RESUMEN

La Canasta Alimentaria Normativa (CAN) es un instrumento estratégico de planificación y seguimiento, que impacta el ámbito económico (fijación del salario mínimo SM y del umbral de la pobreza relativa), la seguridad alimentaria y la salud pública. El objetivo fue describir la evolución histórica de la CAN en Venezuela, contrastando su valoración económica respecto al SM durante el período 1990 ­ 2023. Tipo de estudio: Descriptivo. Se empleó la CAN del Instituto Nacional de Estadísticas/Instituto Nacional de Nutrición (INE/INN) y su comparación con la canasta del Centro de Documentación y Análisis Social de la Federación Venezolana de Maestros(CENDAS ­ FVM). Los valores mensuales de la CAN y del SM se recalcularon a dólares USA, de acuerdo a la tasa de cambio oficial. No se incluyó evaluación de la estructura interna, ni sus expresiones en términos de aporte de energía y nutrientes. Resultados: Desde 1990 hasta el año 2015, se requirieron entre1,0 y 1,8 SM y entre 0,6 y 1,7 Ingresos Mínimos Legales (IML)para acceder a la CAN. Para el año 2023 se requirieron hasta 78,3SM y 51,6 IML. El valor promedio de la canasta del CENDAS-FVM fue superior al valor de la CAN INE/INN, en una proporción de 1,7: 1. Conclusiones: la CAN resultó sensible en identificar los cambios y tendencias de su estimación económica, en el ambiente inflacionario venezolano. El uso de sus resultados está sujeta a cierto grado de discrecionalidad política. El costo de la CAN, expresa una contracción del poder de compra de los hogares venezolanos con potenciales impactos sobre la nutrición y la salud física y mental a corto y largo plazo.


The Normative Food Basket (NFB) represents astrategic planning and monitoring instrument, which impactsthe economic sphere (setting of the minimum wage (MW) andthe relative poverty threshold), food security and public health.The objective was to describe the historical evolution of the NFB in Venezuela, contrasting its economic valuation with respect to the MW during the period 1990 ­ 2023. Type of study: Descriptive. The NFB of the National Institute of Statistics/National Institute of Nutrition (NIS/NIN) was used and itscomparison with the basket of the Center for Documentationand Social Analysis of the Venezuelan Federation of Teachers (CENDAS ­ FVM). The monthly values of the NFB and theMW were recalculated into dollars (US$), according to theofficial exchange rate. No evaluation of the internal structurewas included, nor its expressions in terms of energy and nutrientcontribution. Results: From 1990 to 2015, between 1.0 and1.8 MW and between 0.6 and 1.7 Minimum Legal Income(MLI) were required to access the NFB. By 2023, up to 78.3MW and 51.6 MLI were required. The average value of the CENDAS-FVM basket was higher than the value of the NFBNIS/NIN, in a proportion of 1.7: 1. Conclusions: As a statistical operation, the NFB was sensitive in identifying changes andtrends in its estimate economic, in the Venezuelan inflationaryenvironment. The use of its results is subject to a certain degree ofpolitical discretion. The cost of CAN expresses a contraction inthe purchasing power of Venezuelan households with potentialimpacts on nutrition and physical/mental health in the shortand long term.

RESUMEN

Since it is an important human need and many organizations are involved in the value chain, the agricultural food supply chain is exposed to various risks that arise naturally or through human actions. This study aims to develop the application of a quality function deployment approach to increase the resilience of the food supply chain by understanding customer needs and logistical risks in the food supply chain. In-depth studies with empirical analysis were conducted to determine the importance of customer needs, food supply chain risks, and actions to improve supply chain resilience of SMEs in the agri-food industry. The result shows that the top three customer needs are "attractive, bright color", "firm texture" and "fresh smell". The top three risks in the agri-food supply chain are "improper storage," "Harvest Failure" and "Human Resource Risks" and the top three resilience actions are "continuous training," "preventive maintenance," and "supply chain forecasting." The implications of this study are to propose an idea that broadens the perspective of supply chain resilience in the agri-food industry by incorporating the needs of customers in considering how to mitigate the existing risks to the satisfaction of customers, and it also highlights the relatively low skill and coordination of the workforce in agri-food supply chains.

