA countries according to the Office of the United States Trade Representative (USTR) [38], which are presently the 18 countries listed above. The keywords were used in various combinations to find relevant articles. This search was performed between 18 December and 8 May 2022. Filters and limits included (in PubMed database) the English language and the human species to avoid irrelevant searches. The reviewers screened the title and abstract of the citations to highlight the suitable articles relevant to the objective of the review for further inclusion. Eligible studies included those that assessed food literacy and/or nutrition literacy in any MENA country, used a cross-sectional design, and included healthy participants of any age. For those articles that appeared relevant, the full-text study report was obtained and data were extracted, to be documented in an Excel spreadsheet using a prepared template including the following information: study title, authors' names, year of publication, country, study objectives, sample size, age group, study instruments, and relevant findings. The detailed search strategy and identification process of included articles are shown in Figure 1.
The review findings on the status of food and/or nutrition literacy were compared with that obtained outside the MENA region to allow for comparison and discussion. Besides, we reviewed food literacy and nutrition literacy policies and programs with the countries of their implementation, to identify if any have been implemented in the MENA region.

Nutrition literacy and food label use: FNL was correlated with the use of food label. CNL and INL were correlated with looking at ingredients part of the label. Nutrition literacy and food habits: NL correlated with the use of low fat, low calorie, serving size and health benefit., lower addition of cheese and mayonnaise to food. Nutrition literacy and source of nutrition information:

17-18 years old FNLAT
The mean ± SD of the total food and nutrition literacy score was 52.1 ± 10.96 (below the minimum adequate level of 60).
Food and nutrition literacy and gender: girls had significantly higher functional score than boys, while food label score was significantly higher in boys as compared to girls. Food and nutrition literacy and school performance: high FNL score was significantly higher among students who had better school performance (OR = 1.13, CI = 1.06-1.20). Food and nutrition literacy and food label use: participants who had a family member with a nutrition-related disease had a higher score of food label reading skill (OR = 1. 48 Food and nutrition literacy and eating behaviors (meal patterns): High food and nutrition literacy scores in the cognitive domain were negatively associated to irregular breakfast intakes compared to everyday eating breakfast, irregular lunch intakes compared to everyday eating lunch and irregular dinner intakes compared to everyday eating dinner. Food and nutrition literacy and food habits: High food and nutrition literacy scores in the cognitive domain were attributed to never eating sausage/ hamburger. Food and nutrition literacy scores in the skill domain were positively associated to never eating sweet snacks.  FNLIT and sociodemographic variables: gender, parent's education and age, and birth order.

