CcalWerte

CcalWerte is a term used in nutrition software and dietary data models to refer to a curated set of caloric values assigned to foods. The name combines "Werte" (values) in German with "Ccal," a common shorthand for calories, and is used to denote standardized energy data that underpins energy accounting in apps and databases.

A CcalWerte dataset typically includes fields such as energy_kcal_per_100g, carbohydrates_g, protein_g, fat_g, fiber_g, alcohol_g, and serving_size. Values are commonly expressed per 100 grams or per standard portion, and may be accompanied by uncertainty estimates or notes on preparation (raw vs cooked). Macros are based on general energy coefficients (approximately 4 kcal/g for carbohydrates and protein, 9 kcal/g for fat, 7 kcal/g for alcohol).

Sources: CcalWerte values are usually derived from national and international nutrition databases (for example USDA FoodData Central, EuroFIR, or local equivalents) and are updated to reflect product formulations and culinary preparation. They are used by meal-planning software, calorie counters, and dietary-management systems to compute total energy intake and to balance nutrients in meals and menus.

Example entries: Apple, raw, 100 g: energy 52 kcal, carbohydrates 14 g, protein 0.3 g, fat 0.2 g, fiber 2.4 g. Banana, raw, 100 g: energy 89 kcal, carbohydrates 23 g, protein 1.1 g, fat 0.3 g, fiber 2.6 g.

Limitations: Real-world values vary by variety, origin, ripeness, and preparation. CcalWerte provides a practical approximation rather than an exact measure and should be used in conjunction with product labels and databases that account for regional differences.
