RESUMO

BACKGROUND: Historically, the Andean people have experienced uncertainty in terms of the availability of food resources because of climatic and ecological variations that are typical of mountainous environments. Risk management strategies, including the diversified and complementary use and management of species and ecosystems at different elevations, have faced such uncertainty. The current effects of climate change on food security motivate studies on subsistence adaptative strategies. TEK offers extraordinary experience and local biocultural memory to meet present and future needs. From an ethnoecological perspective, we aim to identify the variety of local foods in Andean communities, their cultural and nutritional value for local people, their use frequencies, and their forms to obtain them from different environments, productive systems, and interchanges. We expected to identify traditional Andean diversified subsistence patterns despite the pressure of modern food and interchange systems. METHODS: This study was conducted in two communities in the highlands of the Department of Huánuco, Peru. We conducted 24 semistructured interviews with households sampled through the snowball method. We asked about their daily life food, plant and animal components of diet, frequencies and seasons in which they are consumed, and ways to obtain them. We complemented the information through ethnobotanical collection of wild, weedy, and ruderal edible plants and records on domestic and wild animals included in the diet. RESULTS: We recorded 37 crop species, 13 domestic animals, 151 wild, weedy, and ruderal food plant species, the 3 most commonly consumed wild animals, and 52 processed products obtained from local stores and markets. The main crops are potato and maize, while the main domestic animals included in the diet are cattle, pigs, and sheep. Rice, pasta, and bread are the main raw and processed foods included in the diet. Crops represent nearly half of the food consumed and purchased (in kg/year), and tubers and cereals provide most of the kilocalories, carbohydrates and proteins. Wild, weedy, and ruderal plants are consumed in relatively low amounts and at relatively low frequencies per species, but overall, they constitute a significant proportion of the kg of annually consumed food (14.4% in Cani and 9.6% in Monte Azul). Knowledge and use of these resources play a key role in local cuisine and nutrition. CONCLUSION: The current food patterns studied are based on diverse diets, including multiple feedstuffs, sources, and practices to obtain them, which reflects the traditional Andean subsistence pattern. The increasing adoption of processed food has influenced the declining consumption of local food, mainly among young people. Communication and policies to promote local food, emphasizing the role of wild plants and their adequate consumption, and provide information on their nutritional value are recommended to support efforts toward food sovereignty and conservation of Andean biocultural diversity.

RESUMO

BACKGROUND: In past years, thousands of protein-polysaccharide complexes have been investigated to modify protein characteristics and functionality in food systems. However, the interaction between pea protein isolate (PPI) and soluble soybean polysaccharide (SSPS) has not been thoroughly characterized yet. RESULTS: In the present study, the phase behavior of PPI and SSPS mixtures was analyzed as a function of PPI:SSPS mixing ratio (1:1 to 1:0.10) and pH (7.0 to 2.0), showing that these biopolymers could be electrostatically assembled at 1:1 to 1:0.25 mixing ratios and 4.0 to 3.0 pH values. Then, the characteristics of the PPI-SSPS complexes were studied before and after heating (90 °C and 30 min) by ζ-potential, surface hydrophobicity, protein solubility, particle size distribution and physical stability for 56 days. By lowering the pH and PPI:SSPS mixing ratio, the complexes showed increased solubility, changed 𝜁-potential and higher physical stability. By heating, the complexes presented increased hydrophobicity and physical stability. CONCLUSION: Overall, PPI-SSPS complexes increased the protein solubility, reduced the particle size, and changed both the ζ-potential and the surface hydrophobicity with respect to PPI control, allowing stabilization of the colloidal system and broadening the possible applications of these high-quality proteins in acidic food systems. © 2024 Society of Chemical Industry.