Food and/or Nutrition-Literacy Status in the MENA Countries
Taleb, S. and Itani, L. (2021) [39] assessed the nutrition literacy among 189 Lebanese adolescents aged 14-19 years old and the association of nutrition literacy with adolescents' BMI status and food habits. Lebanese adolescents had adequate nutrition literacy on the nutrition and health, macronutrients, and food-groups literacy components of the NLAI scale; however, marginal nutrition literacy was observed for household-food measures and food-label reading [39]. In contrast, Natour, N. et al. (2021) [40] reported that about one quarter (29%) of Palestinian adult participants appeared to have adequate nutrition literacy. Tell et al. (2021) [41] further found that the mean of functional nutrition literacy (FNL) was 2.8 ± 0.5 (over 7), 3.3 ± 0.5 (over 8) for interactive nutrition literacy (INL), and 3.6 ± 0.5 (over 11) for critical nutrition literacy (CNL), indicating literacy insufficiency at all sublevels among Palestinian adults.
The food and nutrition literacy has been widely addressed in Iran more than any other country in the MENA region. Ashoori, M. et al. (2021) [42] explored that Iranian senior-high-school students (17-18 years old) had inadequate levels of food and nutrition literacy, with a mean ± SD of the total food and nutrition literacy (FNL) score equal to 52.1 ± 10.96 (a score of 60 is considered acceptable) [42]. Among 803 Iranian student participants (10-12 years old), 68.8% of them had high food and nutrition scores in the cognitive domains (understanding food and nutrition information); nevertheless, at least one out of four students (25%) had low score values in the skill domain (including food label literacy, food choice literacy) [43]. Moreover, the study findings by Doustmohammadian et al. (2020) [44] reemphasized the latter, by showing that 25% of school-age Iranian students had low scores in the skill domain, and the majority (97.4%) scored moderate-tohigh in the cognitive domain of the food and nutrition literacy. Similar findings were also reported in a 2019 published paper [47], which explored that even though most Iranian adolescents had adequate food and nutrition literacy, more than half (69%) had the highest score in the cognitive domain, while only few (15%) scored highly in the skills domain. Khorramrouz, F. et al. (2020) [33] demonstrated that 14% of 315 Iranian students had inadequate food and nutrition literacy, and only 23.2% had high food-and nutritionliteracy scores. Mehri et al. (2020) [45] also reported that most Iranian adolescents had poor food and nutrition literacy (62% of males and 58.1% of females). As well, the nutrition literacy score in elementary school teachers in Yasuj, Iran was 27.14 ± 3.2, revealing that 22.7% of participants were nutritionally illiterate [48]. Added to these, the mean ± SD of total nutrition literacy was 52.98 ± 7.15, an indication of inadequacy in literacy levels among Iranian young adolescents (13-15 years old) [49]. On the contrary, about half of Iranian medical students (48.1%) showed adequate nutrition literacy, and, interestingly, only 1% had poor nutrition-literacy scores [46]. Therefore, food literacy and nutrition literacy have been inadequately addressed in the MENA countries, with the most data available in Iran. Moreover, where assessed, the data seem distressing, with critical deficits in skills rather than cognitive areas, such as food-label reading, food selection, and cooking. Nonetheless, food literacy and nutrition literacy were shown to be of better status in multiple countries outside the MENA region, even among adolescent participants. This was evident in recent studies conducted in China [74], Turkey [62][63][64], the U.S. [75], and Ghana [76], with all emphasizing adequate nutrition literacy in the sampled population, showing good competencies in most or even all food-literacy and nutrition-literacy components. Besides, good nutrition-literacy levels and basic food literacy were recorded in Greece [67] and Canada [77], respectively. The disparity between the MENA countries and other nations' findings may be attributed by the latter's investment in food and nutrition education. For instance, in the U.S., the percentage of schools providing nutrition education and instructions was 74.1% in 2014 [78]. Besides, it is encouraging to note that Nigeria has decided to increase investment in school food and nutrition [79]. Evidence suggests that people can change their behaviors to improve their nutrition outcomes, particularly when they are in supportive environments [80]. Thus, in a region such as the MENA that is plagued by numerous conflicts, the people, especially children and youth, need opportunities to develop nutrition and food literacy through food and nutrition education, standards, and policies. In addition to national governments, activists and advocates have a role to play in bringing about change. This is in line with the call for systemic change made by Agenda 2030 and the emphasis placed on food systems in the outcome documents of the Second International Conference on Nutrition (ICN2).
Most of the reviewed studies in the MENA region included adolescent participants, with all reporting dismal literacy levels in this vulnerable age group. This observation is crucial because adolescence encompasses critical stages of development and rapid growth, mainly the pubertal growth stage, during which nutrient requirements increase [79]. Accordingly, nutrition-related problems have been observed among adolescents having inadequate levels of nutrition literacy [13]. Therefore, it is essential to promote healthy eating habits during this unique life stage, by having interventions be delivered continuously, with a specific emphasis on school-based food and nutrition education. Besides, the review presently reveals that skill-based literacy, mainly food-label use, is more problematic than cognitive-based literacy, with lower use of food labels among food/nutrition-illiterate participants [40,[42][43][44]47]. Based on many pieces of evidence, food-label reading is one pivotal step to improving food choices and dietary habits [81]. One possible explanation for observing such findings in the MENA countries is that this concept and its application have neither been entered into school curricula and textbooks nor in education programs, to empower individuals in basing their food choices according to nutrition-and safetyrelated considerations. One recent study showed that Lebanese shoppers expressed poor nutrition-label-related knowledge, and more than half the population either read nutrition labels occasionally or did not look at the food label at all [82]. Emirati consumers reported looking mostly at the expiration date of the products rather than the information related to the food-storage and -handling instructions and the biotechnology as well, which are key components of being food literate [83]. Similarly, only 42% of Bahraini consumers read the food label, with the common practice being reading the basic label information related to production and expiry dates [84]. Food-literacy interventions focusing on consumer' skills to read food labels should be prioritized in such regions, where nutrition inadequacy and malnutrition are not uncommon. Thereupon, Hoteit M. and colleagues (2022) [82] provided data on this topic, "the first steps in the Nutri-Score roadmap", to serve as an initiative to motivate the national implementation of food-labeling approaches in Lebanon such as the Nutri-Score front-of-pack label.

