voedseldatabase

A voedseldatabase is a structured collection of data about foods and their nutritional composition. It provides standardized, numerical values that support dietary assessment, nutrition labeling, product development, and public health policy. By compiling information on a wide range of foods, it enables comparison, meal planning, and research across populations.

Entries in a voedseldatabase typically include the food item or recipe, portion size, and nutrient values. Common data fields are energy (calories), macronutrients (carbohydrates, proteins, fats), fiber, sugars, and micronutrients (vitamins and minerals). Values are usually given per 100 grams or per serving, and data are accompanied by notes on measurement methods, data provenance, and sometimes allergen information, ingredients, and processing.

Data sources and maintenance vary by database but commonly combine laboratory analyses, recipe calculations, literature data, and manufacturer information. National and international efforts maintain and update the databases to reflect new products and changing formulations. Notable examples include the Dutch NEVO database (Nederlands Voedingsstoffenbestand) and the United States’ USDA FoodData Central, with other regions contributing their own resources. Data quality, coverage, and update frequency can differ, and researchers often cross-check multiple sources to fill gaps.

Applications of voedseldatabases include diet planning and counseling, epidemiological research, nutrition labeling, food product development, and regulatory surveillance. They are used by health professionals, researchers, app developers, policymakers, and educational organizations. Access is commonly public or semi-public, with data available for download or via APIs, though licensing terms and update schedules may vary.