RESUMEN

A Segurança Alimentar e Nutricional (SAN) consiste na realização do direito de todos ao acesso regular e permanente a alimentos de qualidade, em quantidade suficiente, sem comprometer o acesso a outras necessidades essenciais, tendo como base: práticas alimentares promotoras da saúde que respeitem a diversidade cultural e que sejam ambiental, cultural, econômica e socialmente sustentáveis. A Política Nacional de Alimentação e Nutrição (Pnan), em sua nona diretriz ¿ Cooperação e articulação para a Segurança Alimentar e Nutricional ¿ versa sobre a importância de integrar as dimensões alimentar e nutricional do conceito de SAN durante a construção de políticas públicas que objetivam a garantia do Direito Humano à Alimentação Adequada (DHAA), da SAN e da promoção de saúde da população. Considerando a complexidade dos determinantes da SAN, a garantia desses direitos deve pautar-se na articulação intersetorial, integrando a Pnan às Políticas de Segurança Alimentar, de desenvolvimento econômico e social, de educação, de agricultura, além de incluir ações de diagnóstico, vigilância alimentar e nutricional e de promoção da alimentação adequada e saudável. O agravamento da situação de insegurança alimentar (IA) no Brasil desafia gestores, profissionais e toda a sociedade civil a pensar ações capazes de garantir a SAN e o DHAA. Este documento apresenta orientações para apoiar gestores e profissionais a organizar a atenção às pessoas em situação de IA, fortalecendo a articulação entre o SUS e outros setores que se relacionam com a garantia da SAN.

RESUMEN

An understanding of the types of shocks that disrupt and negatively impact urban household food security is of critical importance to develop relevant and targeted food security emergency preparedness policies and responses, a fact magnified by the current COVID-19 pandemic. This gap is addressed by the current study which draws from the Hungry Cities Partnership (HCP) city-wide household food insecurity survey of Nairobi city in Kenya. It uses both descriptive statistics and multilevel modelling using General Linear Mixed Models (GLMM) to examine the relationship between household food security and 16 different shocks experienced in the six months prior to the administration of the survey. The findings showed that only 29% of surveyed households were completely food secure. Of those experiencing some level of food insecurity, more experienced economic (55%) than sociopolitical (16%) and biophysical (10%) shocks. Economic shocks such as food price increases, loss of employment, and reduced income were all associated with increased food insecurity. Coupled with the lack of functioning social safety nets in Nairobi, households experiencing shocks and emergencies experience serious food insecurity and related health effects. In this context, the COVID-19 pandemic is likely to have a major negative economic impact on many vulnerable urban households. As such, there is need for new policies on urban food emergencies with a clear emergency preparedness plan for responding to major economic and other shocks that target the most vulnerable.

RESUMEN

BACKGROUND: The dual burden of poor diet quality and food insecurity makes free food-food acquired at no cost-a very important part of the nutrition safety net for low-income families. The goal of this study was to determine the national prevalence and nutritional quality of free food acquired separately in two settings: 1) by children at school; and 2) by employees at work; both stratified by participation in the Supplemental Nutrition Assistance Program (SNAP). METHODS: Using National Household Food Acquisition and Purchase Survey data (2012; n = 4,826 U.S. households containing 5,382 employed adults and 3,338 school-aged children), we used survey-weighted proportions to describe free food acquisition and linear regression to compare the 2010 Healthy Eating Index (HEI-2010) for free/non-free food acquisition events (i.e., meals) by SNAP status. Analyses were conducted in 2019-2020. RESULTS: SNAP households had more free acquisition events (29.6%) compared to non-SNAP households (<185% federal poverty level (FPL) = 22.3%; ≥185%FPL = 21.0%, p's<0.001). For SNAP-participant children, free acquisition events at school had a higher mean HEI-2010 compared to non-free acquisition events at school (50.3 vs. 43.8, p = 0.033) and free acquisition events by SNAP-non-participant children ≥185%FPL at school (50.3 vs. 38.0, p = 0.001). Free and non-free acquisition events at work had relatively low HEI-2010s, with no differences by SNAP status. CONCLUSIONS: Over one fifth of all food acquisition events were free, but free food acquisitions at school and work were relatively unhealthy. For children participating in SNAP, free food acquired at school had higher nutritional quality. Improving the dietary quality of free foods could improve the health of families, especially those participating in SNAP.

