Book Description
Schools are an attractive entry point to improve children’s diets, as their eating habits can be shaped during childhood and the information disseminated from school can reach adults through children. We implemented a cluster-randomized trial in 12 schools in peri-urban Viet Nam to assess if two school-based interventions increased knowledge of healthy diets among children and their parents, as well as children’s consumption of healthy foods. First, children were given lessons about food before school lunch and encouraged to share the lessons with their parents. Second, children were provided with healthy snacks for five weeks to reinforce messages about healthy eating. We found that in the short term, the nutrition lessons raised the knowledge index score of the children by 0.35 standard deviation. After six months, this intervention retained its effectiveness only for the children who also received free access to fruit, emphasizing the linkage between knowledge and practice. By itself, free access to fruit at school increased the children’s daily fruit consumption by half a portion, but not at the expense of home fruit consumption. Access to healthy foods at school can therefore be an effective measure to raise children’s healthy consumption. Child-parent communication was not a reliable channel for knowledge dissemination in our setting.

Book Description
Suboptimal diets are a major risk factor for avoidable death and disease in low- and middle-income countries. Evidence shows that some foods or food components (e.g., processed red meat, saturated fat, salt, sugar) significantly elevate the risk of noncommunicable diseases and mortality, while others protect health (e.g., vegetables, fruits, pulses, nuts/seeds, fish, whole grains—referred to in this document as “protective foods”). We used household surveys to compare dietary patterns in Ethiopia, Kenya, Tanzania, and Uganda to the EAT-Lancet healthy reference diet and to quantify and explain consumption gaps for nutritious foods. Compared to the EAT-Lancet healthy reference diet, consumption gaps for pulses and nuts/seeds, vegetables, and fruits are large for both poor and rich consumers in rural and urban areas in the four countries studied, while consumption gaps for meat, fish, and eggs and dairy foods are much larger for lower income groups. Food expenditures of most households in these four countries are far too low to allow consumption of the healthy reference diet; animal-source foods and vegetables are the largest cost components of food expenditures, although quantities consumed of both food groups are much lower than the EAT-Lancet healthy reference diet. Income elasticities of demand for pulses and nuts/seeds and vegetables are often low or moderate, suggesting weak consumer preference for these foods, while income elasticities for fruits and animal-source foods are relatively high. Income growth alone will not solve dietary problems in East Africa; in addition to supply-side interventions to improve affordability, special interventions are required to increase consumer demand for underappreciated protective (nutritious) foods such as pulses and nuts/seeds and vegetables.

Book Description
Myanmar has endured multiple crises in recent years — including COVID-19, global price instability, the 2021 coup, and widespread conflict — that have disrupted and even reversed a decade of economic development. Household welfare has declined severely, with more than 3 million people displaced and many more affected by high food price inflation and worsening diets. Yet Myanmar’s agrifood production and exports have proved surprisingly resilient. Myanmar’s Agrifood System: Historical Development, Recent Shocks, Future Opportunities provides critical analyses and insights into the agrifood system’s evolution, current state, and future potential. This work fills an important knowledge gap for one of Southeast Asia’s major agricultural economies — one largely closed to empirical research for many years. It is the culmination of a decade of rigorous empirical research on Myanmar’s agrifood system, including through the recent crises. Written by IFPRI researchers and colleagues from Michigan State University, the book’s insights can serve as a to guide immediate humanitarian assistance and inform future growth strategies, once a sustainable resolution to the current crisis is found that ensures lasting peace and good governance.

Book Description
Malnutrition, largely attributable to poor diets among both the rich and poor, presents a growing challenge in Nigeria. This brief considers the obstacles to food security and better nutrition, particularly the country’s macroeconomic instability, widespread poverty, and the need for greater investment and policy coherence to support dietary diversity. The authors describe how a policy shift to focus on consumer needs can transform the agrifood system to deliver healthier and more affordable diets for all Nigerians, as well as better and more secure rural livelihoods.

Book Description
In the decade prior to the COVID-19 pandemic, Myanmar was in the midst of a dietary transition driven by rapid economic growth and urbanization. In this study, we first use national survey data to compare household diets in 2015 to the healthy diet recommendations of food-based dietary guidelines adapted for Myanmar, as well as estimated nutrient consumption relative to recommended intakes. We use these food group and nutrient consumption gaps to estimate a new measure of multidimensional dietary deprivation developed by Pauw et al. (2022), and a novel extension of that index to nutrient deprivation. Both deprivation indices are strongly negatively correlated with total household expenditure. We then use food demand estimation to estimate income and own price elasticities, which reveal strong preferences for animal-sourced foods, but weaker preferences for vegetables and pulses. Expenditure data also point to strong demand for oils/fats – a problem observed throughout developing Asia (Pingali and Abraham 2022) – and for food away from home, which partially explains the rising burden of overweight/obesity in Myanmar. Moreover, since most nutrient-dense foods are income- and price-elastic, estimated income elasticities suggest that recent declines in household income and increases in food prices in Myanmar will result in declining dietary diversity. We show that this is indeed the case utilizing household phone surveys conducted in recent years. We first use a food vendor survey to show that the cost of a healthy diet increased by 61 percent between September 2021 and September 2022. Next, we analyze a rural Dry Zone panel survey implemented 10 times over 2020-2021 and find that maternal and child dietary diversity both declined significantly as Myanmar’s economic situation deteriorated. Then, in a nationally representative phone survey conducted quarterly in 2022 over a period of rapid food inflation, we find further deterioration in diet quality among adults, but no deterioration among children 6-23 months of age, suggesting parents may be trying to insulate their children from the worst effects of the crisis. Finally, we conclude the paper by discussing policy and program options in very difficult political circumstances. Malnutrition is a multidimensional problem requiring multisectoral solutions, but at present the breakdown in the provision of even basic services makes significant progress highly unlikely, and reversing the recent deterioration in dietary quality and nutrition will surely require resolution of Myanmar’s political crisis. In the interim, we discuss three potentially effective types of interventions: (1) rice fortification to reduce micronutrient deficiencies; (2) homestead food production to improve dietary quality in farm households and rural and peri-urban communities; and (3) nutrition-sensitive social protection for vulnerable mothers and young children, with transfers ideally accompanied by nutrition education interventions.

Book Description
This detailed and comprehensive study examines nutrition and health in the World Health Organization (WHO) Eastern Mediterranean Region, presenting the six game-changing food systems actions proposed by the WHO and the progress of their implementation in the region. The WHO Eastern Mediterranean Region is a particularly complex place to study: an area of economic contrasts with changing dietary patterns and stark differences between high levels of malnutrition and a prevalence of overweight and obesity. As a result, actions to improve the nutritional situation of the population are urgently sought. The strategies explored in this book offer a unique opportunity to change food systems all over the world, addressing aspects including sustainable food production, the impact of marketing and labelling on behaviour, and the effect of global events such as climate change, war and the COVID-19 pandemic. Reshaping Food Systems is an essential read at a time when malnutrition in all its forms, including undernourishment, micronutrient deficiencies and overweight and obesity, pose a serious threat to global health, and is of particular interest for policymakers working in nutrition and public health.