RESUMO

Diet shift is an opportunity to mitigate the impacts of food systems, which are responsible for about a third of greenhouse gas (GHG) emissions globally and exert various environmental pressures on ecosystems. This study evaluates the mitigation potential of both global and local environmental impacts through dietary changes within the Brazilian context. Furthermore, the study aims to identify the potential benefits and trade-offs that may arise from these dietary transitions, thus providing a comprehensive analysis of the overall environmental implications. To this end, a life cycle assessment (LCA) was performed to evaluate the environmental impacts of a conventional diet in Brazil and seven alternatives, namely adjusted-EAT-Lancet, pescatarian, vegetarian, entomophagic (insect-based food), mycoprotein (microbial-based food), and synthetic (cell-based food) diets. Results indicate a substantial mitigation potential for GHG emissions (4-9 kg CO2e/cap/day) (39 % to 86 %) and land use (4-9 m2/cap/day) (38 % to 82 %) through a diet shift from a conventional diet to any of the seven alternative diets. However, certain trade-offs exist. A diet shift demonstrates no mitigation potential of soil acidification, and opportunities to reduce water eutrophication (0.02-0.2 g Pe/cap/day) (2 % to 24 %) and water consumption (0.2-0.5 m3/cap/day) (7 % to 14 %) were only found by completely substituting animal products for insect-based food, microbial-based food, and cell-based food. This study highlights the considerable potential of dietary changes to mitigate global environmental impacts associated with food systems. By revealing opportunities and challenges, this study supports science-based decision-making and guides efforts toward sustainable and environmentally friendly food consumption patterns.

RESUMO

This study identified food deserts and swamps, investigating their associations with socioeconomic and demographic conditions. This ecological study was conducted using data from urban census tracts in the city of Recife, which were considered the unit of analysis. Information on food retail was obtained from government sources in 2019. Census tracts below the 25th percentile in the density of healthy food retail (i.e., those that predominantly sell natural or minimally processed foods, mixed businesses, and super- and hypermarkets) were classified as food deserts. Census tracts above the 25th percentile in the density of unhealthy food retail (i.e., those selling primarily ultra-processed foods) were considered food swamps. The socioeconomic and demographic conditions of the census tracts were evaluated using variables from the 2010 census (per capita income, average income, race, literacy of the head of household, and the availability of essential services) and the Health Vulnerability Index. Census tracts considered food deserts (28.5%) were more vulnerable, characterized by lower income and access to essential services, more illiterate residents and more minorities (Black/Indigenous/mixed race). Food swamps (73.47%) were more prevalent in less vulnerable neighbourhoods characterized by higher percentages of literate residents and Whites, greater purchasing power, and better basic sanitation. The characteristics of Recife's food deserts and swamps demonstrate social inequalities in the food environment. Public facilities could play a vital role in promoting healthy eating within food deserts. Additionally, future implementation of taxes on ultra-processed foods and the provision of tax subsidies to natural or minimally processed food sellers might contribute to fostering healthier dietary choices.

RESUMO

Background: Tuvalu is a Pacific Island country within the small island developing states that has observed a significant and alarming increase in obesity rates over the past 40 years, affecting ∼60 %-70 % of the current population. Objectives: This study aimed to investigate the association between food patterns and the proportion of obesity in a Pacific Island country. Methods: The 2022 COMmunity-based Behavior and Attitude survey in Tuvalu (COMBAT) included 985 adults with complete data on sociodemographic information and the frequency of consumption of 25 common foods. A latent class analysis determined 4 food patterns. Bayesian multilevel logistic and linear regression models estimated the association between food patterns and the proportion of obesity [body mass index (BMI) ≥30 kg/m2], severe obesity (BMI ≥40 kg/m2), and weight (kg), adjusting for potential confounders and accounting for clustering by region. Results: The latent class analysis revealed 4 food patterns with an entropy of 0.94 and an average posterior probability of class assignment for each individual of 0.97, described as follows: 1) local: locally produced foods with moderate food diversity (proportion of individuals = 28 %); 2) diverse-local: local with greater food diversity (17 %); 3) restricted-imported: more imported with restricted diversity (29 %); and 4) imported: heavily imported with high diversity (26 %). Compared to those following the diverse-local pattern, the odds of having obesity were greater for those classified with the imported pattern [odds ratio (OR): 2.52; 95 % credible interval (CrI): 1.59, 3.99], restricted-imported pattern (OR: 1.89; 95 % CrI: 1.59, 3.99), and local pattern (OR: 1.54; 95 % CrI: 0.94, 2.50). Similar trends were observed for severe obesity while body weight was positively associated with both restricted-imported and imported food patterns. Conclusions: The high consumption of imported foods, together with the low consumption of plant-based foods and protein-rich foods, could be a relevant modifiable lifestyle factor explaining the high levels of obesity and severe obesity in Tuvalu, a Pacific Island country.

