Sub-standard nutrition is a leading risk factor for many non-communicable diseases and causes 11 million diet-related deaths annually worldwide. Arabic-speaking immigrants and refugees (ASIR) are at high risk for poor nutrition due to socio-cultural and economic-ecological factors. We reviewed the literature to explore the impact of acculturation on ASIR's dietary practices and to investigate barriers vs. facilitators to healthy eating among them. ⋯ Within North America, but not Europe, unaffordability of healthy foods and lack of genetically modified food labelling were leading barriers to eating nutritiously. Community-engaged and mixed methods research on diet, nutrition and food (in)security among ASIR is required to inform the design of effective, culturally acceptable dietary interventions. Western societies need to introduce major changes in food policy and financial support for progressive programs to ensure equitable access to nutritious, culturally appropriate food for ASIR and other similar minority groups.

Review Meta Analysis
A systematic review and meta-analysis of attentional bias toward food in individuals with overweight and obesity.
Attentional bias to food stimuli may contribute to the etiology and/or maintenance of overweight and obesity. We conducted a literature review and meta-analysis per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the effect size associated with attentional bias to palatable food in persons with overweight/obesity across the age spectrum. Included studies measured attentional bias to food stimuli using two reaction-time tasks (dot-probe, emotional Stroop), eye-tracking methodology, and/or event-related potentials. ⋯ Systematic review of preliminary event-related potentials research suggested automatic, but not maintained, attention to food images in persons with overweight/obesity. Limitations of past attentional bias research in overweight/obesity, such as poor reliability of measures and lack of consideration of moderators, such as binge eating and degree of overweight/obesity, preclude the ability to draw firm conclusions. We recommend implementation of empirically based methods for improving psychometric properties of attentional bias measures and examination of potential moderators so that the field can understand whether attentional bias to food is truly greater in overweight/obesity.

Peers and siblings are considered an important influence on children's and adolescents' food choice. However, there is a lack of studies examining how peer and sibling impact is related to children's and adolescents' eating behavior. The purpose of this study was to analyze peers' and siblings' impact on children's and adolescents' healthy eating behavior identified from a literature review, summarize the results, and discuss potential social factors that may predict these associations. ⋯ Peers' influence on children's and adolescents' healthy eating behavior is often found to be negative by the increase in consumption of energy-dense and low-nutrition value foods. However, in some cases, this influence can also be a positive one, and there is a need to find effective ways of how it could be used in encouraging healthy eating behavior of children and adolescents. Studies exploring siblings' impact on children's and adolescents' eating behavior are scarce. In addition, factors related to social interaction that may explain peers' and siblings' influence on children's and adolescents' healthy eating behavior are ambiguous. Therefore, more research in this area is needed.

The term "food literacy" describes the idea of proficiency in food related skills and knowledge. This prevalent term is broadly applied, although its core elements vary from initiative to initiative. In light of its ubiquitous use-but varying definitions-this article establishes the scope of food literacy research by identifying all articles that define 'food literacy', analysing its key conceptualizations, and reporting outcomes/measures of this concept.
