The International Network of Food Data Systems, a global network coordinated by the Food and Agriculture Organization that sets standards for food composition data. INFOODS connects regional data centres and national nutrient database compilers, promoting consistent methods for describing foods, sampling, analysis, and data documentation. Its guidelines make nutrient values comparable across countries, supporting dietary assessment, labelling, and nutrition policy worldwide. The network also runs training programmes that build capacity in regions where food composition data are scarce. Reliable, harmonised food data underpin almost every evidence-based decision in nutrition, from guidelines to fortification programmes.