RESUMEN

BACKGROUND AND AIMS: An attempt to recommend scale up of dietary diversity data at household and individual level for improving the food and nutrition security, the study was conducted with the objective to explore the dietary diversity (DD) and its associated risk factors among reproductive age women in India. METHODOLOGY: A total of 5,48,806 women aged 15-49 years were asked how often they consume various types of food groups (daily, weekly, occasionally, or never). Association between adequate DD and its covariates such as individual and household were measured by using logistic regression. RESULTS: Most of the population consumed dark green leafy vegetables, milk/curd and pulses/beans. Only 1.7% of women consumed diet with adequate diversity or five or more food groups. Women's educations, gestation status, wealth status, sex of household head, household size, religion, place of residence and land ownership were significantly associated with adequate DD. The percentages of population with adequate DD varies from 7% to <1% in different states of India which shows that good-quality-diet is a major issue in entire country. CONCLUSION: There is an urgent need of programs focused on availability of food with maximum diversity at minimum cost in order to reduce maternal and child mortality in India. To reduce geographic variation in achieving adequate DD, new approaches are required in developing multiple interventions to address major preventable causes of DD. Individual state government should also take serious measure to improve the consumption of variety of food groups.

RESUMEN

The desire for fresh, local food has increased interest in alternative food production approaches, such as private small-scale agriculture, wherein households grow their own food. Accordingly, it is worth investigating private agricultural production, especially in urban areas, given that an increasing share of the world's population is living in cities. This study analyzed the growth of produce at people's homes and in community gardens, focusing on behavioral and socio-demographic factors. Data were collected through an online survey in Detroit, Michigan; 420 citizens were interviewed. The results revealed that trust, attitude, and knowledge affect the growing of produce at home. Involvement and personality are also drivers of community gardening. Regarding socio-demographics, household size affects the growing of produce at home, while gender, age, and income affect community gardening. The findings have valuable implications for stakeholders who wish to foster private small-scale urban agriculture, for example, through city planning and nutrition education.

RESUMEN

Coronavirus disease 2019 (COVID-19) can have far-reaching consequences for developing countries through the combined effects of infection and mortality, and the mitigation measures that can impact food systems and diets. Using a mobile platform, this cross-sectional study evaluated the effect of COVID-19 on food prices and dietary quality for 1797 households in Nouna and Ouagadougou in Burkina Faso, Addis Ababa and Kersa in Ethiopia, and Lagos and Ibadan in Nigeria. We assessed the consumption of 20 food groups during the previous 7 days. The dietary diversity scores (DDS) and Prime Diet Quality Scores (PDQS) were used to assess dietary diversity and quality. We used generalized estimating equation (GEE) linear models to evaluate associations between price changes for staples, pulses, vegetables, fruits, and animal source foods (ASFs) with the DDS and PDQS PDQS. Most participants reported increasing prices of staples, pulses, fruits, vegetables and ASF, and ≥ 40% reported the decreased consumption of staples, legumes, and other vegetables and fruits. The DDS (except in Kersa and Ouagadougou) and PDQS were lower during the COVID-19 pandemic. Higher pulse prices were associated with lower DDS (estimate, -0.35; 95% confidence interval [CI], -0.74 to 0.03; P = 0.07) in the combined analysis and in Burkina Faso (estimate, -0.47; 95% CI, -0.82 to -0.11). Higher vegetable prices were positively associated with the DDS (estimate, 0.22; 95% CI, 0.08 to 0.37). Lower crop production (estimate, -0.54; 95% CI, -0.80 to -0.27) was associated with lower DDS. The price increases and worsening dietary diversity and quality call for social protection and other strategies to increase the availability and affordability of nutrient-rich foods during the COVID-19 pandemic and public health emergencies.

