Pacific Island Countries and Territories (PICTs) are experiencing a Diet-Related Non-Communicable Disease (DR-NCD) health crisis(1). Increasing rates of DR-NCDs such as Type 2 diabetes and cardiovascular disease have been linked to dietary transitions and increasing food insecurity in the region(2). Anthropogenic climate change has also been identified as a significant threat to food security in PICTs(3). Additionally, the impacts of the COVID-19 Pandemic have been identified as both a contributor to food insecurity in the region and as an opportunity to transform PICT food systems and reduce rates of DR-NCDs(4). Yet, the drivers of dietary change, food security and agricultural practices in peripheral PICT communities are not well documented or understood. To determine how these drivers may change in the future and the impacts this may have on Pacific peoples, a deeper understanding of the historical and contemporary drivers of change is necessary. The aim of this scoping review was to collate existing information to improve this understanding, by mapping key factors evident in the literature that underpin the links between DR-NCDs and food security with a focus on women in PICT peripheral communities, to better clarify the challenges, working definitions and conceptual boundaries in the research area. The review maps where research has been conducted geographically and how the links between DR-NCDs and food security in PICTs have been investigated over time and identifies projections and suggestions for the future. The scoping review was conducted in accordance with a pre-defined protocol available online(5). A total of 476 peer-reviewed sources and 126 grey literature sources were identified by the initial search criteria. Two independent researchers completed title/abstract and full text screening using Covidence, and data extraction using a data extraction tool. The resulting data was quantified in table format, with common themes and ideas presented qualitatively. Sources spanned all sectors of PICT food systems with a heavy focus on production from fisheries and agriculture. Most PICTs were represented in the findings. Many drivers of change within food systems were identified, some of which included the impacts of anthropogenic climate change, the COVID-19 pandemic, and urbanisation. The drivers impacted all four pillars of food security, and many were directly or indirectly related to dietary and lifestyle changes associated with DR-NCD risk factors. This data is accompanied by an interpretation of results and a narrative summary. These results provide a useful platform to further explore the drivers of dietary change, food security, agricultural practices and DR-NCD’s in this region.

The goal of this commentary is to expose the situation of Food and Nutrition Security (FNS) in Brazil in the context of the COVID-19 pandemic by providing a critical analysis of this scenario and suggesting ways to move forward. When COVID-19 arrived in Brazil, a crisis scenario that incorporated economic, social and political aspects became highly visible. This scenario fostered unemployment, poverty and hunger. Besides that, it exposed multiple vulnerabilities that were getting worse over the past few years prior to the pandemic. In this context, COVID-19 found in Brazil a fertile ground for its dissemination and community transmission. The impacts of the suspension of many commercial activities and other economic sectors due to the pandemic were quickly felt socially and economically in Brazil. Some of the actions carried out by the Brazilian government included the emergency aid payment and exemption from payment of energy bills for vulnerable individuals, release of funds for programmes for the direct purchase of food from family farmers, delivery of school food kits directly to students despite the closure of schools and publication of sanitary rules for the operation of restaurants. However, these actions are still insufficient, slow and not sufficiently coordinated to contain the progress of the food and nutritional insecurity crisis in Brazil. The COVID-19 pandemic highlights the urgency for the Brazilian government to again prioritise the FNS agenda. This includes implementing mechanisms to ensure the Human Right to Adequate Food and expanding existing FNS programmes.

India’s main food and nutrition security programme, the Public Distribution System (PDS), provides subsidised rice and sugar to deprived households. Using longitudinal data from Young Lives for Indian children (n = 2,944) aged 5 to 16 years, we assessed whether PDS subsidies skewed diets towards sugar and rice consumption, increasing risk of stunting (low height-for-age). Linear regression models were used to quantify additional rice and sugar consumption associated with accessing the PDS, and the association with stunting linked to consumption. Controlling for sociodemographics, accessing the PDS was positively, significantly associated with consumption of rice (30g/day) and sugar (7.05g/day). There was no evidence that this increase corresponded to nutritional improvements. Each 100g increase in daily rice intake was associated with a lower height-for-age z-score (HAZ) and no decline in stunting. Results were robust to alternative model specifications. There was no evidence that receipt of PDS rice and sugar was associated with improvements in child nutrition.

Presently, close to 1 billion people suffer from hunger and food insecurity. Statistics in Kenya indicates that over 10 million people suffer from chronic food insecurity and poor nutrition, 2–4 million people require emergency food assistance at any given time with nearly 30 % of Kenya's children being undernourished, 35 % stunted while micro-nutrient deficiency is wide spread. Key among the challenges contributing to inadequate foods include lack of certified seeds, seasonal production (rain-fed), high post-harvest losses and wastages, poor transportation, low value additions which reduce their market competitiveness. The present paper examines some of the underlying causes for high food wastage experience in Kenya and the associated challenges in addressing these problems. The paper also provides an overview of some of the basic solutions that have been recommended by various stakeholders. However, in spite of the recent efforts made to mitigate food wastage, there is still an urgent need to address these gaps through participatory, innovative community based interventions that will create resilience to climate change and enhance livelihoods of smallholder farmers in diverse ecosystems.

Improvement in the nutritional quality of Bangladeshi rice-based diets is sought through increasing the amounts of vegetables, fish and legumes consumed. The aim of the present study was to compare the effects of rice-based diets on selected parameters of Ca and P availability and retention in young, growing rats. The study was designed as a randomised balance trial with five diets, eight animals per diet, and two balance periods of 1 week each. Apart from diet 1, which was a pure rice diet, the other four diets were composite diets and included the leafy vegetable, amaranth leaves (Amaranthus gangeticus), the small fish, mola (Amblypharyngodon mola), and lentils (Lens culinaris) in different amounts to simulate the average rural rice-based diet, the recommended diet, the recommended diet diluted with starch, and the recommended diet excluding amaranth leaves. The inclusion of amaranth leaves, mola and lentils significantly improved N and growth retention in the rats compared with the pure rice diet. However, a minor addition of amaranth (0·66 g/100 g DM) significantly reduced the fractional Ca absorption and retention. Femur bone mass and Ca and P densities were significantly lower in the rats fed the diets that included amaranth leaves. The observed inhibitory effect of the amaranth leaves on Ca absorption and utilisation was probably due to the oxalate content. It is concluded that the formulation of a recommended diet cannot be based only on nutrient content values of individual food components due to interactions between nutrients and anti-nutrients in the diet.
