 Schools are when new generations start building a better future. Yet when children and adolescents don't have healthy diets, their growth and well-being is affected. Multisectoral food and nutrition programmes include school meals but go well beyond that. They build children's knowledge and skills through food and nutrition education to enable them and their families to take decisions and actions towards healthy diets. They support local economies by sourcing produce for school meals from small food producers. They can also nudge local food systems towards more sustainable practices for better nutrition, environment and biodiversity conservation. The Food and Agriculture Organisation of the United Nations in collaboration with other UN agencies helps countries put in place multisectoral approaches the policy and legal environments needed for effective school food and nutrition programmes. In Latin America and the Caribbean, FAO supported 17 countries towards this multisectoral approach and strengthened their school food and nutrition programmes and policies. Food and nutrition education has become part of the national education curriculum using school gardens as teaching tools. Civil society, parliamentarians, cooperatives and local communities are actively involved in these programmes. In Senegal and Ethiopia, governments and farmers were supported to ensure the supply of local nutritious foods to schools. In Ghana and Cambodia, FAO works with partners to improve the nutritional quality of school meals and children's diets through setting up minimum nutrition criteria for their school meals programmes linked to their food systems. Through school food and nutrition programmes, governments, small food producers, development partners and schools can all work together for better production, better nutrition, better environment and a better life for all, leaving no one behind.