RESUMEN

Food loss and food waste occur along the food supply chain, negatively impacting the environment, global economy, and food security. There is a growing global interest in tackling this issue to mitigate or handle the waste generated and limit its repercussions, as one in eight people suffer from undernourishment worldwide. In the Arab world, where there is a high dependency on imports and limited potential of increasing local food production, addressing food loss and waste becomes substantial. Research has mainly been focused on household food waste generation, while data on post-consumer plate food waste in the foodservice sector remains scarce. In this study, managers from a representative sample of 222 restaurants located in Municipal Beirut, Lebanon, were surveyed about food waste generation. Plate food waste was measured to establish baseline information. Multiple Tobit regression analyses were performed to explore the determinants for plate food waste generation. Plate waste generation was also compared between Lebanese and non-Lebanese cuisine restaurants. Results revealed that 1,620 tons of plate food waste are generated per year in Beirut, equivalent to 0.15% of Lebanon's total organic waste. Furthermore, Lebanese cuisine restaurants serving Mediterranean Mezze were found to generate 34 kg of organic waste per day more than restaurants that serve international non-Lebanese cuisine. The type of cuisine, kind of service, and menu planning were significantly associated with post-consumer food waste generation. This study revealed an increasing concern towards the amount of plate waste generated in Beirut, and thereby further research is needed to create baseline information at the national level.

RESUMEN

This paper analyzes the option coordination problem of a fresh agricultural product supply chain under two supply chain structures, when the production cost and the loss rate are disrupted simultaneously. This paper provides the explicit option coordination conditions for the disrupted supply chain under two supply chain structures, and then explores the effects of the disruptions and supply chain structure on the option coordination conditions. The results suggest that it is unfavorable to apply the original coordinating contracts without disruptions to coordinate the disrupted supply chain. The coordination of the disrupted supply chain can be achieved with knowledge of the distribution of demand. In two coordinating contracts for the disrupted supply chain, the exercise price is still at the original level without disruptions while the option price deviates from the original level without disruptions. Moreover, the relationships of the coordination conditions in two supply chain structures depend on the value of the profit allocation coefficient. When the profit allocation coefficient exceeds (falls behind) a certain threshold, the option price is set at a higher (lower) value in the supplier-led supply chain structure than in the distributor-led supply chain structure, while the exercise price is set at a lower (higher) value in the supplier-led supply chain structure than in the distributor-led supply chain structure. Finally, the disrupted supply chain with any supply chain structure will perform better in the modified coordinating contracts than in the original coordinating contracts without disruptions.

RESUMEN

INTRODUCTION: Effective communication approaches are necessary to reach food-security program participants. Accessing food-security programs has been especially challenging during the COVID-19 pandemic. Social media can play an important role in reducing some communication barriers. We examined interest in receiving nutrition information via social media among adults participating in food-security programs in Washington, DC. METHODS: We developed and administered a 22-item survey to adults participating in food-security programs (N = 375). Participants were recruited at Martha's Table, in Washington, DC, from January through March 2020. We performed bivariate analyses and multinomial logistic regressions to examine predictors of interest in receiving nutrition information via social media. RESULTS: Sixty-nine percent of participants reported using social media, and 49% expressed interest in receiving nutrition information via social media. Higher levels of self-efficacy and belief in the value of digital technology were associated with greater likelihood of interest in receiving nutrition information via social media (χ2 6 = 139.0; Nagelkerke R2 = 0.35; P < .001). We found no differences by sex or digital technology access in interest in receiving nutrition information via social media. CONCLUSION: Social media is a widely used and a feasible method to reach food-security program participants. Understanding program participants' interest in receiving health information via social media may help food-security programs plan effective communication strategies to improve food security, especially when in-person participation is limited, such as during the COVID-19 pandemic.

RESUMEN

The Supplemental Nutrition Assistance Program (SNAP) is critical to alleviating food insecurity, but low diet quality among program participants is a concern. Nutrition-related interventions have focused on SNAP-authorized food retailers, but the perspectives of small food store owners and managers have not been represented in national policy discussions. This study aimed to explore the opinions of store owners/managers of SNAP-authorized small food stores about their overall perceptions of the program and the stricter stocking standards previously proposed in 2016. We conducted in-depth, semi-structured interviews with 33 small food store owners and managers in San Francisco and Oakland, California in 2016. Interviews were analyzed for thematic content using the general inductive approach. Four themes emerged from owners/managers' discussion of their overall perceptions of SNAP: the beneficial impact of SNAP on their business, how SNAP enables them to connect with the broader community, the importance of SNAP in preventing hunger, and the nutrition-related struggles that SNAP participants face. Store owners/managers had a generally favorable response towards the proposed stricter stocking standards. Additional themes discussed pertained to the concern about whether stocking changes would lead SNAP participants to purchase more healthful food and some logistical challenges related to sourcing and storing perishable foods.

