'Whatever we have is what we eat': How marginalised urban populations in the Philippines and Thailand experienced their food environments, food security and diets through COVID-19.

This qualitative cross-country comparative study investigated the lived experience of marginalised urban populations (unemployed, daily wage earners/street vendors, and internal/external migrants) in Manila (Philippines) and Bangkok (Thailand) on food environments, food security and diets during COVID-19. Semi-structured interviews were conducted with individuals (n = 59) in April-May 2022. Thematic analysis revealed loss of income and strict mobility restrictions (Philippines) as key drivers of dietary changes and hunger.

Cost and affordability of a healthy diet for urban populations in Thailand and the Philippines before and during the COVID-19 pandemic.

Background: The coronavirus disease 2019 (COVID-19) pandemic severely affected global food security, but analyses of its impact on the cost and affordability of a healthy diet are limited. This study examines the immediate effect of the COVID-19 pandemic on the cost and affordability of a healthy diet among urban households in Bangkok, Thailand and Manila, the Philippines.

Methods: We used official food price and household income and food expenditure data from the national statistics offices.

Holding no-one back: The Nutrition Equity Framework in theory and practice.

Equity remains poorly conceptualised in current nutrition frameworks and policy approaches. We draw on existing literatures to present a novel Nutrition Equity Framework (NEF) that can be used to identify priorities for nutrition research and action. The framework illustrates how social and political processes structure the food, health and care environments most important to nutrition.

Stories of change in nutrition: lessons from a new generation of studies from Africa, Asia and Europe.

How does nutrition improve? We need to understand better what drives both positive and negative change in different contexts, and what more can be done to reduce malnutrition. Since 2015, the Stories of Change in Nutrition studies have analysed and documented experiences in many different African and Asian countries, to foster empirically-grounded experiential learning across contexts. This article provides an overview of findings from 14 studies undertaken in nine countries in South Asia, sub-Saharan Africa, and Europe between 2017 and 2021.

The continued effects of COVID-19 on the lives and livelihoods of vegetable farmers in India.

India experienced a rapid rise in COVID-19 infections from March 2021. States imposed varying levels of lockdowns and curfews to curb the spread of the disease. These restrictions severely affected the functioning of food systems.

Revisiting food security in 2021: an overview of the past year.

Articles published in Food Security in 2021 are reviewed, showing a wide range of topics covered. Many articles are directly linked with "food" and associated terms such as "nutritive", "nutrition", "dietary", and "health". Another important group is linked with (food) "production" and a range of connected terms including: "irrigation", "cultivated", "organic", "varieties", "crop", "vegetable", and "land".

Integrating Nutrition Actions in Service Delivery: The Practices of Frontline Workers in Uganda.

Background: Integrating nutrition actions into service delivery in different policy sectors is an increasing concern. Nutrition literature recognizes the discrepancies existing between policies as adopted and actual service delivery. This study applies a street-level bureaucracy (SLB) perspective to understand frontline workers' practices that enact or impede nutrition integration in services and the conditions galvanizing them.

Vegetables for Healthy Diets in Low- and Middle-Income Countries: A Scoping Review of the Food Systems Literature.

Background: Vegetables are an essential element in healthy diets, but intakes are low around the world and there is a lack of systematic knowledge on how to improve diets through food system approaches.

Methods: This scoping review assessed how studies of food systems for healthy diets have addressed the role of vegetables in low- and middle-income countries. We apply the PRISMA guidelines for scoping reviews to narratively map the literature to an accepted food systems framework and identify research gaps.

Stories of change in nutrition from Africa and Asia: an introduction to a special series in Food Security.

Malnutrition in all its forms continues to be a massive global challenge, and the past decade has seen a growing political attention to addressing malnutrition in different contexts. What has been largely missing so far, and is in growing demand from countries, is tangible, practical and rigorous insights and lessons (from other countries or contexts) on how to translate this burgeoning political momentum into effective policies and programme implementation strategies - and ultimately impact on the ground. This new climate of learning from experience and evidence led to the launch in 2015 of the Stories of Change initiative.

Equity in agriculture-nutrition-health research: a scoping review.

Links among agriculture, nutrition, and health (ANH) are established, but the role of inequity is less understood. In this scoping review, we aimed to understand the range of ways that ANH research addresses inequity issues in low- and middle-income countries. We used PRISMA guidelines to structure our study.

The Basic Determinants of Malnutrition: Resources, Structures, Ideas and Power.

Background: While child undernutrition is improving overall, different population groups are experiencing different outcomes. What sets some groups apart is their experience of the 'basic determinants' of malnutrition, that underpin the 'immediate' and 'underlying' determinants, and that have been much less studied, defined and understood.

Methods: We undertook a qualitative narrative review based in two sets of ideas: nutrition's basic determinants as laid out in the original United Nations Children's Fund (UNICEF) framework, and critical concepts emerging from development studies.

Addressing Malnutrition: The Importance of Political Economy Analysis of Power.

Background: The exercise of power is central to understanding global health and its policy and governance processes, including how food systems operate and shape population nutrition. However, the issue of power in food systems has been little explored empirically or theoretically to date. In this article, we review previous work on understanding power in addressing malnutrition as part of food systems that could be used in taking this issue further in future food systems research.

