Birds exposed to food insecurity—defined as temporally variable access to food—respond adaptively by storing more energy. To do this, they may reduce energy allocation to other functions such as somatic maintenance and repair. To investigate this trade-off, we exposed juvenile European starlings ( Sturnus vulgaris , n = 69) to 19 weeks of either uninterrupted food availability or a regime where food was unpredictably unavailable for a 5-h period on 5 days each week. Our measures of energy storage were mass and fat scores. Our measures of somatic maintenance were the growth rate of a plucked feather, and erythrocyte telomere length (TL), measured by analysis of the terminal restriction fragment. The insecure birds were heavier than the controls, by an amount that varied over time. They also had higher fat scores. We found no evidence that they consumed more food overall, though our food consumption data were incomplete. Plucked feathers regrew more slowly in the insecure birds. TL was reduced in the insecure birds, specifically, in the longer percentiles of the within-individual TL distribution. We conclude that increased energy storage in response to food insecurity is achieved at the expense of investment in somatic maintenance and repair.

Results of the food consumption surveys are utilized in many areas, such as for example risk assessment, cognition of consumer trends, health education and planning of prevention projects. Standardization of national consumption data for international comparison is an important task. The intention work began in the 1970s. Because of the widespread utilization of food consumption data, many international projects have been done with the aim of their harmonization. The present study shows data collection methods for groups of the food consumption data, their utilization, furthermore, the stations of the international harmonization works in details. The authors underline that for the application of the food consumption data on the international level, it is crucial to harmonize the surveys’ parameters (e.g. time of data collection, method, number of participants, number of the analysed days and the age groups). For this purpose the efforts of the EU menu project, started in 2012, are promising. Orv. Hetil., 2012, 153, 1692–1700.

Abstract Introduction Understanding the various eating habits of different population groups, according to the geographical area, is critical to develop evidence-based policies for nutrition and food safety. The FAO/WHO Global Individual Food consumption data Tool (FAO/WHO GIFT) is a novel open-access online platform, hosted by FAO and supported by WHO, providing access to harmonized individual quantitative food consumption (IQFC) data, especially in low- and middle-income countries (LMICs). Methods FAO/WHO GIFT disseminates IQFC data as ready-to-use food-based indicators in the form of infographics, and as microdata. The infographics intend to facilitate the use of these data by policy makers, providing an overview of key data according to population segments and food groups. The microdata is publicly available for download, and is intended for users that would like to do further analysis of the data. Results FAO/WHO GIFT is a growing repository. By June 2020, 14 datasets were available for dissemination and download, and an additional 44 datasets will be made available by 2022. FAO/WHO GIFT also provides an inventory of existing IQFC data worldwide, which currently contains detailed information on 268 surveys conducted in 105 countries. Conclusions FAO/WHO GIFT collates, harmonizes and disseminates IQFC data collected in different countries. This harmonization is aimed at enhancing the consistency and reliability of nutrient intake and dietary exposure assessments globally. FAO/WHO GIFT is developed in synergy with other global initiatives aimed at increasing the quality, availability and use of IQFC data in LMICs to enable evidence-based policy-making for better nutrition and food safety.

Abstract The FAO/WHO Global Individual Food consumption data Tool (FAO/WHO GIFT) is a novel open-access online platform hosted by FAO and supported by WHO. FAO/WHO GIFT is aimed at increasing the quality, availability and use of individual quantitative food consumption (IQFC) data in low- and middle-income countries (LMIC) to enable evidence-based decision-making and policy development for better nutrition and food safety. The platform is developed in synergy with other global initiatives working with food consumption data (e.g. Intake, Global Dietary Database, FAO/WHO FOSCOLLAB). The main objective of the session is to give the opportunity to participants to apply the knowledge gained over the previous sessions. Participants will be divided in small groups to do hands-on exercises using the features of the platform. Participants will learn how to identify existing IQFC surveys worldwide using the FAO/WHO GIFT inventory map. Participants will also explore the potential of the Indicators section of the platform according to the needs of different fields of work (food consumption, food safety and nutrition). Expert users will learn how to download dietary microdata and how to take advantage of other data sources using the same food classification and description system - FoodEx2. The workshop will close with a brainstorm session on how the FAO/WHO GIFT platform can be improved to support participants work.

Aim: to describe physical activity and ultra-processed foods consumption, their changes and sociodemographic predictors among adolescents from countries in Europe (Italy and Spain) and Latin America (Brazil, Chile, and Colombia) during the SARS-CoV-2-pandemic period. Methods: Cross-sectional study via web survey. International Physical Activity Questionnaire (IPAQ) and weekly ultra-processed food consumption data were used. To compare the frequencies of physical activity status with sociodemographic variables, a multinomial logistic and a multiple logistic regression for habitual ultra-processed foods was performed. In final models, p < 0.05 was considered significant. Results: Sample of 726 adolescents, mostly females (59.6%) aged 16–19 years old (54.3%). Adolescents from Latin America presented odds ratio (OR) 2.98 (CI 95% 1.80–4.94) of being inactive and those whose mothers had higher level of education were less active during lockdown [OR 0.40 (CI 95% 0.20–0.84)]. The habitual ultra-processed consumption was also high during this period in all countries, and more prevalent in Latin America. Conclusion: A higher prevalence of inactivity was observed in this population, but reductions of physical activity and habitual ultra-processed consumption during the pandemic were more pronounced in Latin America. Our findings reinforce the importance of promoting a healthy lifestyle, i.e., exercise and diet, during periods of social isolation.

The effects of conflict on public health and ecosystem well-being are understudied and rarely figure in public debates about war-making. Protracted conflicts are particularly damaging to people and environments in ways that are inadequately documented. In recent wars in the Middle East and North Africa, parties to the conflicts have induced hunger and displacement and undermined public health through the use of violence and economic policies that deprive civilians of access to food, water, fuel, and livelihoods. Environmental pollution is widespread, particularly in cities that became war zones, while the COVID-19 pandemic has deepened conflict-induced poverty and food insecurity.

Household food insecurity (HFI) exists when access to food is inadequate or insecure due to financial constraints, and is an issue of increasing concern among postsecondary students who face barriers to food access due to precarious finances. The goal of the current study was to explore the experience of HFI among university students in Nova Scotia (NS), including barriers and facilitators, and potential policy solutions to the issue from the perspective of students. Twelve semi-structured, in-depth interviews were conducted with students experiencing HFI from across NS. Phenomenological analysis was undertaken, using Radimer’s model of HFI as a theoretical framework. Key aspects of the experience of food insecurity in this sample included all four dimensions of Radimer’s model of HFI: quantitative, qualitative, psychological, and social. The main contributing factor to student’s difficulties accessing food was inadequate and precarious finances. Students highlighted various coping mechanisms, such as utilizing food banks, budgeting their money, and buying food in bulk. This study is an important next step to a better understanding of the experience of student HFI in NS, building on previous quantitative research. Findings suggest that while the experience of HFI has many similarities with the experience in other populations, students experience tensions between independence and reliance on their family and have unique struggles related to government financial supports. The findings point to necessary policy changes related to student funding programs, and suggest that relying on campus food banks to solve the issue of HFI among students is inadequate.