RESUMEN

Nutrient profiling systems, initially designed to promote healthy food choices at the point of sale, can also provide the scientific basis for innovation and product reformulation by the food industry. This work presents a new profiling system to help define feasible nutrient targets for reformulation of packaged foods. The focus is on five key nutrients for which the World Health Organisation (WHO) has set population-level goals: sugar, saturated fat, sodium, fiber, and protein. The methodology uses Mintel's Global New Products Database of packaged foods to (1) identify nutrients relevant to each food category (2) sort products into sub-categories defined by a unique nutritional signature, and (3) develop standards for "best of class" products. For instance, if targeted to be amongst the best 15% of the global food supply, pizza must have less than 4.0 g/100 g saturated fat, less than 520 mg/100 g total sodium and more than 9.8 g/100 g protein. Fiber and sugar are not identified as relevant nutrients for the pizza category and no targets are provided.

RESUMEN

BACKGROUND/OBJECTIVES: Food insecurity has emerged as a critical health issue for older adults. Food insecurity has been shown to disrupt healthy eating patterns, but these associations have not been widely studied among older adults. The objectives of the present study were to: (1) examine national trends in food insecurity across a 10-year period, and (2) evaluate the associations between food insecurity and multiple diet quality indices in a recent and nationally representative sample of adults aged 60 or older. DESIGN: Cross-sectional analysis of the 2007-2016 National Health and Nutrition Examination Surveys. SETTING: Nationally representative sample of the United States. PARTICIPANTS: The analytic sample was comprised of 5,097 adults aged 60 or older, with household incomes at or below 300% of the federal poverty level. MEASUREMENTS: Household food security was measured using the 18-item US Household Food Security Survey Module. Diet was assessed using two 24-hour dietary recalls. Multivariate linear and logistic regression models examined the associations between household food security and three evidence-based diet quality indices, adjusting for sociodemographic and health characteristics. RESULTS: Across the 10-year period, food insecurity increased significantly from 5.5% to 12.4% among older adults; this increase was more pronounced among lower-income older adults. From the linear regression models, food insecurity was associated with lower scores on the Healthy Eating Index (ß = -1.90, 95% confidence interval (CI) = -3.70, -0.09), the Alternate Healthy Eating Index-2010 (ß = -1.47, 95% CI = -2.51, -0.44), and the Mediterranean Diet Score (ß = -0.54, 95% CI = -1.06, -0.01) after multivariate adjustment. Further adjustment for the presence of chronic medical conditions did not attenuate these results. CONCLUSION: Food insecurity is associated with lower overall diet quality among older adults, supporting the need for clinical efforts to identify those at risk of food insecurity and public health efforts to alleviate food insecurity and promote healthy eating behaviors among older adults.

RESUMEN

Food additive intakes have increased with the increase in "ultra-processed" food consumption. Food additive emulsifiers have received particular research attention in recent years due to preliminary evidence of adverse gastrointestinal and metabolic health effects. In this review, the use of emulsifiers as food additives is discussed, and the current estimations of exposure to, and safety of, emulsifiers are critically assessed. Food additive emulsifier research is complicated by heterogeneity in additives considered to be emulsifiers and labelling of them on foods globally. Major limitations exist in estimating food additive emulsifier exposure, relating predominantly to a lack of available food occurrence and concentration data. Development of brand-specific food additive emulsifier databases are crucial to accurately estimating emulsifier exposure. Current research on the health effects of food additive emulsifiers are limited to in vitro and murine studies and small, acute studies in humans, and future research should focus on controlled human trials of longer duration.