Determinants of household food security and dietary diversity during the COVID-19 pandemic in Bangladesh.

Objectives: The study aimed to determine the associated factors of household food security (HFS) and household dietary diversity (HDD) during the COVID-19 pandemic in Bangladesh.

Design: Both online survey and face-to-face interviews were employed in this cross-sectional study. The Household Food Security Scale and Household Dietary Diversity Score were used to access HFS and HDD, respectively.

Conflict of Interest in Nutrition: Where's the Power? Comment on "Towards Preventing and Managing Conflict of Interest in Nutrition Policy? An Analysis of Submissions to a Consultation on a Draft WHO Tool".

Actual or perceived conflict of interests (COIs) among public and private actors in the field of nutrition must be managed. Ralston et al expose sharply contrasting views on the new World Health Organization (WHO) COI management tool, highlighting the contested nature of global debates. Both the WHO COI tool and the Ralston et al paper are largely quiet on aspects of power among different actors, however, which we argue is integral to these conflicts.

Mapping disruption and resilience mechanisms in food systems.

This opinion article results from a collective analysis by the Editorial Board of Food Security. It is motivated by the ongoing covid-19 global epidemic, but expands to a broader view on the crises that disrupt food systems and threaten food security, locally to globally. Beyond the public health crisis it is causing, the current global pandemic is impacting food systems, locally and globally.

Food system disruption: initial livelihood and dietary effects of COVID-19 on vegetable producers in India.

Disruption to food systems and impacts on livelihoods and diets have been brought into sharp focus by the COVID-19 pandemic. We aimed to investigate effects of this multi-layered shock on production, sales, prices, incomes and diets for vegetable farmers in India as both producers and consumers of nutrient-dense foods. We undertook a rapid telephone survey with 448 farmers in 4 states, in one of the first studies to document the early impacts of the pandemic and policy responses on farming households.

Advocacy coalitions and the transfer of nutrition policy to Zambia.

Stunted growth in children and multisectoral action to address it are dominant ideas in the international nutrition community today, and this study finds that these ideas are increasingly evident over time in nutrition policy in Zambia, with stunting largely displacing other framings of nutrition. This study is based on key informant interviews (70 interviews with 61 interviewees), policy document review, and social network mapping, with iterative data collection and analysis taking place over 6 years (2011-2016). Analysis was based on two established political science theories: policy transfer theory and the Advocacy Coalition Framework.

Changes in the policy environment for infant and young child feeding in Vietnam, Bangladesh, and Ethiopia, and the role of targeted advocacy.

Background: There is limited literature examining shifts in policy environments for nutrition and infant and young child feeding (IYCF) over time, and on the potential contribution of targeted advocacy to improved policy environments in low- and middle-income countries. This study tracked changes in the policy environment over a four-year period in three countries, and examined the role of targeted nutrition and IYCF advocacy strategies by a global initiative.

Methods: Qualitative methods, including key informant interviews, social network mapping, document and literature review, and event tracking, were used to gather data on nutrition and IYCF policies and programs, actor networks, and perceptions and salience of nutrition as an issue in 2010 and 2014 in Bangladesh, Ethiopia, and Vietnam.

Progress in improving provincial plans for nutrition through targeted technical assistance and local advocacy in Vietnam.

Vietnam has been decentralizing nutrition planning to provinces, which could help with local relevance and accountability. Assessment in 2009 found a continuing top-down approach, limited human capacity, and difficulty in integrating multiple sectors. Alive and Thrive (A&T) provided targeted assistance and capacity-building for 15 provincial plans for nutrition (PPNs).

Measuring the Food Access Dimension of Food Security: A Critical Review and Mapping of Indicators.

Background: With food security now a top priority for many governments and for the global development community, there is heightened awareness of the need to improve our understanding and measurement of food security.

Objective: To bring clarity in the assessment of the food access dimension of food security at the household and individual level.

Methods: For the most commonly used indicators, we reviewed their original purpose and construction, at what levels (household or individual) they were designed to be used, what components (quality, quantity, safety, and cultural acceptability) they were intended to reflect, and whether or not they have been tested for validity and comparability across contexts.

Agriculture and nutrition in India: mapping evidence to pathways.

In India, progress against undernutrition has been slow. Given its importance for income generation, improving diets, care practices, and maternal health, the agriculture sector is widely regarded as playing an important role in accelerating the reduction in undernutrition. This paper comprehensively maps existing evidence along agriculture-nutrition pathways in India and assesses both the quality and coverage of the existing literature.

An economic evaluation of adaptive e-learning devices to promote weight loss via dietary change for people with obesity.

Background: The prevalence of obesity is over 25 % in many developed countries. Obesity is strongly associated with an increased risk of fatal and chronic conditions such as cardiovascular disease and type 2 diabetes. Therefore it has become a major public health concern for many economies.

Assessing the effectiveness and cost effectiveness of adaptive e-Learning to improve dietary behaviour: protocol for a systematic review.

Background: The composition of habitual diets is associated with adverse or protective effects on aspects of health. Consequently, UK public health policy strongly advocates dietary change for the improvement of population health and emphasises the importance of individual empowerment to improve health. A new and evolving area in the promotion of dietary behavioural change is e-Learning, the use of interactive electronic media to facilitate teaching and learning on a range of issues, including diet and health.