Correlates of Food and/or Nutrition Literacy in the MENA Countries
This review found associations between food and/or nutrition literacy and critical factors and correlates. The nutrition literacy of Lebanese adolescents was associated with their food habits; nevertheless, an unusual finding is that participants with higher nutrition literacy scores had poorer food habits (higher fat intake, higher sweets intake, and lower intake of fruits and vegetables) as compared to other participants with low nutrition-literacy scores [39]. Related to this, Taleb, S. and Itani, L. debated that nutrition literacy alone, if not coupled with essential behavior capabilities and environmental support, may not guarantee behavior change [39]. What is also worth mentioning is that the body mass index (BMI) of Lebanese adolescents did not correlate with their nutrition literacy [39]. However, higher nutrition-literacy levels among Palestinian adults predicted better use of the food labels as well as checking the health benefits on the label and, in consequence, higher consumption of low-calorie products [40]. In addition, the food and nutrition literacy were correlated with the use of food labels and looking, in particular, over the ingredients part of the label [41]. Adding cheese and mayonnaise to meals was less common in participants with adequate critical food and nutrition literacy [41]. Participants with better FNL seemed to rely on health professionals and scientific books rather than unreliable online sources to seek nutrition information [41].
Ashoori, M. et al. [42] found that high food and nutrition literacy scores predicted better school performance among high school students. Participants who had a family member having a nutrition-related disease scored higher on the food-label-reading skill of the food and nutrition literacy [42]. Better food and nutrition literacy anticipated everyday intake of breakfast, lunch, and dinner compared to those who used to skip meals [43]. Participants having higher food-and nutrition-literacy scores reported lower consumption of sausages, hamburgers, and sweets [43]. Further, food and nutrition literacy were a barrier to dietary diversity and nutrient adequacy in school-age children in Iran [43]. A low level of functional food and nutrition literacy (FFNL) was significantly associated with a lower intake of fruits and meat products [43]. Likewise, inadequate food-label literacy predicted significantly lower consumption of dairy and meat products [43]. It was also found that poor food and nutrition literacy was significantly associated with a low level of nutrition adequacy ratio (NAR) of protein, calcium, vitamin B3, vitamin B6, and vitamin B9 and the probability of a lower-level mean adequacy ratio (MAR) [44]. Adolescents who were in contact with healthcare providers had better food-and nutritionliteracy scores [45]. Moreover, an increase in total nutrition literacy (T-NL), INL, and CNL enhance diet quality [49]. An increase in FNL was associated with lower sugar intake and better energy balance in male participants [49]. Further, higher education level was also a significant correlate with the nutrition literacy [48]. Nutritional literacy had a significant correlation with the field of study, residence, and body mass index (p < 0.05) [46]. Food and nutrition literacy and food insecurity have also been associated, and food-insecure participants were about three times more likely to have low food and nutrition literacy scores compared to the food-secure participants (OR = 2.86, 95% CI 1.35, 6.05; p = 0.006) [33].
The review findings of food literacy and nutrition literacy correlate with those reported by studies outside the MENA boundaries, with significant associations with a myriad of nutrition outcomes. Costarelli, V. et al. (2021) [67] debated that better parental nutrition literacy was significantly associated with the feeding practices of their children, including healthy-eating guidance and monitoring practices. Moreover, better food literacy was found to have a negative association with fast food consumption and alcohol abuse among secondary students (16-21 years old) in Portugal [68]. The relationship between food literacy and food security has been also addressed in Australia, showing that food-insecure participants were 1.4 times less likely to base their food choices on looking over the nutrition information panel [85]. Furthermore, food-label use was higher among Turkish adolescents having adequate nutrition literacy, who also experienced lower consumption of fast food and reliance on reliable sources to search for and access nutrition information [64], which were also emphasized by the findings reported by Ayer, Ç. and Ergin, A. (2021) [62] and Koca, B. and Arkan, G. (2020) [63]. Besides, there was a significant positive relationship between food literacy and students' dietary behavior in Ghana [76]. Moreover, multiple studies reported a positive association between food literacy and adolescents' dietary intake; adolescents with greater food knowledge and frequent food preparation behaviors had healthier dietary practices [13]. Taken together, improving communities' food and nutrition literacy could refigure the nutrition situation in many countries, pushing them closer to or even attaining Goal 2 of the 2030 Agenda of Sustainable Development, which is to end all forms of malnutrition.