RESUMO

BACKGROUND: An increasingly industrialized food system has marginalized local, traditional food cultures in Puerto Rico (PR). Recent efforts to decolonize diets have promoted local food intake; however, how resulting dietary patterns may influence cardiometabolic disease remains unknown. OBJECTIVES: This study aimed to 1) identify dietary patterns in PR and 2) determine their associations with metabolic syndrome (MetS) and its components. METHODS: Data were obtained from participants (30-75 y) in PROSPECT (PR Observational Study of Psychosocial, Environmental, and Chronic Disease Trends; n = 989). Dietary patterns were derived using partial least squares analysis with food frequency questionnaire data, using nutrients associated with local food purchasing (dietary fiber, magnesium, saturated fat) as response variables. MetS was classified using harmonized criteria from clinical and laboratory measures and medication use. Fully adjusted generalized linear models tested associations between tertiles of dietary patterns and MetS. RESULTS: Approximately half (52%) of the participants were classified with MetS. Four dietary patterns were revealed: conventional (legumes, coffee, and dairy), industrialized starch and meat-centric (red/processed meats, pasta, and starchy roots), industrialized sugar-centric (rice, sugary beverages, and refined grains), and neo-traditional (local plants and seafood). Individuals in the highest (compared with lowest) tertile of the industrialized starch and meat-centric dietary pattern had higher mean waist circumference (102 compared with 99 cm) (P = 0.01), fasting glucose (106 compared with 98 mg/dL) (P = 0.019), and systolic blood pressure (123 compared with 119 mmHg) (P = 0.022). Individuals in the highest (compared with lowest) tertile of the neo-traditional diet were 0.69 (0.49, 0.97) times less likely to have MetS (P = 0.035) and had 4.1 cm lower mean waist circumference (P = 0.002). CONCLUSIONS: Promoting a neo-traditional diet and curbing industrialized starch and meat-centric diets may improve cardiometabolic health in PR. Results can guide local food promotion as a healthful, decolonizing approach in island settings.

RESUMO

During adolescence, many young people gain greater food choice agency but also become increasingly exposed and susceptible to environmental pressures that influence their food choices. This coincides with increased nutritional needs, especially for girls. In urban Colombia, adolescent diets are often high in undesirable foods and low in nutritious foods, contributing to overweight and micronutrient deficiencies. This study aimed to explore the potential of improving diet quality using food-based recommendations (FBRs) within the parameters of local food systems and adolescents' existing dietary patterns to inform context-specific programmatic responses to malnutrition. We applied linear programming analysis to dietary data from 13- to 20-year-old girls in Medellin to identify problem nutrients, local micronutrient sources, and promising FBRs. Iron and, to a lesser extent, calcium targets were difficult to meet using optimized diets based on local foods, especially for 13- to 17-year-olds. High habitual consumption of foods with excessive salt, fat, or sugar provided >5% of micronutrients in optimized diets. Otherwise, significant micronutrient sources included legumes, meat, dairy, bread, potatoes, and fruit. FBRs met targets for 10 micronutrients but only 32%-39% recommended nutrient intake for iron. FBRs, including occasionally consumed foods and supplements, met all intake targets for less cost, indicating a need to increase access to nutrient-dense products.

