Calorific value

Energy in food

Description

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.
