Energy in food
The energy value of a food indicates how much energy the human body can gain through metabolism. The energy value is specified in kilojoules (kJ) per 100 g or 100 ml. In addition, the specification is often in kilocalories (kcal) . Fddb.info indicates both values.
The total energy value of a food product results from the addition of the energy content of each nutrient components. These are defined as follows:
|1 g fat||37 kJ (9 kcal)|
|1 g carbohydrates||17 kJ (4 kcal)|
|1 g protein||17 kJ (4 kcal)|
|1 g alcohol (ethanol)||29 kJ (7 kcal)|
|1 g polyhydric alcohols (polyols)||10 kJ (2.4 kcal)|
|1 g dietary fibre||8 kJ (2 kcal)|
For example, fat has a higher calorific value than the same amount of carbohydrates.