RESUMO

Agri-food social-ecological systems (AFSES) embrace complex interactions and processes of food production, processing, and commercialization that are subject to constant changes. This study develops a heuristic approach using the adaptive cycle (AC) and a transformation potential measure to identify the historical trajectory of a coffee AFSES at a watershed scale in Copalita, Mexico, over 40 years from 1980 to 2020. Primary information was collected through semistructured interviews. The results show that the system interactions depend on economic, social, and environmental stressors and shocks affecting different temporal and spatial scales. The cumulative effects of driving forces and adaptive strategies have influenced the system to not complete the AC phases. Additionally, the results show that some adaptive strategies can become new stressors with time. Driving forces, adaptive strategies, tipping points, trade-offs and interactions within the AFSES could be identified as the main aspects defining system resilience.

RESUMO

Changes in food systems during the last decades fostered the establishment of global food networks based on exchanges between countries with different income levels. Recent studies explored configuration and factors associated with trade networks of specific food items during limited periods; however, there is lack of evidence on evolution of trade networks of foods for human consumption and its potential effects on population nutritional status. We present the evolution of the global trade network of foods for human consumption from 1986 to 2020, according to country income level, and we explore potential effects of country network centrality and globalization processes on the prevalence of overweight and obesity. Results show intensification of international food trade and globalization processes in the period of analysis with implications for population nutritional status worldwide.

RESUMO

Reducir, reutilizar y reciclar, "regla de las tres R", son estrategias que promueven una actitud responsable hacia el medioambiente y contribuyen al desarrollo sostenible. El objetivo de esta revisión fue analizar las publicaciones científicas generadas en Chile en el área de las pérdidas y desperdicios de alimentos (PDA), con enfoque en su cuantificación y basadas en "la regla de las tres R". Se realizó una búsqueda de literatura en tres bases de datos: Web of Science, Pubmed y Scopus. Los artículos originales seleccionados se clasificaron según tipo de acción, etapa de la cadena de suministro de alimentos, grupo de alimentos, cuantificación de PDA y tipo de estrategia (reducción, reutilización o reciclaje). Se encontraron 5 artículos de revisión y 31 artículos originales. La revalorización de subproductos agroindustriales fue la principal acción involucrada en los estudios de PDA (n= 22). El tipo de subproducto también fue analizado, y se encontró que los compuestos fenólicos provenientes de frutales son los más estudiados. Solo el 32% (12/31) de los artículos reportaron información sobre cuantificación de PDA. La revalorización de subproductos sumada a la recuperación de alimentos para producción de energía (n= 4) y de compostaje (n= 2) hacen que el reciclaje sea la estrategia más investigada. Estos antecedentes evidencian la necesidad de complementar la investigación nacional a nivel de acciones que apunten más hacia la reducción y reutilización de PDA y su cuantificación. Este conocimiento permitirá establecer líneas base y planes de monitoreo que contribuyan al cumplimiento de los Objetivos de Desarrollo Sostenible en Chile.


Reduce, reuse, and recycle "the 3Rs rule" are strategies that promote a responsible attitude towards the environment and contribute to sustainable development. The objective of this review was to analyze the scientific publications generated in Chile in the area of food loss and waste (FLW), with a focus on its quantification and based on "the 3Rs rule". A literature search was carried out in three databases: Web of Science, Pubmed, and Scopus. The selected original articles were classified according to the type of action, stage of the food supply chain, food group, FLW quantification, and type of strategy (reduction, reuse, or recycling). Five review articles and 31 original articles were found. The revalorization of agro-industrial by-products was the main initiative involved in the FLW studies (n= 22). The type of by-product was also analyzed, and it was found that the phenolic compounds from fruits are the most studied. Only 32% (12/31) of the articles reported information on FLW quantification. The revalorization of by-products added to food recovery for energy production (n= 4) and composting (n= 2) make recycling the most researched strategy. These antecedents show the need to complement the national research at the level of actions that point more towards reducing and reusing of FLW and its quantification. This knowledge will allow the establishment of baselines and monitoring plans that contribute to the fulfillment of the Sustainable Development Goals in Chile.