RESUMEN

The modern food supply faces many challenges. The global population continues to grow and people are becoming wealthier, so the food production system must respond by creating enough high-quality food to feed everyone with minimal damage to our environment. The number of people suffering or dying from diet-related chronic diseases, such as obesity, diabetes, heart disease, stroke, and cancer, continues to rise, which is partly linked to overconsumption of highly processed foods, especially high-calorie or rapidly digestible foods. After falling for many years, the number of people suffering from starvation or malnutrition is rising, and thishas been exacerbated by the global COVID-19 pandemic. The highly integrated food supply chains that spread around the world are susceptible to disruptions due to policy changes, economic stresses, and natural disasters, as highlighted by the recent pandemic. In this perspective article, written by members of the Editorial Committee of the Annual Review of Food Science and Technology, we highlight some of the major challenges confronting the modern food supply chain as well as how innovations in policy and technology can be used to address them. Pertinent technological innovations include robotics, machine learning, artificial intelligence, advanced diagnostics, nanotechnology, biotechnology, gene editing, vertical farming, and soft matter physics. Many of these technologies are already being employed across the food chain by farmers, distributors, manufacturers, and consumers to improve the quality, nutrition, safety, and sustainability of the food supply. These innovations are required to stimulate the development and implementation of new technologies to ensure a more equitable, resilient, and efficient food production system. Where appropriate, these technologies should be carefully tested before widespread implementation so that proper risk-benefit analyses can be carried out. They can then be employed without causing unforeseen adverse consequences. Finally, it is important to actively engage all stakeholders involved in the food supply chain throughout the development and testing of these new technologies to support their adoption if proven safe and effective.

RESUMEN

BACKGROUND: Sustainable healthy diets are those dietary patterns that promote all dimensions of individuals' health and well-being; have low environmental pressure and impact; are accessible, affordable, safe, and equitable; and are culturally acceptable. The food environment, defined as the interface between the wider food system and consumer's food acquisition and consumption, is critical for ensuring equitable access to foods that are healthy, safe, affordable, and appealing. DISCUSSION: Current food environments are creating inequities, and sustainable healthy foods are generally more accessible for those of higher socioeconomic status. The physical, economic, and policy components of the food environment can all be acted on to promote sustainable healthy diets. Physical spaces can be modified to improve relative availability (ie, proximity) of food outlets that carry nutritious foods in low-income communities; to address economic access certain actions may improve affordability, such as fortification, preventing food loss through supply chain improvements; and commodity specific vouchers for fruits, vegetables, and legumes. Other policy actions that address accessibility to sustainable healthy foods are comprehensive marketing restrictions and easy-to-understand front-of-pack nutrition labels. While shaping food environments will require concerted action from all stakeholders, governments and private sector bear significant responsibility for ensuring equitable access to sustainable healthy diets.

RESUMEN

BACKGROUND: Healthy diets promote optimal growth and development and prevent malnutrition in all its forms, including undernutrition, obesity, and diet-related noncommunicable diseases (NCDs). OBJECTIVE: This background paper for the International Expert Consultation on Sustainable Healthy Diets characterizes healthy diets and their implications for food system sustainability. METHODS: Three complementary approaches to defining healthy diets are compared: World Health Organization (WHO) guidelines or recommendations developed between 1996 and 2019; 2017 Global Burden of Disease (GBD) risk factor study estimates of diet-related risk-outcome associations; and analyses associating indices of whole dietary patterns with health outcomes in population studies and clinical trials. RESULTS: World Health Organization dietary recommendations are global reference points for preventing undernutrition and reducing NCD risks; they emphasize increasing intakes of fruits, vegetables (excepting starchy root vegetables), legumes, nuts, and whole grains; limiting energy intake from free sugars and total fats; consuming unsaturated rather than saturated or trans fats; and limiting salt intake. Global Burden of Disease findings align well with WHO recommendations but include some additional risk factors such as high consumption of processed meat; this approach quantifies contributions of diet-related risks to the NCD burden. Evidence on whole dietary patterns supports WHO and GBD findings and raises concerns about potential adverse health effects of foods with high levels of industrial processing. CONCLUSIONS: Implied shifts toward plant foods and away from animal foods (excepting fish and seafood), and for changes in food production systems have direct relevance to the sustainability agenda.