Existing Food Literacy and Nutrition Literacy Policies and Programs
The published literature reveals that the MENA countries have not adopted any foodliteracy or nutrition-literacy policies and programs yet, despite the need and the evident effectiveness of the existing ones. On the other hand, many countries have taken the initiative to formulate and adopt school-based programs and policies to promote food and nutrition knowledge and skills among children, and in certain circumstances, those of their parents and other community members. According to Hawkes and colleagues [80], there are four mechanisms by which a policy can influence food preferences and support healthy-eating patterns: (1) policy provides an enabling environment for healthy-preference learning; (2) policy overcomes barriers to the expression of healthy preferences; (3) policy encourages people to reassess existing unhealthy preferences; and (4) policy stimulates a food-system response. Table 3 lists a collection of food-literacy and nutrition-literacy programs and policies, along with the countries in which they were implemented, the target group, a brief description of the program/policy, the theory they are based on, the effectiveness, and the evaluation tools. Countries such as Australia and the United States appear to have made the most efforts in developing effective programs to improve the food literacy and nutrition knowledge of intervened participants. Refer to Table 3 for more details about the existing policies and programs.

Limitations and Strengths of This Review
This review has some limitations. There is the potential for missing studies because only a few databases were searched. Nonetheless, the strength of this review is crystallized, contributing to the literature by highlighting the MENA's undervaluation of the foodliteracy and nutrition-literacy concepts in terms of original definitions, assessment, policies, and programs. Our findings can be used to inform researchers and policymakers to start taking incremental steps to improve the state of food literacy and nutrition literacy in the region. Primary outcomes: children's self-reported fruits and vegetables intakes (serves/day).
Secondary outcomes: Food literacy constructs such as: nutrition knowledge, food preparation and cooking skills, self-efficacy and behaviors, food waste knowledge and behaviors and food production knowledge.
A 25-item online survey was developed for administration at baseline (impact evaluation) and immediately post-intervention (impact and process evaluation).

Conclusions
Food and nutrition literacy is one of many factors contributing to the prevalence rates of malnutrition and health outcomes. This review emphasized that there is a current dearth of data, policies, and programs regarding food literacy and nutrition literacy in the MENA region. The authors present this review data to spur additional research efforts into these topics in such a region plagued by high rates of malnutrition and nutrition-related disorders. This review is a wake-up call for researchers and policymakers to develop a robust approach to address and combat food literacy and nutrition literacy concerns in the MENA region.

Recommendations and Future Perspectives
The MENA countries should start taking steps to create a supportive environment that boosts the food literacy and nutrition literacy of people in the region. Nutrition education and food and nutrition programs and policies are indispensable to providing an enabling environment for healthy dietary behaviors and stimulating a food system response. The existing policies need to be evaluated and monitored formally to assess the extent of implementation and whether they are applicable in the MENA region, having the same promising short-term and long-term effective outcomes. Nutrition and food education in child care and school settings is one of many steps that can be initiated to pave the way to come near to achieving the sustainable development goals (SDGs) by 2030. Regional researchers should prioritize conducting sufficient studies on food and nutrition literacy as well, to serve as baseline data for stakeholders and policymakers for taking an action. It is the researchers' responsibility to point out when and where to act, as it is the vulnerable population that benefits the most from intervention, and the best ways to develop, monitor, and evaluate food-literacy and nutrition-literacy programs.