RESUMO

In Honduras, as in many settings between 2020 and 2022, food security was affected by the COVID-19 pandemic, climate change, and conflicts-what some refer to as "The Three Cs." These challenges have had overlapping impacts on food supply chains, food assistance programs, food prices, household purchasing power, physical access to food, and food acceptability. This article applies a food system disruption analysis-adapted from a fault tree analysis originally developed for a municipal context in the United States-to the context of Honduras to systematically examine how the Three Cs affected food availability, accessibility, and acceptability. This article demonstrates the value of approaching food security through a disruption analysis, especially for settings impacted by multiple, interconnected, ongoing crises.

RESUMO

The cattle sector is strategic for both the economic development and food security of Africa, but the low availability and quality of forage puts the most vulnerable population at risk. Hybrid forages are an alternative for enhancing both food security and sustainability of the sector but adoption levels are still low in Africa, which is related to various factors such as the availability of seeds. This document analyzes potential markets for new interspecific hybrids of Urochloa and potential hybrids of Megathyrsus maximus, adapted to the environmental conditions of eastern and partially western Africa, applying a four-step methodology based on estimating (i) required forage amounts for each country according to its dairy herd, (ii) potential hectares for forage cultivation based on (i), (iii) hectares that can be covered by the two hybrids of interest according to a Target Population of Environment approach, and (iv) potential market values for each country and hybrid. The results show a potential market of 414,388 ha for new interspecific hybrids of Urochloa and 528,409 ha for potential hybrids of Megathyrsus maximus, with approximate annual values of 73.5 and 101.1 million dollars, respectively. Ethiopia, Tanzania, and Kenya hold a market share of 70% for Urochloa, and South Sudan, Ethiopia, and Tanzania a 67% market share for Megathyrsus maximus. The results will help different actors in decision-making, i.e., regarding private sector investments in forage seed commercialization or public sector incentives supporting adoption processes, and thus contribute to increasing food security and sustainability in the region.

RESUMO

La preservación de la triada salud, bienestar y desarrollo del potencial del individuo descansa sobre una adecuada alimentación. Esta revisión pretende abordar algunos elementos a considerar ante una inminente actualización de las guías alimentarias hacia la sostenibilidad. La transformación de los sistemas alimentarios es una prioridad, dada la relación entre estos y la mejora de la salud poblacional y no solo de la salud ambiental. Un consumo responsable con dietas de calidad beneficia a la sociedad local e internacional, la ecología y la economía y las guías alimentarias siguen siendo la herramienta para llevar a la práctica las diferentes recomendaciones en materia alimentaria, alineadas con los principios de la Organización Mundial de la Salud y el desarrollo sostenible. La comparación entre las guías alimentarias existentes mostró algunos elementos útiles para su actualización con enfoque sostenible, siendo ellos: el contexto, el propósito, la necesidad de armonización, el significado de la sostenibilidad, la inclusión y el impacto sobre el ambiente-salud-producción. La actualización de las guías alimentarias es útil y necesaria para brindar estrategias y respuestas oportunas ante una población cada vez más responsable de su autocuidado y de su papel de cara a la preservación del medio ambiente para las futuras generaciones. Desafíos tan importantes como el incremento en el consumo de alimentos de origen vegetal, la preferencia por pescado o ave frente a la de carnes rojas y la reducción de las pérdidas y el desperdicio de alimentos y el equilibrio entre beneficios nutricionales y ambientales siguen siendo los principales hitos en la actualización de guías alimentarias basadas en la sostenibilidad(AU)


The preservation of the triad of health, well-being and development of the individual's potential rests on adequate nutrition. This review aims to address some elements to consider in the face of an imminent update of dietary guidelines towards sustainability. The transformation of food systems is a priority, given the relationship between these and the improvement of population health and not only environmental health. Responsible consumption with quality diets benefits local and international society, ecology and the economy, and dietary guidelines continue to be the tool to put into practice the different recommendations on food matters aligned with the principles of the World Health Organization and sustainable development. The comparison between existing dietary guidelines showed some useful elements for their update with a sustainable approach, these being: the context, the purpose, the need for harmonization, the meaning of sustainability, inclusion and the impact on the environment-health-production. The update of dietary guidelines is useful and necessary to provide timely strategies and responses to a population that is increasingly responsible for its self-care and its role in preserving the environment for future generations. Challenges as important as the increase in the consumption of plant-based foods, the preference for fish or poultry over red meat, the reduction of food losses and waste, and the balance between nutritional and environmental benefits remain the main milestones in the updating of food guidelines based on sustainability(AU)

