The Food Database (FOODB) is the world’s largest and most comprehensive resource on food constituents, chemistry, and biology. It is a freely accessible electronic database that provides detailed information about the chemical constituents found in food, designed for applications in nutrition, food science, dietary planning, and general education. FOODB contains extensive data on food compounds, including their chemical properties, biological activities, dietary sources, and health effects. The database integrates information from multiple sources, linking food compound data to other relevant databases such as "HMDB", "PubChem", "CHEBI", "KEGG", and "NCBI_Taxonomy". FOODB supports a wide range of search functionalities, allowing users to perform text, sequence, chemical structure, and relational queries.

FOODB (The Food Database) offers detailed information about both macronutrients and micronutrients, including many of the constituents that give foods their flavor, color, taste, texture, and aroma. Each chemical entry in FOODB contains more than 100 separate data fields covering detailed compositional, biochemical, and physiological information obtained from the literature. This includes data on the compound’s nomenclature, description, structure, chemical class, physico-chemical properties, food sources, color, aroma, taste, physiological effects, presumptive health effects (from published studies), and concentrations in various foods. FOODB not only houses data on food compounds but also provides information about the foods containing these compounds, their nutritional profiles, and the dietary patterns associated with their consumption. The database classifies food compounds based on their chemical nature and biological relevance, helping users to better understand the role of these compounds in nutrition and health.

FOODB is an invaluable tool for researchers, dietitians, food scientists, and educators, offering a wealth of information on the chemical makeup of foods and their implications for human health. The database is extensively linked to other resources, facilitating easy access to related information and enabling a holistic view of food composition and its impact on nutrition and health. Users can browse or search FOODB by food source, name, descriptors, function, or concentrations. Depending on individual preferences, users can view the content of FOODB from the Food Browse section Food Browse (listing foods by their chemical composition) or the Compound Browse section Compound Browse (listing chemicals by their food sources).
