Nutrient contents in foods can vary significantly because:

of environmental, genetic and processing influences such as feed, soil, climate, genetic resources (varieties/cultivars, breeds), storage conditions, processing, fortification and market share; each country has its own consumption pattern resulting in country-specific foods, recipes and brand-name foods (commercial foods with the same brand-name can have varying composition due to taste or fortification regulations across borders) food biodiversity highly influences the composition of foods: nutrient values may vary up to 1000 times among different varieties of the same foods. This means that the nutrient content of foods can vary as much among foods as among varieties of the same food.

Therefore, each country has specific data needs as they have different compositions of their foods, even if some people think that foods have similar composition among countries due to globalization.

INFOODS also stands as a forum through which international harmonization and support for food composition activities can be achieved and advocated. Its objectives are:

development of international criteria for judging the quality of data on food composition; identification of existing sources of useful data on food composition; promotion of the generation, acquisition, and dissemination of new data on the composition of foods, beverages and their ingredients that meet the criteria developed; and facilitating, on a world-wide basis, the access, retrieval, interchange, and general harmonization of food composition data.