RESUMO

Resumo O ato de cozinhar engloba dimensões culturais, ambientais, sociais, econômicas e políticas, bem como compõe as atividades contidas em um sistema alimentar, sendo uma ação promotora de diálogos e transformações. Este estudo objetiva descrever e analisar elementos cotidianos relacionados ao cozinhar e suas relações com o sistema alimentar, a partir da experiência de um grupo de mulheres agricultoras urbanas da zona leste da cidade de São Paulo. Foram utilizados os mapas corporais narrados, método de pesquisa visual criativo no qual, por meio da realização do desenho dos contornos corporais dos participantes, foram produzidos dados visuais e orais sobre os significados do ato de cozinhar. Participaram do estudo sete mulheres, que desenvolvem ações relacionadas à agricultura e ao cozinhar. Os dados gerados foram analisados por meio de análise temática. O ato de cozinhar se mostrou como um conector do campo à mesa, fortalecendo e sendo fortalecido pelas práticas da agricultura urbana e periurbana, sendo uma interessante ferramenta para promover saúde, contemplando o bem-estar biopsicossocial em consonância com questões de sustentabilidade social, econômica e ambiental. Compreender tal conexão possibilita apoiar políticas públicas para a promoção de sistemas alimentares sustentáveis e o enfrentamento aos desafios do antropoceno.


Abstract Cooking encompasses cultural, environmental, social, economic, and political dimensions, as well as composes the activities contained in a food system and promoting dialogues and transformations. This study aims to describe and to analyze everyday elements related to cooking and its relationship with the food system based on the experience of a group of female urban farmers in the east side of the city of São Paulo. Body-map storytelling was used, a creative visual research method, in which, by drawing the participant's body contours, visual and oral data were produced on the meanings of cooking. Seven women participated in this study, who develop actions related to agriculture and cooking. The generated data were analyzed using thematic analysis. Cooking proved to be a connector from the field to the table, strengthening and being strengthened by the practices of urban and peri-urban farming, and is an interesting tool to promote health, contemplating biopsychosocial well-being in line with issues of social, economic, and environmental sustainability. Understanding this connection enables to support public policies to promote sustainable food systems and facing the challenges of the Anthropocene.

RESUMO

Obesity is a critical medical condition worldwide that is increasingly involved with nutritional derangements associated with micronutrient deficiencies, including iron, zinc, calcium, magnesium, selenium, and vitamins A, C, D, and E. Nutritional deficiencies in obesity are mainly caused by poor-quality diets, higher nutrient requirements, alterations in micronutrient metabolism, and invasive obesity treatments. The current conventional agricultural system is designed for intensive food production, focusing on food quantity rather than food quality, consuming excessive agricultural inputs, and producing nutrient-deficient foods, thus generating severe health and environmental problems; agricultural food products may worsen obesity-related malnutrition. Therefore, modern agriculture is adopting new biofortification technologies to combat micronutrient deficiencies and improve agricultural productivity and sustainability. Biofertilization and nanofertilization practices are increasingly used due to their efficiency, safety, and reduced environmental impact. Biofertilizers are preparations of PGP-microorganisms that promote plant growth by influencing plant metabolism and improving the nutrient uptake, and nanofertilizers consist of synthesized nanoparticles with unique physicochemical properties that are capable of increasing plant nutrition and enriching agricultural products. This review presents the current micronutrient deficiencies associated with obesity, the modern unsustainable agri-food system contributing to obesity progression, and the development of bio- and nanofertilizers capable of biofortifying agri-food crops with micronutrients commonly deficient in patients with obesity.

