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.

Nutrition Literacy of Middle School Students and Its Influencing Factors: A Cross-Sectional Study in Chongqing, China.

Nutrition literacy plays an important role in children's dietary habits and nutrition. This study aimed to analyse the status of nutrition literacy and its influencing factors amongst middle school students in Chongqing, China. "Nutrition literacy scale for middle school students in Chongqing" was used in 29 districts of Chongqing in September 2020. The scores of nutrition literacy and its' three sub-domains (functional, interactive and critical nutrition literacy) were divided into low and high groups based on their median scores. Binary logistic regression was used to measure the influencing factors of nutrition literacy. A total of 18,660 middle school students were included in this study. The median of nutrition literacy of middle school students was 61.68 (IQR = 14.37). Interactive nutrition literacy had the highest score (median = 70.00, IQR = 20.00), followed by functional nutrition literacy (median = 68.69, IQR = 14.14) and critical nutrition literacy (median = 45.83, IQR = 25.00). Students who were the minority (OR = 0.71, 95% CI = 0.637-0.785), in senior high school (OR = 0.51, 95% CI = 0.477-0.548), in rural areas (OR = 0.85, 95% CI = 0.790-0.911), receiving school meal support from the government (OR = 0.63, 95% CI = 0.591-0.664), with other caregivers' parenting (OR = 0.86, 95% CI = 0.805-0.914), with parents having a low level of education and with an abnormal BMI [thin (OR = 0.91, 95% CI = 0.837-0.990), overweight (OR = 0.87, 95% CI = 0.785-0.968), and obese (OR = 0.83, 95% CI = 0.767-0.902)] presented less probability of being a high level of nutrition literacy. Our results could assist public health authorities in developing strategies of nutrition literacy promotion for references and theoretical foundations.

Applying a Multi-Dimensional Digital Food and Nutrition Literacy Model to Inform Research and Policies to Enable Adults in the U.S. Supplemental Nutrition Assistance Program to Make Healthy Purchases in the Online Food Retail Ecosystem.

The United States (U.S.) Department of Agriculture (USDA)-administered Supplemental Nutrition Assistance Program (SNAP) made substantial changes in response to the coronavirus disease 2019 (COVID-19) pandemic. These changes highlight the need to identify the digital literacy skills and capacities of SNAP adults to purchase healthy groceries online. We conducted a scoping review of four electronic databases, Google and Google Scholar to identify studies that measured food and nutrition literacy outcomes for U.S. adults. We applied a multi-dimensional digital food and nutrition literacy (MDFNL) model to assess six literacy levels and components. Of 18 studies published from 2006-2021, all measured functional and interactive literacy but no study measured communicative, critical, translational, or digital literacy. Six studies examined SNAP or SNAP-Education outcomes. Adults with higher food or nutrition literacy scores had better cognitive, behavioral, food security and health outcomes. We suggest how these findings may inform research, policies, and actions to strengthen the multi-dimensional literacy skills of SNAP participants and SNAP-eligible adults to support healthy purchases in the online food retail ecosystem.
