Children under the age of two are not getting the food or nutrients they need to thrive and grow well, leading to irreversible developmental harm, according to a new report released by Unicef Tuesday. The crisis of children's diets in early life – released ahead of the UN Food Systems Summit this week – warns that rising poverty, inequality, conflict, climate-related disasters, and health emergencies such as the Covid-19 pandemic, are contributing to an ongoing nutrition crisis among the world's youngest that has shown little sign of improvement in the last ten years. "The report's findings are clear: When the stakes are highest, millions of young children are being fed to fail," said Unicef Executive Director Henrietta Fore. "Poor nutritional intake in the first two years of life can irreversibly harm children's rapidly growing bodies and brains, impacting their schooling, job prospects and futures. While we have known this for years, there has been little progress on providing the right kind of nutritious and safe foods for the young. The ongoing Covid-19 disruptions could make the situation much worse." In an analysis of 91 countries, the report finds that only half of children aged 6-23 months are being fed the minimum recommended number of meals a day, while just a third consume the minimum number of food groups they need to thrive. Further analysis of 50 countries with available trend data reveals these poor feeding patterns have persisted throughout the last decade. As Covid-19 continues to disrupt essential services and drives more families into poverty, the report finds that the pandemic is affecting how families feed their children. For example, a survey conducted among urban households in Jakarta found that half of the families have been forced to reduce nutritious food purchases. As a result, the percentage of children consuming the minimum recommended number of food groups fell by a third in 2020, compared to 2018.

An insufficient intake of nutrients found in vegetables, fruits, eggs, fish and meat needed to support growth at an early age puts children at risk of poor brain development, weak learning, low immunity, increased infections and, potentially, death. Children under the age of two are most vulnerable to all forms of malnutrition – stunting, wasting, micronutrient deficiencies, and overweight and obesity – as a result of poor diets, due to their greater need for essential nutrients per kilogram of body weight than at any other time in life. Globally, Unicef estimates that more than half of children under the age of five with wasting – around 23 million children – are younger than two years of age, while the prevalence of stunting increases rapidly between six months and two years, as children's diets fail to keep pace with their growing nutritional needs. According to the report, children aged 6-23 months living in rural areas or from poorer households are significantly more likely to be fed poor diets compared to their urban or wealthier peers. In 2020, for example, the proportion of children fed the minimum number of recommended food groups was twice as high in urban areas (39 per cent) than in rural areas (23 per cent). To deliver nutritious, safe, and affordable diets to every child, the report calls for governments, donors, civil society organisations and development actors to work hand-in-hand to transform food, health and social protection systems by leading key actions, including increasing the availability and affordability of nutritious foods – such as fruits, vegetables, eggs, fish meat and fortified foods – by incentivising their production, distribution and retailing. The report notes that progress is possible with investment. In Latin America and the Caribbean, for example, almost two thirds (62 per cent) of children aged 6–23 months are fed a minimally diverse diet, while in Eastern and Southern Africa (24 per cent), West and Central Africa (21 per cent) and South Asia (19 per cent), less than one in four young children are being fed a minimally diverse diet. In all regions, investments are needed to ensure that all children benefit from the diverse diets they need to prevent all forms of malnutrition, and grow, develop and learn to their full potential. "Children cannot survive or thrive on calories alone," said Fore. "Only by joining forces with governments, the private sector, civil society, development and humanitarian partners, and families can we transform food systems and unlock nutritious, safe and affordable diets for every child."