RESUMO

The integration of the circular economy in agriculture has promoted sustainable innovation in food production systems such as horticulture. The present paper illustrates how horticulture is transitioning to the circular economy. This research field's performance approaches and trends were assessed through a bibliometric and text-mining analysis of the literature. Our findings revealed that circular horticulture is a recent research field that is constantly growing. Its approach has been neither systemic nor integrative but fragmented. Bioeconomy, urban agriculture, recycled nutrients, biochar, fertigation, and desalination have been positioned as research hotspots. Vegetables and fruits are the most studied crops. Resource circulation has focused primarily on biowaste recovery to provide benefits such as biofertilizers and linear-substrate substitutes, and on water reuse for the establishment of hydroponic systems. The One Health approach is scarcely explored and, therefore, weakly articulated, wherein the absence of assessment methodologies encompassing the health of ecosystems, animals, and people is a notable limitation. Science-policy interfaces between One Health and food systems need to be improved. Lastly, greenhouse technologies are aligned with bioenergy, sustainable materials, and sensing technologies. Challenges and directions for future research have been raised to promote the redesign of horticultural production systems, integrating long-term circularity.

RESUMO

The COVID-19 pandemic has disproportionally affected women in Honduras in terms of loss of employment and income opportunities, access to healthcare services, and increased poverty and food insecurity. The pre-pandemic gender inequalities in Honduras have resulted in harsher conditions for women since the onset of the pandemic. Early reports indicate that women have lost employment and incomes and have been burdened by other effects of the pandemic, such as more household work, childcare activities, and home schooling. Marginal groups such as indigenous women face greater challenges because of the structural and systemic inequalities which have existed for a long time. The impact of the COVID-19 pandemic has also differed across geographic areas and between rural and urban settings. In addition to the pandemic, the economic outlook for women in Honduras has worsened since the impact of Hurricanes Eta and Iota in November 2020, which displaced over a million people. The agricultural sector was devastated, and infrastructure was severely damaged. The recovery efforts have been slow because of the COVID-19 pandemic. This paper explores the root causes of gender inequalities and how it affects women's food security and health.

RESUMO

A paradigm shift is required to transform food systems, so they are more equitable, environmentally friendly, and healthy. This requires acknowledging which factors change or maintain the status quo. In this commentary, we reflect upon the Cervantes et al study findings and discuss the role of power dynamics in transforming food systems. This is directly relevant to Mexico in terms of (i) relationships between food system actors; (ii) the role of socio-economic political context; and (iii) opportunities for policy coherence and transformative food systems approaches. We suggest that the power dynamics that drive the food produced, sold, and consumed should be recognised in all (inter)national governance decision-making. The 2021 United Nations Food System Summit - when interest groups were perceived to overly influence the summit proceedings - is an example of how neglecting the role of power dynamics can undermine and slow food system transformation.

RESUMO

Fruits and vegetables wastes (e.g., peel fractions, pulps, pomace, and seeds) represent ~16% of total food waste and contribute ~6% to global greenhouse gas emissions. The diversity of the fruit-horticultural production in several developing countries and the excess of certain fruits or vegetables in the months of greatest production offer unique opportunities for adding value to these wastes (co-products). Within the scope of the Circular Economy, valorization of such wastes for the production of innovative bio-ingredients can open great market opportunities if efficiently exploited. In this context, this review deals with the current situation of wastes arising from fruits and vegetables (availability, characterization) as sources of valuable ingredients (fiber, polyphenols, pigments) suitable to be incorporated into food, pharmaceutical and cosmeceutical products. In addition, an integral and systematic approach including the sustainable technologies generally used at both lab and industrial scale for efficient extraction of bioactive compounds from fruits and vegetables wastes are addressed. Overall, this review provides a general updated overview regarding the situation of fruits and vegetables chain supplies in the post-pandemic era, offering an integrative perspective that goes beyond the recovery of fiber and phytochemicals from the previous mentioned wastes and focuses on whole processes and in their social and economic impacts.
